“The inventor of the bagpipes was inspired when he saw a man carrying an indignant, asthmatic pig under his arm.”

Alfred Hitchcock.

To no one’s great surprise, Fed Chairman Goldilocks  Powell yesterday said happily "Ahhh, this porridge is just right."

And with that, he let us all in on a big Fed secret, inflation at a 30 year high is transitory he said, and that the Fed might have to start to taper its bond purchases later in the year or it might not have to. It all depends on how the stock market’s doing, the US employment numbers.

And in on that big Fed secret, the stock bears all went back to bed and the stock bulls came out to play.

Chairman Powell would then have gone home except he was already there, this was a Zoom speech to a virtual Jackson Hole summit after all.

I have my doubts that this great inflation is going to be transitory, although industrial metal commodities are going to get a break next week from China’s announcement that they are going to sell off 150,000 tons of metals from their strategic reserves.

Powell sees taper by the end of the year, but says there’s ‘much ground to cover’ before rate hikes

Federal Reserve Chairman Jerome Powell indicated Friday that the central bank is likely to begin withdrawing some of its easy-money policies before the end of the year, though he still sees interest rate hikes off in the distance.

In a much-anticipated speech as part of the Fed’s annual Jackson Hole, Wyoming, symposium, Powell said the economy has reached a point where it no longer needs as much policy support.

That means the Fed likely will begin cutting the amount of bonds it buys each month before the end of the year, so long as economic progress continues. Based on statements from other central bank officials, a tapering announcement could come as soon as the Fed’s Sept. 21-22 meeting.

However, it does not mean that rate increases are looming.

“The timing and pace of the coming reduction in asset purchases will not be intended to carry a direct signal regarding the timing of interest rate liftoff, for which we have articulated a different and substantially more stringent test,” Powell said in prepared remarks for the virtual summit.

He added that while inflation is solidly around the Fed’s 2% target rate, “we have much ground to cover to reach maximum employment,” which is the second prong of the central bank’s dual mandate and necessary before rate hikes happen.

Markets reacted positively to Powell’s comments, sending major stock indexes to record highs while government bond yields moved lower.

Later in the day, Fed Vice Chairman Richard Clarida said he agrees with Powell’s remarks and expects tapering to being this year so long as the pace of labor gains continues, though neither official set a specific date for when the process will begin.

----Powell also devoted an extensive passage in the speech to explaining why he continues to think the current inflation rise is transitory and will drop eventually to the target level.

----At last year’s Jackson Hole summit, also held virtually, Powell outlined a bold new policy initiative in which the Fed committed to full and inclusive employment even if it meant allowing inflation to run hot for a while. Critics have charged that the policy is partially to blame for current price pressures at their highest levels in about 30 years.

China to Sell 150,000 Tons of Metals From Reserves on Sept. 1

Bloomberg News

China said it would release its third batch of metals from state reserves on Sept. 1 as part of its ongoing campaign to control prices and prevent commodities inflation from hurting growth.

The National Food and Strategic Reserves Administration said Friday it will sell 70,000 tons of aluminum, 50,000 tons of zinc, and 30,000 tons of copper, quantities in line with the two earlier auctions that took place in July.

A key jobs report in the week ahead could drive the next big market move

With Jackson Hole in the rear-view mirror, August’s employment report could be the next driver for markets.

Stocks gained in the past week, surging again to new highs Friday after a speech by Federal Reserve Chairman Jerome Powell. The chairman acknowledged that Fed officials expect to taper back their $120 billion a month bond-buying program this year, a first step toward reversing easy policy.

Powell was speaking at the Kansas City Fed’s annual Jackson Hole, Wyo. symposium, held virtually this year. He said the Fed has seen sufficient progress on inflation, but the labor market has not yet improved enough to start the taper.

----Powell’s speech was widely anticipated to clarify the Fed’s position on its $120 billion monthly bond purchases, after a number of Fed officials called for the start of a wind down.

Now, market focus shifts even more fiercely to jobs data, with the release Friday of the August employment report.

“For sure, the market is going to react,” said Jim Caron, head of macro strategies for global fixed income at Morgan Stanley Investment Management. “I think it’s important. I think the issue that they’re going to have is unemployment benefits don’t really run out until the beginning of September. It’s really not until you get the October jobs number that you get a more free look at September.”

The dollar index sank after Powell’s Friday morning speech, as stocks rallied to new highs and Treasury yields fell. Other data in the coming week includes consumer confidence Tuesday and Wednesday’s release of Institute for Supply Management manufacturing data and ADP’s private sector payroll data, a kind of preview for Friday’s government jobs report.

----Some market pros had expected an announcement on tapering from the Fed at its September meeting, but that view has now mostly changed to a November or December announcement. “Because of the uncertainty of delta, I think it will take more than the next jobs report,” said Diane Swonk, chief economist at Grant Thornton. “The disruption to jobs in particular is if schools have to close again.”

Economists polled by Dow Jones expect 750,000 jobs were created in August and the unemployment rate fell to 5.2%.

Next, anything China can do we can do too, says India. But is a digital currency needed or wise? China began a partial test of a digital Yuan about two months ago.

India could begin trials for a digital rupee by December, central bank governor says

Published Fri, Aug 27 2021 4:18 AM EDT

The Reserve Bank of India may launch its first digital currency trial programs by December, central bank governor Shaktikanta Das told CNBC.

Central banks including those in China, Europe and the U.K. are exploring digital currencies that would be issued by them, either to commercial lenders or to the public directly.

They are called central bank digital currencies, or CBDC — legal tender in digital form, and are essentially the online version of their respective fiat currencies. In India’s case, that would be the digital rupee.

“We are being extremely careful about it because it’s completely a new product, not just for RBI, but globally,” Das told CNBC’s Tanvir Gill in a pre-recorded interview on Thursday.

The RBI is studying various aspects of a digital currency including its security, impact on India’s financial sector as well as how it would affect monetary policy and currency in circulation, according to the governor.

Das added that the central bank is also exploring the choice between having a centralized ledger for the digital currency or the so-called distributed ledger technology (DLT).

DLT refers to a digital database that allows multiple participants to access, share and record transactions simultaneously. A centralized ledger means the database is owned and operated by a single entity — in this case, the central bank.

“I think by the end of the year, we should be able to — we would be in a position, perhaps — to start our first trials,” Das told CNBC.

His deputy, T Rabi Shankar, last month said the central bank was working toward a “phased implemental strategy” for a digital currency.

---- The People’s Bank of China is leading the way, with real-world trials already in place across several cities.

Finally, as the USA and NATO end a 20 year war in Afghanistan, and on a weekend that Britain is expected to pull out its troops from Kabul Airport, remembering the world’s shortest, least costly war.

Personally, I prefer “shortest least costly wars” to wars like WW1, WW2, and longest of all Afghanistan, not that I’m volunteering, of course!

Anglo-Zanzibar War

The Anglo-Zanzibar War was a military conflict fought between the United Kingdom and the Zanzibar Sultanate on 27 August 1896. The conflict lasted between 38 and 45 minutes, marking it as the shortest recorded war in history.[3] The immediate cause of the war was the death of the pro-British Sultan Hamad bin Thuwaini on 25 August 1896 and the subsequent succession of Sultan Khalid bin Barghash. The British authorities preferred Hamud bin Muhammed, who was more favourable to British interests, as sultan.

In the agreement of 14 June 1890 instituting a British protectorate over Zanzibar, a candidate for accession to the sultanate should obtain the permission of the British consul,[4] and Khalid had not fulfilled this requirement. The British considered this a casus belli and sent an ultimatum to Khalid demanding that he order his forces to stand down and leave the palace. In response, Khalid called up his palace guard and barricaded himself inside the palace.

The ultimatum expired at 09:00 East Africa Time (EAT) on 27 August, by which time the British had gathered three cruisers, two gunboats, 150 marines and sailors, and 900 Zanzibaris in the harbour area. The Royal Navy contingent were under the command of Rear-Admiral Harry Rawson and the pro-Anglo Zanzibaris were commanded by Brigadier-General Lloyd Mathews of the Zanzibar army (who was also the First Minister of Zanzibar).

Around 2,800 Zanzibaris defended the palace; most were recruited from the civilian population, but they also included the sultan's palace guard and several hundred of his servants and slaves. The defenders had several artillery pieces and machine guns, which were set in front of the palace sighted at the British ships. A bombardment, opened at 09:02, set the palace on fire and disabled the defending artillery. A small naval action took place, with the British sinking the Zanzibari royal yacht HHS Glasgow and two smaller vessels. Some shots were also fired ineffectually at the pro-British Zanzibari troops as they approached the palace. The flag at the palace was shot down and fire ceased at 09:46.

U.S. inflation gauge rose in July to highest level in 30 years

Aug. 27, 2021 / 10:42 AM

Aug. 27 (UPI) -- A key statistic the Federal Reserve uses to measure inflation increased by 3.6% in July, its largest increase in 30 years, the Commerce Department said Friday.

The department said the near 4% increase is compared to July 2020 and is the highest level since 1991.

The data comes from the department's core personal consumption expenditures price index, excluding food and energy prices.

The increase was in line with most analysts' expectations.

"The increase in personal income in July primarily reflected increases in government social benefits and compensation of employees," the department's report said.

"Within government social benefits, an increase in 'other' social benefits was partly offset by a decrease in unemployment insurance, reflecting a decrease in payments from the Pandemic Unemployment Compensation program."

Poor Monsoon May Hurt India Oilseed and Cotton Output, NCML Says

By Pratik Parija

27 August 2021, 09:02 BST

Production of oilseeds and cotton in India will probably drop this year as deficient monsoon rains in main growing areas have hit plantings, according to Siraj Chaudhry, managing director and chief executive officer of National Commodities Management Services Ltd.

“We started this monsoon season with high hopes and a lot of optimism,” Chaudhary said in an interview with Bloomberg Television’s Haslinda Amin and Rishaad Salamat, Friday. The country received good rainfall in June, the start of the four-month rainy period, but there have been disappointments after that, he said. 

There are some specific crops that have got affected, he said. Oilseed and cotton will see a drop in production as weaker rains have reduced their sowing areas, said Chaudhary, the head of the provider of post-harvest solutions such as procurement, storage, transportation, inspection and testing.

Rains in some areas of the western Gujarat state, a key producer of cotton, have been 50% lower than average during the monsoon season so far, while showers in parts of both Punjab and Rajasthan have been 22% below normal, according to the India Meteorological Department. Similarly, parts of Madhya Pradesh, a major soybean grower, have received 17% lower than average rainfall, it said. 

The monsoon, which waters more than half of the country’s farmland, is critical for agriculture as it also fills reservoirs for crops sown in the winter. It shapes the livelihood of millions of rural people and influences food prices. Patchy rainfall in the country, the second-largest producer of rice and wheat and top buyer of palm oil, often leads to lower crop output, higher imports of edible oils, firmer food prices and weaker economic growth.

Chaudhary said the current rain situation doesn’t warrant panic, but requires caution. The price management, especially of food items, was important, he said.

Covid-19 Corner             

This section will continue until it becomes unneeded.

Does the FDA think these data justify the first full approval of a covid-19 vaccine?

August 23, 2021

The FDA should demand adequate, controlled studies with long term follow up, and make data publicly available, before granting full approval to covid-19 vaccines, says Peter Doshi

On 28 July 2021, Pfizer and BioNTech posted updated results for their ongoing phase 3 covid-19 vaccine trial. The preprint came almost a year to the day after the historical trial commenced, and nearly four months since the companies announced vaccine efficacy estimates “up to six months.”

But you won’t find 10 month follow-up data here. While the preprint is new, the results it contains aren’t particularly up to date. In fact, the paper is based on the same data cut-off date (13 March 2021) as the 1 April press release, and its topline efficacy result is identical: 91.3% (95% CI 89.0 to 93.2) vaccine efficacy against symptomatic covid-19 through “up to six months of follow-up.”

The 20 page preprint matters because it represents the most detailed public account of the pivotal trial data Pfizer submitted in pursuit of the world’s first “full approval” of a coronavirus vaccine from the Food and Drug Administration. It deserves careful scrutiny.

The elephant named “waning immunity”

Since late last year, we’ve heard that Pfizer and Moderna’s vaccines are “95% effective” with even greater efficacy against severe disease (“100% effective,” Moderna said).

Whatever one thinks about the “95% effective” claims (my thoughts are here), even the most enthusiastic commentators have acknowledged that measuring vaccine efficacy two months after dosing says little about just how long vaccine-induced immunity will last. “We’re going to be looking very intently at the durability of protection,” Pfizer senior vice president William Gruber, an author on the recent preprint, told the FDA’s advisory committee last December.

The concern, of course, was decreased efficacy over time. “Waning immunity” is a known problem for influenza vaccines, with some studies showing near zero effectiveness after just three months, meaning a vaccine taken early may ultimately provide no protection by the time “flu season” arrives some months later. If vaccine efficacy wanes over time, the crucial question becomes what level of effectiveness will the vaccine provide when a person is actually exposed to the virus? Unlike covid vaccines, influenza vaccine performance has always been judged over a full season, not a couple months.

And so the recent reports from Israel’s Ministry of Health caught my eye. In early July, they reported that efficacy against infection and symptomatic disease “fell to 64%.” By late July it had fallen to 39% where Delta is the dominant strain. This is very low. For context, the FDA’s expectation is of “at least 50%” efficacy for any approvable vaccine.

Now Israel, which almost exclusively used Pfizer vaccine, has begun administering a third “booster” dose to all adults over 40. And starting 20 September 2021, the US plans to follow suit for all “fully vaccinated” adults eight months past their second dose.

Delta may not be responsible

Enter Pfizer’s preprint. As an RCT reporting “up to six months of follow-up,” it is notable that evidence of waning immunity was already visible in the data by the 13 March 2021 data cut-off.  

“From its peak post-dose 2,” the study authors write, “observed VE [vaccine efficacy] declined.” From 96% to 90% (from two months to <4 months), then to 84% (95% CI 75 to 90) “from four months to the data cut-off,” which, by my calculation (see footnote at the end of the piece), was about one month later.

But although this additional information was available to Pfizer in April, it was not published until the end of July.

And it’s hard to imagine how the Delta variant could play a real role here, for 77% of trial participants were from the United States, where Delta was not established until months after data cut-off.

Waning efficacy has the potential to be far more than a minor inconvenience; it can dramatically change the risk-benefit calculus. And whatever its cause—intrinsic properties of the vaccine, the circulation of new variants, some combination of the two, or something else—the bottom line is that vaccines need to be effective.

Until new clinical trials demonstrate that boosters increase efficacy above 50%, without increasing serious adverse events, it is unclear whether the 2-dose series would even meet the FDA’s approval standard at six or nine months.  

---- Despite the reference to “six month safety and efficacy” in the preprint’s title, the paper only reports on vaccine efficacy “up to six months,” but not from six months. This is not semantics, as it turns out only 7% of trial participants actually reached six months of blinded follow-up (“8% of BNT162b2 recipients and 6% of placebo recipients had ≥6 months follow-up post-dose 2.”) So despite this preprint appearing a year after the trial began, it provides no data on vaccine efficacy past six months, which is the period Israel says vaccine efficacy has dropped to 39%.

It is hard to imagine that the <10% of trial participants who remained blinded at six months (which presumably further dwindled after 13 March 2021) could constitute a reliable or valid sample to produce further findings. And the preprint does not report any demographic comparisons to justify future analyses.

---- Prior to the preprint, my view, along with a group of around 30 clinicians, scientists, and patient advocates, was that there were simply too many open questions about all covid-19 vaccines to support approving any this year. The preprint has, unfortunately, addressed very few of those open questions, and has raised some new ones.

I reiterate our call: “slow down and get the science right—there is no legitimate reason to hurry to grant a license to a coronavirus vaccine.”

FDA should be demanding that the companies complete the two year follow-up, as originally planned (even without a placebo group, much can still be learned about safety). They should demand adequate, controlled studies using patient outcomes in the now substantial population of people who have recovered from covid. And regulators should bolster public trust by helping ensure that everyone can access the underlying data.

Can what you eat save you from COVID-19?

“We have two epidemics: obesity and COVID-19,” said Dr. Mariela Glandt, a Harvard University and Columbia University-trained endocrinologist.

MAAYAN JAFFE-HOFFMAN   AUGUST 22, 2021 21:24

Could good nutrition save people from developing severe COVID-19?

According to experts in the field, nutrition is the biggest coronavirus risk factor that not enough people are talking about.

“We have two epidemics: obesity and COVID-19,” said Dr. Mariela Glandt, a Harvard University and Columbia University trained endocrinologist and nutritionist who now lives in Israel and runs a clinic for diabetics in Ramat Aviv.

She said, “As long as the pandemic is still going on, anyone who cares about their health should do everything they can to improve the risk factors that they control” – among them diet.

While eating right cannot prevent contracting coronavirus, optimal metabolic health can help prevent the negative impact of infection, several studies have shown. That’s because “good nutrition and maintenance of a healthy body weight is essential for adequate immune function, supporting resistance to infectious disease and reducing adverse outcomes in the event of illness,” according to Prof. Mona Boaz of the Department of Nutrition Sciences in the School of Health Sciences at Ariel University.

“A poor diet, like the modern American diet, with its junk food, ultra-processed starches and cheap fats, causes metabolic dysfunction that can be a disaster when it’s combined with the coronavirus,” Glandt wrote in an eBook titled How to Eat in the Time of COVID-19 that she recently published with Ross Wollen and Jessica Apple.

The book was published by ASweetLife, which describes itself as “the Internet’s trusted authority on the art of living well with diabetes.”

Severe COVID-19 – hospitalization, treatment in an intensive care unit, mechanical ventilation and even death – has been associated with higher body mass index, the Centers for Disease Control has said.

Specifically, obesity defined by BMI increases the odds of hospitalization by 76%, Boaz showed in a paper that is soon to be published but has not yet been peer reviewed. She said the likelihood of ICU admission increases by 67%, mechanical ventilation by 119% and death by 37% – all according to recent studies.

Moreover, a study that was published in the peer-reviewed journal PLOS One at the end of last month showed that people with high sugar values but who were not diagnosed with diabetes were also at risk of severe COVID-19 morbidity or mortality.

Remarkable density of new lithium battery promises massive range for EVs

Nick Lavars  August 24, 2021

For electric planes to really take off and for electric cars to travel far longer distances between charges, we'll need batteries that pack far more energy without becoming prohibitively heavy. A team in Germany has now demonstrated a new lithium-metal battery with a density well beyond the significant 500-Wh/kg benchmark and an ability to retain its performance across hundreds of cycles.

Today's lithium-ion batteries do a wonderful job of keeping the modern world running, from electric vehicles to smartphones, to laptop computers, but scientists see a lot of potential that could be unlocked through tweaks to their architecture. One of the more promising possibilities is swapping out the graphite used in one of the battery's electrodes for pure lithium metal, a material that can hold as much as 10 times the energy.

For this reason, lithium metal is hailed as a "dream material" by some battery researchers and may well help us break through a key bottleneck in energy storage, but stability issues have plagued the technology so far. Much of this relates to adverse reactions between the electrolyte solution, which carries the lithium ions, and the battery's two electrodes, the cathode and anode.

Among the many research groups working to solve this problem is a team at Karlsruhe Institute of Technology and Helmholtz Institute Ulm (HIU), who have come up with a design that largely sidesteps this problem. The researchers started off with what's described as a cobalt-poor, nickel-rich layered cathode (NCM88) and a commercially available organic electrolyte called LP30. While the cathode reached high energy density, instability soon took hold and storage capacity decreased as the battery was cycled.

“In the electrolyte LP30, particles crack on the cathode," explains Professor Stefano Passerini, Director of HIU. "Inside these cracks, the electrolyte reacts and damages the structure. In addition, a thick mossy lithium-containing layer forms on the anode.”

So the team swapped out the LP30 electrolyte for an alternative, and one that brought about profound gains in performance. Described as a non-volatile, poorly-flammable, dual-anion ionic liquid electrolyte (ILE), this ingredient proved to largely avoid the structural defects on the cathode and saved the battery from the fatal electrochemical reactions.

“With the help of ILE, structural modifications on the nickel-rich cathode can be reduced significantly,” says Dr. Guk-Tae Kim.

And the results are rightly described as "remarkable." The lithium-metal battery with this architecture had an energy density of 560 Wh/kg. For context, there are research consortiums dedicated to breaking through the 500-Wh/kg density threshold in order to power next-generation electric vehicles, while today's best-in-class lithium-ion batteries have energy densities of 250 to 300 Wh/kg.

Earlier this year we reported on a record-setting lithium metal battery with an energy-density of 350 Wh/kg, which retained 76 percent of its capacity over 600 cycles. In terms of longevity, the new lithium metal battery design also performed remarkably well, starting out with an initial storage capacity of 214 mAh/g in the cathode material and retaining 88 percent of that across 1,000 cycles.

In the countdown to August 31, its going to be a long, long weekend in Kabul.

13 U.S. service members killed, 18 wounded in attack near Kabul airport, Pentagon says

WASHINGTON — A thirteenth U.S. service member has died from his wounds and the number of injured has risen to 18 after two suicide bombers detonated explosives near Hamid Karzai International Airport in Kabul, Afghanistan, on Thursday.

The injured service members are being evacuated from Afghanistan on specially equipped C-17 aircraft with surgical units, a spokesperson for U.S. Central Command said Thursday evening.

U.S. Marine Gen. Kenneth McKenzie, commander of U.S. Central Command, said in a briefing earlier Thursday that a number of Afghan civilians were also killed, but he was not able to provide a precise number.

The explosions took place near the airport’s Abbey Gate and the Baron Hotel immediately adjacent, McKenzie said. Several gunmen opened fire on civilians and military forces after the explosion at Abbey Gate, he said.

The general, who oversees the U.S. military’s operations in the region, said that the Pentagon is working to determine attribution for the attack but added that the current assessment is that the bombers are affiliated with ISIS.

ISIS later claimed responsibility for the attack.

McKenzie said that the U.S. is still monitoring “extremely active threats” to the airport that range from suicide bombers to rocket attacks. McKenzie said that despite the attack, the U.S. emergency evacuation mission continues.

Secretary of Defense Lloyd Austin expressed his condolences in a statement Thursday and condemned the attack that “took their lives at the very moment these troops were trying to save the lives of others.”

----The president warned that staying longer in Afghanistan carries serious risks for foreign troops and civilians. Biden said ISIS-K, an Afghanistan-based affiliate of the terror group, presents a growing threat to the airport.

“Every day we’re on the ground is another day we know that ISIS-K is seeking to target the airport and attack both U.S. and allied forces and innocent civilians,” he said.

The Taliban said earlier Tuesday that the group will no longer allow Afghan nationals to leave the country on evacuation flights nor will they accept an extension of the withdrawal deadline beyond the end of the month.

“We are not in favor of allowing Afghans to leave,” Taliban spokesman Zabihullah Mujahid told reporters during a news conference Tuesday.

“They [the Americans] have the opportunity, they have all the resources, they can take all the people that belong to them, but we are not going to allow Afghans to leave and we will not extend the deadline,” he said. Evacuations carried out by foreign forces after Aug. 31 would be a “violation” of a Biden administration promise to end the U.S. military’s mission in the country, Mujahid said.

In other news, business news, it’s Fed Chairman Powell’s big day. Supposedly, he get’s to tell all the rest of us minions when interest rates go up, by how much and what it will mean for the US economy.

My guess is that he will largely pass on the opportunity to open up. Despite trillions upon trillions of new Magic Money Tree fiat money with trillions more still to come, the US economy is still to fragile and weak to try for normality.

The casino stock bubbles would burst, an Everest debt mountain would start to default, though on the upside, inflation would finally prove to be “transitory.”

The pressure is on for Powell and the Federal Reserve to manage the exit from ultra-easy policies

For the Federal Reserve, implementing the easiest monetary policy in the institution’s history was tough enough. Getting out will be no treat, either.

That is what the central bank faces on its road ahead.

Investors on Friday will hear more on what Fed Chairman Jerome Powell thinks about the economy. They’re also expecting to get at least a few more clues on how he will guide the central bank’s exit from the measures it took to rescue the nation’s economy from the Covid-19 pandemic. He will deliver a speech in conjunction with the Fed’s annual Jackson Hole conference, which again will be held virtually this year.

First on the Fed’s docket is pulling back on the money printing – the $120 billion or so of bonds it buys each month to stimulate demand and drive down long-term interest rates.

After that, the road gets rougher.

At some point, the Fed will look to raise short-term interest rates off the near-zero anchor where they’ve sat since March 2020. Getting rates back to normal didn’t end well for the Fed the last time it attempted to do so from 2015-18, as it had to stop in mid-cycle amid a slumping economy.

Hence, markets could be excused for being at least a little nervous this time around. The Fed not only has to turn around its most-aggressive easing policies ever, it must do so with precision and hopes that it doesn’t break anything in the process.

“Every Fed change in monetary policy is important,” TD Securities global head of rates strategy Priya Misra said. “But I think it’s particularly more meaningful today because we know growth is slowing and the Fed is trying to exit.”

Indeed, the economy is still well within a strong recovery from the depths of the pandemic, which yielded the steepest but shortest recession in U.S. history. But the rebound has seemed to at least be stalling. The Citi Economic Surprise Index, which measures actual data against Wall Street estimates, was at a record high in mid-July. But the index has now slumped to levels last seen in June 2020.

Fed officials themselves expect noticeably slower growth in the years ahead at a time when both monetary and fiscal policy will be tighter. That raises more questions about whether Powell and his cohorts can get the exit right.

Misgivings in the market

“Are they exiting at the right place? Are they exiting at the right time, at the right magnitude? Given the slowing of the economy, we have questions around both,” Misra said. “The market is pricing in a policy mistake.”

What Misra means by a policy mistake is that the current pricing in fed funds futures — the market that trades around the Fed’s rate moves — is indicating the Fed central bank will only be able to raise its rate a few times to maybe 1.25%. Then, it will have to stop as growth stalls.

Asia-Pacific markets trade mixed ahead of Fed’s Jackson Hole

SINGAPORE — Asia-Pacific markets traded mixed on Friday as investors remained cautious ahead of the Federal Reserve’s annual Jackson Hole symposium where Fed Chair Jerome Powell is due to speak.

In Australia, the benchmark ASX 200 retraced early losses of almost 0.3% to trade near flat. The heavily weighted financials subindex reversed course from a 0.4% loss to trade up 0.21%. Energy and materials sectors were down 0.18% and 0.28%, respectively.

The Nikkei 225 erased some of its earlier declines, but the Japanese index was still down 0.33% while the Topix index fell 0.36%. South Korea’s Kospi turned positive and traded up 0.32% and the Hang Seng Index in Hong Kong rose 0.55%.

Chinese mainland shares also rose: The Shanghai composite was up 0.53% while the Shenzhen component added 0.45%.

The highly anticipated Jackson Hole symposium from the Fed will be held virtually on Friday. Investors are expecting to hear what Powell thinks about the state of the U.S. economy and how he might guide the central bank’s exit from the measures it took to rescue the economy from the Covid-19 pandemic.

“Fed chairs have a track record of foreshadowing major policy announcements at Jackson Hole, and some investors think Powell will provide further clues around the timing of a tapering announcement, which could come as soon as the FOMC meeting next month,” Tapas Strickland, director of economics and markets at the National Australia Bank, wrote in a Friday morning note.

Strickland pointed out that an announcement on tapering is “highly likely” to come before the end of the year.

In overnight trade, the three major U.S. indexes finished lower during Thursday’s regular trading session. The Dow snapped a four-day win streak while the S&P 500 and the Nasdaq Composite both broke five-day win streaks.

Finally, it never rains but it pours. The US Gulf coast looks set to get another hurricane. And a category three hurricane at that. Keep a close watch on the oil price.

Tropical Storm Ida forms, could hit US Gulf Coast as major hurricane

By Alex Sosnowski, AccuWeather senior meteorologist

Published Aug. 26, 2021 3:52 PM BST | Updated Aug. 27, 2021 4:09 AM BST

TRopical Storm Ida formed on Thursday afternoon, and AccuWeather forecasters said it was becoming much more likely that parts of the central Gulf Coast would need to prepare for a strike from a major hurricane late Sunday or early Monday.

In anticipation of this, the National Hurricane Center (NHC) issued several watches on Thursday evening. A storm surge watch was hoisted from the Texas/Louisiana to the Alabama/Florida border, with a tropical storm watch from the Mississippi/Alabama to the Alabama/Florida border. Meanwhile, a hurricane watch was in effect from Cameron, Louisiana to the Mississippi/Alabama border. This includes Lake Pontchartrain and New Orleans.

Ida, the ninth-named storm of the 2021 Atlantic season, which meteorologists have been monitoring since early this week when it was a disorganized cluster of showers and thunderstorms, strengthened quickly on Thursday after it was designated Tropical Depression Nine by the NHC just before noon.

As the depression was gathering strength over the Caribbean Sea south of Jamaica on Thursday, hurricane hunters from the United States Air Force were sent to investigate the growing storm, though poor weather briefly caused the mission to be delayed. Tropical storm warnings were issued for the Cayman Islands as well as parts of Cuba.

On Thursday evening, the tropical storm was moving to the northwest at a speed of 12 mph and had maximum sustained winds of 40 mph. It was 65 miles southeast of Grand Cayman Island and 365 miles southeast of the western tip of Cuba

Education Department will cancel student debt for 115,000 borrowers

The U.S. Department of Education announced Thursday it will cancel $1.1 billion in student debt for 115,000 borrowers.

The relief will go to those who attended ITT Technical Institute, a for-profit school that is now defunct. The school is accused of misrepresenting itself and steering students into pricey private loans. These borrowers didn’t finish their degrees and left the school after March 31, 2008.

“Today’s action continues the Department’s efforts to improve and use its targeted loan relief authorities to deliver meaningful help to student borrowers,” U.S. Secretary of Education Miguel Cardona, in a statement.

The Education Department under the Biden administration has now canceled student debt for 563,000 borrowers, totaling $9.5 billion.

Still, President Joe Biden remains under pressure from Democrats, advocates and borrowers to go further and cancel $50,000 per borrower in student debt for all.

Biden has asked the Education Department and the U.S. Department of Justice to review his legal authority to forgive student debt through executive action. The findings of those reports are not yet public.

“You don’t need Congress,” Sen. Majority Leader Chuck Schumer, D-N.Y., has said. “All you need is the flick of a pen.”

Higher food prices loom due to gigantic pay rises for drivers as shortfall swells to 100,000

Thursday 26 August 2021 1:47 pm

Shoppers could face long-term higher prices for food as result of systemic changes to the supply chain, supermarkets chiefs and hauliers warned today.

Bosses at the Road Haulage Association said the “substantial” pay rises offered by firms in need of new drivers could force supermarket bosses to pass the costs on to customers.

Hauliers have warned that there is a shortfall of around 100,000 drivers. This has been driven by thousands of European drivers leaving during the pandemic and not returning, as well as “high numbers” of workers retiring. The average age of an HGV driver in the UK is 55.

Retailers and restaurants chains, including Nando’s and McDonald’s, have been hit by product shortages as meat packers and other manufacturers have also faced significant worker shortages.

The Government introduced a seasonal worker visa scheme in December for 30,000 workers, primarily for the summer fruit picking season, but meat processors were excluded.

Rod McKenzie, managing director of policy and public affairs at the Road Haulage Association, said today that the shortage of drivers needs urgent Government action and firms have offered better incentives and pay deals to secure potential recruits.

“Certainly drivers’ pay is increasing, often by quite substantial amounts,” he said.

“This in turn is a cost that will need to be passed on, and given the tight profit margins of most haulage operators that means their rates to customers will have to go up.

“In turn, this may mean more of us paying higher prices for goods, services and shopping – including food prices – going forward.”

U.K. Carmakers Beset by Shortages in Worst July Since 1956

By Siddharth Vikram Philip

26 August 2021, 00:01 BST Updated on 26 August 2021, 09:15 BST

·         Production plunged 38% from a year ago to lowest in 65 years

U.K. car production plummeted in July to levels last seen 65 years ago as shortages of semiconductors and staff continued to wreak havoc on the auto industry.

Carmakers made only 53,438 vehicles, down 38% from a year ago and the lowest for the month of July since 1956, the Society of Motor Manufacturers and Traders said Thursday. Similar issues plagued auto manufacturers in June, when they had their second-worst showing for that month since 1953.

U.K. car production fell 38% to lowest July total in 65 years

In addition to the chip shortage that has idled assembly lines around the globe, U.K. carmakers struggled with a wave of workers being “pinged” by the National Health Service’s Covid-19 contact-tracing app. This month, the U.K. lifted the requirement for fully vaccinated adults to isolate after coming into contact with an infected person. 

“While the impact of the ‘pingdemic’ will lessen as self-isolation rules change, the worldwide shortage of semiconductors shows little sign of abating,” Mike Hawes, the chief executive officer of SMMT, said in a statement. Hawes called for the government to reduce energy levies and business taxes for the sector.

Supply-chain issues derailed a short-lived run of positive earnings for Jaguar Land Rover owner Tata Motors Ltd., which posted a bigger net loss for the quarter ended in June than any analyst expected. JLR warned last month that deliveries in the current quarter will be about 50% lower than planned.

U.K. carmakers aren’t alone. In Germany, Volkswagen AG’s Wolfsburg plant -- the world’s largest car factory, employing some 60,000 people -- restarted following its usual summer break on only one shift. Audi, the group’s biggest profit contributor, also extended the summer recess at its two factories in the country by a week.

Stellantis NV, Europe’s second-largest automaker, also has extended annual factory downtime at several sites due to the Covid-19 outbreak in Malaysia that is crimping chip supplies further. Plants in Rennes and Sochaux, France, and Eisenach, Germany, are shut this week.

McDonald’s runs out of milkshakes as supply chain woes grip the UK

Published Wed, Aug 25 2021 9:13 AM EDT

LONDON — Supply constraints are weighing on Britain’s economy with several big-name firms announcing they have run out of stock on particular items. 

McDonald’s on Tuesday said it had ran out of milkshakes across the country. The U.S. fast food giant has also been deprived of some bottled beverages throughout its 1,250 British outlets this week. 

Last week, popular chicken chain Nando’s was forced to close around 50 restaurants across Britain due to poultry shortages, while KFC has also been unable to provide some menu items in recent weeks.

The supply chain struggles are being widely attributed to a lack of truck drivers, caused by a confluence of new post-Brexit EU immigration rules, Covid-19 measures and self-isolation guidance. 

Willem Sels, chief investment officer for private banking and wealth management at HSBC, said Monday that while the surge of self-isolation recommendations seen in July appeared to be moderating, there are some signs that the consumer spending boost from reopening the economy is also fading. However, he suggested that the underlying data remains hopeful. 

“Businesses that are facing shortages in either goods or workers often have to react by paying more, increasing cost pressures,” he said.  

---- The Confederation of British Industry revealed on Tuesday that retail inventories fell to their lowest levels on record in August.

The British Poultry Council this week accused the government of overlooking a worker shortage in the sector, particularly in farming and processing jobs. 

---- Meanwhile, lobby groups the British Retail Consortium and Logistics UK have jointly demanded further action to address a driver shortfall of around 90,000. The groups have called for the government to review plans not to grant temporary work visas to drivers from EU countries. 

Gaps in supermarket and grocery store shelves have been observed across the U.K., and some supermarket chains have begun offering bonuses to increase recruitment.

Lisa Shaw: Presenter's death due to complications of Covid vaccine

26 August, 2021

A radio presenter died due to complications from the AstraZeneca Covid-19 vaccine, a coroner has found.

Lisa Shaw, who worked for BBC Radio Newcastle, died at the age of 44 in May after developing headaches a week after getting her first dose of the vaccine.

Newcastle coroner Karen Dilks heard Ms Shaw suffered blood clots in the brain which ultimately led to her death.

The inquest heard the condition linked to the AstraZeneca vaccine was very rare.

The coroner said: "Lisa died due to complications of an AstraZeneca Covid vaccination."

Ms Dilks said Ms Shaw was previously fit and well but concluded that it was "clearly established" that her death was due to a very rare "vaccine-induced thrombotic thrombocytopenia", a condition which leads to swelling and bleeding of the brain.

Ms Shaw, a mother of one from Consett, received her first dose of the vaccine on 29 April.

On 13 May she was taken by ambulance to University Hospital of North Durham after having a headache for several days.

In a statement, Dr John Holmes who treated her said she complained of having a "severe headache shooting and stabbing" across her forehead and behind her eyes.

Tests were carried out and blood clots were found in her brain, prompting her to be moved to the neurology specialist unit at Newcastle's Royal Victoria Infirmary (RVI).

According to the UK medical regulator, there have been 332 reported cases and 58 reported deaths - after nearly 35 million doses of the AstraZeneca vaccine in the UK.

Japan suspends 1.63M doses of Moderna over contamination

TOKYO (AP) — Japan suspended use of about 1.63 million doses of Moderna vaccine Thursday after contamination was found in unused vials, raising concern of a supply shortage as the country tries to accelerate vaccinations amid a COVID-19 surge.

The health ministry said contamination was reported from multiple vaccination sites. Some doses might have been administered, but no adverse health effects have been reported so far, officials said.

Takeda Pharmaceutical Co., a Japanese drugmaker in charge of sales and distribution of the vaccine in Japan, said it decided to suspend use of doses manufactured in the same production line as a safety precaution.

It asked Moderna to conduct an emergency investigation and told medical institutions and organizers to stop using the vaccine produced in Spain and shared the production numbers that may be affected.

The health ministry and Takeda did not give details on the type of contamination or if the doses in question may have been distributed outside Japan.

The Moderna vaccine problem came just as Japan struggles with surging infections, with daily new cases hitting new highs in many parts of the country and severely straining the health care system.

J&J says COVID-19 vaccine booster after 6 months adds 'robust' protection

Aug. 25, 2021 / 9:31 AM

Aug. 25 (UPI) -- Pharma company Johnson & Johnson announced Wednesday that new studies show that people who received its one-shot COVID-19 vaccine can build up more protection against the coronavirus with a booster shot after six months.

The company said the research showed that those who received the booster after six months had significantly more antibodies than they did just a month after they had the first shot.

Johnson & Johnson said the early-stage trials indicated the booster delivered a "rapid and robust" increase in spike-binding antibodies and appears to offer more protection if the effectiveness of the initial shot begins to wane over time.

Earlier this month, the Centers of Disease Control and Prevention recommended that Americans who received the vaccine from Pfizer or Moderna receive a booster eight months after the second dose.

More studies are being done on the existing vaccines to see how they perform over time and whether they offer adequate protection against known variants like the Delta coronavirus strain.

Johnson & Johnson submitted its new data to the journal medRxiv for publication and peer review.

"A booster dose of the Johnson & Johnson COVID-19 vaccine further increases antibody responses among study participants who had previously received our vaccine," Dr. Mathai Mammen, research and development head of Johnson & Johnson subsidiary Janssen, said in a statement.

---- Janssen produces the Johnson & Johnson vaccine, which is the only one of the three authorized in the United States that is adenovirus-based and requires only one dose for full protection. The Pfizer and Moderna vaccines are based on messenger RNA, or mRNA.

The company said in its update on Wednesday that it will work with the CDC, Food and Drug Administration, European Medicines Agency and other health authorities regarding a booster protocol.

The Vaccinated Are Worried and Scientists Don’t Have Answers

By Kristen V Brown and Rebecca Torrence

21 August 2021, 10:00 BST Updated on 22 August 2021, 15:31 BST

·         Anecdotes signal surprising number of infections in vaccinated

·         Officials must formulate plans despite a dearth of hard data

Anecdotes tell us what the data can’t: Vaccinated people appear to be getting the coronavirus at a surprisingly high rate. But exactly how often isn’t clear, nor is it certain how likely they are to spread the virus to others. 

Though it is evident vaccination still provides powerful protection against the virus, there’s growing concern that vaccinated people may be more vulnerable to serious illness than previously thought.

There’s a dearth of scientific studies with concrete answers, leaving public policy makers and corporate executives to formulate plans based on fragmented information. While some are renewing mask mandates or delaying office reopenings, others cite the lack of clarity to justify staying the course. It can all feel like a mess.

“We have to be humble about what we do know and what we don’t know,” said Tom Frieden, a former director of the Centers for Disease Control and Prevention and the head of the nonprofit Resolve to Save Lives. “There are a few things we can say definitively. One is that this is a hard question to address.”

Absent clear public health messaging, vaccinated people are left confused about how to protect themselves. Just how vulnerable they are is a key variable not just for public health officials trying to figure out, say, when booster shots might be needed, but also to inform decisions about whether to roll back reopenings amid a new wave of the virus.

Layered graphene with a twist displays unique quantum confinement in 2-D

Date:  August 23, 2021

Source:  DOE/Brookhaven National Laboratory

Summary:  Bilayer graphene with one of the two layers twisted displayed unique resonant electronic behavior. Understanding how electrons move in such 2-D materials could shed light on how to manipulate them for quantum computing and communication.

Scientists studying two different configurations of bilayer graphene -- the two-dimensional (2-D), atom-thin form of carbon -- have detected electronic and optical interlayer resonances. In these resonant states, electrons bounce back and forth between the two atomic planes in the 2-D interface at the same frequency. By characterizing these states, they found that twisting one of the graphene layers by 30 degrees relative to the other, instead of stacking the layers directly on top of each other, shifts the resonance to a lower energy. From this result, just published in Physical Review Letters, they deduced that the distance between the two layers increased significantly in the twisted configuration, compared to the stacked one. When this distance changes, so do the interlayer interactions, influencing how electrons move in the bilayer system. An understanding of this electron motion could inform the design of future quantum technologies for more powerful computing and more secure communication.

"Today's computer chips are based on our knowledge of how electrons move in semiconductors, specifically silicon," said first and co-corresponding author Zhongwei Dai, a postdoc in the Interface Science and Catalysis Group at the Center for Functional Nanomaterials (CFN) at the U.S. Department of Energy (DOE)'s Brookhaven National Laboratory. "But the physical properties of silicon are reaching a physical limit in terms of how small transistors can be made and how many can fit on a chip. If we can understand how electrons move at the small scale of a few nanometers in the reduced dimensions of 2-D materials, we may be able to unlock another way to utilize electrons for quantum information science."

At a few nanometers, or billionths of a meter, the size of a material system is comparable to that of the wavelength of electrons. When electrons are confined in a space with dimensions of their wavelength, the material's electronic and optical properties change. These quantum confinement effects are the result of quantum mechanical wave-like motion rather than classical mechanical motion, in which electrons move through a material and are scattered by random defects.

For this research, the team selected a simple material model -- graphene -- to investigate quantum confinement effects, applying two different probes: electrons and photons (particles of light). To probe both electronic and optical resonances, they used a special substrate onto which the graphene could be transferred. Co-corresponding author and CFN Interface Science and Catalysis Group scientist Jurek Sadowski had previously designed this substrate for the Quantum Material Press (QPress). The QPress is an automated tool under development in the CFN Materials Synthesis and Characterization Facility for the synthesis, processing, and characterization of layered 2-D materials. Conventionally, scientists exfoliate 2-D material "flakes" from 3-D parent crystals (e.g., graphene from graphite) on a silicon dioxide substrate several hundred nanometers thick. However, this substrate is insulating, and thus electron-based interrogation techniques don't work. So, Sadowski and CFN scientist Chang-Yong Nam and Stony Brook University graduate student Ashwanth Subramanian deposited a conductive layer of titanium oxide only three nanometers thick on the silicon dioxide substrate.
