In the US, stock casinos, it is Fed day, the decision day in May for the Fed to lower its key interest rate, or not. No change is widely expected.
In better news for the stock casinos, the first trade talks between China and the USA are about to be held this weekend, though no breakthrough is expected, some tariff rollback on each side would be a goodwill start.
European markets head for mixed open as traders
focus on Fed decision
Updated Wed, May 7 2025 12:37 AM EDY
European markets are heading for a mixed
open as traders await the U.S. Federal Reserve’s latest monetary policy
announcement on Wednesday afternoon.
The U.K.’s FTSE 100 index is expected
to open 6 points lower at 8,591, Germany’s DAX up 40 points at 23,276,
France’s CAC 5
points higher at 7,696 and Italy’s FTSE MIB 26 points higher
at 38,018, according to data from IG.
Global investors are gearing up for the
Fed’s interest rate decision at 2 p.m. ET. Fed funds futures trading suggests just a 3.1% chance
of the central bank cutting interest rates this meeting, according to CME’s
FedWatch tool. Traders will nevertheless be listening for Fed Chair Jerome
Powell’s comments after the announcement for insights into the path of rates
and state of the economy.
Meanwhile in Europe, there’s another busy
day of earnings ahead, with Novo
Nordisk, Ørsted, Pandora, Veolia, Legrand, BMW, Siemens Healthineers, Fresenius, Skanska B, JD Wetherspoon, Vonovia, Delhaize and Telecom Italia. Data releases
include European retail sales.
Overnight, U.S.
stock futures advanced Tuesday night after government spokespeople
said U.S. Treasury Secretary Scott Bessent and top trade official Jamieson
Greer would
meet with their Chinese counterparts this week in Switzerland. The
news was taken as a positive sign for developments on trade negotiations after
turbulent market action following President Donald Trump’s tariff announcement
last month.
Meanwhile, Hong
Kong markets jumped over 2% to lead gains in Asia-Pacific after
China’s central bank and financial regulators announced sweeping plans to cut
key interest rates in an effort to shore up growth in the face of trade
worries.

China announces sweeping measures to ease policy
in bid to shore up trade-war hit economy
Published Tue, May 6 2025 9:24 PM EDT
China’s central bank and financial
regulators announced sweeping policy steps Wednesday, including interest rate
cuts, as Beijing ramps up efforts to bolster growth amid mounting trade
worries.
China will cut the seven-day reverse
repurchase rates by 10 basis points to 1.4% from 1.5%, the People’s Bank of
China Governor Pan Gongsheng said at a press briefing. That will bring down the
loan prime rate, the main policy rate, by around 10 basis points, the governor
said.
The central bank will also lower the
reserve requirement ratio, which determines the amount of cash banks must hold
in reserves, by 50 basis points, unleashing additional liquidity of 1000
billion yuan ($138.6 billion) to the market.
The lower policy rates will come in to force Thursday, while the RRR relaxation will be
effective May 15, according to state media Xinhua.
The officials also announced measures to
support financing for several key sectors, including technology and real
estate, along with establishing of a 500-billion-yuan relending tool for
consumption and elderly care.
The PBOC will reduce the mortgage rates
under the nation’s housing provident fund, a government-backed housing lender,
by 25 basis points. Rates on five-year loans for first-time homebuyers will be
trimmed to 2.6% from 2.85%, the governor said.
It will also gradually lower the amount of
cash that auto financing firms must hold in reserves to zero from the current
5%.
These measures, however, may have limited
impact on boosting domestic credit demand, said Tianchen Xu, senior economist
at Economist Intelligence Unit, “borrowing has been somewhat insensitive to
interest rates.”
China is also preparing more measures to
support small and medium enterprises and the private sector, which will be
announced soon, Li Yunze, the head of the financial regulatory administration,
said at the briefing. The government has ramped up efforts in recent weeks
to help
businesses impacted by the tariffs and boost employment.
The broad stimulus announcements Wednesday
showed the officials were acting with greater urgency to bolster the economy
and the easing depreciation pressure on Chinese yuan has created more
desirable condition, analysts said.

Trump officials Bessent and Greer to meet with
Chinese counterparts on trade, economic issues
Published Tue, May 6 2025 6:14 PM EDT
Treasury Secretary Scott
Bessent and U.S. trade representative Jamieson Greer will meet with
their Chinese counterparts
in Switzerland this
weekend to discuss economic and trade matters, their offices announced Tuesday.
“We have shared interests,” Bessent said
later on Fox News’ “Ingraham Angle.” The current tariff war “isn’t
sustainable,” said Bessent, “especially on the Chinese side. And, you know, 145
percent [tariffs], 125 percent, is the equivalent of an embargo. We don’t want
to decouple, what we want is fair trade.”
Bessent and Greer will meet with their
Chinese counterparts on both Saturday and Sunday, the Treasury secretary said.
The meetings appear to be a major step
toward Washington and Beijing beginning negotiations to potentially resolve the
ongoing trade
war ignited by President Donald Trump.
“My sense is that this will be about
de-escalation, not about the big trade deal,” Bessent told host Laura Ingraham.
“But we’ve got to de-escalate, before we can move forward.”
Trump ratcheted up tariffs last
month on Chinese imports to 145% even as he scaled back so-called reciprocal
tariffs on almost all other U.S. trading partners. China,
which is one of America’s largest trading partners, retaliated with steep
tariffs on U.S. goods.
Stock
futures, which opened in the red Tuesday evening, turned sharply higher
immediately following news of the meetings.
Both Bessent and Greer plan to meet with
Swiss President Karin Keller-Sutter during their visit, their offices
said.
The Chinese Foreign Ministry said that
Vice Premier He Lifeng, Beijing’s top official for China-U.S. economic and
trade matters, will meet with Bessent in Switzerland, NBC News reported.

While most every day brings headlines with

Trump, Carney faceoff in Oval Office leaves gaping
differences on tariffs, 51st state
Updated 12:17 AM GMT+1, May 7, 2025
WASHINGTON (AP) — U.S. President Donald
Trump and Canadian Prime Minister Mark Carney faced off in the Oval
Office on Tuesday and showed no signs of retreating from their gaping
differences in an ongoing trade war that has shattered decades of trust between
the two countries.
The two kept it civil, but as for Trump’s
calls to make Canada the 51st state, Carney insisted his nation was “not for
sale” and Trump shot back, “time will tell.”
Asked by a reporter if there was anything
Carney could tell him to lift his tariffs of as much as 25% on Canada, Trump
bluntly said: “No.”
The U.S. president added for emphasis,
“Just the way it is.”
Carney acknowledged that no bit of
rhetoric on tariffs would be enough to sway Trump, saying that “this is a
bigger discussion.”
“There are much bigger forces involved,”
the Canadian leader continued. “And this will take some time and some
discussions. And that’s why we’re here, to have those discussions.”
The meeting between the two leaders
showcased the full spectrum of Trump’s unique mix of aggression, hospitality
and stubbornness.
Shortly before Carney’s arrival, Trump
insulted Canada by posting on social media that the United States didn’t need
“ANYTHING” from its northern neighbor, only to then turn on the charm and
praise Carney’s election win in person before showing his obstinance on matters
of policy substance.

In other news, AI makes mistakes. Oh Canada! Did
President Trump rely on AI for his mistaken “facts” on Canada?
A.I. Is Getting More Powerful, but Its
Hallucinations Are Getting Worse
A new wave of “reasoning” systems from companies
like OpenAI is producing incorrect information more often. Even the companies
don’t know why.
May 5, 2025
Last month, an A.I. bot that handles tech
support for Cursor, an up-and-coming
tool for computer programmers, alerted several customers about a change
in company policy. It said they were no longer allowed to use Cursor on more
than just one computer.
In angry posts to internet
message boards,
the customers complained. Some canceled their Cursor accounts. And some got
even angrier when they realized what had happened: The A.I. bot had announced a
policy change that did not exist.
“We have no such policy. You’re of course
free to use Cursor on multiple machines,” the company’s chief executive and
co-founder, Michael Truell, wrote in a Reddit
post. “Unfortunately, this is an incorrect response from a front-line A.I.
support bot.”
More than two years after the
arrival of ChatGPT,
tech companies, office workers and everyday consumers are using A.I. bots for
an increasingly wide array of tasks. But there is still no
way of ensuring that these systems produce accurate information.
The newest and most powerful technologies
— so-called reasoning
systems from
companies like OpenAI, Google and the Chinese start-up DeepSeek — are
generating more errors, not fewer. As their math skills have notably improved,
their handle on facts has gotten shakier. It is not entirely clear why.
Today’s A.I. bots are based on complex
mathematical systems that
learn their skills by analyzing enormous amounts of digital data. They do not —
and cannot — decide what is true and what is false. Sometimes, they just make
stuff up, a phenomenon some A.I. researchers call hallucinations. On one test,
the hallucination rates of newer A.I. systems were as high as 79 percent.
These systems use mathematical
probabilities to guess the best response, not a strict set of rules defined by
human engineers. So they make a certain number of mistakes. “Despite our best
efforts, they will always hallucinate,” said Amr Awadallah, the chief executive
of Vectara, a start-up that builds A.I. tools for businesses, and a former
Google executive. “That will never go away.”
For several years, this phenomenon has
raised concerns about the reliability of these systems. Though they are useful
in some situations — like writing
term papers,
summarizing office documents and generating
computer code —
their mistakes can cause problems.
The A.I. bots tied to search engines like
Google and Bing sometimes generate search results that are laughably wrong. If
you ask them for a good marathon on the West Coast, they might suggest a race
in Philadelphia. If they tell you the number of households in Illinois, they
might cite a source that does not include that information.

Fact check: Trump makes more false claims about
Canada in advance of meeting with prime minister
Published 6:00 AM EDT, Tue May 6, 2025
President Donald Trump has been making false claims about Canada
for months. He did it again in the days leading up to his scheduled
Tuesday meeting with
Prime Minister Mark Carney.
In an interview that aired
Sunday on NBC, Trump made Canada’s military spending sound much smaller than it
is and made the US trade deficit with Canada sound much bigger than it is. And
in a late-April interview with The
Atlantic, he exaggerated the extent of Canada’s trade reliance on the US.
Here is a fact check of these claims – and
a bunch of others Trump has made about Canada this year.
Canada’s military spending
Trump, who has spoken repeatedly of his
desire to somehow turn
Canada into the 51st US state, said in the NBC
interview: “And by the way, Canada, they spend less money on military than
practically any nation in the world. They pay NATO less than any nation.”
Facts First: It’s not true
that Canada is the lowest military spender in NATO or “practically” the world’s
lowest military spender. Official
NATO estimates show
that, of the 31 alliance members with a standing army, Canada had the
eighth-highest defense spending in absolute terms in 2024; it had the
fifth-lowest defense spending as a percentage of gross domestic product – low,
but not lower “than any nation.” The Stockholm International Peace Research
Institute, which tracks global military spending, reported that Canada
was the world’s 16th-highest 2024 military spender in absolute terms out
of more than 150 countries for which the institute had data.
Trump’s claim is still wrong if he
happened to be speaking literally about members’ direct contributions to NATO’s
organizational budget. Canada is currently the 6th-largest
contributor to
NATO’s “common funding” pool.
The US trade deficit with Canada
Trump has repeatedly said the US has a
“$200 billion” trade deficit with Canada. He used a familiar vaguer formulation
in the NBC interview, claiming, “We subsidize Canada to the tune of $200
billion a year.”
Facts First: Trump’s
claim is not even close to true. Official
US statistics show
the 2024 deficit with Canada in goods and services trade was $35.7 billion.
Even if you only count trade in goods and ignore the services trade at which
the US excels, the deficit was $70.6 billion. And even if he was this time
using the word “subsidize” to describe unspecified other things in addition to
the trade deficit, there is no basis
for the claim.
The US-Canada trade relationship
Trump, talking about Canada, claimed to
The Atlantic that “they do 95% of their business with us.”
Facts First: There’s
no doubt Canada is heavily reliant on its trade relationship with the US, but
Trump’s “95%” figure is a significant exaggeration. Canada’s federal statistics
agency reported in February:
“In 2024, the United States was the destination for 75.9% of Canada’s total
exports, and was the source of 62.2% of Canada’s total imports.”
----Canada and US banks: Trump
falsely claimed in both February and March that Canada
prohibits US banks. While Canada’s tight regulations have discouraged many
foreign banks from opening retail branches there, Canada does not forbid
these banks;
in fact, US banks have been operating in Canada for
well over a century.
The Canadian Bankers Association industry
group said in a February statement that “there
are 16 US-based bank subsidiaries and branches with around C$113 billion in
assets currently operating in Canada” and that “U.S. banks now make up
approximately half of all foreign bank assets in Canada.”

Fed
Faces Tough Choice as Trump Tariffs Risk Stagflation
Tuesday,
May 6, 2025 2:53 AM UTC
The
Federal Reserve is navigating a challenging policy landscape as new tariffs
introduced by President Donald Trump raise the risk of stagflation—slower
economic growth combined with rising inflation. According to The Wall
Street Journal, the Fed now faces a critical decision: delay rate cuts and
risk recession, or act too soon and fuel inflation.
The
tariffs are disrupting global supply chains and increasing import costs,
potentially pushing consumer prices higher. This adds to inflationary pressure
at a time when economic growth is already showing signs of slowing. Fed
officials are expected to keep interest rates unchanged during this week’s
policy meeting as they assess the dual threat to inflation and the labor
market.
Policymakers
are reportedly split. Some favor a cautious wait-and-see approach, citing
lingering inflation risks and uncertainties around business and consumer
responses to the tariffs. Others worry that failing to respond to weakening
economic indicators could lead to a sharper downturn.
The
core dilemma is whether inflation will prove transitory or become entrenched.
The Fed is also mindful of avoiding past mistakes, such as underestimating
inflation following the COVID-19 recovery. For now, the consensus appears to be
in favor of patience, even at the cost of short-term economic pain.
Market
expectations suggest the Fed may wait for more definitive signs of economic
stress before making any policy shift. If inflation expectations among
consumers and businesses remain anchored, the Fed could have more room to
maneuver. However, if those expectations rise, interest rate cuts could be
delayed further, despite weaker growth.
This
delicate balancing act highlights the Fed’s high-stakes role in guiding the
U.S. economy through increasing geopolitical and economic uncertainty.

Global
Shipping Is Grinding to a Standstill. It’s a Matter of Time Until Americans
Feel It.
May
6, 2025
There
aren’t shortages of goods in U.S. stores yet, but if the deterioration in
global shipping is any indication, they are on the way. That could complicate
the White House’s pleas for Americans to be patient as trade officials rush to
strike dozens of deals.
Cargo
has dropped, or is expected to, at major ports including those
of Los Angeles; Long Beach, Calif.; and New York-New Jersey, primarily on
shipments from China, which exports more than any other country to the U.S.
U.S.
import booking volumes have dropped 35% since late March, according to the
shipping data company Vizion, including a 26% drop between the week ended April
21 and the following week. Shipments from China dropped nearly 43% in the last
full week of April, the sharpest decline of the year. During April, several
weeks saw China import bookings down by more than half, Vizion said.
The
potential impact on companies and consumers is broad. Imports of Chinese
electronics, plastics, vehicles, steel, and textiles have all fallen by more
than half.
Perhaps
just as concerning for some farmers and U.S. manufacturers is that export
bookings to China have also collapsed. In the last full week of April, the
number of 20-foot-equivalent containers booked to go to China fell 73% from a
year earlier, the fourth consecutive week with at least a 60% drop, Vizion
said. That is despite U.S. exports staying relatively strong overall.
China’s
major imports from the U.S. include soybeans and other grains, oil and gas, and
semiconductors, among other electronics components.
The
recent export decline is “raising concerns for our agricultural and
manufacturing partners as continued tariffs on exports begin to really take
effect,” said Eugene Seroka, executive director of the Port of Los Angeles, at
a port board meeting at the end of April.
Major
trade routes have been upended by President Donald Trump’s April 2 announcement
of enormous tariffs on imports. Trump suspended most of the “reciprocal”
tariffs for 90 days a week later, but let tariffs against China go into effect,
eventually raising them to 145% for most products. China retaliated with
tariffs of its own.
Now,
trade officials are rushing to strike preliminary agreements with other nations
before the pause is lifted in July.
Americans’
expectation of pain is causing political problems for Trump even though they
haven’t yet resulted in higher prices. About 43.5% of Americans approve of the
job Trump is doing, compared to 51.8% who disapprove, according to a
polling average by
newsletter Strength in Numbers. That gap is about six percentage points wider
than it was when Trump made the tariff announcement.
White
House officials have said that Americans need to “Trust Trump” as he
negotiates with trading partners.
----The
problem for the White House is that shipping activity indicates that pain for
consumers is on the way.
In
addition to reporting falling bookings, shippers have been cutting rates and
capacity on major lines. Capacity between Asia and the U.S. East Coast is down
22% in April and 18% in May from what had previously been scheduled, while
capacity between the Asia and the West Coast is down 20% and 12% in April and
May respectively, according to the maritime research firm Drewry.
“The
shipping lines are trying to balance collapsing Asia-to-U.S. demand with their
capacity both by cancelling dozens of sailings and by ending entire weekly
services,” said Philip Damas, head of Drewry Supply Chain
Advisors, in a company video on Monday.

Mattel
CEO says toy manufacturing won’t come to America, but price hikes will
Published

One
of the goals of President Donald
Trump’s 145% tariffs against China is
to drive manufacturing back to America. But the odds of that are low, at least
when it comes to toys.
“We
don’t see that happening,” Mattel CEO
Ynon Kreiz said on CNBC’s “Squawk
Box” on Tuesday, less than a day after the company withdrew
annual financial targets.
“We
need to remember that a significant part of toy creation happens in America,”
he said. “Design, development, product engineering, brand management all
happens in America. Making product, producing product in other countries,
allows us to create quality products at affordable price points.”
Mattel
has been diversifying its global manufacturing for nearly a decade in an effort
to reduce its dependence on China. By the end of the year, less than 40% of
Mattel’s product will be sourced from the country. Kreiz noted that in two
years, no country will represent more than 25% of Mattel’s sourcing.
In
the meantime, Mattel is taking mitigating actions to fully offset costs
associated with Trump’s trade war with China, including raising prices in the
U.S., while aiming to keep the cost of many toys low.
The
company is expecting to keep between 40% and 50% of its products under $20,
according to Roth analyst Eric Handler.

Trump
orders curb on virus research he blames for Covid pandemic
Tue
6 May 2025 at 12:17 am BST
US
President Donald Trump on Monday ordered new limitations on a form of
biological research his administration says caused the Covid-19 pandemic
through a lab leak in China.
The
United States will halt funding in certain countries for so-called
"gain-of-function" experiments -- aimed at enhancing the properties
of pathogens —- according to an executive order Trump signed Monday at the
White House.
"There's
no laboratory that's immune from leaks -- and this is going to prevent
inadvertent leaks from happening in the future and endangering humanity,"
Health Secretary Robert F. Kennedy Jr. wrote on X.
"Any
nation that engages in this research endangers their own population, as well as
the world, as we saw during the COVID pandemic," added Jay Bhattacharya,
director of the National Institutes of Health.
Trump
has long championed the theory that SARS-CoV-2 leaked from the Wuhan Institute
of Virology as a result of gain-of-function research -- an alternative to the
theory that the virus spilled over naturally from wild animals to humans at a
seafood market in the same city.
The
US government website Covid.gov, which previously focused on promoting vaccine
and testing information, is now devoted to highlighting arguments that favor
the lab leak.
Several
US agencies, including the Federal Bureau of Investigation, the Department of
Energy, and, most recently, the Central Intelligence Agency -- which
shifted its stance under Trump's second term -- now lean toward a lab origin.
Several other intelligence agencies favor natural spillover.
During
the 2010s, the National Institutes of Health funded bat coronavirus research at
the Wuhan Institute via the US-based nonprofit EcoHealth Alliance -- a grant
axed by Trump in 2020 during his first term, but later partially restored under
president Joe Biden.
Complicating
matters, former top infectious disease official Anthony Fauci has maintained
that the work in Wuhan did not meet the federal definition of gain-of-function,
though some virologists and US officials have disputed that claim.
Trump's
order names China as an example of a "country of concern" where such
research should not be supported.

Inverted
perovskite solar cell based on ionic salt achieves 26% efficiency
An international team led by the
U.S. National Renewable Energy Laboratory (NREL) has used ionic salt for the
electron transport layer of a perovskite solar cell to improve device stability
and performance. Test results showed a 26% power conversion efficiency with 2%
degradation after 2,100 hours of 1-sun operation at 65 C.
May
5, 2025
An international team led by the U.S. Department of
Energy’s National Renewable Energy Laboratory (NREL) has applied a new ionic salt at the electron transport layer (ETL)
interface in inverted perovskite solar cells to overcome weaknesses in commonly
used optimized buckminsterfullerene (C60) ETLs.
Inverted perovskite cells have a device structure known
as “p-i-n”, in which
hole-selective contact p is at the bottom of intrinsic perovskite layer i with
electron transport layer n at the top. Conventional halide perovskite cells
have the same structure but reversed – a “n-i-p” layout. In n-i-p
architecture, the solar cell is illuminated through the electron-transport
layer (ETL) side; in the p-i-n structure, it is illuminated through the HTL
surface.
“One big challenge for the conventional device stack is
the weak interface between the perovskite absorber layer and the ETL,” Kai Zhu,
corresponding author of the research, told pv magazine.
To address the issues, the researchers developed an
ionic salt synthesized from C60, referred to in the study as CPMAC. The CPMAC
acronym is short for N-methylglycine, and tert-butyl 4-formylbenzylcarbamate
molecules and hydrochloric acid. It react with C60, to form an ionic salt
called 4-(1′,5′-dihydro-1′-me-thyl-2’H-[5,6] fullereno-C60-Ih-[1,9-c]pyrrol-2′-yl)phenyl-methanaminium
chloride.
“We
are excited that our new CPMAC ionic salt can significantly strengthen this
interface by about a factor of three, and it does not negatively affect device
operation,” said Zhu.
In the study, the researchers used the CPMAC salt as
the “electron shuttle” in inverted perovskite solar cells (PSC) and
minimodules. “This ionic salt layer fundamentally addressed the
disadvantages of molecular C60 layer,” said the researchers.
Test results for the unencapsulated perovskite solar
cell with CPMAC exhibited a 26% power conversion efficiency (PCE) with 2%
degradation after 2,100 hours under standard 1-sun operation at 65 C. The PSC
had a 25.5% efficiency with about 5% degradation after 1,500 hours of operation
at 85 C.
Mini-modules measuring 6 cm2 achieved a PCE of 23% with
less than 9% degradation after 2,200 hours of operation at 55C, according to
the research.
