Rate outlook Trumps deepening Fed turmoil

U.S. stocks rose on Tuesday as investors looked at President Donald Trump’s controversial efforts to fire Fed Governor Lisa Cook through the prism of possible interest rate cuts soon and parked to one side the longer-term erosion of confidence in the central bank and U.S. policymaking more broadly.

More on that below. In my column today, I ask whether Nvidia’s earnings on Wednesday will be strong enough to dispel concerns among some investors around when AI will deliver its promised returns, and keep the tech rally going.

If you have more time to read, here are a few articles I recommend to help you make sense of what happened in markets today.

Trump’s attempt to fire Fed Governor Lisa Cook for alleged mortgage irregularities has cranked up his feud with the central bank to unprecedented levels. Cook insists she will not resign, her lawyer says she will sue Trump for trying to fire her, and the Fed says she will seek a court ruling to continue in her role.

Traders are betting on a rate cut next month, and Treasury yield curves are steepening. This may offer some near-term support for equities. But beyond that, doubts over the credibility of Fed policy are bound to intensify, and that will surely come back to bite markets.

It’s not just ultra-long U.S. Treasuries that are under heavy selling pressure. Longer-dated yields in Japan, Britain, and the euro zone are also rising as long-term debt sustainability across the industrialized world comes under the microscope.

Britain’s 30-year gilt yield surged on Tuesday to close near its highest level in 27 years, Japan’s 10-year yield rose to a 17-year high, and the 30-year yield hugged Monday’s record high of 3.2150%.

* French politics

France’s minority government is teetering, with the three main opposition parties saying they will not back a confidence vote which Prime Minister Francois Bayrou announced for September 8 over his plans for sweeping budget cuts.

The ripples are being felt across the euro zone, where equity and bond prices fell on Tuesday. Italy has long been viewed as the weak fiscal link among the big euro zone countries, but right now the spotlight is firmly on France.

Can Nvidia results dispel creeping AI doubts?

Questions are arising about when artificial intelligence will deliver its promised returns, meaning tech-concentrated U.S. equity indices sitting near record highs are vulnerable to a correction.

Nvidia’s quarterly results this week could therefore potentially be explosive – not just for the company’s shares or the tech sector, but for all of Wall Street.

The U.S. chipmaker and global AI leader is the world’s most valuable company, with a market cap of $4.4 trillion. That’s double the entire value of Germany’s benchmark DAX and represents 8% of the S&P 500, the largest share for any single stock in the index’s history.

Nvidia is expected to report a 53% increase in revenue to $46.02 billion on Wednesday, according to the mean estimate from 40 analysts, based on LSEG data. That would be higher than the company’s own guidance three months ago.

Given Nvidia’s unprecedented weight in the U.S. market, its earnings releases have become an event – almost akin to U.S. GDP or inflation statistics. But Wednesday’s numbers will be scrutinized particularly closely given the questions being raised about whether we’re seeing an AI bubble.

Doubt appears to be creeping in among investors about when and by how much - or even if - the eye-watering investment in AI projects and infrastructure will begin to pay off. And it’s not just the bearish, contrarian, ‘Magnificent Seven’ short sellers peddling this narrative either.

“Are we in a phase where investors as a whole are overexcited about AI? My opinion is yes,” said none other than ChatGPT founder Sam Altman earlier this month, according to The Verge.

A recent Massachusetts Institute of Technology study found that 95% of companies are getting zero return on the billions of dollars they have plowed into Generative AI investments. More than 80% of companies have looked into or started using tools like ChatGPT and Copilot, but they only boost individual productivity, not firms’ bottom line, the study found.

Investors appear to be growing antsy, with some beginning to rotate out of expensive tech and growth stocks and into small caps and value names. In the last two weeks, the Invesco QQQ exchange-traded fund tracking the tech-heavy Nasdaq 100 is down nearly 1%, while the iShares Russell 2000 ETF is up over 5%.

That could just be a bit of mean reversion in thin August trading, but it’s a nervy backdrop for Nvidia’s earnings release.

One of the key worries being bandied about is the amount of money companies are investing in AI. The ‘Magnificent Seven’ U.S. tech giants have pledged hundreds of billions of dollars in the coming years on AI-related investment.

Morgan Stanley analysts predict nearly $3 trillion of global spending on data centers through 2028, with over $900 billion anticipated in 2028 alone. To put that into perspective, capex spending among all S&P 500-listed companies last year was around $950 billion.
