Why does Jamie Dimon believe a US stock market correction is coming?

JPMorgan Chase CEO Jamie Dimon has warned that US stock markets could face a “significant correction” within the next six months to two years, citing a combination of overheated valuations and mounting global risks.

In an interview with the BBC during his visit to Bournemouth, where he announced a £350 million investment in JPMorgan’s local campus and £3.5 million in philanthropic funding for community initiatives, Dimon said he saw “a lot of things out there” creating uncertainty in financial markets.

“I am far more worried about that than others,” he said, referring to the likelihood of a correction.

“All these things cause a lot of issues that we don’t know how to answer,” he added, pointing to rising fiscal spending, geopolitical tensions, and the remilitarisation of major powers.

"So I say the level of uncertainty should be higher in most people's minds than what I would call normal."

'AI will pay off but some of the investment would probably be lost'

Dimon’s remarks come amid growing debate over whether artificial intelligence-driven gains have pushed equity valuations to unsustainable levels.

Much of the recent rally in US stocks has been fueled by enthusiasm around AI-related companies.

On Wednesday, the Bank of England drew a comparison with the dot-com boom and subsequent bust of the late 1990s, warning that AI valuations “appear stretched” and could face a “sharp correction.”

Dimon acknowledged the transformative potential of AI but cautioned that many investors would likely suffer losses along the way.

“The way I look at it is AI is real, AI in total will pay off,” he said.

“Just like cars in total paid off, and TVs in total paid off, but most people involved in them didn’t do well.”

He added that some of the capital currently flowing into AI “would probably be lost.”

'Should be stockpiling bullets and guns instead of crypto'

Global security has also emerged as a growing concern for the JPMorgan chief.

Earlier this year, he warned in his annual letter to shareholders that the US could exhaust its missile supplies within a week of a potential conflict in the South China Sea.

Reflecting on the broader risks, Dimon emphasized the need for stronger defense preparedness.

“People talk about stockpiling things like crypto, I always say we should be stockpiling bullets, guns and bombs,” he said.

“The world's a much more dangerous place, and I'd rather have safety than not.”

On Fed independence and political pressures

Dimon also weighed in on concerns about the independence of the Federal Reserve, which has faced political pressure from President Donald Trump, who has called Fed Chair Jerome Powell a “moron” and a “numbskull” for not cutting rates faster.

Dimon defended the importance of central bank independence, saying he was willing to take Trump “at his word” that he would not interfere in monetary policy.

He acknowledged that the US had become “a little less reliable” in recent years but credited some of the Trump administration’s actions for encouraging Europe to address its underinvestment in NATO and economic competitiveness.

On US-India trade prospects

Dimon also hinted at positive momentum in US-India trade talks, suggesting that a deal was close to reducing additional tariffs imposed on India for its continued oil trade with Russia.

“In fact, I've spoken to several of the Trump officials who say they want to do that, and I've been told that they are going to do that,” he said.

The veteran banker, often cited as a potential political figure, dismissed speculation about a move into public office.

While billionaire investor Bill Ackman once called him an “incredible choice” for US Treasury Secretary, Dimon said such a role was “not on the cards.”

“If you gave me the presidency, I'd take it,” he joked. “I think I'd do a good job.”
