Jamie Dimon's 2026 outlook is mostly upbeat, but he named one thing that could ruin it.
In his April 6 letter to shareholders, the JPMorgan CEO laid out a bullish case for the year while warning investors not to ignore the risk of inflation creeping back. He called it "the skunk at the party," a phrase he does not use lightly.
Dimon told shareholders that inflation "slowly going up, as opposed to slowly going down" could be the story of 2026, which would force rates higher and pull asset prices down with them. "Interest rates are like gravity to almost all asset prices," he wrote.
He pointed to the war between Israel, the U.S., and Iran as the main driver, with the conflict already pushing oil prices up and threatening a supply shock that could match the pandemic. That kind of pressure tends to keep prices high while forcing the Fed to hold rates up for longer.

Dimon was clear that he is not calling for a crash, but he is also not pretending the risk is zero.
His real worry is that high asset prices "create extra risk if anything goes wrong." That matters because household net worth as a share of GDP now sits near 560%, well past the prior peak of around 460% in 2006.
A lot of that wealth is tied to assets that move with rates, which means a Fed rate spike could land harder than usual. Dimon also flagged that foreign investors hold close to $30 trillion in U.S. stocks and bonds, so if they head for the exits, prices can move fast.
JPMorgan finished 2025 with $185.6 billion in revenue and $57 billion in net income, both records.
But Dimon spent more of the letter on what could go wrong, running a worst-case test where rates get cut to the floor, the stock market drops 40%, and credit losses double. Even in that world, JPMorgan still earned a 10% return on tangible equity.
The bottom line: That is the kind of math Dimon wants every investor to do on their own portfolio.
Dimon hedged his warning with three words: "Then again, it may not."
He also said the U.S. economy is now built like a camel that can take more straws than people think, until it can't. The next "straw" he is watching is whether the Fed feels forced to hike again instead of cutting.
