Jamie Dimon’s Annual Letter Frames the Iran War as ‘the Skunk at the Party’ for the US Economy

JPMorgan Chase CEO Jamie Dimon delivered his 2026 annual letter to shareholders on Monday with the kind of tonal weight that suggests a man who has been thinking carefully about how to say something very serious without triggering panic.

The 48-page document spans everything from artificial intelligence to geopolitical realignment, but the structural heart of the letter is a warning about what Dimon describes as the potential “skunk at the party” — gradually rising inflation driven by the war in Iran, the energy shock it has produced, and the consequences that could follow for interest rates and asset prices across the board.

The imagery is deliberately domestic. A skunk at a party doesn’t destroy it immediately — it just makes it unpleasant enough that everyone eventually leaves. What Dimon is describing is a scenario in which inflation doesn’t spike catastrophically but drifts higher, persistently, in a way that forces the Federal Reserve to keep rates elevated or even raise them, which in turn puts downward pressure on stock valuations and household borrowing capacity.

“The skunk at the party — and it could happen in 2026 — would be inflation slowly going up, as opposed to slowly going down,” he wrote. “This alone could cause interest rates to rise and asset prices to drop. Interest rates are like gravity to almost all asset prices.”

Dimon’s analysis of the war’s economic mechanism is grounded in historical precedent. He invokes the recessions of 1974 and 1982 — both driven partly by oil price surges — while noting that the US economy in 2026 is more energy-efficient than in those earlier decades.

The qualification matters: the US now produces 13.6 million barrels of oil per day domestically, which provides a buffer that didn’t exist in the 1970s. But the Strait of Hormuz closure is disrupting not just oil but natural gas, fertiliser supplies and agricultural commodity prices — a broader supply-chain impact that Dimon compares to the pandemic in terms of structural disruption to global trade flows.

The letter also carries a candid assessment of stagflation risk that many analysts are reluctant to articulate publicly. “There are some scenarios that would result in a recession, which generally reduces inflation, and other scenarios that would lead to a recession with inflation — stagflation — where inflationary forces overcome deflationary ones,” he wrote.

JPMorgan’s own economists have already revised their US recession probability upward to 30% under a prolonged conflict scenario and pushed their year-end PCE inflation forecast to 3.1%.

Alongside the war risk, Dimon raised concerns about private credit markets that have been underappreciated in the broader market discussion. He said losses in leveraged lending and private credit funds are already “a little higher than they should be, relative to the environment,” and warned that weak credit standards during the low-rate period have created vulnerabilities that will become more visible if rate expectations remain elevated. The structural problem, as he sees it, runs deeper than credit quality alone and is compounded by liquidity assumptions that may prove incorrect under stress.

On artificial intelligence, Dimon struck a note of authentic conviction while acknowledging the uncertainty that surrounds the technology’s longer-term effects. “Investment in AI is not a speculative bubble; rather, it will deliver significant benefits,” he wrote, noting that JPMorgan’s technology budget has approached $20 billion in preparation for the transition. The bank is among the most advanced large financial institutions in deploying AI across its operations, and Dimon frames this investment as essential rather than optional. He was honest, however, that “we cannot predict the ultimate winners and losers in AI-related industries” and warned of “second and third-order effects” that may be as disruptive as the internet’s reshaping of social behaviour was to media and retail.

JPMorgan posted $57 billion in net income in 2025, marginally lower than the previous year. Dimon was careful to separate the bank’s resilience from any suggestion of immunity to the broader risks he was cataloguing. “We cannot confidently predict the outcome of current events,” he wrote, “and our company is not immune to their ultimate effects.”
