JPMorgan CEO Warns Trump's Iran War Could Trigger Stagflation and Economic Crisis

JPMorgan Chase CEO Jamie Dimon delivered a stark warning to shareholders on Monday: Donald Trump's war in Iran could derail the economy and send inflation spiraling upward just as Americans hoped for relief.

In his annual letter accompanying JPMorgan's 2025 report, Dimon said the conflict threatens "significant ongoing oil and commodity price shocks" along with supply chain disruptions that could keep inflation stubbornly high and force interest rates higher than markets currently expect.

Translation: Trump started a war that could make your mortgage more expensive, your grocery bill higher, and your retirement account worth less.

From Economic Recovery to War-Driven Crisis

Dimon warned that geopolitical risks now pose the greatest threat to financial markets and the broader economy. The Iran war and Russia's ongoing invasion of Ukraine are "having an impact on countries and economies across the globe that are not directly involved in war," he wrote.

Countries dependent on imported energy are already feeling the pain. But it goes beyond fuel prices. Dimon pointed to disruptions in fertilizer, helium, shipbuilding, and food production as byproducts of oil and gas shortages ripple through complex global supply chains.

The Federal Reserve has been working to bring inflation down to its 2% target. Persistent inflation above that level, or worse, rising inflation, could force the central bank to raise interest rates to cool price growth. That would make borrowing more expensive for everything from homes to cars to business expansion.

The Stagflation Scenario

Dimon laid out multiple economic scenarios, including the nightmare outcome economists call stagflation: a recession combined with rising inflation. In that scenario, "inflationary forces overcome deflationary ones," leaving Americans with both job losses and higher prices.

"The skunk at the garden party, and it could happen in 2026, would be inflation slowly going up, as opposed to slowly going down," Dimon wrote. "This alone could cause interest rates to rise and asset prices to drop."

He compared interest rates to gravity for asset prices. When rates rise, stocks, bonds, and real estate values tend to fall. That wealth destruction can trigger panic selling and a "flight to cash" as investors scramble for safety.

The mortgage market is already showing strain. Rates have climbed as Iran war-driven inflation fears rattle housing affordability. Federal Reserve officials, including New York Fed President John Williams, have warned that oil price spikes could ripple through the entire economy.

Trump's War, America's Bill

Dimon acknowledged it is "too early to tell how the Iran war will play out" but said the Iranian regime has "fomented terrorism around the world while also violently repressing its own populace."

What he did not say: this war was a choice. Trump escalated tensions with Iran through diplomatic sabotage, crushing sanctions, and military brinkmanship. The administration withdrew from the Iran nuclear deal, assassinated Iranian military leaders, and used the threat of foreign conflict to distract from domestic scandals and consolidate executive power.

Now Americans may pay the price through higher costs at the pump, the grocery store, and the mortgage lender.

Dimon warned that "nuclear proliferation remains the gravest threat to the future of mankind" if Iran ever acquires nuclear weapons. But Trump's abandonment of the diplomatic framework designed to prevent exactly that outcome made war more likely, not less.

Global Supply Chains in Chaos

The Iran war has disrupted oil flows through the Strait of Hormuz, a critical chokepoint for tankers transiting the Persian Gulf. That disruption affects global energy markets even for countries not directly involved in the conflict.

Dimon said a "bad confluence of events" could trigger recession, high credit losses, market volatility, falling asset prices, and rising unemployment. Different regions would experience those effects differently, but no major economy would escape unscathed.

Goldman Sachs has also warned that the Iran war could push inflation higher this year, complicating the Federal Reserve's efforts to manage price stability without triggering a recession.

Accountability for Economic Fallout

Dimon's letter underscores a reality the Trump administration refuses to acknowledge: wars have economic consequences. Launching military conflicts without clear objectives or exit strategies does not just cost lives. It costs jobs, savings, and economic security for millions of Americans who had nothing to do with the decision to go to war.

Trump sold himself as a dealmaker who would keep America out of foreign entanglements. Instead, he manufactured a crisis with Iran that now threatens to destabilize global markets and push the U.S. economy toward stagflation.

Jamie Dimon runs the largest bank in America. When he warns that Trump's war could cause inflation to rise instead of fall, interest rates to spike, and asset prices to collapse, it is worth paying attention.

Because while Trump and his inner circle are insulated from economic pain, the rest of us are not.
