JPMorgan Chase CEO Warns of Interest Rate Shocks from Iran Conflict

Jamie Dimon, CEO of JPMorgan Chase, warned in his annual letter to shareholders that the war in Iran may cause significant ongoing oil and commodity price shocks. These shocks, he said, could result in stickier inflation and higher interest rates than currently expected by markets. The letter was released as part of the bank's annual report.

Dimon attributed rising oil and gas prices to Iran's blockade of the Strait of Hormuz and attacks on regional energy infrastructure. Brent crude oil prices fell below $100 at the start of April but have since risen to $110 as of Tuesday. Higher energy prices contribute to increased costs for borrowing, mortgages, and government debt, while also linking to slower economic growth as businesses and consumers reduce spending.

Nations reliant on imported energy are experiencing effects from these disruptions. Dimon noted impacts on commodity products derived from oil and gas, such as fertilizer and helium. Global supply chains in areas like shipbuilding, food, and farming are also affected.

“Now, because of the war in Iran, we additionally face the potential for significant ongoing oil and commodity price shocks, along with the reshaping of global supply chains, which may lead to stickier inflation and ultimately higher interest rates than markets currently expect.”

The Bank of England voted 9-0 last month to keep interest rates at 3.75%, citing uncertainty from the Middle East war, which began recently. The Monetary Policy Committee is scheduled to meet again on April 30. Money market traders currently anticipate two rate increases this year, down from expectations of four two weeks ago.

Most economists expect the Bank of England to hold rates steady through the first half of 2026, with some forecasting a cut later in the year. The committee faces challenges, as raising rates addresses inflation while cutting them counters economic slowdown and unemployment, both present in the UK.
