Dimon Warns Interest Rates May Climb Higher in 2026

JPMorgan CEO Jamie Dimon says interest rates could rise further than markets expect as sticky inflation and the Iran war keep pressure on borrowing costs.

JPMorgan Chase (NYSE: JPM) Chairman and CEO Jamie Dimon warned on Oct. 13 that interest rates could climb higher than investors expect. He pointed to persistent inflation, heavy government borrowing and geopolitical conflict. The warning came alongside third-quarter results in which the bank earned $15.3 billion, or $5.57 per share, compared with $14.4 billion a year earlier. The per-share figure fell short of the roughly $5.90 consensus, a rare miss for the bank.

Managed revenue reached $50.9 billion, up 8% from a year earlier and just under the $51.2 billion expected. Shares rose about 0.8% in early trading.

What Did Dimon Say About Interest Rates?

Dimon said the US economy remains supported by strong business investment and consumer spending, but that several pressures are shifting beneath the surface. He listed "large fiscal deficits, sticky inflation, elevated asset prices, rising interest rates and geopolitical conditions" as the main risks.

He has also cautioned that a move from 5% to 6% would hurt more than a move from 4% to 5%. Borrowers would refinance at higher costs and credit spreads could widen. He stressed that he is not forecasting 6%, only that businesses and investors should prepare for it.

Why Are Rates Rising Now?

Rates are rising because inflation has stayed elevated while demand for capital has grown. Fuel costs have increased and the build-out of AI infrastructure requires heavy financing. Investors are also pricing in larger government debt issuance.

Dimon has linked the war in Iran to continued oil and commodity price shocks and to a reshaping of global supply chains. In his view, both could keep inflation stickier than markets assume.

The central bank has moved in the same direction. The Federal Open Market Committee voted 12-0 on Sept. 16 to lift the target range by a quarter point to 3.75%-4%. Fed Chair Kevin Warsh highlighted inflation risks at the same meeting. The fed rate increase pushed the 10-year Treasury yield back above 5%, where it closed at 5.01%.

How Does the Fed Hike Affect Borrowing Costs?

The hike lifted the prime rate, which banks set at 3 percentage points above the fed funds target. Major lenders raised it to 7.00% from 6.75% effective Sept. 17. The 6.75% level had held since December 2025.

That change feeds directly into credit card, small business and home equity pricing. Updated projections show most officials expecting the benchmark between 4.1% and 4.4% by the end of 2026. That points to the possibility of another increase before year-end.

How Did the Bank's Earnings Reflect the Rate Environment?

Higher rates have so far helped JPMorgan's core lending business. Net interest income rose 13% to $27.1 billion. Management guidance from earlier in the year calls for roughly $105.5 billion in total net interest income for 2026, with about $96.5 billion excluding markets activity.

Segment results were mixed. Consumer and community banking earned $5.7 billion on $21.2 billion of revenue, up 9%. The corporate and investment bank earned $8.2 billion on $22.7 billion of revenue, up 14%. A slowdown in fixed income trading was the main drag behind the earnings miss.

Strategic Context: Peer Banks

Other large lenders reported the same day and sounded similar cautions on rates and inflation.

• Goldman Sachs (GS) earned $5.29 billion, or $17.01 per share, compared with $12.25 a year earlier. Equities trading drove the gain while bond trading slowed. Shares rose 1.9%.
• Citigroup (C) reported profit growth of about 40%, led by investment banking and wealth management. Shares fell 0.7%.
• Wells Fargo (WFC) earned $5.95 billion, or $1.87 per share, ahead of forecasts. Shares fell 1.5%.

What Comes Next for Rates and Markets?

The next test is inflation data and the Federal Reserve's following meeting. If oil prices stay elevated and the 10-year yield holds near 5%, pressure on equity valuations and on floating-rate borrowers is likely to persist. A durable resolution to the Iran conflict or a drop in energy prices would ease that pressure.

For banks, higher rates support interest income but raise credit risk. Dimon's remarks put the trade-off on record: earnings are strong, but the cost of capital for the wider economy is rising.

Outlook

JPMorgan's results show a resilient US economy and a bank profiting from higher rates, with a miss caused by weaker bond trading. Dimon's message is that rates may not have peaked. The Fed has resumed tightening, long-term yields sit at multi-year highs, and sticky inflation and geopolitical shocks remain unresolved. The next several inflation reports and any further Fed action will determine whether the 5% mark on the 10-year becomes a floor or a ceiling.
