Is the Fed Rate cut at risk as Janet Yellen flags inflation from the U.S.-Iran war?

Former U.S. Treasury Secretary Janet Yellen warned this week that escalating conflict between the United States and Iran could complicate Federal Reserve efforts to cut interest rates in 2026, as geopolitical risk feeds through energy markets and inflation expectations.

Summary

• Traders price almost no chance of a Fed rate cut at the March meeting.
• Oil price gains due to Middle East conflict add upward pressure on inflation expectations.
• Yellen’s comments reinforce caution, pushing markets to price “higher for longer.”

According to Bloomberg, Yellen said the trajectory of oil prices and the overall inflation outlook “depends on how long the Iran conflict affects the oil market,” a subtle but clear signal that monetary easing may be delayed.

That caution comes as markets reassess their rate-cut bets for the Fed’s March meeting.

Fed rate cuts look unlikely

CME Group FedWatch data shows traders now assign roughly 97.4% probability that the Federal Reserve keeps rates unchanged (350–375 bps) on March 18, with only a small chance (around 2.6%) of a cut before the end of the month.

The chart highlights how markets have backed away from earlier expectations for near-term easing.

Prediction market traders are echoing traditional rate expectations ahead of the Federal Reserve’s March meeting. On Polymarket, roughly 97% of participants are betting that the Fed will leave rates unchanged, according to a contract titled “Fed decision in March.”

Geopolitical tension in the Middle East has pushed crude oil prices higher, adding an inflationary “risk premium” that could keep headline Consumer Price Index (CPI) prints elevated in the months ahead.

A spike in energy prices typically filters into core inflation components such as transportation, housing and manufactured goods, narrowing the Fed’s window for easing. Global stocks and bond markets have already felt the strain: Asian equities slid, oil and safe-haven U.S. Treasuries rallied, and volatility spiked, reflecting heightened risk aversion.

Yellen’s remarks echo broader concern among central bankers that persistent or renewed inflation pressures, especially from supply-side shocks like energy, make rate cuts less likely in the near term.

Even if domestic inflation returns to trend levels, the lagged effect of oil price shocks could alter the Fed’s “data-dependent” calculus. A prolonged Middle East conflict amplifies this risk, as analysts continue to weigh growth headwinds against inflationary impulses.

Markets now expect the Fed to remain on hold well into 2026 unless inflation cools materially, with geopolitical risk increasingly cited as a key factor in policymakers’ minds.
