How the Federal Reserve and Bank of England Are Responding to Inflation Risks from the Iran Conflict

Inflation Context

The Iran conflict triggered a sharp energy price surge starting in March 2026. U.S. headline PCE inflation rose to 4.1% year-over-year by May, up from 2.5% a year earlier . UK CPI stands at 2.8% currently but the BoE forecasts it will rise to 3.2% later this year and stay above the 2% target until early 2028 .

Internal Divisions

Fed: The FOMC has been fracturing since late 2025, with a growing hawkish wing focused on inflation risks and a dovish wing prioritizing labor market support . The July 2026 meeting produced a three-way split — some wanted a 50bp cut, some wanted no change, and some wanted a hike — an unusual degree of discord that Chair Powell has struggled to manage .

BoE: The MPC has been persistently divided throughout 2025–2026. The committee voted 5-4 to cut in August 2025, 7-2 to hold in September 2025, 5-4 to cut again in December 2025, and now 6-3 to hold with three members voting to hike . This shows the hawkish faction has grown as the Iran war's inflationary impact became clearer.

Near-Term Outlook Signals

• Both central banks are on "pause with a tightening bias." The BoE has been more explicit — Governor Bailey stated the Bank is "prepared to take action" if the Iran war's price shock persists . The Fed's statement signals expectations that inflation will ebb despite energy costs, but the three dissents show material uncertainty .

• The next move likely depends on Iran war escalation. If energy prices spike further, both are prepared to raise rates. If the conflict de-escalates and inflation moderates, the door remains open to eventual cuts — but that path has been pushed further out.

• Bond markets are pricing in elevated inflation risk premia in both US Treasuries and UK gilts, consistent with the central banks' hawkish holds. The BoE's MPC vote split (3 wanting a hike) surprised markets, which had expected a 7-2 split, sending the pound and gilt yields higher .

• Upcoming U.S. labor data (August 2026 nonfarm payrolls) will be critical for the Fed. If the labor market remains resilient despite elevated rates, it gives the hawkish faction ammunition to hold firm or even hike. A sharp weakening would strengthen the dovish case for cuts. The FOMC's internal divide means the labor report could tip the balance at the next meeting.

Bottom line: The Iran conflict has frozen both central banks in place. Neither is cutting anytime soon, and both retain a credible threat to hike if energy-driven inflation accelerates further. The next major data point — U.S. jobs data — will help determine whether the Fed's next move is a hawkish hold, a hike, or a resumption of cuts.
