The surge in inflation associated with the Iran conflict has moved beyond a short-term disturbance that many policymakers once expected to ignore. A sequence of central banks - led by the U.S. Federal Reserve - have either increased interest rates or indicated that further tightening may be necessary to bring price growth under control.
Conflict in the Middle East has pushed energy prices higher. Even if an interim peace agreement takes hold, the original article notes, extensive damage to infrastructure and reduced oil inventories mean that the energy sector may not return to normal quickly. That delayed normalisation could stretch into next year, prolonging inflationary pressures.
Those pressures are especially consequential for economies that have yet to restore price stability since the 2021-22 surge in inflation. The article highlights the United States and Britain as notable examples where inflation remains above target, arguing that five consecutive years of above-target inflation increasingly place the credibility of their central banks at risk.
Policy developments
Federal Reserve officials signalled a readiness to act when they announced policy on Wednesday at their first decision under new Chair Kevin Warsh. Investors had entered the year pricing in two or three U.S. rate cuts in 2026; by mid-June those expectations had shifted toward pricing two increases instead, tightening financing conditions in markets even before central banks took new steps.
The Bank of England debated a possible hike at its recent meeting, although it chose to hold rates for the time being. The European Central Bank and the Bank of Japan have already raised interest rates. Norway’s central bank warned that inflation remains too high and said borrowing costs are likely to be increased later in the year.
Market reaction and signalling
The Fed’s tone change was underlined by forward-looking projections that explicitly left a rate increase on the table. "The big picture is that the Fed seems open to raising interest rates," said Stephen Brown at Capital Economics, adding that the Fed’s own inflation forecast would, by itself, point toward a need for hikes.
UniCredit observed that new Fed Chair Warsh’s public language on inflation was unexpectedly hawkish. "Warsh’s inflation rhetoric was more hawkish than we had expected," the bank said in a note. "The FOMC will have little incentive to move while it waits for the committees to deliver their inputs." The Fed also plans to set up several committees to review its operations.
Oil prices and the futures curve
While oil prices have fallen sharply in recent days, the futures curve has flattened. The article reports Brent crude trading around $77 per barrel in the near term, with December futures around $76. That flat curve suggests market participants either doubt the durability of any peace deal or expect that normalisation will be slow because inventories must be rebuilt.
Global spillovers and currency moves
The Fed’s stance tends to reverberate across markets, prompting follow-on effects elsewhere. A steep fall in the Japanese yen on Thursday revived discussions of potential market intervention and increased pressure on the Bank of Japan to consider further rate increases. "The yen’s declines caused by a hawkish-leaning Fed could prod the BOJ to speed up the pace of interest rate hikes," Katsutoshi Inadome, senior strategist at Sumitomo Mitsui Trust Asset Management in Tokyo, said. "We’ve already seen the weak yen push up long-term inflation expectations, a trend that may continue and keep pressure on the BOJ to hike rates," Katsutoshi added.
In the U.K., the Bank of England held rates at its latest meeting but debated the merits of a hike. Markets have nonetheless priced in a BoE move by the end of the year, a view reinforced by the bank’s chief economist’s continued advocacy for tighter policy.
The European Central Bank, which the article notes was the first among major central banks to raise rates in the latest cycle, has kept the door open for further action and cautioned against any assumption that the peace deal will lead to rapid improvement in energy market conditions.
Political backdrop and rate-cut prospects
The report notes that rate cuts once urged by U.S. President Donald Trump now seem unlikely in the near term. New Fed Chair Warsh’s approach - combining hawkish rhetoric on inflation with plans to convene committees to review central bank operations - suggests that the Fed may be cautious about cutting rates while awaiting further internal analysis and advice.
What this means for markets and policy
The combined effect of conflict-driven energy price pressure, central bank hawkishness and shifting market expectations has tightened financial conditions. Those dynamics are feeding into currency volatility, sovereign and corporate borrowing costs, and the outlook for sectors tied to energy and financial markets.
Policy makers face a choice: treat the shock as transitory and keep policy looser, or respond to persistent inflation signals by raising rates and risking slower growth. The article presents evidence that many central banks are leaning toward the latter course as they assess the likely duration and consequences of the current energy shock.
Conclusion
Inflationary pressure linked to the Iran conflict is forcing central banks to re-evaluate the temporary-shock assumption. With energy market normalisation potentially delayed by infrastructure damage and depleted stocks, and with major central banks already inclined toward tighter policy, investors and markets are adjusting to a higher-for-longer interest rate outlook.
