The conflict in Iran has sent shockwaves through global energy markets, with Brent crude prices surging 12% and European natural gas prices climbing 45% since hostilities began. This volatility has forced central banks to reassess their monetary policy trajectories, as higher energy costs threaten to push inflation above target levels.

The Bank of England now faces a dilemma. Previously expected to cut rates in March, policymakers are likely to hold steady as they grapple with uncertain inflation signals from the conflict. Energy price swings make it difficult to gauge the true inflationary impact, complicating the central bank's decision-making process. The BoE's plans for three rate cuts this year are now in jeopardy.

The European Central Bank and Bank of Japan are also recalibrating their approaches. The ECB sees higher risks of inflationary overshoot, while the BoJ's tightening path faces headwinds from Japan's status as a major energy importer. For the Federal Reserve, the US's position as a net energy exporter provides some insulation, though inflationary pressures remain. Central banks worldwide are adopting a wait-and-see approach, with rate decisions increasingly dependent on the conflict's duration and energy market stability.
