Bank of England Holds Interest Rate Steady Amid Economic Uncertainty Over Iran War

The Bank of England's Monetary Policy Committee voted unanimously to maintain its base rate at 3.75% on March 18, as the ongoing Iran conflict clouded the economic outlook with rising energy prices and inflation uncertainty. The decision reversed expectations from just weeks earlier, when markets had widely anticipated a rate cut to support slowing UK economic growth.

The BoE sharply revised its inflation forecasts upward, now expecting CPI to reach 3% in Q2 2026 (up from 2.1% previously forecast) and 3.5% in Q3 2026 (up from 2%). The ECB also flagged that the Iran war was having a 'material impact' on eurozone inflation expectations. MPC member Swati Dhingra said the economy was at a 'crossroads,' while Catherine Mann shifted from considering cuts to signaling a potential rate hike to combat inflation persistence.

The hold positions the BoE alongside the Federal Reserve in a wait-and-see stance, as central banks globally assess the inflationary impact of spiking oil and gas prices from the Middle East conflict. For investors in UK-exposed equities and gilts, the path of rates now depends heavily on geopolitical developments rather than domestic economic fundamentals — a shift that introduces elevated uncertainty into asset allocation decisions for the months ahead.
