The Bank of England (BoE) kept its benchmark interest rate unchanged at 3.75% on Thursday, but delivered a hawkish warning that the escalating conflict with Iran and resulting surge in energy prices could force sharper monetary tightening. The decision came as global oil prices climbed to a four-year high above $122 per barrel, driven by fears of a prolonged blockade of the Strait of Hormuz.
The Monetary Policy Committee (MPC) voted 8-1 to hold rates, with Chief Economist Huw Pill dissenting in favor of an immediate increase to 4.0%. The BoE’s move followed a similar hold by the Federal Reserve and came ahead of an expected pause by the European Central Bank. The central bank abandoned its usual central forecast due to heightened uncertainty, instead outlining three scenarios based on energy prices and second-round effects.
Inflation Scenarios and Policy Response
Under the most severe Scenario C, inflation could peak at 6.2% and stay above the 2% target for three years, assuming persistently high energy prices and strong inflationary spillovers. In this case, the BoE said it would be “likely to warrant a forceful tightening in monetary policy.” Scenarios A and B suggested a less aggressive response, with rising market-based borrowing costs already helping to offset inflation.
BoE Governor Andrew Bailey indicated he placed the most weight on Scenario B, “albeit with slightly reduced second-round effects,” while also assigning “some weight” to Scenario C. Around half of the MPC members who supported holding rates also leaned toward Scenario B. The central bank noted differing views within the committee—some members “might prefer to act early” to prevent inflation from becoming entrenched, while others favor waiting for clearer evidence.
Market and Economic Impact
Before the decision, investors had priced in nearly three quarter-point rate increases for the year. The BoE warned that a prolonged energy shock could fuel “material second-round effects,” including higher wage demands and businesses passing on costs to consumers. At the same time, it pointed to signs of a weakening labor market and said higher borrowing costs in financial markets could help contain inflationary pressures.
Britain is seen as particularly vulnerable to rising energy costs due to heavy reliance on natural gas. Recent data showed firms facing higher input costs and raising price expectations at a record pace. Political uncertainty has also weighed on sentiment, with Prime Minister Keir Starmer facing challenges and controversy surrounding the appointment of Peter Mandelson as ambassador to the United States.
Broader Market Context
London's FTSE 100 rose 0.9% to 10,307.19 points on Thursday, supported by strong corporate earnings and commodity-linked stocks. Mining giant Glencore added 2% after reporting a 19% increase in first-quarter copper production, while engineering and mining stocks led gains. However, the index has underperformed global peers, rising only 1.3% in April, as markets view the UK as particularly exposed to energy price volatility.
