The FTSE 100 came under pressure on Thursday after the Bank of England voted unanimously to hold interest rates at 3.75% and signalled that the Iran war could force borrowing cost increases before the end of the year. UK equities fell as investors priced in a more restrictive monetary policy outlook, reflecting concern that higher rates would weigh on corporate earnings and economic growth. The Bank’s hawkish communication caught some market participants off guard and prompted a significant repricing across UK financial assets.
The catalyst for the changed policy outlook is the US-Israel conflict against Iran, which has pushed global energy prices higher and threatened to push UK inflation above 3%. The Bank had previously been expected to reduce rates at this meeting, a move that would have supported equity valuations. Instead, the hold and hawkish signals have created a more challenging environment for UK stocks, particularly those with significant consumer exposure.
Governor Andrew Bailey warned that the energy price shock could spread from petrol to household energy bills if supply disruption continues. He said the Bank was monitoring the situation carefully and retained the option to raise rates if the inflation outlook deteriorated. His careful language attempted to avoid unnecessary alarm while acknowledging the changed economic environment.
UK gilt yields rose and the pound strengthened against the dollar alongside the FTSE 100 fall. City traders moved to price in a June rate hike and a second possible move before December. Analysts noted that the repricing reflected a fundamental shift in the monetary policy outlook that could weigh on UK equities for some months.
For investors in UK equities, the combination of potentially higher rates and rising energy costs creates a more challenging earnings environment. Consumer-facing companies, financial stocks, and housebuilders may face particular pressure if rates rise and household finances deteriorate. The Bank’s next meeting will be closely watched as a guide to whether the hawkish shift of Thursday continues to harden into actual policy action.
