UK Stocks Slip Amid Inflation Fears and Mideast Conflict

London's FTSE 100 index saw a marginal decrease on Friday, projecting a third straight week of losses. This downturn was primarily driven by escalating Middle East tensions and a surge in oil prices, which amplified inflation anxieties and solidified predictions of an interest rate hike by the Bank of England.

The mid-cap FTSE 250 index, however, registered a slight increase. Market sentiment remained volatile, with both major indexes fluctuating throughout the session.

Despite international efforts to ensure safe passage through the Strait of Hormuz and U.S. moves to increase oil supply, oil prices continued their upward trend. Consequently, UK energy stocks, though near record highs, saw a minor dip. Heavyweight pharmaceutical stocks also experienced a decline.

The Bank of England maintained its interest rate at 3.75% during its recent policy meeting. However, its commentary on inflation posing a greater threat than economic slowdown led traders to price in a significant probability of a 25-basis-point rate increase by April, with further hikes anticipated by year-end.

Fresh fiscal concerns emerged as Britain's February borrowing significantly exceeded forecasts, partly due to volatile debt interest payments. The ongoing conflict in Iran exacerbated funding costs and fueled demands for increased public spending.

In individual stock news, Unilever's shares advanced following confirmation of talks to sell its food business. Conversely, Smiths Group experienced a substantial drop after missing revenue forecasts. Pub chain JD Wetherspoon also saw its stock plummet after forecasting lower-than-expected full-year profits due to rising energy costs and wage taxes.
