The UK's blue-chip FTSE 100 index closed sharply lower on Thursday, March 5, 2026, shedding 153.71 points, or 1.5%, to finish at 10,413.94. The mid-cap FTSE 250 index also declined, losing 0.9%. The sell-off erased gains from the previous session, when the FTSE 100 had risen 0.8% to close at 10,567.65.
Oil and Inflation Fears Take Center Stage
The primary catalyst for the market's retreat was a significant jump in oil prices, with Brent crude trading near $84.41 per barrel. This surge in energy costs directly fueled concerns about persistent inflation, leading investors to reassess the timeline for potential interest rate cuts from the Bank of England. Rising energy prices often translate into higher sustained borrowing costs, negatively impacting rate-sensitive sectors.
Money markets significantly scaled back their expectations for monetary easing. Traders now price in only one quarter-point rate cut from the Bank of England for the remainder of the year, a reduction from the two cuts anticipated at the end of February. The probability of rates holding steady at the upcoming Monetary Policy Committee meeting is now estimated at approximately 75%. This shift in sentiment exerted immediate pressure on UK housebuilders and consumer discretionary stocks.
Corporate Earnings: A Mixed Picture
Individual stock movements were driven by a flurry of corporate earnings and outlook statements. Pest control giant Rentokil Initial saw its shares climb after reporting a 4% increase in annual adjusted pretax profit. The company noted early signs of stability returning to its North American operations following a period of weakness. In a separate announcement, Rentokil stated that Chair Richard Solomons intends to step down once a successor is appointed.
Insurer Admiral Group also traded higher after announcing record annual profits and a boosted dividend. The company posted a 16% rise in profit before tax from continuing operations, reaching £957.9 million, and increased its dividend per share to 205.0p.
Warnings Weigh on Consumer and Travel Names
On the downside, Reckitt Benckiser shares slipped after the consumer health group warned that softer cold-and-flu demand would weigh on its first-quarter sales. The company described trading conditions in Europe as "challenging," while CEO Kris Licht identified emerging markets as a critical growth area.
The airline sector faced headwinds, with Wizz Air declining sharply. The carrier warned that ongoing turmoil in the Middle East is expected to reduce its annual profit by roughly €50 million. CEO Jozsef Varadi emphasized the company's risk mitigation, stating, "We are not naked," in reference to its existing fuel-cost hedging positions.
Gold miners retreated alongside a dip in the precious metal's price. Defensive stocks showed relative resilience, but their gains were insufficient to offset the broader market decline.
Mid-Cap Movers
Within the FTSE 250, performance was mixed. Thread manufacturer Coats Group jumped after raising its medium-term targets, now forecasting operating margins between 21% and 23% and expecting to generate about $1 billion in free cash flow over five years. CEO David Paja called 2025 a "transformational year" for the business.
Harbour Energy shares advanced after the oil and gas producer unveiled a new shareholder returns policy directly linked to free cash flow, planning to return 45% to 75% annually. Conversely, recruiter PageGroup slid following a reported 67% plunge in annual pre-tax profit to £16.2 million and a halving of its total dividend per share. CEO Nicholas Kirk cited persistent difficulties in converting job interviews into accepted offers as the firm's most significant challenge.
Market Implications and Upcoming Catalysts
The day's trading underscores the market's heightened sensitivity to inflation data and central bank policy. If the oil price rally persists, it risks entrenching inflation concerns and pushing anticipated rate cuts further into the future. This environment typically benefits defensive and energy sectors while pressuring cyclical and interest-rate-sensitive stocks.
Investors are now looking ahead to key data. The U.S. February employment report, due Friday, will be crucial for shaping global interest rate expectations. The Bank of England's next rate decision and meeting minutes are scheduled for March 19, followed by the implementation of the FTSE UK index's quarterly review changes after the close on March 20, effective March 23.
