UK FTSE 100 Falls 2%, Biggest Drop Since May

A 2% single-day drop is notable less for its size than for its rarity in the FTSE 100, an index that has spent much of the year grinding sideways. The absence of an identified driver is itself the story: when a blue-chip benchmark falls this sharply without a clear catalyst, it usually points to broad risk-off positioning or a global macro impulse rather than UK-specific news. Whether this proves a one-day repricing or the start of a deeper de-risking trend is the open question, and the next session's follow-through will be more informative than the move itself.
