Was it only at the new year that the fanfare was heard for the FTSE 100 index breaking through 10,000 for the first time? It was – on 2 January – and the index then added another 900 points by the end of February. On Thursday, the Footsie briefly fell below that round number as Iran struck Qatar’s enormous Ras Laffan complex, which normally supplies a fifth of the world’s liquefied natural gas, before closing at 10,063, down 2.3% on the day.
There are two ways to view that price action. One is to say the sharp reversal from the peak represents a necessarily severe reaction to the war on Iran. Another is to conclude that a flat year-to-date return, after a bountiful 20% gain in 2025, suggests stock markets have barely begun to take seriously the inflationary impact if the war lasts many more weeks, or even months, and keeps oil above $100 a barrel.
