The FTSE 100 has breached the historic 10,000 point mark for the first time, capping a remarkable year for London's leading share index. Across 2025 the benchmark rose more than a fifth, its strongest annual showing since 2009.
For years, London's stock market carried a reputation as something of a poor relation to the roaring exchanges of New York, quietly overlooked by investors chasing flashier gains elsewhere. So it came as a genuine moment of celebration for the City when its flagship index finally smashed through a barrier that had long seemed just out of reach.
A five figure first
The milestone in question was a truly historic one. According to market data, the FTSE 100, the index that tracks the hundred largest companies listed in London, surged past the symbolic 10,000 point mark for the very first time in its history, doing so on the opening trading day of the new year in a burst of early optimism.
It is worth noting a small caveat to the achievement. As reports made clear, while the index climbed above 10,000 points during the course of trading, it had not yet managed to close the day above that threshold, meaning the barrier was breached within a session rather than confirmed at the final bell, though the significance was hardly diminished.
The best year since 2009

This dramatic milestone did not appear out of nowhere, but rather crowned a genuinely exceptional twelve months. According to the figures, over the course of 2025 the index of Britain's biggest public companies climbed by an impressive 21.5 percent, marking its strongest full year performance since way back in 2009.
That comparison is a telling one, for 2009 was the year the market began clawing its way back from the wreckage of the global financial crisis. The steady ascent through 2025 had already produced earlier milestones of its own, with the index notably closing above the 9,000 point level for the first time during the summer, back in July.
What powered the rally
So what exactly drove the market to these dizzying new heights? According to the analysis, the final push above the milestone was led in large part by a familiar mix of heavyweight sectors, with mining companies alongside aerospace and industrial firms doing much of the heavy lifting in lifting the wider index.
A handful of individual names stood out among the top performers. As reported, companies such as the precious metals miner Fresnillo, the engine maker Rolls-Royce, and the industrial and engineering groups Melrose Industries, Babcock International and BAE Systems featured among the biggest risers, reflecting where investor enthusiasm was most concentrated.
A market long overlooked
For many in the City, the achievement carried a significance that went well beyond the number itself. For a good while, the London market had been widely regarded as cheap and unloved, its steady, dividend paying giants overshadowed by the glamour of fast growing technology stocks listed across the Atlantic in the United States.
A rising index, however, is about far more than bragging rights for traders. Because so many ordinary people hold shares indirectly through their pensions and savings, a stronger FTSE 100 quietly bolsters the long term retirement pots of millions of workers who may never follow the daily twists and turns of the market at all.
Why the change
Several threads appear to have come together to spark this change of fortune. As analysts point out, the relatively modest valuations of many London listed firms made them look like bargains to bargain hunters, while the index's heavy weighting toward traditional industries suddenly chimed with a shift in global investor appetite.
Even amid the cheer, a note of caution is worth sounding. Seasoned observers are quick to remind everyone that round number milestones are largely psychological, and that indices which rise swiftly can just as easily give ground, so a single triumphant session should not be mistaken for a guarantee of plain sailing ahead.
The road ahead
Whether the index can now consolidate above this landmark, rather than merely touching it in passing, will be the question preoccupying traders in the weeks to come. Holding the line above 10,000 points on a lasting basis would send a far more powerful signal of confidence than a fleeting intraday spike ever could.
For now, though, London is allowing itself a rare moment of pride. After years of being written off as sleepy and unfashionable, the capital's venerable share index has reminded the world that it is still very much a force to be reckoned with, and that even the quietest of markets can spring a spectacular surprise.
