The FTSE 100 staged an impressive rebound in Tuesday trading, jumping 145 points to 10,396 as investors rushed back into UK equities after a sharp retreat in oil prices. The rally marked one of the strongest early moves for London’s benchmark index in recent sessions, with heavyweight gainers such as Persimmon (LSE: PSN) and International Consolidated Airlines Group (LSE: IAG) leading the charge.
After a volatile start to the week driven by geopolitical fears and a spike in crude, sentiment turned sharply more positive as oil prices cooled. That shift eased pressure on inflation expectations and helped revive appetite for cyclical stocks, especially housebuilders, airlines, banks, and industrial names. While energy majors such as BP and Shell moved lower, the wider market was clearly in risk-on mode.

Why the FTSE 100 moved sharply higher today
The biggest reason behind the FTSE 100 rally was the sudden drop in oil prices. Brent crude, which had surged close to $120 per barrel during peak market panic, pulled back toward the $90 level. That reversal changed the tone across global financial markets almost immediately.
Lower oil prices matter because they reduce concerns around energy-driven inflation, consumer spending pressure, and margin compression for businesses. When crude spikes, investors often fear that transport, manufacturing, and travel companies will face rising costs. But when oil retreats, that pressure starts to fade, making equities look far more attractive.
The rebound was not limited to London. Asian markets also traded firmly higher, and Wall Street had already shown signs of stabilising after an earlier wave of selling. That global recovery helped support the FTSE 100 at the open, with buying accelerating as the session progressed.
Persimmon soars 10% after strong earnings reaction
Persimmon emerged as the top FTSE 100 performer, with the stock surging around 10% after investors welcomed its latest full-year results. The housebuilder reported a 13% rise in annual profit and maintained its dividend at 60p per share, both of which gave the market confidence that trading conditions are improving.
The update also included encouraging commentary on the start of 2026. Management pointed to stronger sales momentum in the opening weeks of the year, even as broader macro uncertainty remains in focus. That was enough to trigger a strong relief rally in the shares, especially after recent weakness linked to geopolitical tensions and broader market risk aversion.
Housebuilding stocks are highly sensitive to interest rate expectations, mortgage affordability, and consumer confidence. So when the market sees stable dividends, improving sales, and less panic around inflation, it tends to reward the sector quickly. Persimmon’s move higher reflected exactly that dynamic.
IAG gains 6% as falling oil boosts airline outlook
IAG, the parent company of British Airways, also climbed strongly, gaining roughly 6% as investors bet that lower fuel prices could support airline profitability. For airline operators, fuel remains one of the largest operating expenses, which means any sharp drop in crude can have a meaningful impact on margins.
The rally in IAG also reflected a broader shift back into travel-related stocks. If oil prices continue to cool and consumer demand remains firm, investors may become more confident that airlines can protect earnings even in a mixed economic environment. That is especially important heading deeper into 2026, when the market will be closely watching leisure demand, ticket pricing, and capacity trends.
Alongside IAG, a range of cyclical FTSE names also pushed higher, including engineers, miners, and financial stocks. That broad participation suggests this was more than just a single-stock reaction. Instead, it looked like a wider reset in market sentiment.
Key numbers behind the FTSE 100 rally
By early trading, the FTSE 100 had climbed to around 10,396, up from the previous close near 10,249. That represents a gain of roughly 1.4% in a short space of time, a notable move for an index typically driven by large-cap defensive and multinational names.
Among the standout movers, Persimmon gained more than 10%, while IAG added close to 6%. On the other side of the market, BP and Shell fell as weakening crude prices hit oil-linked shares. In effect, traders rotated out of defensive energy exposure and back into sectors that benefit more directly from lower input costs and improving risk appetite.
For official market data and wider UK share performance, traders often track the London Stock Exchange. Those following commodity moves can also monitor Brent crude price action, which remains one of the biggest drivers of near-term sector rotation.
Market reaction shows risk appetite is returning
Tuesday’s move suggests investors were willing to look past recent panic and focus on the easing in oil markets. That helped trigger a strong rebound not only in the FTSE 100 but also in sectors that had been under pressure during the earlier sell-off.
Importantly, the rally was driven by a combination of macro relief and stock-specific catalysts. Persimmon had earnings support, IAG had the fuel-price tailwind, and the broader market had a clear sentiment boost from falling crude. When several positive factors line up at once, index-level gains can accelerate quickly, which is exactly what happened here.
Outlook for the FTSE 100 after today’s jump
The big question now is whether the FTSE 100 can hold above the 10,390 area and build on this rebound. Much will depend on whether oil prices remain contained and whether geopolitical headlines continue to cool. If crude stays below recent highs, sectors such as airlines, housebuilders, and consumer-focused names could keep attracting buyers.
At the same time, volatility has not disappeared. A renewed surge in energy prices or another geopolitical shock could quickly bring sellers back into the market. Even so, Tuesday’s rally showed that investors are still willing to buy quality FTSE names aggressively when macro pressure begins to ease.
For now, the message from the market is clear: the FTSE 100 has bounced back hard, and with Persimmon and IAG leading the way, traders are once again rotating toward stocks that can benefit most from calmer oil markets and improving confidence.
