London's FTSE 100 index climbed 0.2% to 10,894.67 points on Wednesday, driven by strength in the mining and energy sectors.
The gains in commodity-linked stocks helped offset broader market caution as investors assessed the outlook for global growth and monetary policy.
The rally in miners and energy names reflects ongoing repricing of supply risks and commodity demand, providing a lift to the benchmark index.
This sector-specific strength contrasts with the marginal gains seen in other parts of the market, highlighting the continued influence of energy and industrial metals on London's blue-chip performance.
Investor attention is now fixed on upcoming interest rate decisions from the Federal Reserve and the Bank of England.
The central banks' policy moves are expected to shape market sentiment in the coming weeks, with traders closely monitoring signals on inflation and economic growth.
