FTSE 100 Rises as Oil Slumps, UK Housing Recovery Boosts Sentiment

London stocks advanced on Monday, September 21, 2026, as falling oil prices and signs of a UK housing recovery eased inflation concerns. The FTSE 100 climbed amid hopes for diplomatic progress on the Middle East at this week's UN meeting, which drove crude prices sharply lower. The oil decline reduced near-term inflation pressure, supporting sentiment across energy-sensitive sectors. Meanwhile, data pointing to a recovering UK housing market added to the positive tone. Investors remain focused on this week's UN talks for signals on Middle East tensions and their potential impact on energy markets.
