FTSE 100 Best Month Since Iran Attacks: Market Update 2026

The FTSE 100 is on track for its best month since the first US attacks on Iran five months ago, with the index up about 3.5% despite recent volatility. This strong performance highlights resilience in UK equities amid geopolitical tensions and economic uncertainty.

FTSE 100 Performance: A Resilient Rally

The FTSE 100 reached a new record earlier this morning, finishing the month around 10,840 points. After a year low below 9,700 points during the initial Iran conflict, the index has recovered impressively. The broader European Stoxx 600 is up 1.2% this month, recovering from an 8% drop in March.

Key Drivers Behind the FTSE 100's Gains

Several factors have contributed to this positive momentum. Energy stocks have rallied as oil prices spiked, while defensive sectors like healthcare and consumer staples provided stability. Additionally, strong corporate earnings from major constituents have boosted investor confidence.

However, the month-end saw a slight pullback, with the index down 0.5% after 3pm BST, as profit-taking emerged. Despite this, the overall trend remains bullish, supported by expectations of central bank policy easing.

Impact of Iran Attacks on UK Markets

The Iran attacks triggered a sharp sell-off in March, but the market has since recovered. The FTSE 100's ability to rebound underscores its defensive characteristics, with heavy weighting in oil, mining, and pharmaceuticals. This month's gain is the best since the initial attacks, signaling a normalization of risk appetite.

Petrol prices hit a new Iran War high at UK forecourts, adding pressure on households. However, solar power installations recorded the best first half since 2011, showing green energy growth.
