UK stocks are poised for gains as optimism returns following easing tensions with Iran. The FTSE 100 index is expected to open higher, reflecting improved sentiment among investors. Market participants are reacting positively to signals that diplomatic efforts may reduce the risk of military escalation in the Middle East. This shift comes after weeks of volatility driven by concerns over potential disruptions to global oil supplies.

Energy stocks are likely to benefit from the improved outlook, with traders betting on lower crude prices if tensions continue to de-escalate. The FTSE 100, which includes major oil and gas companies, has historically been sensitive to geopolitical developments in the region. Investors are also watching for any impact on inflation and interest rate expectations, as oil price fluctuations can influence monetary policy decisions.

The index's performance will be closely watched as a barometer of global risk appetite. A sustained rise in the FTSE 100 could signal broader market confidence, while any reversal might indicate lingering concerns about geopolitical stability. The coming days will be critical in determining whether this optimism translates into sustained gains for UK equities.
