FTSE 100 Gains on U.S.-Iran Diplomatic Hopes and Strong Corporate Earnings

London's blue-chip FTSE 100 index gained on Tuesday, rising 0.55% as of 07:31 GMT, as markets responded positively to tentative signs of diplomatic talks between the United States and Iran, which helped ease immediate geopolitical concerns.

Geopolitical Tensions and Market Sentiment

Investor sentiment was lifted by comments from U.S. President Donald Trump, who told reporters on Monday that the Strait of Hormuz could reopen as part of a phased diplomatic process with Iran. However, Iran’s Foreign Ministry spokesman, Esmail Baghaei, denied that any formal negotiations were underway, stating that a new maritime arrangement with Oman was a technical safety measure.

The broader regional outlook remains complex. Israeli Prime Minister Benjamin Netanyahu publicly stated disagreements with the U.S. over a Gaza transition framework, according to Al Jazeera, underscoring the delicate nature of Middle East diplomacy.

• HSBC (HSBA): The bank reported better-than-expected first-half profit, raised its net interest income guidance, and announced a new share buyback of up to $1 billion.
• Segro (SGRO): The logistics property firm agreed to a £14.3 billion takeover by U.S.-based Prologis, a deal that would create a combined entity valued at approximately $138 billion.
• Smith+Nephew (SN): In contrast, the medical device maker cut its full-year revenue growth forecast, citing persistent weakness in its U.S. orthopaedics division.

European Markets and Commodities

The positive sentiment was reflected across Europe, with Germany’s DAX index adding 0.81% and France’s CAC 40 rising 0.43%. In commodity markets, the improved risk appetite and geopolitical situation pushed oil prices higher, with Brent crude rising 1.4% to $84.94 a barrel. In currency markets, the British pound was little changed against the dollar, trading at $1.3436.
