The FTSE 100 Index has traded in a narrow range over the past three months, lagging behind global peers such as the S&P 500, Kospi, and Nikkei 225. This week, three key catalysts are poised to influence the Footsie's direction: political developments in the UK, a weakening British pound, and progress in US-Iran nuclear talks.
Political Uncertainty: Keir Starmer's Exit Plan
Prime Minister Keir Starmer is expected to announce his resignation timeline today, according to reports from The Guardian. Starmer's tenure has been marked by sluggish economic growth and fiscal constraints, limiting his ability to cut taxes without widening the deficit. Instead, he raised taxes, breaking campaign promises and alienating supporters. His appointment of Peter Mandelson as US ambassador, who resigned after being linked to the Epstein files, further eroded public trust. The Labour Party suffered a major defeat in recent local elections, and Starmer is likely to be succeeded by Andy Burnham, who won a parliamentary seat last week. However, investors are concerned that the UK is becoming increasingly ungovernable, with Burnham potentially becoming the seventh prime minister in ten years. This political instability could weigh on the FTSE 100, as it adds uncertainty to fiscal and regulatory policies.
Sterling's Decline: A Double-Edged Sword for the Footsie
The British pound has fallen to 1.3165 against the US dollar, its lowest since March, and nearly 5% below its 2025 peak. The decline stems from a divergence between the Bank of England and the Federal Reserve. The BoE held rates at 3.75% last week, with seven out of nine committee members voting to maintain the status quo, while signaling an unclear path ahead. Meanwhile, the Fed also left rates unchanged but hinted at potential hikes later this year to combat persistent inflation. A weaker sterling has mixed implications for FTSE 100 companies. Export-oriented firms with significant overseas earnings—such as GSK, AstraZeneca, BP, Shell, and miners like Anglo American and Antofagasta—benefit as their USD-denominated revenues translate into higher sterling profits and dividends. Conversely, domestic-focused companies may face headwinds from imported inflation and reduced consumer spending.

US-Iran Nuclear Talks and Oil Price Volatility
US and Iranian officials have begun nuclear negotiations in Switzerland, with a 60-day timeline, and have agreed to maintain the ceasefire in Lebanon. However, Israel's intensified attacks on Lebanon over the weekend threaten to derail the talks. Crude oil prices dropped as traffic resumed through the Strait of Hormuz, despite earlier threats of closure. The situation remains highly volatile, and any escalation could send oil prices higher, impacting the FTSE 100. Companies with exposure to the conflict include International Airlines Group (IAG) and Rolls-Royce, both key players in civil aviation, as well as major banks like Lloyds, Barclays, and HSBC, which have operations in the region.

Investors should monitor these three catalysts closely, as they could drive significant moves in the FTSE 100 this week. The index's performance will depend on the outcome of Starmer's announcement, the pound's trajectory, and developments in the Middle East.
