UK Pre-market Briefing — 2026-05-06: Iran War Fallout Hits FTSE, Gilts, and Jet Fuel Costs

Daily Market Briefing — AI synthesis of 30 top stories from the last 24 hours.

• Top theme: The US-Israel war on Iran continues to dominate — FTSE 100 fell 1.4% on Tuesday, jet fuel prices have doubled since the war began with 2 million airline seats cut and ~13,000 fewer flights in May alone, while 80% of Britons polled fear food price rises from the conflict (Opinium survey).
• Second theme: UK gilt markets under pressure — long-term borrowing costs hit a 28-year high amid jitters ahead of Thursday's local and national elections, adding fiscal strain to an already inflation-pressured environment.
• Third theme: UK banking sector in the spotlight — the big four UK lenders posted nearly £14bn in combined Q1 profits, partly fuelled by Middle East-driven market turbulence and high interest rates; the TUC is calling for the bank surcharge to be reinstated from 3% back to 8%.
• Fourth theme: Intertek (FTSE 100) attracted a £10bn-plus cash bid at a fat premium from a Swedish suitor, signalling that M&A appetite persists despite geopolitical headwinds; the FSB separately warned that private credit exposure to AI-driven tech, healthcare, and services sectors could produce 'sizeable' losses if markets correct sharply.
• Fifth theme: Oil prices eased overnight after President Trump raised hopes of a US-Iran agreement to reopen the Strait of Hormuz — any diplomatic breakthrough could sharply reverse energy and aviation sector pressures heading into the next session.
