UK budget cuts energy bills, taxes banks, boosts defense

First reported · Updated · 16 sources: Reuters, investingLive, CNBC

What happened

The UK budget cuts household energy costs, raises taxes on banks, and directs billions toward defense, Ukraine and artificial intelligence. Finance minister John Healey delivered a cautious budget aimed at preserving fiscal credibility as the Iran war and rising borrowing costs put pressure on the outlook. Growth forecasts were cut to 1% in 2027 and Healey unveiled a £15 billion fiscal buffer.

What it means for markets

The budget's tax increases on banks and spending restraint may weigh on UK financial stocks, while the defense spending boost could support defense equities. The costliest 5-year debt since 2008 and sterling's drop against the euro and dollar suggest gilt traders remain skeptical, with the BOE rate path in focus. Any sign of fiscal slippage or persistent inflation from the retail price warning could further pressure UK bonds and the pound.
