Recent UK economic data and geopolitical developments have created closely matched trader probabilities across GDP growth ranges for Q2 2026, with 0.0–0.1% at 47.5% implied probability edging out negative growth at 46.5%. Q1 delivered a solid 0.6% QoQ expansion, but this momentum faces headwinds from the Middle East energy shock that began in late February, pushing up inflation expectations and pressuring real household incomes. PMI surveys and labor market softening point to a potential slowdown, while forecasters such as the IMF and OECD have trimmed full-year 2026 GDP projections to around 0.8–0.9%. The narrow spread in market-implied odds reflects uncertainty over whether Q1 strength will carry through or if higher energy costs and tighter financial conditions will dominate the quarter’s outcome.
