Recent monthly GDP estimates have driven trader positioning toward the 0.6–0.9% range for UK Q3 2026 QoQ growth, with the 0.7% three-month average through August exceeding consensus amid services-led resilience. Stronger-than-expected July and August outturns, supported by professional services and wholesale activity, have offset construction weakness and production contraction, while energy price pressures from geopolitical factors and rising CPI have tempered broader optimism. The Bank of England’s 3.75% policy rate and OBR’s 1.2% full-year 2026 forecast provide context for modest expansion expectations. Key near-term catalysts include the September monthly release on November 12 and the full quarterly national accounts on December 22, which could shift implied probabilities if September output deviates from flat assumptions.
