UK Economy Set to Grow Just 0.7% in 2026 as OECD Slashes Forecast
The Organisation for Economic Co-operation and Development has slashed its growth forecast for the United Kingdom economy in 2026 from 1.6 percent to just 0.7 percent, citing the economic consequences of the US-Iran war as the primary driver of the downgrade. The cut of nearly a full percentage point represents one of the most significant revisions to UK economic projections since the immediate aftermath of the Ukraine invasion in 2022.
The OECD’s updated outlook reflects a chain of economic consequences flowing from the conflict: higher oil and gas prices feeding directly into inflation; reduced consumer purchasing power as households devote more income to energy and transport costs; suppressed business investment as confidence deteriorates; and weaker global trade flows resulting from the disruption to shipping through the Strait of Hormuz.
The UK’s forecast of 0.7 percent growth places it among the weaker performers in the OECD’s developed economy grouping, reflecting both the direct energy exposure of the British economy and the particular vulnerability of UK financial markets to geopolitical risk. The revised figure is barely above the technical recession threshold, defined as two consecutive quarters of negative growth, and analysts noted that sequential quarterly performance could be uneven enough to produce a negative quarter or two even within an annual growth total of 0.7 percent.
Chancellor Rachel Reeves was briefed on the OECD projections ahead of publication and issued a statement acknowledging the challenging external environment while pointing to the government’s resilience measures and the domestic investments committed under the comprehensive spending review as factors that should support UK performance relative to the OECD average.
Business organisations expressed concern that the revised forecasts would increase the pressure on already cautious corporate investment plans. The CBI’s most recent business sentiment survey had shown a notable deterioration in investment intentions since the outbreak of the conflict, with executives citing both the direct cost pressures from energy prices and the broader uncertainty about when stability would return to global markets.
