UK economy barely grows in the third quarter, missing forecasts ahead of crucial budget

The UK economy grew a weaker-than-expected 0.1% in Q3, down from 0.3% in Q2 and contracting 0.1% in September, primarily due to broad weakness across services, construction, and production, with manufacturing notably impacted by a cyber attack on Jaguar Land Rover. This subdued data precedes the Autumn Budget on November 26, where anticipated tax hikes to address a fiscal deficit could further dampen consumer spending and economic activity. While the Bank of England recently held rates, the weak GDP figures underscore the challenge for policymakers to stimulate growth, with some analysts suggesting a December rate cut remains a possibility, especially if the budget proves contractionary.

Analysis

The U.K. economy recorded a weaker-than-expected 0.1% growth in the third quarter, falling short of Reuters' 0.2% forecast and decelerating from Q2's 0.3% expansion. This subdued performance included a 0.1% month-on-month contraction in September, following a revised flat August, indicating broad-based weakness across services, construction, and production sectors. The Office for National Statistics (ONS) specifically attributed significant manufacturing weakness to a five-week production halt at Jaguar Land Rover due to a cyber attack.

This disappointing economic data precedes the highly anticipated Autumn Budget on November 26, where Finance Minister Rachel Reeves is expected to announce tax hikes to address a fiscal deficit. Analysts, including JPMorgan's Scott Gardner, express concern that these confirmed tax increases could further dampen consumer spending and services activity from Q2 next year, creating additional economic headwinds. The prevailing uncertainty surrounding the budget's impact is causing nervousness among businesses and consumers, as noted by Aviva CEO Amanda Blanc.

The Bank of England recently maintained interest rates, awaiting further inflation and labor market data, yet the weak GDP figures intensify pressure on policymakers. While some economists, like Pantheon Macroeconomics' Rob Wood, still anticipate a December rate cut, particularly if the budget proves contractionary, Wood also suggests that underlying resilient growth, near the UK's 0.3% quarter-on-quarter potential, could limit the emergence of spare capacity, potentially complicating further rate cuts in 2026 despite current expectations for two cuts next year.

Key Decisions for Investors

• Investors should closely monitor the Autumn Budget on November 26 for details on anticipated tax hikes, as these are expected to impact consumer spending and services activity from Q2 next year.
• Given the broad economic weakness and specific manufacturing disruption, consider defensive positioning or re-evaluating exposure to UK consumer discretionary and industrials sectors.
• Watch for the Bank of England's December 18 meeting for potential interest rate adjustments, as a cut could provide some economic stimulus despite fiscal tightening.
