FTSE Rallies GDP Growth Defies Forecasts

London's benchmark FTSE 100 rallied strongly on Thursday, powered by positive market sentiment following a better-than-expected domestic economic growth reading. The i The FTSE 100 closed around 10,850, adding 1.6% on the session and extending its trailing 12-month gains to over 15%. Broad-based market breadth saw only 24 out of the 100 constituent stocks finishing in negative territory.

Telecommunications, retail, and consumer heavyweights led the top-flight advance. BT Group surged over 4% to lead blue-chip gainers, while AutoTrader Group, British American Tobacco, JD Sports Fashion, and Compass Group all advanced more than 3%. Conversely, technology providers and select miners faced heavy selling pressure: IT services company Computacenter and miner Antofagasta led losses with declines exceeding 6%, while Polar Capital Technology Trust dropped over 5%.

On the domestic macroeconomic front, U.K. GDP expanded by 0.1% month-on-month in August, defying consensus expectations for a 0.1% contraction. Following a robust 0.4% expansion in July, the print puts the U.K. economy on track for a 0.7% quarter-on-quarter expansion in Q3—marking the eighth consecutive rolling three-month increase. Notably, this trajectory significantly outpaces the Bank of England's updated forecast of 0.4% Q/q. Sectoral data revealed industrial production rising 0.8% m/m (driven by a 1.2% jump in manufacturing output), while services output remained unchanged and construction dipped 0.2%.

In global markets, sentiment remained constrained by hotter-than-expected U.S. inflation data. Following Wednesday's elevated CPI figures, U.S. producer price inflation (PPI) spiked to 1.3% year-on-year in September versus 0.5% expected, while core PPI jumped to 0.7% m/m against 0.3% expected. Despite directionless Wall Street futures and mixed European benchmarks, the U.S. dollar retreated, with the Dollar Index losing 0.43% to 102.12. Sterling gained 0.40% to trade at $1.3245 (ranging between $1.3184 and $1.3276), while EUR/GBP edged to 0.8460 and GBP/JPY rose to 209.24. Aligning with a global softening in fixed income yields, U.K. 10-year Gilt yields dropped nearly 10 basis points to close at 5.3339%. Gold surged nearly 2%, crude oil traded directionless, and cryptocurrencies faced sharp downside pressure.

Finish Line: U.K. equities staged a firm rally as resilient August GDP data confirmed the economy's underlying momentum and helped push the benchmark back above the 10,800 mark. While persistent U.S. inflation readings and sharp pullbacks in tech and mining names provided friction, a retreat in sovereign Gilt yields and strong momentum across telecom and retail blue-chips kept the market on solid footing.
