UK 100 Gains 0.46% to 10,373 on Resilient Q1 GDP; Banks Lead Quant Ratings

The UK 100 index rose 0.46% to 10,372.83, buoyed by preliminary Q1 GDP growth of 0.6% q/q—the strongest since Q1 2025—and 1.1% y/y, with March monthly GDP surging 0.3% m/m versus -0.2% expected. This followed a sharp housing sentiment drop on May 13, as RICS house price balance fell to -34 amid Iran war fallout and BoE rate hike bets. Services drove gains (+0.8% q/q), prior quarter revised to +0.2%, and UK led G7 growth, favoring banks like HSBC (Quant 4.86) despite housing and geopolitical risks.
