The FTSE 100 dropped more than 1% on Tuesday, with HSBC Holdings weighing heavily on the index after a disappointing earnings report. The bank’s shares fell over 6% as first-quarter profit missed forecasts due to an unexpected fraud-related charge in the UK, despite strong performance in its wealth and Hong Kong divisions. HSBC said it remains well-positioned to handle global uncertainty, including risks linked to Middle East tensions, and raised its net interest income outlook. Other major stocks also declined, with AstraZeneca down about 1%, Unilever falling 3.2%, and GSK slipping 2.6%. Shell was a bright spot, rising 0.8% on firmer energy prices. Overall sentiment stayed cautious amid US-Iran tensions.
