The FTSE 100 is down today primarily due to significant declines in major UK banks and oil majors. This drop is part of a broader global selloff in financial stocks triggered by fears about the health of U.S. regional banks. Two U.S. regional banks recently disclosed issues with bad and potentially fraudulent loans, spooking investors and causing a sharp sell-off in banking shares worldwide, including prominent FTSE lenders like Barclays and Standard Chartered which fell over 5%. Additionally, falling oil prices have impacted energy stocks, further weighing on the index. The combination of banking sector concerns and energy price drops has pulled the FTSE 100 down to a two- week low, with the index down about 1.3% today. This selloff also occurs amid cautious investor sentiment linked to wider financial stability risks and ongoing geopolitical tensions. Despite UK economic growth data and positive outlooks from some firms like Pearson, the pervasive uncertainty in the financial sector dominates market sentiment today.
