Europe's STOXX banking index fell 4.2%, set for its biggest one-day slide since early June, with declines for most major names including HSBC down 4.5% and Deutsche Bank down 7.9%.
S&P 500's bank index finished down 6.6% on Thursday
after tech-industry lender SVB Financial Group launched
a share sale to shore up its balance sheet due to declining
deposits from startups struggling for funding.
