GENEVA — Fears about the world banking system spread to Europe on Wednesday as shares in the globally connected Swiss bank Credit Suisse plunged and dragged down other major European lenders in the wake of bank failures in the United States.
At one point, Credit Suisse shares lost more than a quarter of their value, hitting a record low after the bank’s biggest shareholder — the Saudi National Bank — told news outlets that it would not put more money into the Swiss lender, which was beset by problems long before the U.S. banks collapsed.
