FRANKFURT—The European Central Bank said it would raise its key interest rate by 0.75 percentage point, the biggest increase since the early days of Europe’s monetary union, moving aggressively to combat record inflation even as an energy crisis puts Europe on the brink of recession.
The bank said in a statement that it would increase its key rate to 0.75% from zero—its second hike this year following a 50-basis-point rise in July—and signaled that further rises were likely this year.
