U.S. stock index futures climbed on Thursday after the Federal Reserve announced a faster wind-down of its pandemic-era stimulus, calming some nerves around surging price pressures.

The U.S. central bank said on Wednesday it would end its bond purchases in March and signaled three quarter-percentage-point interest rate hikes by the end of 2022.
