Several members of the Federal Reserve worried at their most recent meeting that the central bank risks losing credibility if it fails to raise interest rates in the coming months, an account of the meeting published Wednesday shows.

Minutes from the Fed’s Sept. 20-21 meeting said that “several” participants raised the concern that the Fed “risked eroding its credibility” if it continued to delay rate hikes, given that many of the criteria they have set out in the past for raising rates have been met.
