The evidence strongly supports the statement. A CNBC article from October 2023 (Source 13) quotes Chairman Powell acknowledging that 'inflation is still too high' and stating the central bank would be 'resolute' in its commitment to its inflation target. The word 'resolute' is a firm commitment, akin to a vow. This is corroborated by multiple other sources confirming the Federal Reserve's primary mandate is to control inflation and detailing actions taken under Powell's leadership to do so.
