I got this from the Chicago Fed:
“The Board of Governors of the Federal Reserve System and the Federal Open Market Committee shall maintain long run growth of the monetary and credit aggregates commensurate with the economy’s long run potential to increase production, so as to promote effectively the goals of maximum employment, stable prices and moderate long-term interest rates.”
I see the dual mandate as regulating the long run growth rate in money supply (1) and availing banks, and thereby the public, of credit (2).
Prudent implementation of the dual mandate ideally should result in full employment, low inflation, and reasonable interest rates.
I am not looking to argue with you on what this means, just to point out what I think the dual mandate is and why. I recognize you may be correct and I may be wrong.
"The Board of Governors of the Federal Reserve System and the Federal Open Market Committee shall maintain long run growth of the monetary and credit aggregates commensurate with the economy’s long run potential to increase production, so as to promote effectively the goals of maximum employment, stable prices, and moderate long-term interest rates."
