Earlier quoted context omitted.
The Federal Reserve manages both the money supply and unemployment, generally against GDP growth targets. Real estate --- residential, commercial, and industrial --- is among the largest asset classes in the financial system, and it acts as collateral and backing of loans and other financial instruments. Those in turn affect banks and their own ability to generate loans, themselves much of the total money supply. Whe…
Propping up assets isn’t in their mandate though.
By definition, solvency and liquidity at the country level depend on major asset classes maintaining some amount of value.
That baseline changes based on regulations of what can or cannot be used as collateral for different measures, what ratios institutions have to maintain, etc, but there is a floor of some sort at which point the financial system implodes and the economy collapses.
Given their powers and mandate, preventing economic collapse is of the utmost importance.
