If inflation and unemployment BOTH are very high simultaneously... What is the Fed going to do?

What is in their "toolbox" to address this?  Currently they are using ultra low interest rate and QE to try to address their employment mandate but what if price increases become rampant while unemployment is still up.  Just say full employment mandate be damned and jack up the interest rate?  Or do they keep the loose money flowing and ignore the price stability mandate? What do you think?

If both inflation and unemployment are high, there's not much the Fed can do - the inflation is cost-push rather than demand pull. What this means is that for some reason, commodities used in goods production/service provision are very expensive due to shortages. The Fed can print as much money as it desires, but it will only raise inflation if the money is moving (demand is robust). One of the benefits of easy monetary policy is that it is cheaper to expand company operations and invest - there may be a lag between when inflation rises and unemployment falls, but that supportive monetary policy is one of the reasons why unemployment would eventually fall.
