If there is no longer a Phillips curve or a long-term link between money supply and goods and services prices, monetary policy has no effect on inflation
The Federal Reserve, the ECB and the Bank of England are now saying, with varying degrees of intensity, that they want to fight inflation. The financial markets are therefore revising their interest rate expectations upwards. But the central banks' choice may seem curious, since: If there is no longer a Phillips curve (a link between unemployment and inflation); If there is no longer any long-term link between the money supply and goods and services prices; then monetary policy no longer has any effect on inflation. So what is the point of raising interest rates? It may then be better to reverse the use of monetary and fiscal policy, and to fight inflation by reducing fiscal deficits.
