In "economics" If aggregate supply falls but aggregate demand remains unchanged, there is upward pressure on prices and inflation.
As soon as you put enough pressure on buying demand falls and you curb inflation. The only tool the reserve has , is to raise rates.
Off subject a little, but IMO we will have inflation for the next several years because of companies scrambling to leave China. Demand will remain in the US, but until the supply chains are re-established elsewhere then a little inflation will be the norm.
My opinion anyway.
