The US and the global economy are at risk of a severe stag-deflation, a deadly combination of economic stagnation/recession and deflation.

A severe global recession will lead to deflationary pressures. Falling demand will lead to lower inflation as companies cut prices to reduce excess inventory. Slack in labour markets from rising unemployment will control labour costs and wage growth. Further slack in commodity markets as prices fall will lead to sharply lower inflation. Thus inflation in advanced economies will fall towards the 1 per cent level that leads to concerns about deflation.
