The deleveraging process that began in 2008 is proving to be long and painful. Historical experience, particularly post–World War II debt reduction episodes, which the McKinsey Global Institute reviewed in a report two years ago, suggested this would be the case.1 And the eurozone’s debt crisis is just the latest demonstration of how toxic the consequences can be when countries have too much debt and too little growth.
We recently took another look forward and back—at the relevant lessons from history about how governments can support economic recovery amid deleveraging and at the signposts business leaders can watch to see where economies are in that process. We reviewed the experience of the United States, the United Kingdom, and Spain in depth, but the signals should be relevant for any country that’s deleveraging.
