The US current account deficit approaches one trillion dollars, absorbing 75 percent of world surpluses. A fire sale of US debt could cause a global recession through disorderly devaluation of the dollar, rising interest rates and crashing stock markets. The G7 doctrine of shared responsibility intends to coordinate regional efforts and reforms. The US would increase savings and sell more goods abroad. Europe would increase domestic demand and reform labor and product markets. Japan would revalue the yen and increase productivity. The US, Europe and Japan should reduce their fiscal deficits to pay for future social costs of ageing. China and emerging Asia would revalue their currencies, buying more domestic products. Oil producing countries would invest more at home. There is meagre political capital in most regions for these reforms. The devaluation of the dollar could be faster than G7 policy coordination. This volume analyzes the main issues and individual regions.
