Inevitably fragilities remain. Europe is deep in debt and dependent on exports. Japan cannot get inflation to take hold. Wage growth could quickly dent corporate earnings and valuations in America. Emerging economies, which accounted for the bulk of growth in the post-crisis years, have seen better days. The economies of both Brazil and Russia are expected to shrink this year. Poor trade data suggest that Chinese growth may be slowing faster than the government wishes.
If any of these worries causes a downturn the world will be in a rotten position to do much about it. Rarely have so many large economies been so ill-equipped to manage a recession, whatever its provenance, as our “wriggle-room” ranking makes clear…. Rich countries’ average debt-to-GDP ratio has risen by about 50% since 2007. In Britain and Spain debt has more than doubled. Nobody knows where the ceiling is, but governments that want to splurge will have to win over jumpy electorates as well as nervous creditors. Countries with only tenuous access to bond markets, as in the euro zone’s periphery, may be unable to launch a big fiscal stimulus.
