The worst thing for the world economy would be to assume the worst is over
THE rays are diffuse, but the specks of light are unmistakable. Share prices are up sharply. Even after slipping early this week, two-thirds of the 42 stockmarkets that The Economist tracks have risen in the past six weeks by more than 20%. Different economic indicators from different parts of the world have brightened. China’s economy is picking up. The slump in global manufacturing seems to be easing. Property markets in America and Britain are showing signs of life, as mortgage rates fall and homes become more affordable. Confidence is growing. A widely tracked index of investor sentiment in Germany has turned positive for the first time in almost two years.
All this is welcome—not least because the slump has been made so much worse by panic and despair. When the financial system was on the brink of collapse in September, investors shunned all but the safest assets, consumers stopped spending and firms shut down. That plunge into the depths could be succeeded by a virtuous cycle, where the wheels of finance turn again, cheerier consumers open their wallets and ambitious firms turn from hoarding cash to pursuing profits
But, welcome as it is, optimism contains two traps, one obvious, the other more subtle. The obvious trap is that confidence proves misplaced—that the glimmers of hope are misinterpreted as the beginnings of a strong recovery when all they really show is that the rate of decline is slowing. The subtler trap, particularly for politicians, is that confidence and better news create ruinous complacency. Optimism is one thing, but hubris that the world economy is returning to normal could hinder recovery and block policies to protect against a further plunge into the depths.
Luminous Indicators
Begin with those glimmers. It is easy to read too much into the gain in share prices. Stockmarkets usually rally before economies improve, because investors spy the promise of fatter profits before the statisticians document a turnaround. But plenty of rallies fizzle into nothing. Between 1929 and 1932, the Dow Jones Industrial Average soared by more than 20% four times, only to fall back below its previous lows. Today’s crisis has seen five separate rallies in which share prices rose more than 10% only to subside again.
