Watch out

THE struggle has been long and arduous. But gazing across the battered economies of the rich world it is time to declare that the fight against financial chaos and deflation is won. In 2015, the IMF says, for the first time since 2007 every advanced economy will expand. Rich-world growth should exceed 2% for the first time since 2010 and America’s central bank is likely to raise its rock-bottom interest rates.

However, the global economy still faces all manner of hazards, from the Greek debt saga to China’s shaky markets. Few economies have ever gone as long as a decade without tipping into recession—America’s started growing in 2009. Sod’s law decrees that, sooner or later, policymakers will face another downturn. The danger is that, having used up their arsenal, governments and central banks will not have the ammunition to fight the next recession. Paradoxically, reducing that risk requires a willingness to keep policy looser for longer today.
