Out of ammo?

WORLD stockmarkets are in bear territory. Gold, a haven in times of turmoil, has had its best start to a year in more than three decades. The cost of insurance against bank default has surged. Talk of recession in America is rising, as is the implied probability that the Federal Reserve, which raised rates only in December, will be forced to take them back below zero.One fear above all stalks the markets: that the rich world’s weapon against economic weakness no longer works. Ever since the crisis of 2007-08, the task of stimulating demand has fallen to central bankers. The apogee of their power came in 2012, when Mario Draghi, boss of the European Central Bank (ECB), said he would do “whatever it takes” to save the euro. Bond markets rallied and the sense of crisis receded.
