“More than six years after the onset of the Global Financial Crisis, central banks are being forced to fight a sudden battle against disinflation amid the ongoing silent war against deflation. Over the past couple of weeks, a number of central banks have shifted to a dovish stance on the future direction of interest rates, if not outright monetary easing. Although the slowing global economy is the primary factor behind their about-face in policymaking, the collapse in crude oil prices along with anticipation of other central banks’ future moves is what’s driven their timing. Many of these moves have caught a lot of people, including traders, economists and other financial experts, by surprise.”
