Real interest rates of world's major central banks
The world's major central banks have long followed the same general flight path, guided by the economic winds of growth, inflation and financial markets. It has worked pretty well for policymakers in the United States, Europe, Japan, and the United Kingdom: moving together to tighten or loosen monetary policy makes things more predictable for citizens, businesses and investors. It also serves as buffer to any volatile currency movements, at least among developed economies. But six years after the worst recession in decades, this could be the year central bankers split off and - with some risk - go their own way.
