Bank of America said quantitative easing in Europe and Japan will cover just 35pc of the global stimulus lost as the Fed pulls back, creating a treacherous hiatus for markets. It warned that the full effect of Fed tapering had yet to be felt.

This is why we believe we are entering a phase in which bad news will be bad news and volatility will likely rise,” it said.
