Central bankers have done everything in their power to finesse these problems. Under the leadership of Ben Bernanke and his predecessor, Alan Greenspan, the Fed condoned asset and credit bubbles, treating them as new sources of economic growth. Bernanke has gone even further, arguing that the growth windfall from QE would be more than sufficient to compensate for any destabilizing hot-money flows in and out of emerging economies. Yet the absence of any such growth windfall in a still-sluggish US economy has unmasked QE as little more than a yield-seeking liquidity foil.
The QE exit strategy, if the Fed ever summons the courage to pull it off, would do little more than redirect surplus liquidity from higher-yielding developing markets back to home markets. At present, with the Fed hinting at the first phase of the exit – the so-called QE taper – financial markets are already responding to expectations of reduced money creation and eventual increases in interest rates in the developed world.
Never mind the Fed’s promises that any such moves will be glacial – that it is unlikely to trigger any meaningful increases in policy rates until 2014 or 2015. As the more than 1.1 percentage-point increase in 10-year Treasury yields over the past year indicates, markets have an uncanny knack for discounting glacial events in a short period of time.
