The Unintended Consequences of Quantitative Easing

Quantitative easing, which saw major central banks buying government bonds outright and quadrupling their balance sheets since 2008 to $15 trillion, has boosted asset prices across the board. That was the aim: to counter a severe economic downturn and to save a financial system close to the brink. Little thought, however, was put into the longer-term consequences of these actions.

From 2008 to 2015, the nominal value of the global stock of investable assets has increased by about 40 percent, to over $500 trillion from over $350 trillion. Yet the real assets behind these numbers changed little, reflecting, in effect, the asset-inflationary nature of quantitative easing. The effects of asset inflation are as profound as those of the better-known consumer inflation.
