One of the most dramatic monetary interventions in recent years has been the unprecedented surge in global central bank balance sheets. This form of “money printing” has not had the inflationary effect predicted by pessimists, but there is still deep unease among some central bankers about whether these bloated balance sheets should be accepted as part of the “new normal”. There are concerns that ultra large balance sheets carry with them long term risks of inflation, and financial market distortions.
In recent weeks, there have been debates within the FOMC and the ECB Governing Council about balance sheet strategy, and it is likely that there will be important new announcements from both these central banks before the end of 2017. Meanwhile, the PBOC balance sheet has been drifting downwards because of the large scale currency intervention that has been needed to prevent a rapid devaluation in the renminbi. Only the Bank of Japan seems likely to persist with policies that will extend the balance sheet markedly further after 2017.
Globally, the persistent increase in the scale of quantitative easing is therefore likely to come to an end in 2017, and it is probable that central bank balance sheets will shrink thereafter, assuming the world economy continues to behave satisfactorily.
Investors have become accustomed to the benefits of “QE infinity” on asset prices, and are cynical about the ability and desire of central bankers ever to return their balance sheets to “normal”. They will have to adjust to a new reality fairly soon. Read more
