The effectiveness of non-conventional monetary policy
The latest IMF publications on non-conventional monetary policies affirm their effectiveness. This seems to hold true for all major forms, i.e. government bond purchases, forward guidance, and private asset purchases. However, bond purchases are likely to yield diminishing effects going forward. Their initial stimulus seems to owe much to the signalling of commitment and the repair of broken markets. Also, the economic impact seems to have a time limit. Meanwhile additional credible yield compression becomes ever more difficult as the zero boundary is drawing closer and central banks would struggle to extend commitments to ever longer durations.
