Japan’s Experience with Yield Curve Control

In September 2016, the Bank of Japan (BoJ) changed its policy framework to target the yield on ten-year government bonds at “around zero percent,” close to the prevailing rate at the time. The new framework was announced as a modification of the Bank's earlier policy of rapid monetary base expansion via large-scale asset purchases—a policy that market participants increasingly regarded as unsustainable. While the BoJ announced that the rapid pace of government bond purchases would not change, it turned out that the yield target approach allowed for a dramatic scaling back in purchases. In Japan’s case, the commitment to purchase whatever was needed to keep the ten-year rate near zero has meant that very little in the way of asset purchases have been required.
