Japan’s yield curve control: the basics

The Bank of Japan has once again broken new grounds in monetary policy, now targeting not just the short-term policy rate but – within limits – the 10-year JGB yield. In practice the Bank will secure a positive yield curve against the backdrop of negative short-term rates and negative expected long-term real rates. This is meant to mitigate the debilitating effect of yield compression on the financial system and, probably, to contain the risk of bond yield tantrums in case domestic spending and inflation do pick up. As a side effect, the policy would subsidize long duration carry trades and long-long equity-duration risk parity positions.
