The BoJ’s Christmas surprise – why now and what’s next?

In December, the Bank of Japan surprised markets by widening the allowance corridor for the 10-year JGB yield target, aiming to fortify its Yield Curve Control policy. The shift effectively results in a tightening of monetary policy, although we think the impact on growth will be limited.

The BoJ's Christmas surprise - why now and what's next?

What you will learn:

  • Despite the BoJ’s aims, the tweak to the YCC policy has heightened speculation over further policy normalisation, pushing the central bank into greater intervention in the JGB market. However, distortions to the yield curve and dysfunction in the JGB market are persisting.
  • We still think that without a sustained rise in wages, achieving the 2% inflation target is not yet in sight and the BoJ will stick to its YCC policy, shrugging off continual challenges from foreign investors in H1 2023. In H2, a projected slowdown in growth and inflation together with rising expectations of a Fed pivot should gradually alleviate upward pressures on the yield curve.
  • At the same time, however, we now see a rising risk that December’s tweak to the YCC policy may herald the start of more tightening. If pressures on the yield curve persist, the BoJ might be forced to widen the allowance corridor further to buy time.

The BoJ looks to buy time as pressures mount

The Bank of Japan maintained its monetary policy settings at today’s (18th Jan) meeting. At the same time, the BoJ decided to enhance the funds-supplying operations to put downward pressure in the belly zone of JGB yield. Meanwhile, revisions in inflation outlook were smaller than we had expected. We think that the BoJ will continue to stick to its current Yield Curve Control policy ahead.
