Writing a piece in the Nikkei, this from Shirai on where the Bank of Japan should go from here

  • the likelihood of achieving 2% inflation is low
  • underlying inflation is weak
  • BOJ may find it necessary to revise its QQE

More:

  • Before taking any clear steps toward monetary policy normalization, the BOJ should introduce flexibility in interpreting the 2% price stability target.
  • It should incorporate the 1% upper and lower range (plus or minus 1%) of the target into the 2% target itself.
  • The BOJ and the government would then not need to abandon the 2% target while in practice aiming at a 1% figure that would be acceptable to the public.
