On Friday, the central bank raised the policy rate by a quarter point to a three-decade peak of 0.75%, in a clearly telegraphed move. But while the accompanying statement signalled a readiness to continue tightening policy, BOJ Governor Kazuo Ueda stuck to his usual cautious rhetoric in his news conference.
Ueda is due to speak at Japan’s Keidanren business lobby on Christmas Day, offering markets another opportunity to parse any policy clues.

The euro eased 0.1% to 184.42 yen , staying within touching distance of Friday’s record peak at 184.75. The single currency was 0.1% stronger at $1.1720 .
The Swiss franc rose 0.4% to 197.91 yen after touching a record 198.22 yen early in the session.
The Aussie was 0.6% firmer at 104.16 yen , having earlier reached the strongest levels against the yen since July of last year.
