According to Jinshi Data, Bank of Japan Governor Kazuo Ueda will deliver a speech at the annual meeting, and the market is paying attention to his hints on the timing of interest rate hikes. As of last Friday, the swap market showed that the probability of the Bank of Japan raising interest rates in December was 53%.

Japan's economic growth data showed a recovery in consumption, and surveys and swaps markets showed a more than 80% chance of a rate hike before the January meeting. Rising wages have boosted household spending, which is seen as an important factor supporting continued rate hikes.

A weaker yen could prompt the Bank of Japan to act. Tokyo, which has spent more than $100 billion defending the currency this year, may want to avoid more direct intervention.
