Key Takeaways
- 1.The Bank of Japan (BOJ) is expected to maintain its current JGB purchase reduction plan through March 2027, as market functioning is improving and short-term rates remain stable.
- 2.Post-April 2027, the BOJ is likely to sustain monthly JGB purchases at approximately ¥2 trillion to avoid political friction and risks of yen depreciation associated with debt monetization concerns.
- 3.Short-term interest rates have remained stable despite shrinking current account balances, suggesting liquidity remains abundant in the money markets.
