Japan's Ministry Holds the Line: 20 Billion Yen Monthly Bond Buybacks Signal No Emergency Backstop

Japan's Ministry of Finance has kept its JGB buyback program flat at roughly 20 billion yen monthly through July–September 2025, even as 40-year yields hit record highs of 3.675% in May. The consistency signals deliberate restraint: Tokyo will not panic-buy to suppress yields. By maintaining fixed monthly volumes across vastly different market conditions, authorities are saying the market must clear itself, not that officials will step in as a backstop buyer.
