Overview
- JGB yields climbed to levels not seen in decades in mid-July, with 10-, 20- and 30-year yields pushing toward roughly 2.8%, 3.8% and above 4% respectively.
- The shift follows the Bank of Japan's end to yield-curve control and continued policy normalization, which allowed market forces to drive long-term rates higher.
- Recent long-dated auctions drew strong demand, including a July 30-year sale with a bid-to-cover around 4.55 and record inflows into 20–30 year paper in 2025.
- Higher domestic yields have sent Japanese investors to repatriate funds, including about $29.6 billion of U.S. debt sold in Q1 2026, and have pulled money away from risk assets such as crypto.
- Policy and fiscal risks cloud the outlook because Japan's debt-to-GDP exceeds 200%, the government is asking pension funds like GPIF to consider more domestic holdings, and insurers could be forced sellers if ultra-long yields rise further.
