The April JSDA bond trading data highlights a pivot by foreign investors away from flattener positions towards long-term JGBs, while domestic insurers and trust banks absorbed the supply in the super-long sector.

Key Takeaways

  • 1.Foreign investors shifted away from 'flattener' positioning, selling super-long JGBs for the first time since 2024 while making massive purchases of long-term JGBs.
  • 2.Japanese insurance companies became net buyers of super-long JGBs for the first time in nine months, likely attracted by higher absolute yields.
  • 3.Trust banks ramped up JGB purchases to over JPY1.3 trillion, primarily for portfolio rebalancing as global equity markets performed strongly.
