The Japanese Ministry of Finance (MoF) will today sell Y800bn of 30-Year JGBs. The MoF last sold 30-year debt on 8 April 2025.
- This month’s 30-year JGB auction features an outright yield approximately 50–55 basis points higher than last month’s issuance. Notably, the current yield is hovering just below its cycle high of 3.0%.
- The 10s30s yield curve is now 5–10 basis points steeper than at the time of the previous auction, though still around 10 basis points below its recent peak.
- On a relative value basis, the 30-year bond remains largely unchanged versus last month when viewed through the 20-/30-/40-year butterfly spread.
- Today's supply comes amid weakening sentiment toward longer-dated global bonds, weighed down by positive trade deal developments, consistently strong U.S. economic data, and a further pushback in expectations for Fed rate cuts.
- Against this backdrop, today’s 30-year auction will serve as a key gauge of investor appetite in the face of heightened uncertainty.
- Results are due at 0435 BST / 1235 JT.
