Japan Bond Meltdown Sends Yields to Record High on Fiscal Fears

Key Points

  • Record High Yields: Japanese bond yields, particularly the 40-year rate, surged past 4% to the highest level since 2007, marking a historic peak for any maturity of Japan’s sovereign debt in over three decades.**
  • Investor Concerns: Investors are wary of Prime Minister Sanae Takaichi’s proposed food tax cut, fearing it will be funded by increased government bond issuance, exacerbating fiscal concerns.**
  • Global Impact: The volatility in Tokyo’s bond market is spilling over into global markets, affecting US Treasuries, Australian, and New Zealand bonds, with potential risks of a broader JGB meltdown.**
  • Attractive Market: Despite the selloff, the spike in yields is drawing foreign investors, who now dominate monthly cash JGB transactions, while Singapore Exchange Ltd. plans to introduce futures on longer-dated Japanese bonds.**

Summary

The Japanese bond market experienced a significant slump, with yields reaching record highs, as the 40-year rate surpassed 4% for the first time since its 2007 debut. This surge, driven by investor skepticism over Prime Minister Sanae Takaichi’s proposal to cut food taxes without a clear funding source, has led to fears of increased government bond issuance. Since Takaichi’s October appointment, 20- and 40-year yields have risen by about 80 basis points, reflecting broader concerns over government spending and inflation. The volatility in Tokyo has rippled into global markets, impacting US Treasuries and bonds in Australia and New Zealand. Despite the selloff, the higher yields are attracting foreign investors, who now account for 65% of monthly cash JGB transactions. Meanwhile, local insurers sold a record amount of long-term bonds in December, signaling bearish sentiment. As Takaichi calls for a snap election on February 8, the bond market remains a critical indicator of investor confidence, with potential global repercussions if a JGB meltdown intensifies.
