Japanese bond yields are the highest in 40 years. The budget and a ‘red flag’ from PM Takaichi have markets nervous Japanese Prime Minister Sanae Takaichi is implementing a supplementary budget to address the cost of living, but it has triggered market skepticism regarding debt issuance, causing 10-year sovereign bond yields to reach their highest point since 1996. Despite assurances of unchanged total bond issuance for 2026 and financing through deficit-covering bonds, analysts point to the unusual calendar-year timeframe as a ‘red flag’ and believe increased spending necessitates increased debt. While some analysts view the budget as targeted household support rather than broad stimulus, aligning with Takaichi’s philosophy and recent positive economic data, concerns persist in the bond market about fiscal risks, inflation, and potential bond supply increases.
