Japan: 30-year bond yield hits 30-year high

The Japanese long-term rate breaks a ceiling that has been in place for a third of a century. The real risk in July is not the BoJ decision itself, but the JPY carry trade that is still fueling US equities.

The fact

On July 8, 2026, the yield on the Japanese benchmark bond hits a 30-year high amid fears of inflation and fiscal health (Investing.com). USD/JPY remains near its 40-year low (~158-160). The Japanese government has incorporated the notion of "appropriate monetary policy" into its annual plan (recall publication #808) - a signal of non-opposition to BoJ normalization.

Our analysis

The Japanese bond market is openly stating what the Ministry of Finance is quietly hinting at: the era of zero rates is coming to an end. The real risk is not the BoJ decision of July 30-31 as such, but the unwinding of the JPY carry trade that has fueled five years of flows into US equities. Recall: the mini-crash of August 5, 2024 was triggered by a poorly telegraphed BoJ hike. This time, the double calendar of FOMC on July 29-30 + BoJ on July 30-31 adds a layer.

To watch

• BoJ decision on July 30-31: signal of normalization pace.
• USD/JPY breakout at 155 or 165.
• Long-term Japanese debt: bunds and treasuries in echo.
