Japan’s 10-year bond yield hits highest since 1996

Japan's benchmark 10-year government bond yield surged to 2.925% on Monday, its highest level since September 1996, as a global selloff in sovereign debt intensified amid persistent inflation and expectations of further Bank of Japan rate increases.theedgemalaysia

The yield has now risen for six consecutive sessions, its longest winning streak in more than a year. The move came alongside broad weakness across the Japanese yield curve: the two-year yield climbed 3.5 basis points to 1.685%, its highest since May 1995, while the five-year yield rose to a record 2.155%. At the long end, the 30-year yield advanced to 4.06% and the 40-year yield reached 4.115%.theedgemalaysia

Global Bearishness and BOJ Uncertainty

The selloff in Japanese bonds tracked weakness in global debt markets. U.S. Treasuries fell on Friday after an initial rally driven by weaker retail sales data faded, while eurozone yields also ended last week higher.theedgemalaysia

"A bearish outlook on government bonds is spreading globally, and the upward trend in yields is intensifying, which is a cause for concern," said Keisuke Tsuruta, a senior bond strategist at Mitsubishi UFJ Morgan Stanley Securities ↘ 0.17%. He noted that "uncertainty surrounding the Bank of Japan's pace of interest rate hikes and its terminal rate remains a key concern."theedgemalaysia

The pressure on bonds comes as Japan's economy underwhelmed, expanding at just a 1.1% annualized pace in the second quarter, below the 2.0% median forecast, with flat consumer spending and a 1.2% drop in business investment. The Nikkei 225 slipped on the combination of disappointing growth and rising borrowing costs.finimize

Debt Crisis Warnings

The yield spike has drawn sharper warnings from analysts. Robin Brooks, writing on Substack, argued that Japan's yield curve steepening is statistically extreme, with the slope at the long end registering near two standard deviations above historical norms — a level he called consistent with a de facto debt crisis. Brooks noted that Japan's long-running policy of capping yields has transformed what would be a debt crisis into persistent currency weakness, explaining why repeated intervention has failed to stabilize the yen durably.robinjbrooks.substack

That analysis aligns with the aftermath of last month's coordinated U.S.-Japan currency intervention — the first since 1998 — which briefly pushed dollar/yen from near 160 to the mid-150s before the pair drifted back toward pre-intervention levels. Neuberger Berman's Joe Amato wrote that "durable yen strength will likely require further BoJ normalization and a genuine narrowing of the rate gap with the U.S. — something intervention alone cannot deliver."nb

With markets now watching for a possible BOJ rate hike as early as September, and Japan's debt-to-GDP ratio among the highest in the world, the tension between fiscal sustainability and monetary normalization shows no sign of easing.
