Japan’s equity markets rallied sharply on Thursday, propelled by a surge in risk appetite after the U.S. Treasury Department moved to stabilize the global bond market. The benchmark Nikkei 225 Index climbed 1.00% to close the morning session at 65,982.49, while the broader Topix Index gained 0.91% to 4,048.72.
The rebound offers welcome relief to Asian risk assets following multi-decade highs in borrowing costs across the United States, Germany, and Japan, which had rattled global market sentiment earlier in the week.
U.S. Yield Interventions Quell Rate Anxiety
The global fixed-income sell-off stalled overnight after the U.S. Treasury announced plans to double the size of its long-duration debt buybacks. The liquidity injection prompted a sharp pullback in U.S. Treasury yields, effectively easing borrowing-cost pressures across global markets and sparking an immediate rotation into risk equities.
According to Nomura Securities equities strategists, the sudden drop in sovereign yields served as the primary catalyst for Thursday’s stock market pop. Crucially, market participation broadened beyond high-beta artificial intelligence and semiconductor names, driving substantial gains in previously lagging value and cyclical sectors.
Sector Rotation: Materials and Utilities Lead, Tech Cools
Market breadth on the Nikkei 225 was overwhelmingly bullish, with 175 advancing stocks outstripping 48 decliners.
Traditional value sectors—including metals, pharmaceuticals, and power utilities—dominated the top percentage gainers list as lower yields relieved valuation pressures. Conversely, chip suppliers and technology component makers experienced localized profit-taking as capital reallocated toward non-tech sectors.
| Top Market Movers | Ticker / Sector | Performance (%) | Driver / Catalyst |
| Sumitomo Metal Mining | Materials / Mining | +9.72% | Yield easing & commodity demand recovery |
| Sumitomo Pharma | Healthcare | +8.70% | Defensive value rotation |
| Kansai Electric Power | Utilities | +8.09% | Sharpest single-day surge since Aug 2024 |
| Rohm Co. | Tech / Semiconductors | -3.88% | Capital rotation out of chip supply chains |

Outlook for Investors
While the U.S. Treasury’s buyback program has successfully contained sovereign bond volatility in the short term, market participants remain cautious. Equity durability through the end of the month will depend heavily on upcoming global inflation readings and whether central banks can keep long-term borrowing costs anchored without further central market interventions.
