Yields on 30-year U.S. Treasury bonds have remained above 5 percent for the 13th consecutive trading day, marking one of the longest such runs since 2007. This persistent elevation in long-term borrowing costs has prompted debate among investors and economists about whether these levels represent a new normal for the U.S. debt market or are nearing a peak.

Analysts attribute the sustained high yields to growing concerns over the fiscal outlook of the United States. Cliff Zhao, chief economist at CCB International, and the bank’s global strategist Vera Jiang noted that while short-term yields generally reflect Federal Reserve policy expectations, long-term yields increasingly incorporate worries about Washington’s fiscal sustainability. Investors appear to be demanding higher compensation for holding government debt over extended periods amid mounting U.S. debt levels.

“Persistently elevated yields may not immediately trigger a debt crisis but could restrict future fiscal policy options and lead to demands for a higher long-term risk premium,” Zhao and Jiang said. The passing of last year’s “One Big Beautiful Bill Act,” which combined substantial tax cuts with increased defense and border security spending, has further intensified fiscal concerns.

Geopolitical risks also contribute to these trends. Bosco Wu, an investment strategist at Bank of East Asia, highlighted that additional defense expenditures related to the ongoing conflict in Iran, along with uncertainty around tariff revenues, are placing upward pressure on long-term Treasury yields. However, Wu suggested the yields, currently trading between 5.1 and 5.2 percent, may be close to the upper range of his forecast absent renewed inflationary pressures prompting a more hawkish Federal Reserve stance.

With the Federal Reserve’s policy meeting approaching, market expectations have shifted away from imminent rate cuts. According to CME Group’s FedWatch tool, there is roughly a 66 percent probability that the Fed will maintain current rates, with about a 25 basis point increase factored into the remainder of the probability assessment. Christian Scherrmann, chief U.S. economist at DWS Group, pointed out there are no clear data signals justifying a change in policy at the upcoming Federal Open Market Committee meeting.

Meanwhile, economists are closely monitoring inflation data and its influence on Fed decisions. Karsten Junius, chief economist at Bank J. Safra Sarasin, noted that softer inflation figures in June have eased immediate pressure on the Fed to tighten further, though underlying price pressures persist.

The rise in Treasury yields has implications for global financial markets and asset allocation strategies. Zhao and Jiang observed that cash, money market funds, and short-duration Treasuries remain attractive, while longer-dated bonds experience greater volatility despite higher yields. In equity markets, elevated yields tend to favor companies with robust earnings, strong cash flow, and productive investments, while putting pressure on highly leveraged firms and those dependent on future profit growth.

The recent correction in shares related to artificial intelligence—after a period of heavy investor enthusiasm—reflected growing skepticism about returns amid ongoing inflation worries. For Chinese assets, Zhao and Jiang emphasized the impact of the U.S. dollar’s strength, the yuan exchange rate, and external liquidity conditions, although domestic A-shares and government bonds remain more sensitive to local policies and economic factors.

Wu added that while investors still see U.S. dollar assets as a safe haven, they are increasingly looking to diversify portfolios in a shifting global financial environment.
