U.S. 30-Year Treasury Yield Closes at 5.15% as Long-Bond Pressure Persists

Deficit concerns, inflation risks and rising corporate financing needs are increasing competition for long-duration investors.

The U.S. 30-year Treasury yield closed at 5.15% on Wednesday, extending a 12-session run above 5% and underscoring continued pressure on the long end of the government bond market.

According to industry-compiled data, the 30-year yield has traded above 5% for 27 sessions this year, or about 19% of trading days. That is the highest number of such sessions since 2007, when the yield spent 50 days above that threshold. The recent 12-day streak also exceeded an 11-day run in May, when the yield reached 5.2%, its highest level since 2007.

The inflation-adjusted yield on 30-year Treasuries has risen by about 50 basis points this year to nearly 3%, a level last seen in 2008. The move comes even though the Federal Reserve’s benchmark rate is roughly 150 basis points lower than it was in 2007, indicating that investors are demanding a higher premium for holding debt with a 30-year maturity.

Long-term Treasury yields have been supported by concern over U.S. fiscal conditions and persistent inflation. The U.S. Treasury market has expanded from $4.5 trillion in 2007 to $31 trillion, while public debt has risen to more than 100% of GDP. Annual federal interest costs have exceeded $1 trillion.

Tony Rodriguez, head of fixed-income strategy at Nuveen, said high sovereign debt and fiscal deficits have helped keep long-term Treasury yields elevated.

Corporate financing demand is also adding to competition for long-term capital. More than $500 billion of AI-related financing is competing with government bond issuance for investors. Rodriguez said that governments, large technology companies and other borrowers are increasingly seeking funds from the same pool of long-duration buyers.

Alex Payne, a senior portfolio manager at Vanguard, said traditional buyers of 30-year Treasuries, including pension funds and insurers, now have a wider range of investment options than in recent years. He said it remained uncertain whether long-term Treasury yields had reached their peak.

The Treasury has relied heavily on short-term bill issuance in recent years while keeping longer-term bond issuance broadly stable. But pressure at the long end of the market has persisted as investors weigh the outlook for fiscal borrowing, inflation and competing demand for capital.
