The yield on the 30-year U.S. Treasury has climbed to its highest level in nearly two decades, but some Wall Street strategists are warning that the selloff in long-term government bonds may have further room to run.

The 30-year Treasury yield rose more than 4 basis points Monday to 5.311%, its highest level since June 2007, according to CNBC.

Foreign demand for U.S. government debt is showing signs of weakening. Treasury Department data released Monday showed that foreign holdings of Treasuries declined in June, with three of the biggest holders, the United Kingdom, Japan and China, all reducing their positions.

Several forces could determine whether the 30-year yield keeps climbing. One is the global bond market. Newton pointed to Japan, where government bond yields moved higher after weaker-than-expected economic growth was accompanied by a hotter GDP deflator, a measure of price changes across the economy.

"Ten-year and twenty-year JGB yields pushed higher, and it spilled right over into U.S. markets, driving the long bond to new multi-year highs," Newton said.

Another threat to bonds is the possibility that the Federal Reserve may need to keep monetary policy tighter than investors anticipate, or even raise interest rates further. Deutsche Bank said markets are effectively betting on a favorable combination of resilient economic growth, record-high stock prices, limited additional central-bank tightening and manageable commodity disruptions.

"By definition, strong growth and buoyant risk assets mean that financial conditions will remain accommodative, raising demand and pushing central banks into faster rate hikes," Deutsche Bank macro strategist Henry Allen wrote.

Inflation remains above the Federal Reserve's target. Deutsche Bank's historical analysis found that consumer inflation above 3% has typically been associated with more than 100 basis points of tightening during the first year of Fed hiking cycles.

Investors have seen similar repricing before. At the end of 2023, the 10-year Treasury yield stood at 3.88%. By late April 2024, it had surged to around 4.70% as stronger economic growth and persistent inflation forced markets to abandon expectations for rapid Fed rate cuts.

A third source of pressure is increasingly important for the 30-year bond: the amount investors demand to be compensated for holding government debt for decades. Heavy Treasury issuance is testing appetite for long-term securities.

BMO noted that the latest 30-year Treasury auction cleared at its highest yield since 2001. Five of the previous seven 20-year auctions also "tailed," meaning investors demanded higher yields than markets had anticipated.

Energy prices and inflation could make the situation more difficult. A renewed commodity shock could simultaneously weaken economic growth while keeping inflation elevated, creating a particularly challenging environment for both stocks and bonds.

The unusual part of the current Treasury selloff is that yields have remained stubbornly high even as some economic indicators soften. July retail sales posted their weakest performance since May 2025, while recent labor-market figures have pointed to cooling conditions.
