Economist warns of weakening demand for U.S. Treasuries as yields climb

Brookings Institution senior fellow Robin Brooks says rising long-term Treasury yields indicate weaker demand for U.S. debt than appears, despite weak economic data that would normally lower yields. He points to the $40 trillion national debt and government spending as if borrowing costs were still at crisis-era lows. The situation is described as an all-hands-on-deck effort to prevent long-term borrowing costs from rising further.
Brooks highlights specific policy maneuvers, including Treasury Secretary Scott Bessent's increased debt buybacks and Fed Chair Kevin Warsh's recent market reassurance, as evidence of an urgent push to contain long-term borrowing costs. He observes that recent weak economic indicators have failed to lower yields, breaking a historical correlation that typically signals a slowing economy.
The buyer base for U.S. debt is also transforming, with foreign central banks reducing their footprint and shifting toward gold, while hedge funds—highly sensitive to price—now play a larger role. This transition, combined with a projected $2 trillion annual deficit and rising oil prices from geopolitical tensions, compels the government to offer higher yields to attract investors.
If long-term Treasury yields continue to climb, the ripple effects could reach ordinary households through higher mortgage rates, auto loans, and corporate borrowing costs. A persistent shift in demand away from U.S. debt may force the government to allocate more of its budget toward interest payments, potentially crowding out public services or leading to future tax adjustments. Furthermore, increased market volatility driven by hedge funds could make global financial conditions more unpredictable, affecting pension funds and international investors who rely on stable returns.
