US 10-Year Treasury Yields Lock Above 5% on Deficits, Oil and AI-Driven Spending

The Bloomberg report frames the move as a potential regime change rather than a cyclical selloff. Primary drivers cited include Brent crude near $100, accelerated corporate AI capital expenditure, and structural budget deficits that have pushed the national debt past $40 trillion. These factors have lifted term premiums and reduced foreign demand for Treasuries at the margin.

What the coverage underplays is the direct transmission to retail and institutional bond portfolios. Higher yields have already produced mark-to-market losses for holders of longer-duration debt, while simultaneously raising the cost of new issuance for corporations and municipalities that must roll over maturing paper. This creates a feedback loop in which private credit markets tighten even as the Treasury continues to auction larger volumes.

The Fed’s reaction function remains the decisive variable. Minutes and dot-plot projections show officials treating inflation above target as the dominant risk, giving little room to ease even if growth moderates. Absent an exogenous shock large enough to force a policy pivot, the 5% floor on the 10-year is likely to persist through at least the first half of 2027.
