The debt wall

The US is approaching a sizeable debt wall. As the chart shows, a very large amount of Treasury debt matures over the coming years, with 2026 particularly heavy because of the huge stock of short-term bills.

The issue is not repayment capacity, but refinancing cost. Debt issued when rates were much lower is progressively being rolled over at today’s higher yields. Unless interest rates fall materially, this mechanically pushes the US government’s interest bill higher and makes fiscal deficits more expensive to finance.

This is another reason why the level of bond yields matters well beyond the bond market: higher-for-longer rates increasingly feed directly into government finances.
