Fiscal-risk premia
Updated
What it is
This tracks the "term premium" — the extra yield investors demand for holding long-duration government debt beyond what is justified by the expected path of short-term interest rates. The New York Fed's ACM model is a widely cited way of decomposing Treasury yields into an expected-rate component and this term premium, which rises when investors worry about inflation, debt supply, or sovereign creditworthiness. A rising premium can keep long-duration yields elevated even if the central bank is not actively tightening.
Why it matters lately
The ACM 10-year term premium reached 0.89% on August 17, 2026, its highest daily reading of the year, consistent with growing fiscal-supply concerns. Moody's had already downgraded the U.S. sovereign credit rating from Aaa to Aa1 in May 2025, citing a rising debt and interest burden and projecting federal debt could reach about 134% of GDP by 2035. Long-end yields reflected these concerns in 2026, with 30-year Treasury yields closing at 5.31% on August 17, 2026 (highest since June 2007) and UK 30-year gilt yields hitting 5.919% that year, their highest since 1998.
Asymmetric Analytics view
Inference (AA): AA watches fiscal-risk premia as a signal of whether markets are starting to price sovereign credit and deficit risk into long-duration government debt, which feeds into how the graph discounts other long-duration assets.
