The 10-year, 10-year forward Treasury yield held firm during this week’s AI-linked market decline even as two-year and 10-year yields fell, a split Robin J Brooks says points to growing fiscal risk.
Brooks, author of a Nov. 7 post, examined the 10-year, 10-year forward Treasury yield to assess whether investment in AI infrastructure has helped drive long-term rates higher. That yield did not fall alongside shorter Treasury yields during the market downturn, he wrote. He argues the pattern supports his view that fiscal concerns are playing a larger role in long-term borrowing costs than AI investment.
Brooks said current yields at the long end of the Treasury market exceed levels seen before the global financial crisis. He challenged the idea that hyperscaler borrowing is the main cause, pointing to a historical gap between corporate and public dissaving. The corporate measure he uses to capture hyperscaler debt issuance remains well below its early-2000s IT-bubble level, he wrote, while public dissaving looks unusually large by comparison.
He also assessed how bond yields moved after the latest U.S. payroll figures. Bloomberg’s consensus was 70,000 jobs, compared with an actual 165,000, Brooks wrote. The 95,000 upside surprise was 1.2 times the historical standard deviation of 76,000 that he cited. Brooks said the five-basis-point rise in the two-year Treasury yield was larger than he would expect if AI were a major part of U.S. growth.
The fiscal debate comes as borrowing costs have drawn wider attention. The International Monetary Fund has urged governments to strengthen public finances as costs rise. EconoTimes previously covered IMF warnings alongside U.S. and French fiscal projections.
Brooks placed rapidly diminishing fiscal space at the top of the structural challenges facing the United States and other Group of 10 economies. His post did not identify a next scheduled decision or indicator.
