[E7166] US total obligations are estimated at ~1,000% of GDP with interest expense already exceeding 100% of tax receipts as of January 2022. Fed rate hikes create a self-reinforcing debt trap: higher rates increase interest costs, worsen fiscal position, and push toward the 40%-of-tax-receipts threshold that historically triggers sovereign crises. This dynamic makes sustained tightening mathematically unsustainable.
