Federal borrowing and interest costs through June were reported by Eleanor Pringle at Fortune. The deficit for the first nine months of fiscal 2026 came to just under $1.4tn, against just over $1.3tn in the same stretch of fiscal 2025. That averages about $155bn a month, or $39bn a week. Interest on the debt cost $857bn over the nine months, up about $100bn, or 13 percent, from a year earlier. That is roughly $23.8bn a week. Social Security spending rose $62bn, Medicare $58bn and Medicaid $49bn. Total debt stood at $39.4tn. Maya MacGuineas of the Committee for a Responsible Federal Budget said the full-year deficit is expected to reach $2tn or more.
