# US Treasury Deficit Surges to $409 Billion in October Federal borrowing accelerates as fiscal year 2027 begins with significant budgetary shortfalls. - **Source:** [Fortune](https://fortune.com) - **Published:** 2026-11-10 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/06fdb532-0fa0-4735-a0f7-ac17d3021fdf ## October Deficit Spike The U.S. federal government recorded a $409 billion deficit in October 2026, marking the start of the 2027 fiscal year. This figure represents a $125 billion increase compared to the same month last year. Weekly borrowing exceeded $100 billion, driven by lower revenues and significantly higher government outlays during the period. ## Timing Shift Impact The Congressional Budget Office attributed the sharp deficit increase to specific timing shifts in federal payments. Payments originally scheduled for November 1 were moved into October because the date fell on a weekend. This accounting adjustment inflated the monthly deficit figure, distorting the immediate comparison with previous fiscal year start periods. ## Treasury Twist Strategy Treasury Secretary Scott Bessent implemented a strategy dubbed the Treasury twist to manage national debt. This approach involves buying back expensive long-term debt while issuing cheaper, short-term debt. Critics, including market analysts, have compared this maneuver to paying off a mortgage with a credit card, questioning its long-term fiscal sustainability. ## Market Analyst Skepticism James Sullivan of JPMorgan criticized the debt reshuffling, noting that such mismatches eventually become unsustainable. While the strategy aimed to lower long-term yields and smooth market volatility, it failed to impress financial observers. The move highlights the ongoing tension between managing immediate borrowing costs and maintaining long-term fiscal credibility for investors. ## Fiscal Trajectory Concerns The U.S. fiscal path remains a point of contention for debt hawks concerned about long-term sustainability. The 2026 fiscal year deficit reached 6.2% of GDP, a notable increase from 5.8% the previous year. This level significantly exceeds the 50-year average of 3.8%, signaling persistent structural challenges within the federal budget framework. ## Historical Deficit Context A deficit exceeding 6% of GDP is historically rare, having occurred only eight times since 1946. These instances were primarily concentrated during major economic crises, specifically between 2009 and 2012, and during the 2020, 2021, 2023, and 2024 fiscal years. Current figures suggest the government is maintaining high spending levels despite economic growth. ## Revenue and Spending Dynamics Total government income rose to $5.4 trillion for the 2026 fiscal year, bolstered by higher individual income and payroll tax collections. However, these gains were outpaced by a $217 billion increase in total outlays. Rising costs for Social Security, Medicare, and Medicaid remain the primary drivers behind the expanding federal expenditure profile. ## Interest Burden Reality The total deficit for the 2026 fiscal year reached $1.9 trillion, with interest payments on public debt accounting for $1.14 trillion of that total. As interest costs consume a larger portion of the budget, the government faces increasing pressure to balance rising mandatory spending with the necessity of maintaining stable debt levels. ## Sources covering this story - https://fortune.com/2026/11/10/cbo-october-budget-treasury-deficit-100-billion-weekly/ — --- _Summary written by Brifing from the original reporting.
