U.S. Treasury Auctions Total $839 Billion in One Week, Including $106 Billion in Additional Financing
Key Facts
U.S. Treasury auction volumes totaled $839 billion in the week ended October 30, 2026, a record across 11 auctions of bills, notes and floating-rate notes, according to Bloomberg News. Most of the amount went to repay holders of bills that had matured, so the total does not represent new net borrowing of that size. Bloomberg said only $106 billion of the auction proceeds represented additional financing for the federal deficit. This distinction puts the record figure in context: most issuance refinanced existing obligations, while the remainder provided additional financing. The Treasury estimated its net marketable borrowing from private-sector investors at about $628 billion for the October-to-December 2026 quarter, assuming an end-of-quarter cash balance of $850 billion.
Against the backdrop of financing needs, the Congressional Budget Office estimated the federal deficit for fiscal 2026 at about $1.9 trillion, or 5.8% of gross domestic product, compared with a deficit of $1.8 trillion in 2025. The estimate puts the current deficit near $2 trillion, while weekly auction proceeds remain a mix of refinancing and additional financing. U.S. real gross domestic product grew at an annual rate of 3.4% in the third quarter, after growing 2.2% in the second quarter, according to the Associated Press. On October 28, the Federal Reserve kept its target interest rate range at 3.75% to 4%, with the decision approved by a 10-to-2 vote. September data from the Bureau of Economic Analysis showed the core personal consumption expenditures price index rose 3.1% year over year, compared with a 3.6% increase in the headline index.
On a monthly basis, the core personal consumption expenditures price index rose 0.3% in September, the same increase recorded in August. Disposable personal income increased 0.2% during the month, while nominal personal consumption expenditures rose 0.5%, according to the Bureau of Economic Analysis. These readings came as the Fed kept its rate range unchanged, with inflation and spending data forming part of the backdrop to discussions about financing and borrowing costs. In markets, the two-year Treasury yield fell to 4.69% on October 28 after topping 4.79%, according to the Associated Press. The 10-year Treasury yield rose to 5.02% from 4.99% late the previous day.
In a separate issue affecting households and public spending, KFF estimated that the average final increase in benchmark silver plan premiums in Affordable Care Act marketplaces will be 13% in 2027, after those premiums rose 26% between 2025 and 2026. That figure differs from the median increase insurers requested in their 2027 filings, which was 15%, according to KFF's analysis of filings from 276 insurers in all 50 states and the District of Columbia. Insurers attributed the proposals to rising health care service costs, economic inflation and labor shortages. They also cited the expiration of enhanced tax credits at the end of 2025 and changes in the health risks of enrollees among the factors behind their requested increases. According to Congressional Budget Office estimates, net federal support for health insurance is $2.4 trillion, or 7.4% of GDP, in 2026, and could reach $3.9 trillion, or 8.4% of GDP, in 2036 under current law.
The Centers for Medicare & Medicaid Services says more than 75% of people buying coverage through HealthCare.gov will still be able to access premiums of no more than $50 in 2027. Open enrollment to choose coverage for next year begins on November 1, 2026, and ends on January 15, 2027, according to the agency. This puts premium estimates in the context of the upcoming selection period for enrollees, alongside continued projections for federal health support over a longer horizon. On the budget front, the Congressional Budget Office estimated that permanently extending the expanded premium tax credits would increase the cumulative deficit by $350 billion between 2026 and 2035 compared with the baseline. The office also estimated that the extension would increase the number of insured people by 3.8 million in 2035.
Upcoming scheduled releases include the September Job Openings and Labor Turnover report, which the Bureau of Labor Statistics has set for November 3, 2026. The following day, the Treasury plans to publish its quarterly refunding announcement on November 4, with financing details included in the announcement. The announcement comes as the department expects net borrowing of $628 billion in the October-to-December quarter, assuming an end-of-quarter cash balance of $850 billion. These announcements will provide data on the labor market and the Treasury's financing plans for the coming period, while the $839 billion figure describes total weekly auction volumes. Additional financing within that total amounted to $106 billion, according to Bloomberg News.
