(revision) US Treasury TBill Auction Schedule totals ~$12.2 trillion short term liquidity to be issued. 122 distinct T-Bill auctions in this schedule. The Tentative Auction Schedule PDF (the current version as of February 2026, covering auctions primarily from early February 2026 through early August 2026, roughly a 6-7 month horizon) includes the following distinct Treasury Bill (T-Bill) auctions, based on the listed auction dates per tenor: 4-Week Bill: 20 auctions 6-Week Bill: 16 auctions 8-Week Bill: 20 auctions 13-Week Bill: 20 auctions 17-Week Bill: 20 auctions 26-Week Bill: 20 auctions 52-Week Bill: 6 auctions (Short-term T-Bills are generally auctioned weekly, while 52-week are roughly monthly/every 4 weeks. Counts are tentative and may shift slightly for holidays, but no major omissions are noted.)Auction sizes vary by tenor and aren't uniform ~$100 billion each—recent actual/typical sizes (from 2025–2026 data) are more like:4-week, 6-week, 8-week: Often $90–$110 billion (e.g., recent 4-week at up to $110B record, others commonly $95B) 13-week: Around $80–$90 billion (e.g., recent ~$89B) 17-week: Historically lower when introduced (~$30–$40B), but now aligned closer to benchmarks, often $60–$90B range in practice 26-week: Similar to 13-week, ~$80–$90B or higher 52-week: Typically lower, often $40–$60B or so (less frequent, so sized accordingly) Using approximation of ~$100 billion per auction across the board (a reasonable rough average for many short-term tenors in the current environment, though it overstates some longer ones slightly):Total gross amount auctioned in T-Bills over this schedule ≈ 122 auctions × $100 billion = $12.2 trillion home.treasury.gov/system/files/2…
