The US Treasury's August 2026 quarterly refunding guidance left coupon auction sizes unchanged through at least 2027, even as federal deficits widen. The gap is being filled by elevated T-bill issuance, extending a pattern that has kept the short end of the curve supply-heavy for several consecutive quarters. This is not a temporary tactical choice; Treasury is explicitly relying on bills as a structural funding lever.
For Armada's traditional repo desk, a sustained bill overhang compresses short-term rates and can pressure SOFR lower, squeezing repo spreads on Treasury collateral. It also affects counterparty behavior: MMFs and asset managers absorbing bill supply may reduce demand for term repo, shifting duration and rate expectations across the book.
