US Treasuries: Refunding Offers Little Extra Long-End Support

Value Score: 8.5/10
Core Conclusion: Morgan Stanley expects the November 4 refunding to disappoint investors seeking cuts to long-dated Treasury issuance or larger buybacks. Its October 30 assessment finds insufficient evidence of market dysfunction to justify further support. The more consequential uncertainty is when the debt ceiling permits coupon issuance to rise in 2027, and how much short-term bill supply must absorb the adjustment.
Key Data Moves
Higher financing needs initially fall on bills. The bank raises its calendar-2026 deficit forecast by $185bn after weaker corporate tax receipts. It projects net borrowing of $2,026bn in 2026 and $2,158bn in 2027, with net bill issuance of $516bn and $632bn, respectively. These are forecasts, not announced auction volumes. Its financing table also distinguishes total issuance from supply reaching private investors after assumed Federal Reserve purchases and Treasury buybacks; those amounts should not be treated as interchangeable.

Existing buybacks appear sufficient for current liquidity demand. The maximum size of long-end operations has already risen from $2bn to $6bn. Subsequent operations have sometimes left capacity unused. The authors interpret this alongside broadly stable liquidity and relative-value measures as evidence of a price-sensitive liquidity program. They expect the $6bn cap to remain, rather than another expansion designed to suppress long-term yields (pp11-15).
Issuance Timing Matters More Than a Long-End Rescue
The baseline is modest coupon increases starting in February 2027, concentrated in shorter maturities and the belly, while long-end auction sizes remain unchanged. The bank envisages smaller $1bn steps at tenors below seven years spread over four quarters. November guidance could prepare investors for this adjustment; the report's proposed wording is an analyst expectation, not Treasury's published statement.
The debt ceiling can interrupt that timetable. As of October 28, public debt of $40.551tn left roughly $550bn below the statutory limit. Morgan Stanley estimates the limit becomes binding in February 2027, after which cash drawdowns and extraordinary measures would sustain payments. Its estimated late-thi
