Guidance: We do not expect Treasury’s guidance on coupon issuance to change in this Refunding round ("Treasury anticipates maintaining nominal coupon and FRN auction sizes for at least the next several quarters.")
Coupon sizes for upcoming quarter (Nov-Jan): As seen in table below. The Refunding itself will be $58B in new 3Ys, $42B in new 10Y, and $25B in new 30Y for next week.
Buybacks: After being in some focus in August's Refunding, we don’t expect any changes to buyback program parameters this time, following the last round’s amendments that included higher-frequency operations/increasing the size of long-end buybacks. There are some risks that buyback sizes could be slightly increased, or that Treasury announces that the list of eligible counterparties will be expanded.
Bill guidance: This will be of some interest given that borrowing expectations for the coming quarter were at the lower end of the expected range - one thing to watch will be if Treasury guides to reducing bill auction sizes soon having increased them significantly in late September/early October, helping push the TGA cash pile to the $1T mark. Last time that guidance read: "Treasury anticipates further marginal increases in short-dated Treasury bill auction sizes in the coming days and then maintaining sizes at or near those levels through the end of September. Additional increases to Treasury bill auction sizes are anticipated in October. Treasury will carefully monitor market conditions and adjust its bill issuance plans as appropriate. "
