[MARKET ANALYSIS] Fixed income muted as focus turns to the US Treasury primary dealer questionnaire

The quarterly refunding questionnaire has historically been the venue where the Treasury telegraphs shifts in coupon auction sizes before the refunding announcement itself, and dealer surveys of this kind tend to move the curve in the direction of the expected composition change rather than on the announcement day itself. The live distinction here is between trimming long-end sizes and restructuring issuance toward bills: the former flattens the coupon supply curve and supports the back end, while sustained bill substitution shortens the weighted average maturity of outstanding debt and has, in past episodes of bill-heavy funding, drawn scrutiny over Treasury's duration management. Talk of eliminating a specific point on the curve altogether is rarer and, where floated in the past, has tended to concentrate pressure in that sector's liquidity premium well before any formal decision. The usual sequence is questionnaire, dealer estimates circulated by the banks, then the refunding statement itself, with the 20-year and 30-year auction tails in the interim serving as the tell. On the UK side, reported plans to raise the bank surcharge sit within a pattern of pre-Budget revenue signalling, and the question for Gilts is whether such measures close enough of the fiscal gap to alter the DMO's issuance remit at the margin.
