[MARKET UPDATE] Limited Gilt reaction on the Chancellor's speech. Upside in Gilts on the DMO remit, size as expected and marked skew away from long-end. OBR commentary then pared some of this.

Limited Gilt reaction on the Chancellor's speech. Upside in Gilts on the DMO remit, size as expected and marked skew away from long-end. OBR commentary then pared some of this.

Gilt remit announcements follow a well-rehearsed sequence: the initial move comes on the headline size versus expectations, and the second, often more durable, move comes on the maturity split, since that is what determines where supply actually lands on the curve. Here the skew away from the long end fits the established pattern of long-dated Gilts rallying relative to the front and belly when syndication and auction calendars favour shorter maturities, reflecting the fact that long-end pricing remains highly sensitive to issuance composition given the concentration of structural buyers there and its reduced depth since the liability-driven episodes of recent memory. The partial retracement on OBR commentary is also typical: the OBR's fiscal arithmetic, particularly around borrowing needs and debt-servicing assumptions, tends to temper supply relief by reminding the market of the underlying issuance trajectory rather than the one-year remit. The distinction worth holding is between the remit as a composition signal, which flattens the long end, and the OBR outlook as a quantum signal, which works the other way if it implies more borrowing ahead. Follow-ons are the auction calendar detail, any changes to syndication plans for long and index-linked stock, and whether the curve move holds once the remit documentation is digested rather than just the headline figures. As a supply event rather than a policy one, the initial reaction is usually the sharper one and prone to partial fading.
