The UK sells GBP 4bln 4.875% 2036 Gilt: b/c 3.65x (prev. 3.13x), average yield 5.155% (prev. 5.040%), tail 0.1bps (prev. 0.1bps)

A conventional gilt auction clearing with a notably higher cover ratio than the prior sale, an average yield above the previous tap of comparable paper, and a tail unchanged at 0.1bp points to genuinely firm demand rather than a concession-driven clear. Tails this tight indicate the auction priced essentially on the screws, meaning the book was real and not padded by last-minute cheapening, a pattern that distinguishes healthy syndicated-style demand from the occasional weak UK sale that has produced multi-basis-point tails and forced a repricing across the curve. The step-up in cover against a higher yield suggests buyers were comfortable adding duration at these levels, which in past episodes of heavy UK supply has mattered because the gilt market has periodically shown indigestion when the DMO's issuance calendar runs hot. Worth noting is the distinction between demand for new paper at a yield premium to the secondary curve and outright risk appetite for gilts: strong auctions have coexisted with rangebound or softening outright levels when the concession was the attraction. The follow-ons are the post-auction behaviour of the new line versus the curve, the performance of the long end given ongoing debate around UK issuance skew, and whether upcoming supply repeats the demand pattern.
