Recent rate movements
The gilts yield curve shape, measured by the 2Y–30Y spread (Spread Change = 30Y change − 2Y change), has moved in different directions across the three periods.
- Past day: Spread Change = (-0.97) − (-0.79) = -0.18bps, a FLATTENING move. Yields fell across the curve, with the 30Y (-0.97bps) declining slightly more than the 2Y (-0.79bps). The move is marginal.
- Past month: Spread Change = (-1.81) − (-3.02) = +1.20bps, a STEEPENING move. The 2Y fell by 3.02bps while the 30Y fell by 1.81bps, so the spread widened.
- Past year: Spread Change = (+53.18) − (+102.19) = -49.01bps, a FLATTENING move. Yields rose at both ends, but the 2Y increased by 102.19bps compared with 53.18bps for the 30Y.
Over the past year, the curve flattened materially because short-dated yields rose far more than long-dated yields, which is consistent with a repricing of near-term interest rate expectations rather than a uniform shift in the curve. The past month steepening reflects the opposite dynamic, with short-end yields falling more than long-end yields, while the past day flattening was too small to be economically meaningful. Taken together, the dominant verified trend is flattening, driven by the year-long move, with the one-month steepening being a reversal of part of that dynamic. The data reflects the direction of market pricing only and does not, on its own, establish the underlying causes of these changes.
Spread to the fitted curve
On 2026-10-14, the 0 3/8% Treasury Gilt 2026 (T26A, maturing 2026-10-22) showed a spread to the interpolated curve yield of -145.3 bps. This is well below its typical trading band of roughly -64.6 to +25.4 bps over the lookback period, and the bond's yield sits far beneath the yield implied by the surrounding curve.
The move was abrupt. Over the past day, the spread fell from about -25.4 bps to -145.3 bps, a decline of roughly 120 bps. Over the past month, it moved from about -4.7 bps to the current level. Over the past year, it has declined from about +7.1 bps to -145.3 bps. Before this point, the series had mostly traded within a range of about -40 to +3 bps, with only a few isolated readings outside it.
The implication is that T26A is trading rich relative to the curve, meaning its price is high and its yield low compared with comparable gilts. Because the bond has only about eight days to maturity, its yield is measured over a very short horizon, and small price changes can produce large swings in spread. The curve interpolation may also be less representative for a bond this close to redemption. The data alone does not establish the cause of the dislocation, so the figure should be treated as a statistically significant outlier that warrants monitoring rather than a signal of a broader curve shift.
