Analysis of the gilts yield curve reveals varying degrees of shape change across the observed periods, calculated as the spread change between the 30Y and 2Y tenors.

• Past day: Spread Change = (+1.60) - (+2.33) = -0.73bps, indicating a marginal flattening. All tenors rose in tandem, with short-end yields (2Y: +2.33bps) rising slightly faster than the long-end (30Y: +1.60bps), suggesting a broadly parallel upward shift with minimal curve distortion.
• Past month: Spread Change = (+6.07) - (+5.85) = +0.22bps, representing a negligible steepening. The 2Y yield rose 5.85bps while the 30Y rose 6.07bps, indicating the curve has been largely stable in shape despite intermediate tenors (5Y) showing a slight decline.
• Past year: Spread Change = (+31.80) - (+58.55) = -26.75bps, confirming a pronounced flattening. The short end has risen substantially more (2Y: +58.55bps) than the long end (30Y: +31.80bps), compressing the spread significantly over this period.

These shape changes carry distinct economic implications. The pronounced flattening observed over the past year is consistent with tighter monetary policy conditions, as short-term yields have risen more sharply than long-term yields, reflecting elevated policy rates alongside more moderate long-term inflation or growth expectations. In contrast, the near-parallel shift seen over the past month suggests yields across the curve have moved together, with no meaningful change in relative short versus long-term rate expectations. The slight flattening recorded over the past day is too marginal to indicate any shift in underlying economic expectations and likely reflects short-term market noise rather than a structural change in the curve's shape.
