The gilts yield curve has exhibited varying dynamics across the periods under review, with spread changes revealing distinct shape shifts. Over the past day, the spread change was +3.04bps (30Y change of +0.12bps minus 2Y change of -2.91bps), indicating a steepening move driven primarily by a decline in short-end yields. Over the past month, the spread change was +1.89bps (30Y change of +6.88bps minus 2Y change of +4.99bps), also signalling steepening, though here both ends rose with the long end outpacing the short end. Over the past year, the spread change was -23.98bps (30Y change of +27.78bps minus 2Y change of +51.76bps), confirming a pronounced flattening as short-end yields rose substantially more than long-end yields.

These verified movements carry distinct economic implications. Past day steepening, concentrated in a short-end yield decline, is consistent with near-term repricing of monetary policy expectations at the front of the curve. Past month steepening, with gains across all tenors but greater increases at the long end, may reflect shifting term premia or evolving long-term growth and inflation expectations. Past year flattening, characterised by a sharp rise in short-term yields relative to long-term yields, is typically associated with tighter monetary policy conditions, as central bank rate expectations exert greater upward pressure on the front end of the curve than on longer-dated instruments. This divergence between the short-term steepening signals and the longer-term flattening trend underscores the importance of distinguishing between near-term market repricing and the cumulative effect of monetary policy over a full year, without drawing conclusions from intermediate maturities such as 5Y or 10Y, which were not used in the spread calculations above.
