PWLB Snapshot

Tenor Rate Chg
1y 5.44% +1bp
3y 5.72% unch
5y 5.88% -1bp
10y 6.23% -4bp
25y 6.70% -9bp
50y 6.41% -14bp

The curve bull-flattened, with the long end dropping sharply while the front end held steady or edged up.

What Moved

  • → Long end drops hard — 50y down 14bp, 40y down 12bp, 30y down 10bp; sharpest moves seen in decades.
  • → Belly and short end mixed — 10y down 4bp, 5y down 1bp, 1y actually up 1bp; clear flattening dynamic.
  • → Curve shape — pronounced bull flattening, with long-dated rates falling much faster than the front end.

Context

  • → UK retail sales (Aug) — MoM +0.50% (f'cast -0.20%, prev -0.50%), YoY +2.40% (f'cast 1.90%, prev 1.20%); both above expectations, but no evidence this drove the gilt rally.
  • → News flow — No major UK macro or BoE news; global headlines focus on Japan and oil, with little direct impact on gilts.
  • → Market context — The scale of the long-end move suggests a technical or flow-driven rally, not a direct response to today's UK data.

Calendar Events

Today's Releases

  • → Retail Sales MoM (Aug): +0.50% (forecast -0.20%, prev -0.50%) — upside surprise, but not reflected in rate direction.

⚑ Treasurer's Note — The PWLB curve has bull-flattened sharply, with the 50-year rate down 14bp and 25-year down 9bp at the AM reset. The most significant move is the long end, which has dropped to 6.41% for 50y and 6.70% for 25y. Short rates are little changed or slightly higher. If you are considering long-dated borrowing, this is a material shift to note ahead of the next reset.

Gilt Edge Advisor — still here when the long end actually moves and everyone suddenly cares about duration.
