Overview
- UK CPI came in at 3.8% for September, below the 4% expected by markets and the Bank of England.
- Benchmark gilt yields fell to 11‑month lows, with 10‑year yields near 4.38–4.4% and two‑year around 3.76–3.78%, reducing projected debt‑service costs.
- Bloomberg Economics estimates the Treasury could save up to about £4.5bn if the OBR’s 10‑working‑day market window captures current pricing, though the watchdog has not disclosed the timing.
- Reeves still faces a roughly £30–35bn fiscal gap as annual debt interest tops £100bn and inflation‑linked payments on index‑linked gilts are estimated around £28.5bn this year.
- The UK’s heavy reliance on index‑linked debt, about a quarter of outstanding gilts versus roughly a tenth in the US and France, magnifies the fiscal impact of inflation surprises as analysts flag higher odds of a BoE rate cut this year.
