UK gilt (government bond) markets are in a sharp sell-off on 1 September 2026, with yields rising to multi-year or multi-decade highs amid a global bond market move driven by renewed Middle East (Iran-related) tensions, higher oil prices, and reignited inflation fears.
Key yields (approximate levels as of early/mid-session 1 September)
- 10-year gilt: Around 5.23–5.25% (up ~7–11 basis points on the day), the highest since June 2008.
- 2-year: Around 4.51–4.59% (near recent highs).
- 20-year: Around 5.82%.
- 30-year: Around 5.89–5.90% (up ~10–12 bps), the highest since around March 1998.
Longer-dated gilts have been particularly hard-hit. Nearly all conventional gilts saw yields rise. The market was also catching up after the UK public holiday on Monday.
Drivers
- Escalating Middle East hostilities and higher oil prices (Brent rising) have revived concerns about inflation persistence and potential second-round effects.
- Broader global bond sell-off, with yields rising elsewhere (including Japan and the US).
- Markets pricing in roughly 30–32 basis points of Bank of England tightening by year-end (e.g., a November hike seen as likely in some pricing), despite the BoE holding Bank Rate at 3.75% in its July decision.
- Domestic factors include rising shop-price inflation and ongoing fiscal/borrowing concerns ahead of the Budget under the current government (references to PM Burnham and Chancellor Healey appear in coverage). Quantitative tightening (gilt sales from the Asset Purchase Facility) continues in the background.
Broader implications
Higher yields mean higher UK government borrowing costs. Gilt prices have fallen correspondingly (yields and prices move inversely). Some analysts note that elevated yields may already price in a fair amount of inflation and fiscal risk, potentially limiting further sharp moves, though the situation remains sensitive to oil prices, geopolitical developments, and upcoming BoE decisions (next meeting mid-September).
Overall, the gilt market is under clear pressure from external inflation risks and a shift toward higher-for-longer rate expectations, rather than purely domestic issues.
