Rates Spark: UK political risk closely tied to inflation outlook
Per the full note from ING , UK gilt markets remain acutely sensitive to inflation shocks, meaning any near-term Labour fiscal expansion would trigger an immediate repricing of sterling rates. The desk argues this is because the BoE has yet to return inflation to target, leaving markets pricing a terminal rate above 3.75%. With oil falling, the inflation outlook is set to soften next year, granting more fiscal leeway — but near-term spending plans remain the key risk. Consensus on GBP/USD for Dec-26 sits at 1.35, with a wide range from 1.24 (Citi) to 1.43 (BofA), reflecting deep uncertainty around the fiscal-inflation nexus.
What the desk is arguing
ING frames UK political risk as intrinsically tied to the inflation outlook, not sovereign risk. Any near-term fiscal expansion by Labour would delay the BoE's 2% target and force a hawkish repricing on the front end. The desk highlights that markets still price a terminal BoE rate near 4%, above the current bank rate of 3.75%, underscoring lingering inflation sensitivity.
Supporting this thesis, ING notes that when oil surged above $100, sterling rates repriced far more aggressively than EUR rates, revealing a structural vulnerability to inflation-inducing shocks. The recent decline in oil prices, however, should soften the inflation outlook next year, potentially giving Chancellor Burnham more leeway for spending further out.
The alternative read would be that markets overreact to UK fiscal noise and that a disinflationary environment in 2026 will allow the BoE to cut rates without triggering a gilt tantrum. ING implicitly rejects this, arguing near-term fiscal stimulus would test the BoE's credibility on inflation.

Key takeaways
- 01UK gilt yields are highly sensitive to any near-term fiscal expansion due to lingering inflation risks and a BoE yet to hit its 2% target.
- 02Falling oil prices should ease inflation pressure in 2026, potentially allowing more fiscal space later, but near-term spending remains a gilt-negative catalyst.
- 03Markets still price a terminal BoE rate of ~4%, above the current 3.75% bank rate, leaving room for a hawkish repricing if Labour announces near-term spending.
- 04GBP/USD consensus for Dec-26 is 1.35, with a bearish extreme of 1.24 (Citi) and bullish extreme of 1.43 (BofA), highlighting binary risk around the fiscal-inflation outlook.
Market implications
Watch GBP/USD for an immediate break lower if Labour announces any near-term spending plans above market expectations. The key level to monitor is the Dec-26 consensus of 1.35; a sustained break below could target the 1.24 Citi bear case. Also keep an eye on EUR/GBP, which would reflect the BoE vs ECB divergence if UK rates spike relative to EUR rates.
Risks to this view
A sharp decline in oil prices that accelerates disinflation would invalidate the hawkish tilt, allowing the BoE to cut rates and supporting gilt prices. Conversely, a spending announcement that is perceived as fiscally responsible (e.g. paired with tax increases) could be taken as positive by markets, reversing the adverse reaction. The biggest risk to the call is a clear BoE communication that looks through fiscal expansion as temporary, limiting the rate repricing.

The impact of spending further out in the future should be more muted. Meanwhile, US Treasury yields are showing a renewed appetite to test higher; we expect more of this Michiel Tukker and Padhraic Garvey, CFA Sterling rates are still very sensitive to any inflation-inducing shocks Sterling rates to stay sensitive to near term spending plans Inflation remains the biggest threat to gilts, but with oil coming down, Burnham might be given more leeway from markets further out in the future.
This is because the political risk in GBP rates is more about the UK’s inflation outlook than sovereign risk. If Labour manages to pull off a fiscal expansion in the near term, then the prospect of reaching the inflation target of 2% could be delayed again. But with oil falling in recent weeks, the inflation outlook should soften next year.
Unfortunately for Burnham, at the moment, sterling rates are still very sensitive to any inflation-inducing shocks. This might be explained by the fact that the Bank of England has not managed to return inflation to target yet. When oil moved well above $100, markets were very quick to price in a significant tightening cycle, much more so than for the ECB.
So any large spending initiatives in the near term could expect an immediate market reaction. Important to note is that a fiscal expansion while inflation is rising is treated differently by markets than during a disinflationary environment. Markets are still pricing in a terminal Bank of England rate around 4%, even above the current bank rate of 3.75%.
This should change next year, however, when we expect a more disinflationary environment. This means that the market impact of fiscal plans, such as the currently debated defence spending, depends on the timing of the spending. Near-term spending initiatives should push rates up more than spending further out into the future.
And just like that we're back at 4.45% for the 10yr UST US Treasuries had an excuse to test lower in yields on Tuesday as consumer confidence for June came in weaker than expected (91.2 vs reference at 100). But instead, the market narrative centred on the better-than-expected job openings for May (7.6 million vs 7.3 million anticipated). However, that misses a finer point.
It tells us that the bond market is not prepared to go with materially lower long-tenor yields. The 10yr Treasury yield has been trading in sub 4.4% territory in recent days, and looking for an excuse to test lower. It's actually had a few.
