US-UK Yield Gap Tracker 2026: Treasury-Gilt Spread, GBP Analysis & BoE-Fed Divergence
UK Gilts now yield more than US Treasuries — an unusual "Gilt premium" reflecting UK fiscal risk and sticky inflation. This tracker monitors the Treasury-Gilt spread, its velocity, regime transitions, and the structural forces behind the inverted yield relationship.
QUICK ANSWER · AS OF Apr 8, 2026
What is the US-UK 10Y yield gap in 2026?

Yield Gap Regime Map
Traditional regime — US yields above UK and gap expanding. Reflects stronger US growth or tighter Fed policy relative to BoE.
US yields still above UK but gap compressing. BoE tightening or Fed easing closing the differential.
Unusual "Gilt premium" — UK yields above US and gap expanding. Reflects UK fiscal risk, sticky inflation, or Gilt market stress.
UK yields above US but gap compressing. Gilt stress easing, BoE cuts expected, or UK fiscal concerns fading.
Current Regime Narrative
UK 10Y Gilt yields have surged above US Treasury yields — an unusual inversion of the traditional relationship. UK yields are elevated due to sticky inflation (CPI ~3.5%), fiscal concerns (high government borrowing), and BoE reluctance to cut rates as aggressively as the Fed. The -34bps gap (UK above US) is a significant departure from the 5-year average of +30bps (US above UK). This "Gilt premium" reflects UK-specific fiscal and inflation risks.
Historical frequency: 15% · Avg duration: 6 months
Yield Gap Drivers
UK CPI at ~3.5% is higher than US CPI (~2.8%). Sticky UK inflation keeps BoE rates elevated and pushes Gilt yields above Treasuries.
High UK government borrowing and debt-to-GDP (~100%) create a fiscal risk premium in Gilts. The 2022 mini-budget crisis demonstrated how quickly fiscal concerns can spike Gilt yields.
Fed cuts pull US yields lower, potentially widening the gap further (UK above US). But if BoE follows with cuts, the gap could narrow.
Markets expect BoE to cut rates in H2 2026 as UK growth slows. This would pull Gilt yields lower and narrow the gap.

The US-UK yield gap has inverted — UK Gilts now yield more than US Treasuries. This reflects UK-specific risks: sticky inflation (3.5% vs US 2.8%), high fiscal borrowing, and BoE reluctance to cut. The BoE bank rate at 4.25% vs Fed at 3.50-3.75% creates a 50-75bps policy rate gap favoring GBP carry, but the Gilt premium suggests the market is demanding compensation for UK fiscal risk.

Methodology
The US-UK Yield Gap Index (UKYG) measures structural stress in the Treasury-Gilt spread. The gap is negative because UK Gilt yields are above US Treasury yields:
- Gap Deviation (40%): |current_gap − avg_gap_5y| / 1.5 × 100, capped at 100.
- Gap Velocity (35%): |gap_30d_change| / 0.5 × 100, capped at 100.
- Extreme Signal (25%): |current_gap| / 3.0 × 100, capped at 100.
Signal thresholds: LOW <25, ELEVATED 25–49, HIGH 50–74, CRITICAL ≥75. v0.1-beta.
