Decision Summary
Overall outcome based on all metrics
✓ UK Gilts (for EUR-based investors) wins
For EUR-based investors, UK Gilts offer a better risk-adjusted opportunity than US Treasuries in 2026 when currency hedging costs are included. The high cost of hedging USD exposure (approximately 1,5-2,5% per year) eliminates most of the US nominal yield advantage. Unhedged US Treasuries provide higher real yields but introduce significant USD/EUR currency risk. For USD-based investors, US Treasuries remain the default choice. superior liquidity and marginally higher real yield.

🧠 Analysis
USD Hedging Cost Erodes Most of the US Treasury Yield Advantage for EUR-Based Investors
Key Evidence
- Hedging USD back to EUR costs approximately 1,5-2,5% per year in cross-currency basis swaps
- A US 10Y Treasury yielding 4,4% becomes approximately 1,9-2,9% after EUR hedge cost
- UK 10Y Gilt at 4,5% hedged back to EUR costs approximately 0,3-0,8%. net yield approximately 3,7-4,2%
- EUR-based investors often find hedged Gilt yield superior to hedged Treasury yield by approximately 100bps
What This Means
The US-UK yield comparison must include currency hedging costs for EUR-based investors. The headline yield comparison shows US and UK broadly similar. After EUR hedging costs, UK Gilts deliver materially better net yields for EUR-based institutional and private investors. This is why European institutional allocators often overweight UK Gilts relative to US Treasuries in hedged fixed income portfolios.

UK Offers 50-Year Gilts. The Longest Duration Sovereign Instrument in Major Markets
Key Evidence
- UK regularly issues 50-year Gilts. one of only a few sovereigns to offer this tenor
- The 50-year Gilt provides duration of approximately 35-40 years. essential for insurance companies and pension funds matching long liabilities
- US does not issue bonds beyond 30-year tenors in normal market conditions
- Index-linked Gilts (ILGs) provide inflation protection with long duration. popular for liability-driven investment (LDI) strategies
What This Means
UK Gilts provide unique duration capabilities for institutional investors managing long-dated liabilities. Life insurance companies and defined benefit pension funds with liabilities extending 40-50 years use UK 50-year Gilts specifically for liability-driven investment matching. US Treasuries (maximum 30 years) cannot serve this function. For liability-driven allocation, UK Gilts have no direct US equivalent.

❓ Frequently Asked Questions
Both are very high credit quality sovereign bonds with minimal default risk. US Treasuries lost their AAA rating from S&P in 2023 (now AA+) but retain it from Moody's (Aaa). UK Gilts are rated AA/Aa2. The practical difference in credit risk is extremely small. both are considered risk-free assets for most portfolio allocation purposes. The primary risks are interest rate risk (price sensitivity to yield changes) and currency risk (for investors not in USD or GBP).
European retail investors can access US Treasuries through ETFs listed on European exchanges (e.g., iShares $ Treasury Bond ETF, Xtrackers US Treasuries ETF). These are denominated in USD but traded on Euronext or Deutsche Börse. EUR-denominated Gilt ETFs are similarly available. Institutional investors use direct bond purchases, repo markets and derivative instruments. Currency-hedged versions of these ETFs are available for investors who want US yields without USD exposure.
Both UK Index-linked Gilts (ILGs) and US Treasury Inflation-Protected Securities (TIPS) provide inflation protection. the principal adjusts with the relevant inflation index.
