UK government bonds — known as gilts — are offering yields that haven’t been seen in decades. Several gilts now pay over 4% to maturity, with some longer-dated issues exceeding 5.5%. That’s a far cry from the near-zero yields of the early 2020s. For anyone looking for predictable income or a place to park cash with a known return, these numbers naturally raise a question: is now the time to buy? Here’s what you actually need to know.
Gilts are essentially loans to the UK government. You lend money, and in return you receive fixed interest payments twice a year plus your original investment back at maturity. Because the UK government has never defaulted on a sterling bond, they’re considered one of the safest places to put money. But safety doesn’t mean simplicity. The relationship between yields, prices, interest rates, and inflation creates a more complicated picture than the headline numbers suggest. Alternative investments like gilts require understanding how they behave in different economic conditions.
What gilts offer and what the key terms actually mean
Two yield measures matter here. The running yield is simply the annual coupon divided by the current price. The yield to maturity (YTM) is more useful — it accounts for both the coupon payments and any capital gain or loss if you hold the bond until it matures. For example, the UK Treasury 4.000% 2029 trades around 99.15, giving a running yield of 4.03% but a YTM of 4.31%. The difference comes from the fact you’ll get £100 back at maturity for a bond you bought at 99.15.
What I tend to notice is that many people focus on the coupon rate without checking the YTM. A gilt with a low coupon trading well below £100 can actually offer a better total return than a higher-coupon bond trading near par. The CGT exemption makes that price appreciation even more valuable.
Why gilt yields matter for your portfolio right now
The Bank of England has already cut rates from 4.75% to 3.75%, and Goldman Sachs Research forecasts further cuts that could bring the policy rate down to 3% by summer 2026. When interest rates fall, existing bonds with higher coupons become more attractive, pushing their prices up. That dynamic is the main reason short-term gilts have performed well recently.
But the picture isn’t uniform across maturities. Longer-dated gilts — those with 20 or 30 years until maturity — have been far more volatile. The 30-year gilt yield surged to levels not seen since the late 1990s during 2025, driven by inflation concerns, increased government borrowing, and global bond market turbulence. The UK’s debt-to-GDP ratio is nearing 100%, and the Bank of England’s quantitative tightening programme adds to supply pressure.
Morningstar’s UK Gilt Bond Index still rose 5% in 2025, but that masks significant swings. Yields spiked in January, again in September, and then ahead of the Autumn Budget. For someone who bought a long-dated gilt in early 2025 and needed to sell mid-year, the experience would have been unpleasant. For someone who held to maturity, the outcome was always known.
Political risk also plays a role. Morningstar’s international economist Grant Slade notes that the government enters 2026 in better fiscal shape than it started 2025, with improved headroom after the Autumn Budget. But a revived leadership challenge to Prime Minister Keir Starmer could be another flashpoint for bond markets, potentially leading to a new chancellor with less commitment to fiscal consolidation. That risk may already be partially priced in, but it’s worth weighing.
Where people get gilt investing wrong
Confusing yield with total return
A 5% yield sounds straightforward, but if you buy a gilt at a premium price and hold it to maturity, your actual return will be lower than the coupon suggests. Conversely, buying a low-coupon gilt at a deep discount — like the UK Treasury 0.125% 2028 trading at 93.75 — means most of your return comes from the price rising back to £100, which is CGT-free. The yield to maturity captures this, but many investors look only at the running yield.
Ignoring duration risk on long-dated gilts
The UK Treasury 0.500% 2050 trades at 67.16. That means if you bought it at issue for £100, you’ve lost nearly a third of your capital on paper. These bonds were issued when yields were near zero; as rates climbed, their prices collapsed. The extra yield for locking money up for 30 years is currently modest relative to the volatility. If rates rise again, those prices could fall further. A bond investing guide for beginners can help clarify how duration affects price sensitivity.
Overlooking inflation risk
A fixed coupon of 4% loses purchasing power if inflation runs above that level. UK inflation is currently around 3.8%, almost double the Bank of England’s 2% target. If inflation stays sticky, the real return on a gilt could be near zero or negative. Index-linked gilts exist to address this, but they trade differently and have their own complexities.
Assuming all gilts are the same
A 1-year gilt and a 30-year gilt behave like completely different assets. The short end is driven by expectations for Bank of England rate decisions. The long end is driven by inflation outlook, government borrowing plans, and global investor sentiment. Treating them as interchangeable is a mistake.
| Gilt | Maturity | Yield to Maturity | Price Sensitivity |
|---|---|---|---|
| UK Treasury 4.125% 2027 | 2027 | 4.06% | Low |
| UK Treasury 4.250% 2034 | 2034 | 4.72% | Moderate |
| UK Treasury 4.750% 2043 | 2043 | 5.39% | High |
| UK Treasury 4.375% 2054 | 2054 | 5.56% | Very High |
How to approach gilts based on your situation
Matching a known future expense
If you know you’ll need a specific amount of money in a specific year — school fees, a house deposit, retirement spending — buying a gilt that matures in that year gives you a known outcome. You don’t have to worry about price fluctuations along the way because you’re holding to maturity. The UK Treasury 4.125% 2027, yielding 4.06%, is an example of a short-dated option with minimal price sensitivity. You buy it, collect the coupons, and get your capital back in 2027.
Building a bond ladder
Instead of putting everything into one maturity, you spread your money across several. For example, you might buy gilts maturing in 2027, 2029, and 2034. As each one matures, you reinvest the proceeds into a new longer-dated gilt. This smooths out interest rate changes over time and provides regular liquidity. It’s a strategy that works well for income-focused investors who don’t need all their money back at once.
Income from higher-coupon gilts
If your goal is regular income rather than capital growth, higher-coupon gilts like the UK Treasury 4.750% 2043 pay significant interest twice a year. The trade-off is that these bonds trade closer to par and have less price appreciation potential. They also carry more interest rate risk. A finance advice service can help you model how different coupon rates affect your income stream.
What 2026 could bring
Goldman Sachs forecasts 10-year gilt yields falling to 4% by the end of 2026, assuming the Bank of England continues cutting rates. Morningstar’s outlook is cautiously positive but flags risks around increased bond supply from government borrowing and Bank of England gilt sales. The Autumn Budget 2026 and May local elections could introduce political volatility. If you’re buying now, the question isn’t just whether yields are attractive — it’s whether you can hold through the inevitable price swings.

Gilts can play a role, but timing isn’t everything
Yields above 4% on government-backed debt are genuinely attractive by recent historical standards. But the decision to buy gilts depends more on your time horizon and goals than on whether yields might go higher or lower. If you need money in 2027, a gilt maturing that year gives you certainty no savings account can match. If you’re investing for 20 years, the extra yield from long-dated gilts comes with real volatility risk. The best approach is to match the bond to the purpose, not chase the highest yield.
