Gilt trip

UK government bond yields are rising again.

That means gilt prices are falling, because bond prices and yields move in opposite directions. When investors think the risk of loaning money to the government is increasing they will demand a higher return.

There are a few reasons for that. Inflation is still sticky, which makes future interest rate cuts less certain. If markets think the Bank of England will have to keep rates higher for longer, gilt yields usually rise too.

Westminster wobble

Labour’s poor local election results have created more uncertainty around the government. Markets are now watching to see whether political pressure – and a potential leadership contest – leads to looser spending, more borrowing, or a weaker commitment to fiscal rules. At the time of writing, Wednesday 13 May, no contest as of yet. 

This is not another mini-Budget. But the UK is in a tight spot. Borrowing is sky high, debt interest costs are expensive, and growth is anaemic. Against this backdrop, investors are more sensitive to anything that makes the public finances look less stable.

So, markets are asking the UK government to pay more to borrow. While uncomfortable for the Treasury, this can create an opportunity for investors. When gilt prices fall, new buyers can lock in higher yields if the maturity on a bond matches their investment horizon. Freetrade data shows retail investors have been responding to that. The value of gilt buy orders rose 193% between January and April 2026, and May is already pacing higher than April.

Gilt rush

For some investors, gilts can be useful because they are backed by the UK government and have a known maturity date. If you buy a gilt and hold it to maturity, you know (with a decent degree of certainty) what payments you are due to receive, assuming the government meets its obligations. It’s worth noting the UK has never technically defaulted on a gilt issued during peacetime. Not yet, that is. 

They can also have tax advantages. Gilt interest is taxable, but capital gains on individual gilts are generally free from capital gains tax. That is why some investors look at low-coupon gilts trading below their final repayment value.

Fine print

But gilts are not risk-free. If yields keep rising after you buy, the price of your gilt will usually fall. That matters if you need to sell before maturity. Longer-dated gilts are especially sensitive to yield moves, so they can be much more volatile than shorter-dated ones.

Inflation matters, too. A gilt may pay back exactly what it promised, but that money could be worth less in real terms if prices keep rising.

Higher gilt yields may be tempting, especially after years of low returns on government bonds. But they are not free money.
