A gilt yield is an interest rate implied by the market price and promised cash flows of UK government debt. When investors say “the 10-year gilt yield rose”, they mean that the return available on government borrowing around that maturity has increased as bond prices and expectations have changed.
Gilt yields matter far beyond the government bond market. They are part of the sterling economy’s reference-rate structure, influencing mortgage pricing, corporate borrowing, pension liabilities and the discount rates investors use to value future cash flows.
What is a gilt?
A conventional gilt is a UK government bond. The government promises a fixed coupon payment every six months and repayment of principal at maturity. An index-linked gilt adjusts its coupon and principal for inflation according to its terms.
The Debt Management Office issues gilts to finance government borrowing and manages the stock. Once issued, most gilts trade in a secondary market, so their price changes continuously. The coupon printed on the bond does not change, but the yield available to a buyer changes as the market price moves.
Why bond prices and yields move in opposite directions
Suppose a bond promises fixed cash payments. If its market price falls while those promised payments stay the same, a new buyer is paying less for the same stream of cash and the implied return rises. If the price rises, the implied return falls. That inverse price-yield relationship is the basic mechanism behind daily gilt-market moves.
A bond’s quoted redemption yield is not the same thing as its coupon. It is a calculation that reflects the price paid, coupons received and redemption value. The Bank of England also estimates zero-coupon yield curves from gilt prices, which let analysts compare interest rates at different maturities on a consistent basis.
What does the 2-year gilt yield tell you?
Shorter-dated gilt yields are especially sensitive to expectations for Bank Rate over the next few years. If markets conclude that the Bank of England will need to keep policy tighter than previously expected, short gilt yields will usually rise. If a faster easing cycle becomes more likely, they can fall.
That does not make the 2-year yield a pure forecast of Bank Rate. Bond yields also contain risk and liquidity premia, and the exact bond being quoted has its own cash-flow structure. But the short end of the gilt curve is closely linked to monetary-policy expectations.
What does the 10-year gilt yield tell you?
A 10-year yield reaches much further beyond the next MPC meeting. It reflects expected future short rates, inflation compensation and term premia: the extra return investors may demand for committing capital to a longer maturity and bearing uncertainty about inflation and rates.
Fiscal conditions can matter too. The government’s expected borrowing and issuance affect the amount of duration the market needs to absorb, while perceptions of fiscal credibility can change the risk premium investors require. It is therefore too simplistic to read every 10-year move as “markets expect the Bank to raise rates”.
Why can the yield curve invert?
The yield curve plots interest rates across maturities. Normally, longer maturities often yield more than shorter ones because investors demand compensation for tying up money for longer. But the curve can invert, with short rates above long rates, when current monetary policy is tight and markets expect rates or inflation to be lower in the future.
An inverted curve is sometimes treated as a recession signal because it has preceded downturns in several economies. It is better understood as one market signal among many. The shape of the curve reflects expectations and premia, not a mechanical recession timer.
How gilt yields affect mortgages
Fixed UK mortgage rates are not priced directly from the 10-year gilt. Banks fund and hedge mortgages through a wider set of markets, especially sterling swaps, and add funding costs, capital costs, credit risk and margin. But gilt and swap curves respond to many of the same underlying expectations about inflation and monetary policy.
That is why mortgage rates can move before Bank Rate changes. If markets reprice the expected path of interest rates, wholesale rates can change immediately. For the household side, see whether UK mortgage rates are going down.
How gilt yields affect equities and companies
Higher risk-free yields raise the discount rate applied to future corporate cash flows, all else equal. That can weigh more heavily on assets whose expected profits sit far in the future. Higher gilt yields can also raise companies’ refinancing costs and change the relative attraction of bonds versus equities.
The effect is not uniform. Banks, insurers, utilities, housebuilders and highly leveraged companies each have different sensitivities. A yield move driven by stronger real growth is also a different economic signal from the same-sized move driven by an inflation shock or fiscal risk.
Where to find official UK gilt-yield data
The Bank of England publishes estimated UK government nominal, real and implied-inflation yield curves on a daily basis. The Debt Management Office publishes gilt prices, historical yields, issuance data, the gilts in issue and distribution of holdings. These are better primary sources than a static number copied into an explainer that will be stale tomorrow.
For the government balance-sheet context, see what the UK national debt is and who owns it. For the policy rate that anchors the short end of sterling markets, see the Bank of England rate outlook. For inflation, see the UK inflation outlook.
