How do gilt yields affect the annuity rate you can secure?
Insurers back annuity promises with long-dated government bonds, so the income they can offer moves with long gilt yields almost mechanically. That single relationship explains why annuity rates roughly doubled between 2021 and 2023 without any change in how the product works.
- The link: insurers match annuity liabilities with long gilts, so the yield sets the income.
- The direction: higher yields, higher annuity rates; lower yields, lower rates.
- The scale: the 2021-2023 move in yields transformed the income a given pot could buy.
- The consequence: the purchase date is permanent, so it locks in that day's yield for life.
01 The matching problem
An insurer selling a lifetime income takes on an obligation stretching thirty years or more, and it has to hold assets whose cash flows match. Long-dated gilts do exactly that: a known payment on a known date from an issuer that does not default in its own currency.
So the yield available on those gilts sets the income the insurer can promise. If a twenty-year gilt yields 4.5%, an insurer can offer meaningfully more income per £100,000 than when the same gilt yields 1%. Nothing about the customer or the product changed.
Insurers add corporate bonds and other matching assets to improve the yield, and they hold capital against the risk. That is why annuity rates are not identical to gilt yields — but the direction and most of the movement come from the gilt market.

02 Why rates moved so much
Long gilt yields spent the decade after the financial crisis at historic lows, and annuity rates went with them — which is the whole reason annuities acquired a reputation as poor value during that period. The reputation was accurate and it was about interest rates rather than about the product.
When yields rose sharply through 2022 and 2023, annuity rates rose in step, and the income a given pot could buy changed more in eighteen months than in the previous ten years. Retirees making the same decision two years apart faced completely different arithmetic.
The Bank of England's policy rate is the anchor for the short end, and expectations about it feed the long end alongside inflation expectations and gilt supply. Inflation expectations matter twice here, because they move the yield and they determine what the income will be worth.
Shows: how the income from a fixed pot changes as the annuity rate moves with yields. Ignores: insurer margins, the shape of the annuity, your health, tax and inflation.
On the defaults above, the worked example shows £17,500 a year. The same £250,000 buys £11,250 a year at 4.5% and £17,500 at 7% — a difference of £6,250 every year, for life.

03 What it means for your decision
Buying an annuity fixes that day's yield environment for the rest of your life, which is unusual among financial decisions and is the reason the timing feels consequential. It is also the reason phasing exists: buying in tranches across several years averages the yield you lock in, in the same way that regular investing averages a purchase price.
What it does not justify is waiting for a better rate with no plan. A yield forecast is a market prediction, and the cost of being wrong is measured in the income you did not receive. Phasing converts the timing question into a spreading question, which is answerable.
It also explains why deferring often looks attractive after a fall in yields and unattractive after a rise. The rate you are comparing against is itself a moving benchmark.

Annuities did not become good value in 2023 because insurers became generous. They became good value because long gilt yields quadrupled, and the product passed that straight through. Understanding that changes what you do with it: you stop reading annuity rates as a verdict on annuities and start reading them as a bond market quote. And once you see it that way, phasing the purchase across three or four years stops looking cautious and starts looking like the obvious way to avoid betting your retirement income on one particular Tuesday.
FAQ
Why did annuity rates rise so sharply?
Long gilt yields rose sharply through 2022 and 2023, and insurers back annuities with long gilts. The income a given pot could buy followed almost mechanically; nothing about the product changed.
Will rates fall again if the Bank of England cuts?
Policy rates anchor the short end, and long yields respond to expectations about inflation, future policy and gilt supply rather than to the current rate alone. The link is real but not one-for-one, which is why forecasting it is a market call.
Should I wait for higher yields before annuitising?
Waiting forgoes income you would have received, which a better rate takes years to recover. Buying in tranches across several years averages the yield you lock in and removes the need to forecast, which is usually the better answer than either buying all at once or waiting.
