The UK Government bond or ‘gilt’ market is once again under pressure. In recent weeks, yields on long-dated gilts have risen sharply, with the 30-year gilt yield reaching above 5.61% (at the time of writing).
That level has not been seen since 1998 and represents a significant increase in borrowing costs for the Government. The 10-year gilt, among other durations, has also been caught up in the move, trading higher than 4.76% at times.
Rising gilt yields matter far beyond the world of professional investors. They have implications for pensions, mortgages, savings, and the fiscal outlook of the country itself.
What is striking about this latest surge is that it comes just as the Bank of England has cut its base rate. At its most recent meeting, the Bank reduced rates by a quarter of a percentage point, bringing the base rate down to 4%.
In theory, such a move should reduce borrowing costs across the economy. Lower interest rates generally filter through to cheaper debt, making gilt yields fall.
Yet the opposite is happening—evidencing a worrying disconnection between monetary policy and bond markets.
Why yields are rising despite a rate cut
There are several reasons why gilt yields are rising even as the central bank is easing policy. First, although the Bank of England delivered a rate cut, it did so with what has been described as a “hawkish” tone.
The cut was framed as limited and conditional, with policymakers highlighting the persistence of inflation. This, alongside higher-than-expected inflation, has led markets to conclude that the path of rates will not move steadily downward but instead may remain elevated for some time. That has supported yields rather than pushing them down.
Second, demand for long-dated gilts has structurally weakened. For many years, defined benefit (DB) pension schemes were reliable buyers of 30-year gilts, using them to match their long-term liabilities.
As these schemes have closed to new members and increasingly wound down, their need to hold such gilts has declined. That has left a gap in demand at the longer end of the market, making yields more sensitive to supply and investor sentiment.
Finally, the fiscal picture is also increasing yields. With the Chancellor preparing her Autumn Budget, markets are well aware that the UK Government faces heavy borrowing requirements—and this is making the price of that activity higher.
Financing that debt in a market where demand is thinner means investors are demanding higher yields to absorb the supply. For a government already facing tight fiscal conditions, higher long-term yields compound the challenge.
Implications for investors
The implications of higher gilt yields are complex and sometimes contradictory. For those approaching retirement, rising long-dated yields have actually provided some good news.
Annuity rates, which move in line with gilt yields, have improved substantially. A 65-year-old with a £100,000 pension pot can now secure an annual income from an annuity that is among the most generous available in decades. For pensioners seeking certainty and guaranteed income, this represents a rare bright spot.
For other investors, the picture is less positive. Anyone holding long-dated gilt funds will be seeing losses as bond prices fall. Older bonds with lower coupons lose value as yields rise, and these paper losses can be significant.
Investors who bought into gilts when yields were lower may now be nursing declines in the capital value of their holdings. While long-term investors might eventually be compensated by higher future returns, the adjustment is painful in the short run.
The ripple effects extend into the housing market. Mortgage lenders price fixed-rate products partly by reference to gilt yields, particularly at the five- and 10-year maturities.
As those yields climb, fixed-rate mortgage deals become more expensive. For households hoping a Bank of England rate cut would ease the cost of borrowing, the reality may prove disappointing. Rising long-term yields could hold mortgage rates higher than expected, keeping pressure on homeowners.
On a macroeconomic level, the Government itself faces higher borrowing costs. Each rise in gilt yields increases the interest burden on newly issued debt. With the debt-to-GDP ratio already high, elevated borrowing costs could constrain fiscal policy, forcing tough decisions on taxation and spending.
This dynamic creates a feedback loop where fiscal and monetary policy interact in unpredictable ways, unsettling markets further.
Consider finances carefully before reacting
The current gilt market turmoil illustrates how financial conditions are shaped by a web of interacting factors: central bank decisions, inflation expectations, structural changes in demand, and the Government’s fiscal stance.
It is tempting for savers and investors to make swift decisions in reaction to headlines. Yet rising yields can be both a risk and an opportunity, depending on individual circumstances.
For some, the rise in long-dated yields makes annuities far more attractive than they were only a few years ago. For others—especially those with significant holdings in bond funds—the picture looks more challenging.
Meanwhile, anyone with a mortgage or considering refinancing needs to be alert to the fact that gilt yields can push borrowing costs in directions that appear to contradict central bank policy.
In such an environment, it is vital to take a step back. Personal finances are too important to be guided solely by market speculation or news cycles. Before making decisions on pensions, investments, or borrowing, it is wise to consider your long-term goals and risk tolerance.
Speaking to a regulated financial planner can provide tailored guidance that takes account of your situation, rather than relying on ever-changing market commentary.
The turbulence in the gilt market is a reminder that expert advice can help you navigate uncertainty with a clear plan.
