Why are UK gilt yields rising in a slowing economy?
Gilt markets are sending an unusual signal.
Traditionally, when economic growth slows, government bond yields fall and prices rise. Investors seek safety, central banks cut interest rates and bonds benefit.
Today, that relationship has broken down. UK government bond (gilt) yields have risen even as the economic outlook has become more uncertain.
Understanding why matters, not just for bond investors, but for anyone allocating capital across asset classes.
A different macro backdrop
At a high level, gilt yields reflect three core drivers:-
Expectations for future interest rates
-
The path of inflation
-
The additional return investors demand for holding longer-term bonds (‘term premium’).
In the current environment, all three have moved higher.
The key catalyst has been a renewed rise in energy prices, which has pushed up inflation expectations. At the start of the year, markets expected UK inflation to fall back below the Bank of England’s 2% target - set by the government - paving the way for rate cuts. Instead, higher oil and gas prices have complicated that outlook.
This leaves policymakers in a difficult position. Inflation risks remain, yet growth is weakening. Markets have responded by pricing in a more cautious path for interest rates. That repricing has pushed gilt yields higher.

Why the UK stands out
While global bond markets have faced similar pressures, the UK has been particularly sensitive.
There are two main reasons:
1. Inflation credibility. The inflation shock of 2022 remains fresh in investors’ minds. UK inflation rose more sharply and persisted for longer than in many other developed markets.
As a result, when inflation risks re-emerge - for example through higher energy prices - gilt markets tend to react more aggressively.
2. Fiscal and political sensitivity. The UK’s fiscal position remains a key consideration for investors. Periods of political uncertainty have heightened scrutiny of government borrowing plans and fiscal discipline.
This sensitivity means that gilt yields can move more sharply than those in other markets when uncertainty rises. The experience of recent years has reinforced the importance of credibility and consistency in fiscal policy.
