UK Gilts Attract Buyers as Investors Bet the 2022 Bond Crisis Still Disciplines Westminster

The UK gilt market has become a political warning system. Reuters reported that ten-year gilt yields recently jumped by the most in more than a year and reached their highest level since 2008, after Labour’s local election losses raised questions about Starmer’s leadership and opened a possible path for Manchester Mayor Andy Burnham to challenge him. Investors are concerned that a new leader could push for higher spending or looser fiscal rules, especially after Burnham previously argued that Britain needed to move beyond being “in hock to the bond markets.”

Yet some large asset managers see the selloff as an opportunity. AllianzGI is maintaining a bullish position favouring 30-year gilts against U.S. Treasuries, while Royal London has added to its gilt exposure because it views current yield levels as difficult to sustain over the long term. The basic investment logic is simple: if fiscal fears fade and yields fall, gilt prices rise. But the trade depends heavily on one assumption, that any Labour successor would remember how quickly markets punished unfunded fiscal expansion in 2022.

That memory is powerful because the 2022 crisis was not just a normal bond selloff. After the Truss government’s mini-budget shocked markets, long-dated gilts came under severe pressure, and the Bank of England had to step in with temporary purchases of long-dated government bonds to restore orderly market conditions. The Bank later explained that leveraged liability-driven investment funds faced collateral calls and could have been forced into gilt sales that would have created a vicious spiral of falling prices and rising yields.

This is why investors now talk about “bond vigilantes” as a real constraint on UK politics. The market is effectively telling any future government that fiscal ambition must be funded, credible, and clearly communicated. The OBR’s March 2026 outlook also matters in this context because it noted that the government has moved to having only one formal annual assessment of performance against fiscal rules at Budgets, while the spring forecast now provides broader analysis of public-finance risks rather than a full rule assessment. That puts even more emphasis on market confidence between fiscal events.

The bullish gilt case is therefore not based on a view that the UK’s problems have disappeared. Britain still faces weak growth, persistent inflation pressure, high borrowing costs, and political uncertainty. The argument is more tactical: yields already reflect a lot of bad news, and the 2022 crisis may have permanently changed how far UK politicians are willing to push against the bond market. If that assumption holds, gilts could reward patient buyers. If it fails, the UK could again face a painful feedback loop where political risk raises yields, higher yields shrink fiscal space, and shrinking fiscal space forces even harder budget choices.
