UK borrowing costs are on the rise yet again as markets react to chancellor Rachel Reeves's proposal to increase government borrowing by £32bn a year. This morning, yields on two-year and 10-year gilts rose by approximately three basis points, marking the tenth consecutive day of increases for the two-year bond – a streak not seen since 2006.
In early trading, UK bond yields reached their highest levels of the year, with the benchmark 10-year gilt yield hitting 4.526% in global trading. This level matched Thursday’s peak following Reeves’s budget statement, which has led investors to anticipate a slower pace of interest rate cuts from the Bank of England. Since then, yields have slightly retreated to 4.456%.
The bond market has been under scrutiny since Reeves's budget announcement, which included significant borrowing alongside tax increases of about £40bn. However, while there has been a noticeable reaction in the market for UK government bonds, also known as gilts, it has not so far been comparable to the turmoil following the mini-budget of Liz Truss and Kwasi Kwarteng in 2022.

This Friday, Moody’s released its budget analysis, where it warned about the potential risks associated with Reeves's fiscal plans, describing the increased borrowing as an “additional challenge” to managing the UK's public finances.
The rating agency said that the higher borrowing could elevate the cost of issuing debt, especially given that Reeves has revised the UK’s fiscal rules, leaving limited room for error in the face of unexpected economic shocks.
Moody’s noted that while the budget aims to stimulate day-to-day spending and government investment, it does little to enhance UK economic growth projections, which are expected to average only 1.7% from 2025 to 2027. The agency pointed out that structural issues, such as rising labour market inactivity and stagnant productivity, need to be addressed for sustained growth.
In response to the recent sell-off in gilts, which drove borrowing costs to their highest levels this year, Reeves doubled down on the government’s commitment to economic and fiscal stability. She said in a Bloomberg TV interview that robust fiscal rules have been established, promising significant fiscal consolidation.

Moody’s further cautioned that the market remains sensitive to any missteps in UK policy, a sentiment echoed in light of past fiscal disruptions. They noted that frequent changes to the UK’s fiscal framework have undermined its effectiveness as a credible anchor for policy. Nonetheless, Reeves’s shift to a stricter three-year timeline for meeting her revised fiscal targets has been seen as a step towards reinforcing credibility in her approach.
Matthew Ryan, head of market strategy at global financial services firm Ebury, said: “While Reeves has claimed that investment by the government while spur UK growth and restore stability to the economy, markets are clearly sceptical.
"Bond markets have been spooked by the increased borrowing – the 10-year gilt yield has leapt to a near one-year high 4.5%, 30 basis points up for the week, and around the levels following the Truss mini-budget sell-off in September 2022. Markets are clearly concerned that Labour’s plans for massive borrowing will push up bond issuance and keep rates higher for longer, raising mortgage rates and weighing on UK growth.

In her latest autumn statement, Reeves outlined her “clear economic plan”, asserting it aims to reduce debt while balancing the current budget within three years and delivering necessary investments to foster growth.
The UK’s chief secretary to the Treasury, Darren Jones, has said that the UK is seeing a normal market response to the budget, after the “PTSD” [post traumatic stress disorder] from the chaos following Truss and Kwarteng’s 2022 “mini-budget”.
He told Sky News: “There’s a lot of new information about the economy and the nation’s finances presented to parliament, and it’s normal for markets to respond.
“I think we’ve all got PTSD from Liz Truss and just let’s compare the two different scenarios, because they’re very, very different: So, under Liz Truss, as we saw, they sacked permanent secretary, they ignored the independent Office for Budget Responsibility.
“They announced £45bn of unfunded tax cuts and said they were only just getting started. And then the market went mad and we all know what happened. Completely different in contrast to now.”
