UK warned over ballooning debt costs and slower growth ahead of Budget

The Organisation for Economic Co‑operation and Development (OECD) cut its forecast for UK growth in 2025 to 1 percent, down from an earlier 1.1 percent estimate, citing higher energy prices driven by the Middle‑East conflict and the Russia‑Ukraine war. The downgrade places the United Kingdom among a group of nations whose growth outlooks have been trimmed, while the OECD simultaneously raised its short‑term outlook for 2024 to 1.1 percent from 0.9 percent, noting the economy’s unexpected resilience this year. At the same time, International Monetary Fund chief Kristalina Georgieva warned that spiralling borrowing costs are pushing debt levels “up like a staircase not to heaven,” urging governments, including Britain’s, to act swiftly to contain debt service expenses. Prime Minister Andy Burnham acknowledged that the country’s high borrowing leaves it “over‑exposed” to global shocks, reaffirming his earlier stance that Britain should be less dependent on bond‑market investors, a comment that previously unsettled markets.

The report highlights that the surge in crude‑oil prices has amplified fuel and energy costs, feeding global inflation and eroding household purchasing power, while also inflating the interest burden on government debt. An unexpected rise in UK borrowing in August added further pressure on Chancellor Jeremy Healey’s fiscal plans, as the cost of servicing debt is projected to reach levels not seen since the mid‑1980s. Economists such as Ruth Gregory of Capital Economics note that the UK’s current resilience stems largely from businesses’ stockpiles and households’ reduced savings, but warn this buffer is temporary and that the “drag” from energy prices will intensify, dampening growth next year. The OECD also warned of additional risks, including weaker returns on artificial‑intelligence investments, climate‑related supply shocks, and potential food‑price spikes from El Niño‑driven weather events, all of which could further strain the economy.

The fiscal strain is already influencing private sector decisions, with Ryanair’s chief executive Michael O’Leary announcing that ticket prices will rise “materially” next summer as the airline’s fuel bill is expected to jump by $1.5 billion to $7.5 billion. Meanwhile, Conservative shadow chancellor Andrew Griffith criticised the Labour government for seeking new taxes while paying the highest borrowing costs among G7 nations, urging tighter spending controls and greater public‑sector efficiency. Treasury chief Emma Reynolds defended the government’s approach, claiming it is providing families with breathing space and initiating long‑term reforms to generate jobs across all postcodes. As the UK balances the need to support households against the imperative to adhere to its self‑imposed fiscal rules and Labour’s manifesto commitments, the coming Budget will be pivotal in determining how the nation navigates the twin challenges of mounting debt costs and slower growth.
