Chancellor Rachel Reeves is set to unveil her spring economic forecast on Tuesday, amid mounting pressure from an alliance of think tanks advocating for a significant overhaul of the Office for Budget Responsibility (OBR). Their calls for reform come at a crucial juncture, as the Labour Party grapples with the aftermath of a disappointing byelection result against the Greens in Gorton and Denton. The think tanks argue that the current economic framework hinders long-term investment and exacerbates instability, hindering the UK’s path to recovery.
Calls for Reform Ahead of the Spring Forecast
A coalition comprising various think tanks, including the Labour-aligned Progress, the New Economics Foundation (NEF), Common Wealth, and the Women’s Budget Group, has emphasised the necessity for Reeves to reassess the OBR’s role. The groups contend that the existing framework contributes to short-termism and underinvestment, undermining the potential for sustainable economic growth. “It has become increasingly clear that our current framework is contributing to instability, short-termist underinvestment, and a lack of focus on long-term risks and opportunities,” they stated.
Louisa Dollimore, director of strategy at the Good Growth Foundation—which facilitated the coalition—asserted that the OBR functions as a “backseat driver with out-of-date maps,” obstructing essential long-term planning during a time when the UK’s economy requires robust investment and foresight.
Concerns Over Fiscal Management
The criticism of the OBR extends to its perceived inability to adequately incorporate the prospective benefits of government investment into its assessments. Economists have noted that the institution tends to issue pass-fail evaluations of the Chancellor’s fiscal rules, often leading to hasty policy reactions. This reactionary approach was highlighted by the significant £5 billion in welfare cuts enacted in last spring’s budget.

While Reeves has already taken steps to reform fiscal rules, notably allowing the Treasury to increase borrowing for investment purposes, the think tanks assert that a more thorough reform is essential. They argue that the OBR, originally established during an era defined by austerity under former Chancellor George Osborne, fails to account for the long-term value of investments in areas such as public health, housing, and infrastructure.
A Shift in Fiscal Strategy
Reeves has made notable adjustments to fiscal policies, including raising taxes to fund public services while permitting greater borrowing for investment. However, concerns persist among some Labour MPs about the party’s cautious stance on tax and expenditure, fearing it could stifle economic recovery.
During a recent Treasury select committee hearing, former OBR directors Richard Hughes and Robert Chote echoed these concerns, noting that successive governments have historically overspent. Hughes, who resigned last year after a premature release of OBR budget forecasts, warned that failure to account for potential economic shocks could result in escalating deficits and debt levels. “Most surprises that governments face tend to be bad ones, especially these days,” he remarked.
The Economic Landscape Ahead
As Reeves prepares to address the nation, she is expected to highlight signs of a modest economic recovery alongside Labour’s efforts to restore fiscal stability. The think tanks’ recommendations for OBR reform carry significant implications for the government’s approach to economic management and public investment strategy.

Why it Matters
The push for reforming the Office for Budget Responsibility underscores a broader debate about the UK’s economic future, particularly as the country seeks to navigate the complex landscape post-pandemic. By addressing the limitations of the current fiscal framework, the government could unlock the potential for sustained growth and resilience, ultimately shaping a more productive and equitable economy. As public investment becomes increasingly critical, the outcome of Reeves’ spring forecast and the subsequent actions taken could determine the trajectory of the UK’s economic recovery in the years to come.
