The unexpected departure of the Office for Budget Responsibility’s (OBR) chair, Richard Hughes, has triggered a period of uncertainty for the Treasury, with Chancellor Rachel Reeves now tasked with recruiting a successor capable of maintaining the body’s authority and independence.
Hughes stepped down following the premature release of Budget material—an incident attributed internally to a junior staff error. While the resignation adds immediate pressure, wider issues have long been simmering between the OBR and government over the assessment of economic policy.
Reeves must now identify a high-profile economist who can command market confidence, particularly as investors will scrutinise any move that hints at political interference. Yet ministers also face demands—from across the political spectrum—to reshape a system some critics view as limiting the power of elected governments.
A key frustration for the administration was Hughes’s stance on “pro-growth” measures. The OBR declined to positively score policies unless they delivered a measurable boost to national income. None met the 0.1% threshold, a decision that angered parts of government. Hughes consistently argued that forecasts must remain evidence-based and shielded from political pressure, a posture that was visible during both the Truss mini-Budget turmoil and more recent tensions.
The government has already set out structural changes. While the OBR will continue producing two major forecasts annually, ministers will formally respond only once, reducing the likelihood of mid-year policy adjustments. Hughes insisted this would not reduce transparency, though it raises questions about how surpluses or fiscal improvements might be handled ahead of elections.
Recent forecasts have also brought sensitive issues to the fore, including the long-term economic impact of artificial intelligence and the growing cost of special educational needs. Some ministers bristled at the latter, but supporters say it highlights the OBR’s ability to force uncomfortable policy discussions.
Hughes defended the body’s mandate, arguing that chancellors set targets and spending priorities, while the OBR simply provides independent assessments. He noted that governments retain full freedom to alter their own goals.
His planned appearance before the Treasury Select Committee was cancelled following his resignation. Observers say Hughes’s knowledge of the behind-the-scenes debates over fiscal outlooks could continue to cast a shadow as he moves into gardening leave.
Across five years, Hughes worked with five chancellors, aiming to bolster economic stability through consistency and transparency. His exit now opens the door for a new approach to the OBR—seen by some as a chance for reform, but also a potential risk to credibility if independence is weakened.
The coming appointment will not only shape Reeves’s relationship with markets, but also define how economic oversight functions in an era of political and fiscal strain.
