MPs Defend UK Economic Watchdog Against Critics

Published: 23 September 2026. The English Chronicle Desk. The English Chronicle Online.

Members of the UK Parliament’s Treasury Committee have rejected calls for fundamental reform of the Office for Budget Responsibility, arguing that criticism of the independent economic watchdog should not become a way of blaming it for difficult decisions created by the country’s tight public finances.

In a report published on Wednesday, the committee said policymakers should resist attempts to hold the Office for Budget Responsibility, commonly known as the OBR, responsible for difficult choices involving taxation and government spending. The MPs argued that the organisation’s role is to provide independent economic and fiscal analysis rather than determine the political decisions ultimately taken by ministers.

The committee’s inquiry examined the OBR’s role 15 years after its establishment and considered criticisms of its forecasting record, its influence over government policy and possible changes to its responsibilities. After considering evidence from economists and other experts, MPs rejected what they described as calls for fundamental changes to the watchdog’s position or independence.

At the same time, the committee recommended expanding the range of forecasts produced by the OBR. It said the government should consider asking the organisation to introduce an additional 10-year economic forecast alongside its existing five-year forecast and longer-term fiscal analysis.

The proposed 10-year forecast would not replace the existing five-year assessment used for the government’s fiscal rules. Instead, it would provide policymakers with additional information about the possible longer-term consequences of economic and fiscal decisions. The committee acknowledged that forecasts become increasingly uncertain as the time horizon becomes longer.

The recommendation reflects concerns among MPs that British economic policymaking can become heavily focused on relatively short periods. A longer forecast could, in the committee’s view, help policymakers examine the potential effects of investment and other decisions that may take several years to produce measurable economic results.

The committee also called for Parliament to devote specific time to discussing the OBR’s annual Fiscal Risks and Sustainability report. That assessment considers the long-term pressures facing Britain’s public finances and examines risks that could affect government borrowing, spending and debt over several decades.

Dame Meg Hillier, chair of the Treasury Committee, rejected descriptions of the OBR as an institution that exercises excessive control over ministers and Treasury officials. She argued that the importance of the OBR’s forecasts increases when the government has very limited room for manoeuvre under its fiscal rules.

According to Hillier, the constraints facing ministers are primarily a consequence of the government’s fiscal position and the rules it has chosen to operate under, rather than evidence that the OBR has exceeded its responsibilities. She also said that the independent role of the organisation should be protected as part of Britain’s economic decision-making framework.

The OBR was established in 2010 under then Chancellor George Osborne. Its central purpose is to provide independent forecasts for the economy and public finances and to assess the effects of government tax and spending policies.

Since its creation, however, the organisation has faced criticism from different parts of the political spectrum. Some critics have questioned whether its forecasts have accurately captured the effects of government policies or changes in economic conditions.

Economists giving evidence to the Treasury Committee raised a different concern. Professor Jo Michell of the University of the West of England and Dr Robert Calvert Jump of the University of Greenwich argued that the OBR’s estimates of fiscal headroom had acquired substantial influence over government spending decisions.

Fiscal headroom refers broadly to the amount of room available to a government under its fiscal rules before it would breach its stated targets. Because governments frequently use these measures when preparing budgets and assessing tax or spending changes, relatively small movements in forecast headroom can affect the options available to ministers.

The economists told the committee that the OBR had evolved into an institution whose forecasts could effectively determine the boundaries within which fiscal policy was considered possible. Their argument was that the organisation does more than simply forecast economic developments because its assessments can determine whether the government appears to meet its own fiscal rules.

The committee did not accept that such concerns justified fundamentally changing the OBR’s independence. Instead, its report emphasised the importance of maintaining independent economic analysis while considering improvements that could make the organisation’s work more useful to policymakers.

The inquiry comes after a period of scrutiny surrounding the OBR. In December 2025, its then chair Richard Hughes resigned following the leaking of the organisation’s assessment of a previous budget. The episode raised questions about the institution’s internal processes and its relationship with the Treasury.

The latest parliamentary review therefore examined both the OBR’s wider institutional role and the arguments made by those who believe changes are necessary.

The committee’s conclusions indicate that MPs see a distinction between improving the organisation and weakening its independence. While rejecting fundamental reform, they have suggested that the OBR could provide additional long-term analysis and that Parliament should give greater attention to its assessment of future fiscal risks.

The recommendation for a 10-year forecast could become particularly relevant when governments consider major infrastructure projects, public investment programmes or reforms whose financial effects may not become clear within the standard five-year forecasting period.

At the same time, the committee recognised that extending the forecasting horizon brings greater uncertainty. Economic growth, inflation, interest rates, employment, government revenues and public spending can all change significantly over time. Longer-term projections therefore cannot provide the same degree of certainty as shorter-term forecasts.

The OBR already publishes long-term analysis, including assessments extending decades into the future. The committee’s proposal would create an additional medium-term forecast intended to bridge the gap between the existing five-year economic outlook and much longer assessments of fiscal sustainability.

The debate over the OBR is also taking place against a challenging fiscal backdrop. Britain’s government faces significant borrowing and debt pressures, while rising borrowing costs and demands on public services can reduce the room available for ministers to introduce new spending commitments or tax reductions.

The OBR’s own recent analysis has highlighted the difficult fiscal environment. Its March 2026 forecast noted that government debt as a share of national output had increased substantially over the previous two decades and that borrowing costs remained high compared with many other advanced economies.

The government has also commissioned the OBR to prepare another Economic and Fiscal Outlook for October 2026. That forecast is expected to provide an updated assessment of the economy, public finances, government borrowing and debt ahead of important fiscal decisions.

The Treasury Committee’s report comes at a time when the role of independent institutions in economic policymaking is receiving increased attention. The OBR’s supporters argue that independent forecasting can provide greater transparency and allow governments’ fiscal plans to be assessed against consistent economic assumptions.

Critics, however, have questioned the extent to which forecasts from an unelected institution should influence democratically elected governments. The evidence presented to the committee illustrates the continuing disagreement over how much authority economic forecasts should have in determining the boundaries of government policy.

The committee’s position seeks to maintain the OBR’s independent role while considering changes that could improve the usefulness of its analysis. Rather than recommending a fundamental restructuring, MPs have proposed giving policymakers and Parliament more information about the longer-term consequences of economic decisions.

Hillier said the current debate should focus on preserving independent economic analysis rather than undermining the organisation. She also argued that longer-term analysis could help address what she described as a tendency towards short-term policymaking.

The report is now likely to feed into wider discussions about Britain’s fiscal rules, government spending, economic growth and the institutional framework used to assess public finances.

For ministers, the central issue remains how to make spending and taxation decisions while operating within fiscal constraints. For Parliament, the question is how independent economic forecasts should influence those decisions without replacing political accountability.

The Treasury Committee’s findings suggest that MPs see the OBR as an important part of that process while recognising that its forecasting methods and the way its analysis is used can continue to be examined.

The debate is therefore unlikely to end with the publication of the report. As Britain confronts difficult choices over taxation, public spending, borrowing and long-term investment, the role of the OBR will remain closely connected to wider arguments about how economic policy should be assessed and how much weight governments should place on independent forecasts.
