IFS Demands Overhaul of Chancellor's Fiscal Rules Ahead of Spring Statement
The Institute for Fiscal Studies has launched a scathing critique of Chancellor Rachel Reeves' fiscal rules, labelling them as "dysfunctional" and undermining sustainable public finances. With the spring statement approaching on 3 March, the influential economic think tank is urging a fundamental shift towards a more nuanced system of fiscal targets.
Timing and Context of the Criticism
The IFS has strategically timed its intervention to coincide with the upcoming spring statement, where the Office for Budget Responsibility will no longer assess whether Reeves is on track to meet her fiscal rules. This change, which moves such assessments to the annual Budget only, is welcomed by the IFS as it reduces short-term market pressures. However, the watchdog argues that the current framework remains deeply flawed despite this procedural adjustment.
Reeves' Current Fiscal Framework
Chancellor Reeves operates under two primary fiscal rules:
- Current spending must be matched by tax revenues by 2029-30
- National debt must begin falling relative to national income by the same period
These rules were designed to create borrowing headroom for infrastructure investment, particularly after the 2024 redefinition of national debt to "public sector net financial liabilities" which offset debt with assets like the student loan book. Additionally, a flexible welfare cap allows spending increases during economic downturns.
Fundamental Flaws in the Current System
The IFS identifies several critical problems with Reeves' approach:
- Aggressive gaming of rolling targets that undermines credibility
- Frequent rule changes that create instability
- Overly simplistic pass/fail measurements
- Manifesto commitments restricting tax options
- Insufficient buffer for external shocks like Trump tariffs
Like her Conservative predecessors Jeremy Hunt and Rishi Sunak, Reeves' rules rely on optimistic projections about future deficit reductions, often based on unspecified spending cuts. Her self-imposed restrictions on raising income tax, VAT, and national insurance contributions have created what the IFS describes as a "fiscal straitjacket."
Historical Context of Fiscal Rules
Fiscal rules have become standard practice since Geoffrey Howe's Medium Term Fiscal Strategy in the early 1980s, designed by then-junior Treasury minister Nigel Lawson. Gordon Brown's "golden rule" in 1997 established the principle of borrowing only for investment, not current spending. Subsequent chancellors have largely followed variations of this approach, despite their limitations becoming apparent when markets lose confidence, as demonstrated during the Kwasi Kwarteng and Liz Truss premiership.
IFS Recommendations for Reform
The think tank proposes a comprehensive overhaul:
- Multiple fiscal targets replacing the current binary system
- A traffic-light measurement approach for greater nuance
- Medium-term strategic planning reminiscent of Thatcher-era approaches
- New rules to be presented to voters at the next election
Notably, the IFS does not recommend major institutional changes, supporting the continued operational independence of both the OBR and Bank of England. This position aligns even with Reform UK's Treasury spokesperson Robert Jenrick, who advocates maintaining the status quo regarding these institutions.
The Ultimate Fiscal Reality
Ultimately, the IFS acknowledges that any fiscal framework ultimately reflects what financial markets will tolerate when lending to Britain at sustainable interest rates. Markets serve as the unseen architects of all fiscal rules, possessing the power to enforce discipline through their reactions to government policies. As the UK economy shows modest growth of 0.1% in the final quarter of 2025, the debate over fiscal rules takes on renewed significance for long-term economic stability.
