Global Daily Tax News, Countries Increasingly Adopting Fiscal Rules, But Adherence Patchy: IMF, (Oct 6, 2025)

The IMF has published a new report highlighting that, although countries are increasingly adopting fiscal rules committing to fiscal prudence, about 40 percent of advanced economies and nearly two-thirds of emerging markets exceed their own fiscal limits.

The report authors said, "countries have increasingly adopted fiscal rules and frameworks that aim to give clarity and predictability to government spending. But these rules have not been as effective in keeping deficits and debt within their intended limits."

The report tracks the evolution of fiscal rules and how countries comply with them, noting these rules have been deployed since the mid-1980s but their use has increased over the last two decades. 120 countries now have fiscal rules.

The authors said, initially, the rules were too rigid and constrained responses to economic downturns. Greater flexibility was eventually introduced and proved effective, allowing governments to provide necessary support for ailing economies, particularly in severe crises such as the pandemic. However, they said, the severe shocks were a significant test for fiscal rules, with many countries' deficits and debt exceeding their own limits, and now more than two-thirds of countries have revised their fiscal rules, often making them more flexible without considerably safeguarding public finances.

The authors said: "For fiscal rules to be effective, they must strike a careful balance: they should safeguard fiscal sustainability while leaving adequate room and flexibility for priority spending. Our analysis shows that effective rules need to have several elements: they are based on a clear and appropriate target or fiscal anchor to guide policy; they have a robust way to correct course when spending pressures or adverse shocks put the rules off track; and there are supportive fiscal institutions to guide and support their implementation."

The report includes the following recommendations for policymakers on the design of credible fiscal rules:

• First, a prudent fiscal anchor – for example, a debt-to-GDP ratio or a medium-term budget balance target – should be tailored within a risk framework to a country's debt capacity and exposure to shocks. To be credible, they must be easy to monitor, clearly communicated to the public, and be closely linked to annual budgets;

• Second, fiscal rules work best when countries have effective institutions to support and implement them. Specifically, medium-term fiscal frameworks should translate fiscal rules into multi-year plans and align short-term budgetary decisions with long-term debt goals, the report says; and

• Third, when thresholds are breached, countries need clear procedures to get back on track. Pre-defined triggers, timelines, and policy responses can help return to fiscal rule limits – such as requiring governments to submit fiscal plans or take corrective actions – and restore discipline, the authors said. Some countries go further, using progressive triggers that activate stricter measures, for example as debt nears critical levels.

The report says well-designed fiscal rules can bring down the cost of servicing public debt. The report includes an analysis of policies in six countries (Armenia, Costa Rica, Cyprus, Czech Republic, Poland, and Slovak Republic), finding that well-designed correction mechanisms helped lower the cost of issuing debt by about 0.3 percentage points within six months and by 0.75 percentage points within a year, compared to similar economies without effective fiscal rules.

The authors concluded: "Governments are facing increasing and legitimate demands to invest in infrastructure, public services, and economic security. Aging societies will require more spending on healthcare and pensions, and many countries are ramping up defense spending. Putting in place fiscal rules is not inconsistent with these goals. But careful calibration and design of these rules is very important. Low-debt countries may ease their limits to support growth-enhancing spending as long as their debt remains within debt stabilizing limits. By contrast, high-debt countries need to match any new spending with revenue increases and/or reallocate existing expenditures to avoid adding to fiscal and debt risks."

"As these pressures intensify, countries must strengthen – not weaken – their commitment to fiscal discipline and ensure that public finances remain a source of stability, not vulnerability."
