The limits of “soft power”: independent fiscal institutions and fiscal discipline in Sub-Saharan Africa

Fiscal consolidation remains a pressing governance challenge in Sub-Saharan Africa (SSA), where persistent deficit bias and rising public debt threaten macroeconomic stability. Several countries have created independent fiscal oversight bodies, but their effectiveness in the region remains uncertain. Using a panel of 46 SSA countries from 2000–2024, we exploit staggered IFI adoption in Uganda, Kenya, Nigeria, and South Africa. Because only four countries are treated, the estimates require cautious interpretation. Across the preferred Callaway–Sant’Anna specification and robustness checks using the cyclically adjusted primary balance, fiscal-rule and sovereign-wealth-fund controls, and an IFI-strength measure, we find no statistically detectable improvement in primary balances after adoption. Weak institutional complementarity is one plausible explanation: reputational and accountability channels may be muted where media independence, legislative responsiveness, and civil-society engagement are limited. Limited statistical power and measurement constraints provide additional explanations. Fiscal outcomes are more consistently associated with commodity cycles, electoral pressures, and IMF-programme participation. The results suggest that IFIs are more likely to contribute to fiscal discipline when embedded in a broader accountability environment.
