Abstract: This note introduces the Health Financing Volatility (HFV) Index, a methodological framework for quantifying short-term instability in health-financing flows. The HFV Index adapts the volatility concept of Bulíř & Hamann (2008) to the health sector by combining Hodrick-Prescott (HP) filter residuals with a rolling three-year standard deviation.The framework can be applied to di erent components of health financingexternal, domestic, or totalyielding respectively the External Health Financing Volatility (EHFV), Domestic Health Financing Volatility (DHFV), and Total Health Financing Volatility (THFV) indices.An illustrative application to Senegal and Mali (2000-2022) demonstrates how volatility patterns di er between two West-African fiscal contexts. The HFV Index provides a simple, scale-independent tool for assessing instability in health financing, strengthening fiscal coordination, and supporting progress toward Universal Health Coverage (UHC).
