Different types of capital inflows have varied effects when predicting banking crises in emerging and developing economies, and these relationships have meaningfully changed over time. In a sample of 29 developing and emerging economies over the period 1976–1991 increases in short‐term debt inflows raised the probability of a banking crisis while increases in inflows for long‐term borrowing by the private sector had the opposite effect. Conversely, over the period 1992–2007 increases in inflows for long‐term borrowing by the private sector and for equity investment both increased the probability of a banking crisis. The findings suggest distinct optimal capital account liberalization policies between the two periods.
