Interbank Interest Rate

The Interbank Interest Rate is the rate at which banks lend and borrow short-term funds from each other, usually on an overnight basis. It is a key indicator of liquidity conditions and the stance of monetary policy, closely tracking central-bank policy rates across Latin America and the Caribbean. The series is published in the Latin Macro Watch dataset maintained by the Inter-American Development Bank (IDB).

Coverage

Data are available for 20 countries across Latin America and the Caribbean at annual, monthly, and quarterly frequency, spanning 1995 to 2026. Values are reported as a rate and in real terms, each available in average-of-period and end-of-period variants.

Sources

Figures are compiled from official national authorities, including Banco Central do Brasil, Banco de Mexico (Banxico), Banco Central de Chile, Banco de la República de Colombia, and Banco Central de la República Argentina, among other central banks and supervisory bodies across the region.
