On the dynamics of lending and deposit interest rates in emerging markets: A non-linear approach

Abstract

This paper studies the dynamics of lending and deposit rates in two emerging markets in Latin America: Colombia and Mexico. The dynamics of lending (deposit) interest rates are driven by the exogenous interbank interest rate and deviations from the long-run lending-interbank (deposit-interbank) interest rate relationship. Allowing for different interest rate behavior during periods characterized by large and small values of the spread, the non-linear specification proves superior to the linear one.
