TIIE (Equilibrium Interbank Interest Rate) is a rate that represents interbank credit transactions. TIIE is calculated on a daily basis (for periods of 28, 91 and 182 days) by Banco de México based on quotations presented by banks through a mechanism designed to reflect money market conditions in local currency.

TIIE is used as a reference for diverse financial instruments and products such as credit cards.
