In order for credit institutions (comercial and development banks) to fulfill their intermediation function, they need to attract resources, both from the general public, as well as from other banks and non-financial entities. The main collection products offered by credit institutions are: demand instruments, term instruments and interbank instruments. The collection of resources has a cost, which is reflected in the interests that credit institutions pay their savers.Any questions, comments or suggestions, we would appreciate sending an email to the address DISF@banxico.org.mx
