Definition: Financial intermediation services indirectly measured (FISIM)
As well as charging customers directly for banking services financial intermediaries also provide services for which no explicit charges are made. The latter are known in national accounts as the financial intermediation services indirectly measured (FISIM). In the case of FISIM, service income is generated by paying or charging different rates of interest to borrowers and lenders. The intermediaries pay lower rates of interest than would otherwise be the case to those who lend them money, and charge higher rates of interest to those who borrow from them.
