Why have financial intermediaries developed?
Financial intermediaries, an important part of the financial system, have evolved with the purpose of lowering transaction costs and allowing small savers and borrowers to benefit from the financial markets. One solution to the problem of high transaction costs provided by financial intermediaries is to pool the funds of many investors together so that they can take advantage of economies of scale, which is the reduction in transaction costs per dollar of investment as the size of transactions increases. The presence of economies of scale in financial markets helps to explain why financial intermediaries have developed and have become such an important part of our financial system.
