By the end of the 16th century and during the 17th, the traditional banking functions of accepting deposits, moneylending, money changing, and transferring funds were combined with the issuance of bank debt that served as a substitute for gold and silver coins.
New banking practices promoted commercial and industrial growth by providing a safe and convenient means of payment and a money supply more responsive to commercial needs, as well as by "discounting" business debt. By the end of the 17th century, banking was also becoming important for the funding requirements of the combative European states. This would lead on to government regulations and the first central banks. The success of the new banking techniques and practices in Amsterdam and London helped spread the concepts and ideas elsewhere in Europe.
