I'm relatively sure that the Romans knew a kind of banks and credits. A stock exchange is another thing, of course.
Hmm. This is so intriguing that this suggests a POD.
"Roman banking may have been largely monetized, but it also displays a distinct lack of sophistication in the use of money in comparison with Italy after the commercial revolution of the 13th century. In Medieval Italy it was possible to make payments by transfer between different banks, and both cheques and negotiable paper came into existence. Perhaps even more important was the bill of exchange, which which proved vital in the development of commercial exchange in Europe in the 13th century. "
So far, so good. But what about Rome?
"In the roman world, outside of Egypt, there are no traces of affiliation between banks in different places.... this means that, indefault of any clearing system, banks could not be used to transfer funds from one place to another. Perhaps even more important... there were no bills of exchange and no negotiable paper. Furthermore, cheques.... are unknown outside of Egypt."
Furthermore, "Even in Egypt cheques relied upon trust of the payee (there was no relevent legislation[1]) and there is no evidence that cheques could be endorsed so as to become negotiable. The vulnerability of banks, in which interest bearing deposits could be withdrawn on demand and partnerships were dissolved by the death or wish of one party, cannot have been conducive to the devleopment of complex procedures, or to the full use of such services as were offered."
"In the Roman world the possibility of moving funds without the physical transer of coin was confined to the elite, who could rely on friends with widespread interests, or to those who, like governors under the Republic, could make private use of the system for the transfer of tax revenues through publicani. Under the Principate there appears to be no evidence of private individuals taking advantage of the government's mechanism for the transfer of revenues or through the publicani."
And, tantalizingly, for the purposes of a WI, "Part of the explanation for the explanation for the lack of sophistication of Roman banking may be that banks were not, for the most part, used by the elite".
Hmm. I'm thinking the best POD would be something with the Publicani, but I'm not sure.
Thoughts, anyone?
