When it comes to the east the Chinese have an operating banking system that managed things like loan, borrowing, saving, and interest rates. However the nature of Chinese banks were different from the western style of banking you'd see in Europe later on. Namely they focused on lending out to people they had closer relationships with like family or friends who may own a business. Or just the local village or town maybe.

The general inherent weaknesses of traditional Chinese Law at the time discouraged larger-reaching and more complex banking because it was just unstable or not very viable. So you'd see a lot of depositing for the long-term, short term shit, and [url=http://en.wikipedia.org/wiki/Float_%28money_supply%29]floating[/url].

And the two major systems the Chinese had didn't try to compete like Goldman-Sachs and... Whoever else. In the Chinese environment they just sort of bounced off of each other. But then again this probably lends to Chinese law not being a great environment to what we see as western banking and they did it to maintain each other's Shanxi and Yangxi based banks so they exchange Song paper notes with Mongolian sheep pelts or whatever the Vietnamese traded in; lizards I guess.

And in India there's parts of the Vedas that detail and discuss unethical money lending.

But that's about as far as I can get while trying to pay half-attention in class.

But most likely given the "primitive" way the land is organized and connected the sort of European model of "Dude A writes IOU to dude B with interest who later turns it into Dude C who pays him what the IOU is worth" would be more than workable. We could assume the Visha - in their supposed enlightenment - had a better understanding born out of the centralization of their realm. But the details or proper understanding of the methods left the world with their automatons when their world caved in.
