4.3 Roman Currency and Finance

Roman currency and finance were crucial to the empire's economic growth and stability. From early barter systems to complex coinage, Rome's monetary evolution reflected its expanding power and sophistication. The denarius became the standard coin, facilitating trade across the vast empire.

Banking and credit systems developed alongside currency, enabling large-scale commerce and investment. Public and private banks managed funds, while financial instruments like checks and promissory notes supported long-distance transactions. These innovations fueled Rome's economic engine and shaped its social dynamics.
