The Treasury, formerly the Royal Treasury, is the Oceanan government department responsible for monetary policy, the Oceana Central Bank, the Oceana Industrial Development Bank, and some aspects of banking regulation. It is the oldest government department, having existed in some form since the Neustrian Conquest, and was formerly responsible for all aspects of fiscal and economic policy until the Revolution and the creation of the Department of Finance. It is headed by a Treasurer, currently Lewis Read.
