The government, with its substantial oil revenues, is the dominant supplier of foreign exchange and the commercial banks act as buyers of foreign exchange mainly on behalf of their customers. CBO has an important role to play in the foreign exchange market in the operation of the pegged exchange rate regime and its sustainability.

The speculative demand for forex is contained to some extent by restrictions imposed on banks’ open position limits .
