The Central Bank of Tunisia conducts a flexible exchange policy.

The Tunisian dinar (TND) exchange rate is determined on the interbank market. In this framework, local banks exchange the currencies among themselves or with their customers at freely-negotiated rates. The role of the Central Bank of Tunisia consists in its intervention to fine-tune liquidity on the market in case of imbalance between supply and demand for currencies on this market.
The Central Bank of Tunisia publishes, for disclosure, the currencies'daily average exchanges rates applied on the interbank market over the previous day.
