In a press statement issued Thursday morning, the central bank said although the Foreign Exchange Act, 2006 (Act 723) prohibited the pricing and the payment in currencies either than the local currency, it had noticed that some institutions, companies and individuals were dealing in the "business of foreign exchange trade without authorisation from the bank."

"The general public is hereby reminded that the Foreign Exchange Act, 2006 (Act 723) prohibits the pricing, advertising, receipt or payment for goods and services in foreign currency in Ghana."

"Such violations are punishable by law by summary convictions, a fine of up to seven penalty units or a prison term of not more than 18 months, or both," the statement, which was signed for the Secretary of the bank, said.

It emphasised that "the sole legal tender in Ghana is the Ghana cedi or Ghana pesewas."

The warning from the central bank comes at a time "dollarisation," a term for the practice of pricing, advertising and receiving payments in US dollars, is ripe, with automobile companies, hotels and multinationals, being the biggest culprits.

These culprits mostly cite the instability of the cedi as bases to resort to dollarisation, which is seen as a hedge against depreciation.

It is not clear how BoG's current directive will be received, given that similar ones in the past have achieved minimal results.
