Central Africa's regional banking regulator sent out a reminder on Friday about its ban on cryptocurrencies.

The Central African Republic's presidency announced on April 27 that bitcoin had been made legal tender, making it only the second country to do so after El Salvador.

Reached by phone on Friday, government spokesman Serge Ghislain Djorie told Reuters that Central African Republic had received no official notice from the COBAC about a crypto ban, although he had seen the news in the press and on social media.

The banking commission held a special meeting on May 6 to examine the impact of cryptocurrencies in the zone, it said in the statement on Friday.

"In order to guarantee financial stability and preserve client deposits, COBAC recalled certain prohibitions related to the use of crypto-assets in CEMAC," it said.

These include the holding of cryptocurrencies of any kind, the exchange, conversion or settlement of transactions relating to cryptocurrencies and a bar on them being used as a means of evaluating assets or liabilities, it said.

"COBAC has decided to take a number of measures aimed at setting up a system for identifying and reporting operations related to cryptocurrencies," it added.
