The membership of the association is open to any Securities Exchange or nascent Stock Exchange located in the African region after filling the membership application and getting the Executive Committee approval.

In August 2005, the Bourse des Valuers Mobilieres de L' Afrique Centrale (BVMAC), a private organization owned by some of the largest financial institutions and industries of the Central African region, applied for ASEA membership, which was approved by ASEA Committee during its 9^th meeting, on the condition that the BVMAC keeps the association informed of developments and notifies the ASEA when the BVMAC is finally incorporated as a regional securities exchange and is operational. It’s worth mentioning that through the CEMAC (Central Africa Economic and Monetary Union) Treaty, the six governments of the CEMAC (Cameroon, Congo, Gabon, Equatorial Guinea, Chad and Central African Republic), have given BVMAC the exclusive mandate to animate and develop a regional stock exchange.
