The Committee of Sadc Stock Exchanges (CoSSE), which starts a two-day meeting in Cape Town today, is expected to finalise the agreed hub-and-spoke exchange interconnectivity model.
Brokers have sought a vehicle to provide information on companies operating in the region, monitor their performance and explore opportunities for clients.
Geoff Rothschild, CoSSE chairman and the JSE's director of government and international affairs, said implementation would "expose our neighbours' business organisations to local and international investors".
"This hub will allow exchanges to connect to each other's platforms and ultimately allow investors to trade on all Sadc exchanges through their local brokerage."
Rothschild said serious investment was needed to upgrade technology for all the region's exchanges. Many had expressed willingness to do so but funding remained a problem.
The meeting's main themes are regional integration, alignment of listing requirements and technical interconnectivity.
CoSSE was established in 1997. Botswana, Malawi, Mauritius, SA, Mozambique, Namibia, Swaziland, Tanzania, Zimbabwe and Zambia are members.
