Only one of Cricket South Africa's three domestic sponsors remain in place ahead of the 2018-19 season, in which there could be no corporate backing for either the franchise first-class competition or the 20-over tournament. Only the 50-over format continues to be sponsored, by the financial services company Momentum.
Sunfoil, the sponsors of Test cricket and both the franchise four-day and provincial three-day competitions, opted not to renew its deal with CSA at the end of the 2017-18 summer, ending a relationship which lasted seven years. ESPNcricinfo understands that the company would prefer to use its marketing budget differently. A CSA spokesperson said the organisation is at "at a more advanced stage in negotiations with a replacement and are confident we will be able to conclude the arrangement soon".
In the shortest, and most troubled format, for CSA, courier company RAM have decided not to back the T20 Challenge. RAM re-signed for the 2017-18 season, when the tournament replaced the postponed Global League T20 (GLT20), after also pulling out of a deal with CSA in 2016. For the 2018-19 summer, the competition has no sponsor and, given its timing and the uncertainty over whether another 20-over competition will also take place in South Africa, it is difficult to see how it could attract a backer.
