The plan is to have a currency that's backed by a basket of commodities that BRICS countries produce. Given that BRICS countries are where most of commodities and manufacturing is located, I definitely see a rapid rise for such a currency. Especially coupled with projects like BRI that China is aggressively pushing. China will be building infrastructure in developing countries on a massive scale, and all the trade that will result from that will most likely be done in the BRICS currency.
