The BRICS reserve currency is a basket-based reserve currency12that is being developed by Brazil, Russia, India, China, and South Africa1. It is meant to rival the US dollar and the IMF's Special Drawing Rights (SDRs) currency3. The currency is presumed to comprise real, roubles, rupees, renminbi, and rand1. The Contingent Reserves Arrangement is a pool of foreign currency that any of the BRICS countries can dip into if they need to4.
