>BRICS has implemented initiatives that could reform the global financial system, such as the New Development Bank, the BRICS Contingent Reserve Arrangement, BRICS PAY and the BRICS Joint Statistical Publication. BRICS has also advanced de-dollarization to reduce the use of the U.S. dollar as reserve currency. In its first 15 years, BRICS has established almost 60 intragroup institutions and an extensive network including think tanks and dialogues.
