Could a BRICS currency challenge the US dollar?

The most headline-grabbing initiative to challenge the dollar is the suggestion of a common currency for the BRICS bloc. Like the African peace mission, this has been floated by Russia and taken up by South Africa. This, though, would be a long way off. More immediate moves to dilute the dollar’s hegemony could include extending the power of the New Development Bank (NDB) and bilateral deals; promoting an alternative to the SWIFT payment-clearance system; leveraging BRICS countries’ gold holdings and production; and moving into digital currencies.
