South Africa will this week take some initial steps to unseat the US dollar as the preferred worldwide currency for trade and investment in emerging economies.

Thus, the nation is expected to become party to endorsing the Chinese currency, the renminbi, as the currency of trade in emerging markets.

This means getting a renminbi-denominated bank account, in addition to a dollar account, could be an advantage for African businesses that seek to do business in the emerging markets.

The move is set to challenge the supremacy of the US dollar. This, experts say, is the latest salvo in the greatest worldwide currency war since the 1930s.
