South Africa over throws Nigeria as Africa’s largest economy

South Africa has regained the title of Africa’s largest economy, two years after Nigeria rebased its economy to claim the spot, according to IMF data.

A recalculation using current exchange rates put South Africa on top because the rand has strengthened against the dollar.

Nigeria’s currency has fallen sharply since a peg to the dollar was dropped.

But BBC Africa Business Report editor Matthew Davies says both economies could be on the brink of recession.
