Nigeria’s central bank announced a raft of new policies in recent weeks aimed at strengthening the country’s currency. Several posts on social media shared a statement suggesting that the bank’s new chief, Olayemi Cardoso, had also banned the use of US dollars for domestic transactions. But the claim is misleading; AFP Fact Check found that the statement predates Cardoso by nearly a decade. Moreover, since a 2007 law, the naira has been the only legal tender for transactions in the country.
