Nigeria is Africa’s largest exporter of crude oil. The oil price falls have exposed vulnerabilities in the country (its government, for example, earns around 80% of its revenue from oil).

Nigeria’s currency, the naira, is under pressure and the central bank has imposed trading restrictions:

  • has banned dealers from depositing their currency-trading funds overnight, preventing them from after-hours trading and placing bets for or against a single currency at the close of a trading session
  • The move is temporary, according to Olakanmi Gbadamosi, director of the central bank’s trade and exchange department.
