Stanbic IBTC Bank also said it has pegged its daily limit at $300.
In 2015 after a drop in crude oil prices resulted in reduced forex earnings for the country, banks had adopted the strategy of dollar rationing to preserve forex.
In March, Zenith Bank and Guaranty Trust Bank had sent notices to customers notifying them of lowered daily international spending limits of $300.
While Zenith Bank lowered monthly limits to $1,000, Guaranty Trust Bank lowered monthly limits to $500.
The Central Bank of Nigeria (CBN) had adjusted the value of the naira on the foreign exchange market in response to market pressure.
CBN, amid the economic situation caused by a drop in crude oil price to below $30 per barrel, seeks to ensure that the financial market of the country does not suffer a great loss.
It also seeks to conserve dollar reserves.
