The country’s external reserves rose to more than two-year high of $31.22bn on August 8, data from the Central Bank of Nigeria showed on Wednesday.

The foreign exchange reserves, which have been battered by lower oil prices, climbed back to a level they last reached in July 2015, shortly after President Muhammadu Buhari took office, the data showed, Reuters reported.

The external reserves had gone down as low as $24bn last year. For some months, the country’s dollar reserves were hovering around $30bn.

Meanwhile, The CBN is planning to sell N62.43bn ($171m) of treasury bills at an auction next Wednesday.

The bank is planning to offer N32.43bn in three-month paper and N30bn of a six-month bill. Results of the auction will be announced on the same day.

The central bank issues treasury bills twice a month to help the government to finance its budget deficit, curb money supply growth and provide an avenue for lenders to manage liquidity.
