Nigeria ordered four banks including Citigroup Inc and Standard Chartered Plc to return $8.1 billion it says was illegally expatriated by mobile-phone company MTN Group Ltd over eight years through 2015.
The wireless operator “strongly refuted” the claim.
The four banks, which include Nigeria’s Stanbic IBTC Holdings Plc and Diamond Bank Plc, will be fined about 5.9 billion naira ($16 million), Nigeria’s central bank said in an emailed statement Wednesday.
MTN was also ordered to participate in the refund.
The order comes almost two years after Johannesburg-based MTN was first accused of the practice. Nigeria’s senate said in 2016 that it was investigating the same four banks for transferring almost $14 billion for MTN in breach of the country’s foreign-exchange rules, but last year the lawmakers ruled the wireless company hadn’t violated the law.
MTN said in 2016 that it obtained central bank approvals before any dividends were issued.
“The re-emergence of these issues is regrettable as it damages investor confidence and, by extension, inhibits the growth and development of the Nigerian economy,” MTN said in a statement on Thursday. “
We will engage with the relevant authorities and vigorously defend our position on this matter and provide further information when available.”
The decision will come as a blow to MTN, because the company has already settled a separate, $1 billion fine in Nigeria for missing a deadline to disconnect unregistered customers. Negotiations over that penalty went on for almost a year and weighed heavily on the share price, which has never recovered.
As part of the settlement, MTN agreed to list its local unit in Lagos and is planning to do so this year. Citigroup is working on that plan.
Standard Chartered received the largest penalty Wednesday for transferring the biggest amount of $3.4 billion, with Citigroup responsible for $1.7 billion. Stanbic IBTC is engaging with the central bank over the issue, it said in a statement on Thursday. The other lenders didn’t immediately comment.
Nigeria is MTN’s biggest market with more than 54 million customers, out of 221 million worldwide. The share price has slumped 21% this year to R107.34, valuing the company at R202 billion ($14 billion), and touched eight-year lows earlier this month.
