Data compiled by the International Air Transport Association shows that airlines operating in Nigeria were unable to repatriate $783 million in ticket sales revenue as of August 2023, the largest blocked-funds backlog held by any single country in the world. The figure has climbed steadily through the year, from roughly $662 million in January to $743.7 million by March, according to correspondence IATA sent to the Ministry of Aviation.
The blockage stems from a chronic shortage of US dollars at Nigeria's official foreign exchange window, which has left the Central Bank of Nigeria unable to clear the naira-denominated ticket revenue that international carriers are contractually required to convert and remit abroad. IATA's regional leadership has repeatedly warned that the scale of the backlog threatens the viability of foreign airline routes into the country and, by extension, Nigeria's connectivity to the rest of the world.
Airlines Scale Back Rather Than Absorb Losses
The dispute has already reshaped the market. Emirates suspended all flights to Lagos and Abuja in October 2022 over the same issue and has yet to return, while other carriers have quietly trimmed frequencies or paused ticket sales in naira to limit their exposure. Foreign airline executives have told Nigerian officials at successive stakeholder forums that continuing to fly into the country while revenue piles up unconverted is not commercially sustainable indefinitely.
At a forum with the Ministry of Aviation, representatives of the affected carriers said roughly 90 percent of the blocked total remained completely inaccessible to them, despite periodic partial releases by the central bank in prior years. Industry groups have called for a clear, published timetable for clearing the arrears rather than the ad hoc disbursements that have characterised the government's response so far.
A Problem Inherited by the Incoming Administration
The scale of the backlog places significant pressure on the newly inaugurated government of President Bola Tinubu, whose economic team has pledged to unify Nigeria's multiple exchange rate windows in a bid to close the very arbitrage gap that has made it difficult to source dollars for airline remittances. Whether that reform translates into a faster resolution for foreign carriers is likely to shape how many of them choose to maintain, cut, or restore service to Nigeria over the coming months.
