The 41 item exclusion list is no news. In June of 2015, in response to the collapse of foreign exchange inflows, thanks to the crude oil price crash, the central bank decided to change tactics in its quest to maintain a “stable” naira. It abandoned the policy of drawing down on the foreign reserves and opted to just ban certain market participants from the official foreign exchange markets. This, it argued, would reduce pressure on the exchange rate. Demand management they called it. In doing this it drafted a now infamous list of 41 items that were banned from buying foreign exchange from the official markets. The list included things like palm oil, rice, toothpicks and eurobonds.

The logic was simple. If foreign exchange is scarce then we have to prioritise what we spend it on. We can’t keep spending scarce foreign exchange importing things that we can produce locally. In the abridged words of the central bank governor; “why do we continue to import when our vast quantities of comparable quality products are being wasted or simply ignored”. I mean, why spend scarce foreign exchange importing palm oil when we have it in the South South. Why import rice when we can grow it locally. The tacit assumption was that if certain items were banned from the foreign exchange market then people would not import them, and we would produce them locally. And it all kind of makes sense, especially if you don’t know much about economics.

Now I’m not writing this to convince you that the policy works or not. I am here to tell you that there is one item missing from that list. There is a 42nd item that, for unknown reasons, was excluded. A product that Nigeria should be known for. A product that we have all the necessary ingredients to produce locally. A product that we really should not be importing but should even be producing a surplus and exporting. That product is premium motor spirit, popularly known as fuel.

Finally, we have the market for fuel. We consumed about 51.5 million litres of fuel per day on average in 2016. We consume so much fuel that it is has been the single largest imported item for decades. In terms of value, we spend 250 percent more foreign exchange importing fuel, not including diesel or kerosene, than we do for all food, including rice, palm oil, wheat and everything else. In fact, I would argue that if we somehow stopped importing fuel today, our foreign exchange crisis would be over, albeit temporarily.

So just to recap, we have the raw materials, the skills, and the market, and if we stopped importing fuel our foreign exchange crisis might be over. If the central bank really believed that banning products from the official markets really led to local production of that product, then why isn’t fuel on the list. Surely fuel should be the 42nd item.

Fortunately, discussing the crude oil industry is a national pastime. We talk about it every other day and we know, beyond the shadow of doubt, the challenges in moving from drilling oil to producing fuel. We know that in reality producing fuel is a lot more complicated than banning fuel imports or banning fuel importers from foreign exchange markets. We know that if we banned fuel importers from buying dollars then all that would happen is the pump price of fuel would go up. We will probably still import it and not produce it locally.

If the central bank really believes that its 41 items exclusion list does anything other than create distortions in the foreign exchange market, then it should ban fuel importers so we know it’s real. Else it should be abandoned for causing more problems than it solves.
