…according to the data, we do not have an import problem… However, we do have an export problem, highlighted by the fact that crude oil accounts for 90% of our recorded exports and crude oil prices are volatile. Recognising this key difference between an import problem and an export problem is very important because it determines that kinds of policies that should be implemented. Import substitution policies and policies that look to limit imports probably won’t work because they do nothing to tackle the real problem, which is an export one.
The naira issue has been the topic of debate for a while now. Should we devalue or not? Can we cope with the effect of a devaluation? What happens if we don’t? And so on. Over the next few days, I and other colleagues-experts in their fields-will give views on a variety of issues regarding the naira devaluation debate.
To kick things off, it is useful to discard some bad ideas which have been tossed around for a while.
Bigger Number = Stronger Currency?
The first myth to debunk is the false idea that if you exchange a bigger number for a smaller number then the currency with a bigger number is weaker than the currency with a smaller number. You typically hear people say:“Wow, one dollar is exchanging for 16 rand. The rand is weak. The dollar is strong.” That kind of thinking is faulty mostly because it doesn’t take into account the purchasing power behind the currency.
For example, if an individual living in the US earns 300 dollars a month, then that is technically identical to an individual in South Africa earning 4800 rands a month, given that 1 US dollar exchanges for 16 rands. So long as that exchange rate holds then the rand is not weak or strong, it’s just the rand.
In reality, the strength or weakness of a currency has little do with what the actual exchange rate is. So although one Ghanaian cedi exchanges for 30 Japanese yen, you cannot say the cedi is stronger than the yen. Similarly, although one Turkish lira exchanges for six Mexican pesos, you cannot say the lira is strong and the peso is weak. That would be wrong.

What then determines a currency that is “weak” or “strong”?
A weak or strong currency is one that is changing, or that everybody expects to change soon. For example, if the naira changes from 150 to the US dollar to 165 to the US dollar, then during the period the change is taking place the naira is relatively weak and the dollar is relatively strong. The same applies if the currency is expected to change soon. If everyone expects the naira to change from 197 per US dollar to 300 per US dollar, then the naira is weak relative to the dollar. The weakness persists as long as the expectations about the change persist. If the change eventually happens, the naira moves to 300 to a dollar, and everyone believes that is the end of it, then the naira is no longer weak. It is just the naira.
Weak Currency = Bad Economy?
The second myth to dispel is the idea that a country whose currency weakens consistently over time cannot grow. This could not be further from the truth.
The poster child of why weakening currencies do not imply slow growth is South Korea. South Korea grew its GDP per capita from about 1100 US dollars in 1960 to about 24,500 in 2014. What happened to its currency over the period? In 1960 one US dollar exchanged for about 63 won. Today one US dollar exchanges for almost 1200 won. In short, over the period where South Korea has “developed”, its currency has also weakened consistently.
…a currency that loses value over time is not the doom it is made out to be.
Similar patterns can be seen for some of the other fastest growing economies over the period, such as Chile, Vietnam, and Indonesia. The majority have grown relatively quickly even with weakening currencies. In fact, many countries try to weaken their currencies to boost growth. One of goals of Abenomics, a fancy name for policies implemented by the Japanese Prime Minister, was a devaluation of the yen to boost growth. China was accused for years of artificially weakening its currency.
There are many other examples from around the world. The Vietnamese dong trades at 22300 per US dollar today from about one dong per US dollar in 1983 and Vietnam still managed to grow at an average of 6.5% per year over the period. The Indonesian rupah trades at 11,800 per US dollar today from about 600 rupahs per US dollar in 1980 and Indonesia also still managed to grow at an average of 7% per year over the period. Bottom line, a currency that loses value over time is not the doom it is made out to be.
Devaluation = Uncontrollable Inflation?
The third myth is the idea that devaluations lead to runaway inflation, an idea that is not technically true. To be clear, devaluations do lead to inflation but not nearly as much as people think.
For example, the South African rand has devalued by about 40% in the last year yet inflation has ticked up by less than one percentage point to 5.2% from 4.4% a year ago. The Russian rubble has devalued by 126% since the middle of 2014 yet inflation has gone from 8% in mid-July of 2014 to about 13% today, although it peaked at around 16%. A significant increase, but nowhere near catastrophic.
…the reality is, devaluations do cause inflation but not that much… Ironically, according to some studies, the black market premium, i.e. the difference between the official exchange rate and the black market exchange rate is a bigger driver of inflation than devaluations.
Finally, we can look at Nigeria where the naira lost about 20% of its value between October 2014 and March 2015. Despite the devaluation, inflation, which was about 8% then, is still below 10%. If you add the fact that the dollar prices of some of our largest imports, fuel and wheat, have fallen to almost record lows then the inflation worry is minute.
So the reality is, devaluations do cause inflation but not that much. Despite a devaluation, the Central Bank still has lots of tools at its disposal to keep inflation in check. Ironically, according to some studies, the black market premium, i.e. the difference between the official exchange rate and the black market exchange rate is a bigger driver of inflation than devaluations.
Does Nigeria Have An Import Problem?
The final myth to bust is the idea that Nigeria has an import problem. You typically hear statements like “How can we be importing everything from toothpicks to fish. It is unsustainable.” Often left out of such statements is the fact that we have a N90tn economy. And you cannot have a N90tn economy that does not import. Is it odd that a N90tn economy would import N100bn worth of building materials or N26bn worth of shoes? No it’s not.
According to comparable data compiled by the World Bank, Nigeria imported only about 12.5% of GDP in 2014. Of the 160 countries for which the World Bank has data available, Nigeria had the lowest imports to GDP ratio. Côte d’Ivoire imported about 38.9% of GDP in 2014, Ghana imported about 48.9%, Mauritius imported about 63%, Belgium about 83.1% and Ireland about 95.4% of GDP.
Of the 160 countries for which the World Bank has data available, Nigeria had the lowest imports to GDP ratio.
So according to the data, we do not have an import problem. Even if you assume that 50% of our imports go unrecorded, that still leaves us at a healthy 25% of GDP, which is still not a problem.
However, we do have an export problem, highlighted by the fact that crude oil accounts for 90% of our recorded exports and crude oil prices are volatile. Recognising this key difference between an import problem and an export problem is very important because it determines that kinds of policies that should be implemented. Import substitution policies and policies that look to limit imports probably won’t work because they do nothing to tackle the real problem, which is an export one.
