The International Monetary Fund (IMF) says the long-term rate of the depreciation of the naira equates to a loss of 10.6 percent of its value annually since 1973.
According to the IMF, this rate is 1.5 times higher than the long-term rate of the currencies of other emerging markets and developing economies at 7.2 percent, and Sub-Saharan Africa at seven percent over the same period.
The Washington-based lender disclosed this in its ‘Nigeria: Selected Issues Paper’ report. According to the report, this is one of the reasons why Nigeria’s inflation rate is higher than that of its peers.
The report read in part, “Nigeria’s long term average rate of CPI inflation (1971-2020) was 16 percent, which is higher than both SSA (13 percent) and EMDE (13.6 percent) averages.
“Compared to SSA (7.2 percent) and EMDE (6.2 percent) median, the difference is more pronounced. Two possible explanations come to one’s mind upon data investigation. First, Nigeria’s broad money (M3) growth has been persistently high — with its 50-year average registering 21.2 percent. This is 1.5 and 1.3 times more than EMDE (18.5 percent) and SSA (16.7 percent) averages respectively.
“Likewise, its exchange rate underwent more persistent depreciation. Nigeria’s long-term rate of currency depreciation (on average 10.6 percent annually since 1973) was 1.5 times higher than both EMDE (7.2 percent) and SSA (seven percent). Given the limited availability of long-term data, it is difficult to estimate the exact reasons.
“However, the historical behavior of NEER shows that Nigeria’s NEER depreciation episodes tended to be more abrupt and disorderly compared with EMDE and SSA peers, where exchange rate adjustments have been far more continuous and smoother.
“It would thus not be implausible that the more reactive and disruptive exchange rate adjustment tends to be, the larger the risk of the inflation-depreciation spiral would become—because expectations are unhinged, and confidence undermined more.”
According to the IMF, Nigeria utilized an exchange rate anchoring strategy, shifting from a flexible regime to a fixed one in 2004.
It added that while this might have helped to stabilize the nation’s inflation expectations in the interim, it unraveled in 2015 as the global oil price crash plunged the naira into a spell of large, repeated depreciation.
It added that in recent times, exchange rate shocks had played an important role in recent inflation dynamics.
According to the IMF, exchange rate shocks have accounted for about 38 percent of the overall price shock, with about 62 percent of naira’s depreciation being reflected in inflation.
It said, “Exchange rate shock is estimated to have accounted for 38 percent of the overall price shock. However, our analysis suggests that the exchange rate shock has been plateauing.
“Our estimation also shows that despite the CBN’s various attempts to defend the I&E rate, which has helped contain exchange rate shock to inflation to a degree, 62 percent of naira’s depreciation as reflected in the BDC rate (which is more deprecated than I&E rate) has already been passed through to inflation.”
