The World Bank Group on Monday raised fresh concerns over the dwindling fortunes of Nigeria’s economy, saying that the country’s economy has been on a downward slide since 1995.

Meanwhile, the global apex bank has also cut the country’s growth projections from 2.2 per cent to 2.1per cent, insisting policy distortions and stagnant oil production levels limit investments in Nigeria.

A World Bank report had ranked Nigeria at the bottom of a chart showing the economic progression of countries.

The country was ranked at the bottom alongside Angola, South Africa and 16 other countries in a classification of growth performance included in the 14th edition of Africa’s Pulse.

The countries were said not to have shown any progress in their growth performance.

“These countries did not show any progress in their economic performance from 1995–2008 to 2015–18,” the report read.

The report by the World Bank further explained that; “The taxonomy compares the average annual Gross Domestic Product GDP growth rates during 1995–2008 and 2015–18 against predetermined thresholds.

“These thresholds correspond to the bottom and top terciles of the annual average growth rates across 44 Sub-Saharan African countries between 1995 and 2008 (that is, 3.5 and 5.4 per cent, respectively).

“If a country’s economic performance declined from 1995–2008 to 2015–18, the country is categorized in the bottom tercile, which includes “falling behind” and “slipping.”

“If a country’s growth rate remained invariant over time, between 3.5 and 5.4 per cent in both periods, it is categorized in the middle tercile (or “stuck in the middle”).

“If a country’s economic performance improved from 1995–2008 to 2015–18, with a growth of more than 5.4 per cent per year, the country is categorized in the top tercile, which includes the “improved” and “established” groups.”

The World Bank also maintained that the policy distortions and stagnant oil production levels limit investments in Nigeria and went ahead to cut Nigeria’s growth projection from 2.2 per cent to 2.1per cent.

“Growth in Nigeria is projected to rise from 1.9 per cent in 2018 to 2.1 per cent in 2019 (0.1 percentage point lower than last October’s forecast),” the Bretton Wood institution said.

“This modest expansion reflects stagnant oil production, as regulatory uncertainty limits investment in the oil sector, while non-oil economic activity is held back by high inflation, policy distortions, and infrastructure constraints.

“Growth is projected to rise slightly to 2.2 percent in 2020 and reach 2.4 per cent in 2021, as improving financing conditions help boost investment.

“In Nigeria, although the manufacturing and non-manufacturing PMIs remained above the neutral 50-point mark—which denotes expansion—they fell further in February, due to weaker rises in output and new sales orders across firms.

“Household consumption in Nigeria has remained subdued, while multiple exchange rates, foreign exchange restrictions, low private sector credit growth, and infrastructure constraints have continued to weigh on private investment.”
