DUBAI - A record drop in oil prices, added to the coronavirus outbreak, has left the Middle East and North Africa more exposed than other regions to fallout from a possible global recession, the World Bank said.

Oil prices suffered their biggest one-day fall in nearly 30 years on Monday, after the unexpected collapse of a production agreement between Saudi Arabia, Russia and other major crude producers triggered a price war.

Meanwhile cases of the new coronavirus, COVID-19, are rising across the two regions. Iran is one of the global epicentres of the outbreak, with more than 8,000 cases and almost 300 fatalities, the health ministry said on Tuesday.

"As the world struggles with the fear of recession, the Middle East and North Africa could be the hardest hit by what is arguably a perfect storm: the coronavirus spreads to the region and oil prices collapse," the World Bank said in a briefing paper by Rabah Arezki, its chief economist for MENA, and a second economist, Rachel Fang.

All Gulf Arab states, which have economies heavily reliant on oil revenues, have recorded cases of COVID-19.

"If the decline in oil prices persists, it will erode the fragile macroeconomic and social stability of countries, especially in the Middle East and North Africa, that have been hit by the novel coronavirus," the brief said.

Oil prices jumped 10% on Tuesday, partly recovering from Monday's low, but they remain down over 40% since the beginning of the year as the epidemic dampens economic activity worldwide.

Income for Gulf oil-exporting states likely decline this year, while oil-importing countries in the Middle East will experience lower foreign direct investments, remittances and grants from exporters, said the World Bank.

It said Gulf countries that have accumulated ample financial wealth, should use it.

"Other oil-exporting countries, such as Algeria and Iran, are exhausting their buffers and will have to rely on flexible exchange rates to manage the current situation and conduct much-needed reforms in private-sector development and broader economic transformation."

Iran's rial currency has plunged. On Tuesday, the dollar was being offered at as much as 155,500 rials compared with its official rate of 42,000 rials, according to foreign exchange website Bonbast.com.
