The World Bank expected that growth in the Middle East and North Africa region to recover modestly to a 3.1 percent pace this year, with oil importers registering the strongest gains. 

Among oil exporters, Saudi Arabia is forecast to accelerate modestly to a 1.6 percent growth rate in 2017, while continued gains in oil production and expanding foreign investment are expected to push up growth in Iran to 5.2 percent. The forecast is based on an expected rise in oil prices to an average of $55 per barrel for the year, the World Bank said in a report.

The report analyzes the worrisome recent weakening of investment growth in emerging market and developing economies, which account for one-third of global GDP and about three-quarters of the world’s population and the world’s poor. Investment growth fell to 3.4 percent in 2015 from 10 percent on average in 2010, and likely declined another half percentage point last year.

Slowing investment growth is partly a correction from high pre-crisis levels, but also reflects obstacles to growth that emerging and developing economies have faced, including low oil prices (for oil exporters), slowing foreign direct investment (for commodity importers), and more broadly, private debt burdens and political risk.

“We can help governments offer the private sector more opportunities to invest with confidence that the new capital it produces can plug into the infrastructure of global connectivity,” said World Bank Chief Economist Paul Romer. “Without new streets, the private sector has no incentive to invest in the physical capital of new buildings. Without new work space connected to new living space, the billions of people who want to join the modern economy will lose the chance to invest in the human capital that comes from learning on the job.”

Emerging market and developing economy commodity exporters are expected to expand by 2.3 percent in 2017 after an almost negligible 0.3 percent pace in 2016, as commodity prices gradually recover and as Russia and Brazil resume growing after recessions.
