Saudi Arabia possesses approximately a quarter of the world’s oil reserves, and is the world’s leading oil producer and exporter. Oil revenues account for 90% of export earnings. Increased revenue from high oil prices has enhanced growth, raised government income, and fostered increasing capital investment, while enabling Riyadh to pay domestic debt and increase infrastructure expenditure. However, this dependence on oil harms the level of competitiveness in the economy as a whole, because it makes diversification difficult.
Much of the young population lack the education and technical skills the private sector needs. Mass education is weak, and on average Saudis have only 1.45 years of secondary education. At the elite level as well, a dearth of human capital severely limits levels of innovation, particularly in terms of the number of patents filed. The human capital weaknesses in turn create a reliance on foreign workers, particularly in the oil and service sectors.
The government exercises strong controls over major economic activities, which then suffer from the weaknesses in government effectiveness, as they use subsidies and other policies to distort domestic prices. However, accession to the World Trade Organization in 2005 has led to gradual economic reforms, and the Saudi government has sought to attract foreign investment to reduce dependence on oil revenues.
