The hydrocarbons sector is the backbone of the economy, accounting for roughly 60% of budget revenues, 30% of GDP, and over 95% of export earnings. Algeria has the seventh-largest reserves of natural gas in the world and is the second-largest gas exporter; it ranks 14th in oil reserves. Economic policy reforms supported by the IMF and debt rescheduling from the Paris Club in the past decade have helped improve Algeria's financial and macroeconomic indicators. Because of sustained high oil prices in the past three years, Algeria's finances have further benefited from substantial trade surpluses and record foreign exchange reserves. Real GDP has risen due to higher oil output and increased government spending. The government's continued efforts to diversify the economy by attracting foreign and domestic investment outside the energy sector, however, has had little success in reducing high unemployment and improving living standards. Structural reform within the economy moves ahead slowly.
