The main cash crop is coffee, which accounted for some 50% of exports in 2003. This dependence on coffee has increased Burundi's vulnerability to fluctuations in seasonal yields and international coffee prices. Coffee processing is the largest state-owned enterprise in terms of income. Although the government has tried to attract private investment to this sector, plans for the privatization of this sector have stalled. Efforts to privatize other publicly held enterprises have likewise stalled. Other principal exports include tea, sugar, and raw cotton. Coffee production, after a severe drop in 2003, returned to normal levels in 2004. Revenues from coffee production and exports are likewise estimated to return to pre-2003 levels.

Little industry exists except the processing of agricultural exports. Although potential wealth in petroleum, nickel, copper, and other natural resources is being explored, the uncertain security situation has prevented meaningful investor interest. Industrial development also is hampered by Burundi's distance from the sea and high transport costs. Lake Tanganyika remains an important trading point. The trade embargo, lifted in 1999, negatively impacted trade and industry.

Burundi is heavily dependent on bilateral and multilateral aid, with external debt totaling $1.2 billion in 2003. A series of largely unsuccessful 5-year plans initiated in July 1986 in partnership with the World Bank and the International Monetary Fund (IMF) attempted to reform the foreign exchange system, liberalize imports, reduce restrictions on international transactions, diversify exports, and reform the coffee industry.

IMF structural adjustment programs in Burundi were suspended following the outbreak of the crisis in 1993; the IMF re-engaged Burundi in 2002 and 2003 with post-conflict credits, and in 2004 approved a $104 million Poverty Reduction and Growth Facility loan. The World Bank is preparing a Transition Support Strategy, and has identified key areas for potential growth, including the productivity of traditional crops and the introduction of new exports, light manufactures, industrial mining, and services. Both the IMF and the World Bank are assisting the Burundians to prepare a Poverty Reduction Strategy Paper. Serious economic problems include the state's role in the economy, the question of governmental transparency, and debt reduction.

Burundi was not eligible for trade benefits under the African Growth and Opportunity Act in 2003.

To protest the 1996 coup by President Buyoya, neighboring countries imposed an economic embargo on Burundi. Although the embargo was never officially ratified by the UN Security Council, most countries refrained from official trade with Burundi. Following the 1996 coup, the United States suspended all but humanitarian aid to Burundi. The regional embargo was lifted on January 23, 1999, based on progress by the government in advancing national reconciliation through the Burundi peace process.
