Tanzania is one of the world's poorest economies in terms of per capita income, but has achieved high growth rates based on its vast natural resource wealth and tourism. GDP growth in 2009-14 was an impressive 6-7% per year. Tanzania has largely completed its transition to a market economy, though the government retains a presence in sectors such as telecommunications, banking, energy, and mining. The economy depends on agriculture, which accounts for more than one-quarter of GDP, provides 85% of exports, and employs about 80% of the work force. The World Bank, the IMF, and bilateral donors have provided funds to rehabilitate Tanzania's aging infrastructure, including rail and port, that provide important trade links for inland countries. Recent banking reforms have helped increase private-sector growth and investment, and the government has increased spending on agriculture to 7% of its budget. The financial sector in Tanzania has expanded in recent years and foreign-owned banks account for about 48% of the banking industry's total assets. Competition among foreign commercial banks has resulted in significant improvements in the efficiency and quality of financial services, though interest rates are still relatively high, reflecting high fraud risk. All land in Tanzania is owned by the government, which can lease land for up to 99 years. Proposed reforms to allow for land ownership, particularly foreign land ownership, remain unpopular. In 2013, Tanzania completed the world's largest Millennium Challenge Compact grant, worth $698 million, and in December 2014 the Millennium Challenge Corporation selected Tanzania for a second Compact. Dar es Salaam used fiscal stimulus and loosened monetary policy to ease the impact of the global recession. In late 2014 a highly publicized scandal in the energy sector involving senior Tanzanian officials resulted in international donors freezing nearly $500 million in direct budget support to the government.
