Bahrain is one of the most diversified economies in the Persian Gulf. Highly developed communication and transport facilities make Bahrain home to numerous multinational firms with business in the Gulf. As part of its diversification plans, Bahrain implemented a Free Trade Agreement (FTA) with the US in August 2006, the first FTA between the US and a Gulf state. Bahrain's economy, however, continues to depend heavily on oil. Petroleum production and refining account for more than 60% of Bahrain's export receipts, 70% of government revenues, and 11% of GDP (exclusive of allied industries). Other major economic activities are production of aluminum - Bahrain's second biggest export after oil - finance, and construction. Bahrain competes with Malaysia as a worldwide center for Islamic banking and continues to seek new natural gas supplies as feedstock to support its expanding petrochemical and aluminum industries. Unemployment, especially among the young, is a long-term economic problem Bahrain struggles to address. In 2009, to help lower unemployment among Bahraini nationals, Bahrain reduced sponsorship for expatriate workers, increasing the costs of employing foreign labor. The global financial crisis caused funding for many non-oil projects to dry up and resulted in slower economic growth for Bahrain. Other challenges facing Bahrain include the slow growth of government debt as a result of a large subsidy program, the financing of large government projects, and debt restructuring, such as the bailout of state-owned Gulf Air.
