The island nation has been able to attract foreign business and investment, especially in its offshore banking and tourism industries. Tourism is Saint Lucia's main source of jobs and income - accounting for 65% of GDP - and the island's main source of foreign exchange earnings. The manufacturing sector is the most diverse in the Eastern Caribbean area. Crops such as bananas, mangos, and avocados continue to be grown for export, but St. Lucia's once solid banana industry has been devastated by strong competition and by Hurricane Tomas in 2010. Saint Lucia is vulnerable to a variety of external shocks, including volatile tourism receipts, natural disasters, and dependence on foreign oil. Furthermore, high public debt - 77% of GDP in 2012 - and high debt servicing obligations constrain the ANTHONY administration's ability to respond to adverse external shocks. St. Lucia has experienced anemic growth since the onset of the global financial crisis in 2008, largely because of a slowdown in tourism. As airlines cut back on their routes to St. Lucia in 2012, tourism growth slowed. Also, St. Lucia introduced a value added tax in 2012 of 15%, becoming the last country in the Eastern Caribbean to do so.
