Tourism, petroleum bunkering, hospitality, and financial and business services are the mainstays of the small open Aruban economy. Tourist arrivals have rebounded strongly following a dip after the 2008 global financial crisis. Tourism now accounts for over 80% of economic activity. Over 1.5 million tourists per year visit Aruba, with 75% of those from the US. The rapid growth of the tourism sector has resulted in a substantial expansion of other activities. Construction continues to boom with hotel capacity five times the 1985 level. Aruba is heavily dependent on imports and is making efforts to expand exports to achieve a more desirable trade balance. Almost all consumer and capital goods are imported, with the US, the Netherlands, and Panama being the major suppliers. Aruba weathered two major shocks in recent years: fallout from the global financial crisis, which had its largest impact on tourism, and the closure of its oil refinery in 2009. However, tourism and related industries have continued to grow, and the Aruban government is working to attract more diverse industries. Aruba's banking sector withstood the recession well, and unemployment has significantly decreased.
