Spain ceded Guam to the US in 1898. Captured by the Japanese in 1941, it was retaken by the US three years later. The military installations on the island are some of the most strategically important US bases in the Pacific; they also constitute the island’s most important source of income and economic stability.

US national defense spending is the main driver of Guam’s economy, followed closely by tourism and other services. Guam serves as a forward US base for the Western Pacific and is home to thousands of American military personnel. Total federal spending (defense and non-defense) amounted to $1.988 billion in 2016, or 34.2 of Guam’s GDP. Of that total, federal grants and cover-over payments amounted to $3444.1 million in 2016, or 35.8% of Guam’s total revenues for the fiscal year. In 2016, Guam’s economy grew 0.3%. Despite slow growth, Guam’s economy has been stable over the last decade. National defense spending cushions the island’s economy against fluctuations in tourism. Service exports, mainly spending by foreign tourists in Guam, amounted to over $1 billion for the first time in 2016, or 17.8% of GDP.
