In the past few years, the economy of São Tomé and Príncipe has grown, driven by agriculture, tourism and foreign investments, but mainly grew due to government spending driven by foreign loans. Gross domestic product (GDP) grew at an average rate of 5.5% between 2009 and 2017, but has slowed since 2014. The slowdown in economic growth was caused by lower government spending due to decreased foreign loans and decreased revenue government tax.
