In the last few years Jordan's economic growth has slowed, averaging around 2%. Jordan's total foreign debt in 2011 was $19 billion, representing 60% of its GDP. In 2016, the debt reached $35.1 billion representing 93.4% of its GDP. This substantial increase is attributed to effects of regional instability causing: decrease in tourist activity; decreased foreign investments; increased military expenditure; attacks on Egyptian pipeline supplying the Kingdom with gas; the collapse of trade with Iraq and Syria; expenses from hosting Syrian refugees and accumulated interests from loans. According to the World Bank, Syrian refugees have cost Jordan more than $2.5 billion a year, amounting to 6% of the GDP and 25% of the government's annual revenue. With the presence of Syrian refugees in Jordan, wage growth went considerably down as a result of competition for jobs between refugees and Jordan citizens. The downturn that began in 2011, continued to 2018. The country's top five contributing sectors to GDP, government services, finance, manufacturing, transport, and tourism and hospitality were badly impacted by the Syrian civil war. Foreign aid covers only a small part of these costs, 63% of the total costs are covered by Jordan. An austerity programme was adopted by the government which aims to reduce Jordan's debt-to-GDP ratio to 77% by 2021. The programme succeeded in preventing the debt from rising above 95% in 2018.
