The banking sector is one of the principal foundations of Jordan's economy. Despite the unrest and economic difficulties in the Arab world resulting from the Arab Spring uprisings, Jordan's banking sector maintained its growth in 2014. The sector consists of 25 banks, 15 of which are listed on the Amman Stock Exchange. Amman is the base city for the international Arab Bank, one of the largest financial institutions in the Middle East, serving clients in more than 600 branches in 30 countries on five continents. Arab Bank represents 28% of the Amman Stock Exchange and is the highest-ranked institution by market capitalization on the exchange.
