transfer companies. The latter include Dahabshiil, Qaran Express, Mustaqbal, Amal Express, Kaah Express, Hodan Global, Olympic, Amana Express, Iftin Express and Tawakal Express. Most are credentialed members of the Somali Money Transfer Association (SOMTA), an umbrella organization that regulates the community's money transfer sector, or its predecessor, the Somali Financial Services Association (SFSA). Somalia is the world's fourth-most country dependent on remittances. Most remittances are sent by Somalis-based abroad to relatives in Somalia. This accounts for 20%-50% of the Somali economy. Dahabshiil is the largest of the Somali money transfer operators (MTO), having captured most of the market vacated by Al-Barakaat. The firm has its headquarters in London and employs more than 2000 people across 144 countries, with 130 branches in the United Kingdom alone, a further 130 branches in Somalia, and 400 branches globally, including one in Dubai. The company provides a broad range of financial services to international organisations, as well as to both large and small businesses and private individuals. After Dahabshiil, Qaran Express is the largest Somali-owned funds transfer company. The firm has its headquarters in both London and Dubai, with 175 agents worldwide, 66 agents in Somalia and 64 in London, and charges nothing for remitting charity funds. Mustaqbal is the third most prominent Somali MTO, with 8 agents in Somalia and 49 in the UK. As with Dahabshiil and Qaran Express, it also has a notable presence internationally. As the reconstituted Central Bank of Somalia fully assumes its monetary policy responsibilities, some of the existing money transfer companies are expected in the near future to seek licenses so as to develop into full-fledged commercial banks. This will serve to expand the national payments system to include formal cheques, which in turn is expected to reinforce the efficacy of the use of monetary policy in domestic macroeconomic management. With a significant improvement in local security, Somali expatriates began returning to the country for investment opportunities. Coupled with modest foreign investment, the inflow of funds have helped the Somali shilling increase considerably in value. By March 2014, the currency had appreciated by almost 60% against the U.S. dollar over the previous 12 months. The Somali shilling was the strongest among the 175 global currencies traded by Bloomberg, rising close to 50 percentage points higher than the next most robust global currency over the same period.
