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.
