People who invest in highly rated securities from U.S. government-sponsored enterprises (GSEs) now have an alternative with a new bond program unveiled last month focused on supporting private sector development in emerging markets through triple-“A” rated bonds.

These securities, called Impact Notes, are the combined effort of the International Finance Corp., a member of the World Bank Group and the largest global development institution focused solely on the private sector in developing countries, and Incapital LLC, a leading underwriter and distributor of financial products.

IFC Impact Notes are five-year, non-call, six-month step-up callable notes, starting with 1% in year one and growing to about 4% in year five. The minimum purchase is $1,000 and they’re bought in $1,000 increments. Retail investors can purchase these notes from broker-dealers and wealth managers via the Incapital platform.

Louise Herrle, managing director of capital markets at Incapital, says Impact Notes can potentially offer comparable yields to triple-“A” rated U.S. GSEs such as Fannie Mae, Freddie Mac, Farm Credit and TVA. The difference is their focus on investing in private enterprises in more than 100 developing countries. Thus, they offer investors a fixed-income opportunity in the impact investing space.
