As a result of a November 1993 bilateral agreement, the Overseas Private Investment Corporation (OPIC) can assist US investors in the South African market with services such as political risk insurance and loans and loan guarantees. In July 1996, the US and South Africa signed an investment fund protocol for a $120 million OPIC fund to make equity investments in South and Southern Africa. OPIC is establishing an additional fund – the Sub-Saharan Africa Infrastructure Fund, capitalised at $350 million – to investment in infrastructure projects. The Trade and Development Agency also has been actively involved in funding feasibility studies and identifying investment opportunities in South Africa for U.S. businesses.
