A proposed Currency Convertibility Fund,backstopped by a contingent credit from the InternationalDevelopment Association (IDA)-the World Bank'sconcessionary window for the world's poorestcountries-has been designed for the Songo Songo GasDevelopment and Power Generation Project in Tanzania. Thefund is a transitional mechanism aimed at supporting theTanzanian government's efforts to attract foreignequity in circumstances where the private sector perceives ahigh level of risk and is otherwise unwilling to invest. Thefund may be a replicable mechanism that, by mitigatingsovereign risks that investors are unwilling to bear andunable to hedge against, could help catalyze foreign equityinvestment in other IDA countries and in projects thatgenerate local currency.
