While the use of risk-sharing instruments for the funding of revenue-generating infrastructure projects is easy to understand, such instruments can also be used for the funding of non-revenue generating infrastructure. The principle of risk-sharing would require that the government's repayment of the obligation created be linked to some proxy or indicator of government revenue. Given today's conundrum with debt and the need to deleverage, GDP-linked securities are being revisited. Replacing the benchmark to LIBOR (London Interbank Offer Rate) with a benchmark to nominal GDP makes eminent sense, especially from a Shariah viewpoint.
