sukuk el-tamwil
n.— «Egyptian civil law limits the interest on a conventional bond to 7 per cent. This would hardly attract investors, with inflation running at over 30 per cent. However, Law 146 allows for the issue of sukuk el-tamwil, instruments similar to bonds, on which there is theoretically no restriction as regards the return offered. » —“MEED Special Report—Privatisation” Middle East Economic Digest (Market Harborough, England) June 8, 1990.
