 AED and SAR currency exchange rates are each pegged to the USD, hence their interest rate swap markets are highly correlated to the US interest rate swap market respectively.e.g.if the SAR IRS Spread for a 5-year maturity is quoted as +150 basis points and the USD 5 year IRS fixed rate is trading at 1.00%, where the IRS fixed payments are annual and the floating payments are quarterly LIBOR, then the SAR 5 year IRS fixed rate will be 2.50%.
