We know that S^(ZD/SGD) = S^(S/SGD) x S'(NZD/S) = .6135 times 1.3751 = .8436. By taking the reciprocal, 1/S^(NZD/SGD) = S"(SGO/NZD) = 1.1854. So, S^(NZD/SGD) = S^S/SGD) x S^(NZD/S) = .6140 times 1.3765 = .8452. The reciprocal, 1/S^(NZD/SGD) = S^(SGD/NZD) = 1.1832. Thus, the NZD/SGD bid-ask spread is NZD0.8436-NZD0.8452 and the SGD/NZD spread is SGD1.1832-SGD1.1854 Given the following quotations and find out if there is any arbitrage opportunity.
