Sylvia is a foreign exchange dealer for a bank in London. She has 2,000,000 (or its Singapore dollar equivalent) for a short-term money market investment. She wonders if she should invest in pounds sterling or make a covered interest arbitrage investment in the Singapore dollar. The following information were given:

Spot exchange rate SGD/GBP 0.4816/S$

90-day forward rate SGD/GBP 0.4803/S$
