Chen ’s underlying short position in Singapore dollars is exposed to considerable currency
risk. If the range of spot rates is from $0.5774/S$ to $0.6255/S$, as in Scenarios # 2 and #3, then
the range of dollar obligations is $481,000 ( from- $5,774,000 to -$6,225,00 ) on the underlying
exposure in the spot market. This risk arises from variability in the level of the exchange rate.
