forex swap

Hi john, you have mentioned that i can't post a textbook question, therefore i have changed the company names of the question, and even the verbs and the amount.( i really can't understand this one part, so i really need your help...) The question is we assume that a company called ACY Ltd need an initial investment of 200m won and it will be sold for 300m won in one year's time. The currency spot rate is 40 won per sgd(singapore dollar) and government has offered a forex swap at 40 won per sgd. ACY Ltd can't borrow won directly and no forward market is available. The estimated spot rate in one year is 80 won per sgd and the current singapore borrowing rate is 20%. In the answer sheet, it is with forex swap - Buy 200m won at 40 - swap 200m won back at 40 - sell 200m won at 80 - interest on singapore loan ( 5mx 20%) My question is that when, they buy at 200m won at 40, is this(40) the currency spot rate ? or the forex swap rate (and why is it ) ? i stand on spot rate because we only consider swapping rate when we actually swap and swap back the currency not for buying the loan.
