Hi,
Can somebody please help me understand the following question please in layman terms
Japanese yen trades at $.00811.
Us RFR= 5.5% JPy RFR=3%
3month forward contracts quoted at $.00814
Indicate how you earn a riskfree profit by engaging in a forward contract.
OUTLINE your transaction (please explain this part in simple terms)

The first two points tell you what you need to do. The third one is a list of necessary transactions.
1) estimate fair price of foward contract:
F = S*(1+F)^t/(1+D)^t = $.00811*(1+3%)^.25/(1+5.5%)^.25=$0.00806
2) since forward is traded at a higher price, you should sell it and buy spot.
3) That would involve selling forward, borrowing money in the US, converting that amount to Japanese Yen, collecting interest rate, than sell Yen at $.00814 (delivering forward), paying back interest in the US, etc.
Does that help?作者: mp3bu 时间: 2011-7-11 19:38
the arbitrage free forward price is spot*(1+rfr$)^(3/12)/(1+rfr yen)^(3/12) = 0.00816
since the quoted forward price is lower, the yen is undervalued and hence you would buy forward yen (long yen)
if you are long yen, you would buy 1 yen 3 months from now through the forward contract
you could therefore borrow 0.99264 yen today at 3% rfr. the repayment would be 1 yen [0.99264*(1.03)^(3/12)] - 3 months from now. this can be repaid through the 1 yen you would be buying through the forward contract
0.99264 yen today can be converted to 0.99264*0.00811=$0.00805 at todays spot rate
invest $0.00805 at 5.5% for 3 months = 0.00805*(1.055)^(3/12) = $0.00816 - 3 months from now
of the $0.00816 you get 3 months later, use $0.00814 to purchase 1 yen through the forward contract and repay the 0.9926 yen borrowed at t(0) - repayment with interest = 1 yen
that leaves you with $0.00002 - arbitrage free profit
