Suppose you work at the FOREX desk of a multinational bank. No particular country is the home country for you as your responsibility is to conduct foreign exchange trade in whichever way is profitable for the bank. Using this as your guideline, consider the following data:

S0 = ¥92/US$

S180 = ¥92/US$

IUS = 2% per annum

IJapan = 0.09% per annum

With a starting amount of US$10 million or its Yen equivalent, can you make a UIA profit? What if a CIA was conducted at F180 of ¥90/US$? What are your observations?
