Begin by borrowing $1,000,000 at 7%, owing $1,070,000 at year end.

Convert the $1,000,000 to pounds at $1.75/L = L571,428.57 and invest this in London at 12% yielding L640,000 at year end. At the same time, sell the L640,000 forward at a rate of $1.68/L for delivery in one year yielding $1,075,200 at year end. At the end of the year, collect the L640,000 and deliver to the bank's foreign exchange dept. in return for $1,075,200. Repay the $1,070,000 from the $1,075,200 leaving a profit of $5,200.
