■ Intercurrency Spreads
Conceptually, intercurrency spreads are identical to outright currency trades. After all, a net long or short currency futures position is also a spread in that it implies an opposite position in the dollar. For example, a net long Japanese yen (JY) position means that one is long the JY versus the U.S. dollar (USD). If the JY strengthens against the USD, the long JY position will gain. If the JY strengthens against the Swiss franc (SF) and euro but remains unchanged against the USD, the long JY position will also remain unchanged.

The long JY/short euro spread is merely the combination of a long JY/short USD and a long USD short euro position, in which the opposite USD positions offset each other. (To be precise, the implied USD positions will only be completely offset if the dollar values of the JY and ...
