“Pick your battles,” seems to be the mantra that Jean-Claude Trichet, President of the European Central Bank (“ECB”), is currently living by.  While the Euro is slowly inching closer to record levels against the USD, Trichet has largely been content to focus his energy on a different nagging currency: the Japanese Yen.  Trichet has invoked the phrase “two-way risks” in cautioning investors to beware the enormous potential upside of the Yen.  Trichet realizes that the Japan-EU interest rate differential, manifested through the carry trade, is responsible for the diverging Euro-Yen exchange rate.  Ultimately, it remains unclear whether the EU will continue to limit itself to rhetoric in the battle to hold down the Euro, or whether it will use more heavy-handed tactics.  Forbes reports:

“We believe the Japanese economy is on a sustainable path and that foreign exchange rates should reflect that,” Trichet said.
