A feature in the marketplace Thursday is weakness in secondary market currencies versus the U.S. dollar. The Argentine peso hit a record low against the greenback and the Turkish lira is also under pressure. The Brazilian real and Indian rupee are also solidly lower against the dollar. As the calendar turns to September next week, look for focus on secondary currencies and their countries’ problematic debt loads to become in keener focus among traders and investors. Such should continue to support gains in the U.S. dollar index, which has seen a corrective pullback this week.
