 Hey, if you weren't following the news, a big hit to the U.S. dollar just came in June when Saudi Arabia didn't renew its petrodollar deal with the U.S. Since 1974, the Saudis have sold oil largely in U.S. dollars. That was big for our global economic dominance. Now they want other options, well, other than the U.S. dollar. So it's a pretty simple supply and demand. If there's less demand for the U.S. dollar, well, what happens?
