The U.S. Dollar Index fell during the week and is drawing dangerously close to last December's low (green circle). The foreign currency with the biggest influence on the USD is the Euro. Expectation for continuing economic strength in Europe – and the likelihood for further ECB rate hikes – pushed the Euro (blue line) to a new two-year high against the dollar. The weekly bars in Chart 2 show the Euro (blue line) moving up to challenge its late 2004 peak near 136. A close above that chart barrier would increase the odds for the USD to threaten its corresponding low near 80. That would be a very important test for the U.S. currency.
