The Dollar Index is creeping up on an important resistance — a peak recorded in January at 92.64 just before the dollar went into a steep dive. If this daunting impediment gives way easily and is exceeded by more than 15 to 20 cents over the next day or two, it would presumably re-energize buyers for an even bolder next push. The most important resistance on the chart shown lies at 95.15, where the dollar made a double top last autumn. Once above it, DXY would be hard to stop.  This could hold drastic implications for the U.S. and global economies.  Chief among them would be the pressure it would put on all who owe dollars, and on foreigners who buy U.S. goods.  For a big-picture view, check out the DXY tout at the bottom of the list.
