Strangely enough, the dollar has strengthened against major currencies like the Pound and the Euro (1.49 down to 1.4450) as the big boys think the dollar will be a safer bet than the other currencies when the global economy blows.
In the mean time, money would bail out of the overseas markets in trouble and head for U.S. market which may not been yet hit in full-force.
It will go down nearly at the end. Then everybody will be pancaked in U.S. market.
