There are two reasons why concerns about a free fall of the dollar should not be worth consideration. The first is that the US external deficit will stay high only if US growth remains vigorous. But if the US continues to grow strongly, it will also retain a strong attraction for foreign capital, which should support the dollar. The second reason is that the attempts by the monetary authorities in Asia to keep their currencies weak will probably not work.
The fall of the dollar
The steady and orderly decline of the dollar from early 2002 to early 2004 against the euro, Australian dollar, Canadian dollar and a few other currencies (i.e., its trade-weighted average, which is what counts for purposes of trade adjustment), while significant, has still only amounted to about 10 percent.
