I have been wondering lately if the sagging value of the dollar is actually going down through economic gyrations or being pushed down by design.

There are many repercussions. No one less than Rodrigo Rato, head of the International Monetary Fund, warned Monday of a potential "abrupt fall" in the US dollar that could roil the global economy. "There are risks that an abrupt fall in the dollar could either be triggered by, or itself trigger, a loss of confidence in dollar assets," Rato said at the close of annual meetings here of the IMF and the World Bank, according to news reports.

Here is what is really on his mind: Europe may take steps to temper the strong appreciation of the Euro, which is weighing on exports from the 13-nation bloc. "There is a risk that exchange rate appreciation in countries with flexible exchange rates -- including the Euro area -- could hurt their growth prospects, and that in these circumstances protectionist pressures could worsen," he said.

From my perspective I have wondered if the Bush administration is at least applauding the weak dollar as it improves U.S. trade imbalances, helps prop up the stock market and worried investment bankers, and strengthens American companies in many regards.
