Over the last several weeks, the dollar's depreciation
against the euro and yen has grabbed global attention. In a normal
world, the dollar's weakening would be welcome, as it would help the
United States come to grips with its unsustainable trade deficit.
But, in a world where China links its currency to the dollar at an
undervalued parity, the dollar's depreciation risks major global
economic damage that will further complicate recovery from the current
worldwide recession.
