Over the past several weeks, the US dollar's depreciation against the euro and yen has grabbed global attention.
In
a normal world, a weaker US dollar would be welcome, as it would help
the US come to grips with its unsustainable trade deficit.
But
because China links its yuan to the US dollar at an undervalued parity,
the US dollar's depreciation risks major global economic damage,
complicating the recovery from the worldwide recession.
