See my article "An End to Currency Manipulation" in the Far Eastern Economic Review. The first paragraph:
The U.S. dollar last week appeared mercifully to end its plunge. World markets cheered, and the immediate financial crisis in the U.S. abated. But this week the dollar is retesting all-time lows versus the euro and yen, and commodity prices, capital flows, and trade remain vulnerable to its movements. Inflation in dollar-linked China is rising fast, and an over-strong yen could thwart Japan's recent recovery after its painful 1990s deflation. In the U.S., currency swings are destabilizing the economy and fueling anti-trade populism. After a decade of wild instability, it's time to rethink global currency markets and monetary policies.
