There’s a lot of talk around the markets and in Washington about China’s currency policy. What many want to know is whether the US Treasury will name China as a currency manipulator. Perhaps a more important question is, should China be named as a currency manipulator? And if it were named as such, what actions could the US take? In recent days the Chinese and the US administration have taken shots in the press at each other. The US is hinting that China is manipulating its currency to boost its economy. The Chinese is firing back saying that the US “should not politicize the remnimbi exchange rate issue.”

First, some background on the problem. Basic economics says that if you keep the currency of your country at a weak (but not so weak as to cause a collapse in it) level you help boost exports. The currency becomes weaker making your goods cheaper for foreign consumption. In a freely floating exchange system, the market determines the equilibrium value. Speculators look at economic statistics like GDP growth, interest rates, inflation etc. to figure out what a currency should be worth and then place bets accordingly. If speculators think that an economy can grow strongly while keeping inflation at a benign rate, they will bid up the currency of that economy. As that happens, the country whose currency is getting stronger could see a decrease in exports. This is caused by the larger amount of currency the importer uses to make the same purchase as previously made. (more…)
