In het artikel hier op ForexNews kwam het al te sprake: Voorlopig geen chinese currency in online valuta handel
Om te kijken of een currency ondergewaardeerd is wordt ook wel gebruik gemaakt van de zogenoemde BigMac-index. In ieder land is er wel een MacDonalds te vinden. Aan de hand van de prijs hiervan in dat land wordt de BigMAc-index bepaalt. Zie de grafiek en kijk maar eens naar China.

The Big Mac index

Our Big Mac index shows the Chinese yuan is still undervalued

Mar 17th 2010 | From The Economist online

Correction to this article

RECENT renewed American calls for China to revalue its currency have so far fallen on deaf ears. China has rejected accusations that America's huge trade deficit with it is caused largely by an artificially weak yuan, which has been pegged to the dollar since July 2008. Economists point out that an appreciation of the yen did little to help reduce America's trade deficit with Japan in the 1980s. But the yuan is unquestionably undervalued. Our Big Mac index, based on the theory of purchasing-power parity, in which exchange rates should equalise the price of a basket of goods across countries, suggests that the yuan is 49% below its fair-value benchmark with the dollar.

Nog een goed argument voor Geithner: "Look, if you guys continue to keep the price of a big mac artificially low, you'll all end up as little yellow obese matzo balls." (to assistant: "can you still say matzo balls? Or is it considered a racial slur." assistant: "slur sir" )

"I mean, yellow pingpong balls."
