China's devaluation dilemma: where next with the yuan, dollar and the euro?

The yuan is currently pegged to the US dollar in order to keep Chinese goods comparatively cheap in the key North American markets. As long as the US dollar is weak, the Chinese yuan is weak and therefore competitive in European markets. While complaints abound from the US about this "unfair" trade advantage, is it possible China has been blind-sided by the recent euro woes?

The US$-euro exchange rate is also a pillar to global trade. As the euro falls, countries are also under pressure to weaken their currencies. Specifically, China is under pressure to weaken its currency because Europe is the largest consumer of Chinese goods. In order to remain competitive, Chinese companies must reduce their profit margins or hope to make up reduced profits by increases in volume.

To weaken one's currency, one has to sell it and buy another currency. If you're China, would you rather sell the yuan to buy the euro, yen, or U.S. dollar? In this trio, the US dollar is king because it's the least worst scenario being the global reserve currency.

The Chinese government is now confronted with a policy dilemma because it has painted itself into a corner. Which exchange rate should it "manage" for the long term benefit of its export industries? It can either target the US$-yuan or the euro-yuan. It cannot aim for both as it has no influence over the US$-euro rate. As this chapter unfolds, distant images of how another major economic power blew up in the late 1980s with failed exchange rate targetting, from which it has never recovered, loom ever larger: Japan. This lack of control worries Chinese policymakers. This could be one reason why Chinese entrepreneurs have recently voiced their increasing concerns over their own government's US$-yuan policy. There are now bigger and wider issues at stake because entrepreneurs are not willing to invest in a climate of uncertainty.

Every country desires a weaker currency so it can export more goods. However, the only way to weaken one's currency is to sometimes make bad investments. Such economics make sense to a central banker: more exported goods mean more jobs, social cohesion and a higher GDP. So why would you fundamentally weaken your entire nation for one good year of exports? Imagine breaking all the windows in your city so that you will experience a building boom.

If market forces to allow the exchange rate to find their comfort levels are not the answer for China's zest for "control", then an alternative outlet needs to be created to protect the general Chinese investor community from the future vagaries of their export sectors. A safety valve that can stand the test of time. Precious metals are one such avenue.
