In our year 2 IB Economics class, we are beginning the part of our International Trade unit on exchange rates and the balance of trade . While the market for a particular currency reflects many of the same characteristics as a product market (i.e. upward sloping su
pply curve, downward sloping demand curve), the consequences of a change the price of a currency (the exchange rate) is far more powerful than a change in the price of a particular good or service in a product market.
How does the value of a country’s currency affect that country’s balance of trade with other countries? To understand this important concept, we first need to know something about the process by which currencies are exchanged when two countries trade. Let’s look at an example:
When an American consumer wants to buy an iPod that was made in China she will have to pay for it in US dollars, since that’s what she earns her wages in from selling her labor in the resource market. Apple now has the consumer’s $300, which gets split up to cover all the costs the company faced in the manufacture, distribution, marketing and sale of the iPod. Part of that $300 (say $100) will go to the manager of the factory in China where it was made.
The factory manager in Shanghai faces his own costs he must cover. He must pay rent on his factory space, interest on the loans he took out to acquire capital, and wages to the workers assembling iPods on his factory floor. The problem is, these costs are all in Chinese yuan, but he’s holding the US dollars that Apple paid him for his iPod. In order to cover his costs, the Chinese factory owner must take the $100 to a Chinese bank and swap it for RMB. The local bank that changes his money now hands the $100 over to China’s central bank (the PBOC) which prints and exchanges RMB to the bank at whatever the prevailing exchange rate is at the time.
Ultimately, China’s central bank will decide what to do with its holding of US dollars. Most of the dollars are loaned back to the United States through China’s purchase of US Treasury securities (the IOUs the US government sells to finance its deficits). China’s voracious demand for US dollar denominated assets keeps the demand for (and the the value of) dollars high on foreign exchange markets, meaning the RMB remains relatively cheap for Americans and therefore Chinese manufactured goods attractive.
China’s policy of exchange rate manipulation has upset many American politicians over the years, who often blame China for America’s shrinking manufacturing sector. A weak RMB means the cost of producing things like iPods in China is far lower than it would be in the US. By keeping demand for dollars high on the foreign exchange markets through its incessant demand for US treasury securities and other financial and real assets, while simultaneously hoarding vast reserves of US dollars in its central bank, thus keeping supply of dollars on foreign exchange markets low (see graph), China has prevented the RMB from appreciating, fueling the growth of the country’s export-manufacturing sector.
China’s currency manipulations may soon ilicit a response from the United States as president-elect Barack Obama takes office next year. Facing a recession and rising unemployment, combined with the recent appreciation of the US dollar, the pressure is on Obama to take immediate action to restore America’s manufacturing sector. According to the Financial Times blog “the Economists’ Forum”:
If the US economy takes a downturn and the dollar continues to strengthen, a resurgence of protectionist pressures is likely. This time around, these pressures could well take the form of unilateral action against competitive currencies. It is noteworthy that President-elect Obama has actively and repeatedly supported action against “currency manipulation.”
The “competitive currency” perceived to pose the greatest threat to America’s inustrial sector is certainly the Chinese RMB. Currency manipulation is a form of protectionism, which in a time of global economic slowdowns poses a larger threat than ever to both developed and developing nations’ economies alike. For this reason, the World Trade Organization may need to employ carrot and stick methods to create incentives for China to liberalize its currency controls and allow the RMB to strengthan against the dollar and other major currencies:
How would this new rule against undervalued exchange rates be incorporated in the WTO? Through negotiation. The (WTO) should place rules on undervalued exchange rates…. The US and EU have been the principal demandeurs for action by China in the past. But it is important to remember that until very recently, a number of developing countries—Brazil, Mexico, Korea, Turkey and South Africa—were affected by the competitive pressure from the undervalued (RMB). Indeed, some months ago, the Indian Prime Minister urged China to follow a more market-based exchange rate policy. For obvious reasons, more emerging market countries have not voiced their concerns, but it is possible that a coalition of affected countries could unite on this issue.
Clearly, Chinese concerns have to be addressed for any new rules to be crafted and commonly agreed… First, China’s major trading partners could pledge granting China the status of a “market economy” in the WTO contingent on it eliminating currency undervaluation and moving to a market-based system. This status would have significant value for China by shielding it against unilateral trade actions such as anti-dumping and countervailing duties by trading partners. Second, as part of radical governance reform of the IMF, which is desirable in itself, China should be offered a substantially larger voting share in the IMF commensurate with its economic status.
Discussion Questions:
- How does China continuing to undervalue its currency threaten the industrial economies of its largest trading partners?
- What is China’s purpose for maintaining the low value of the RMB relative to the currencies of other nations?
- What would be a unilateral protectionist measure an Obama administration may advocate if the WTO refuses to take action against China’s currency manipulations? How would you advise president-elect Obama on the issue of whether to take protectionist action against China in the context of the current economic crisis in America?
