There are a lot of people found them confused with the theory that it was Chinese “saving glut” that helped produce the Financial Crisis, and also there are a few misconceptions about this argument. IMO, this argument is not wrong but to simply say things like “Chinese savings finance the American bubble” actually unconsciously ignores some important features of the system of “Chimerica” (aka Bretton Woods II). Here I want to sum up the monetary relationship between these two countries, let’s start with :
Here in , the elites set GDP as their primary concern, and to achieve the goal of maintaining a high rate of growth (we usually have 8 percent of increase in GDP per year), it is crucial to keep the exporting industry rolling, thus building up a large foreign reserve with it.
The process of building up a reserve is like this: The exporting industry always receives substantial revenues, and it has to be realized that these revenues are in Federal Reserve Notes, aka dollars, not RMB, because the money you Americans use to buy imported products from is dollar. Then, those exporters have to give all the revenues, which are dollars, to the People’s Bank of China, (PBC) aka the Chinese Central Bank, because it is mandatory to do so. This requirement imposed on the exporting industry is not unacceptable because the exporters can’t use US dollars in Chinese economy anyways. (A few years ago, this requirement is abandoned, meaning that the exporters are allowed to save their dollars in their bank accounts) Therefore, the foreign reserve is built, through collecting the dollars from the exporting industry. The crucial concept is that the PBC will offer the amount of RMB that is equal to the dollars an exporter handed in for the exporter. As an example, if a firm received 100000 dollars as revenue received from exporting goods for the Americans, it has to give 100000 dollars to the PBC, and then receive 700000 RMB from the PBC. (Let’s assume that one Federal Reserve Notes equals to seven RMB) Therefore, the very essence of this system of Chimerica is that in order to build up a super huge foreign reserve, the PBC must ensure its capacity to offer the same amount of currency, this time in RMB, back for the exporting industry.
The PBC decides to use those newly collected dollars do something, and they are used to purchase American bonds, a large proportion of which are Treasury Bills. There are two reasons why we do this: First, purchasing the Treasury Bills (and other bonds) is just like getting the dollars out of the international market, therefore exerting an appreciation pressure on the dollar, as well as a depreciation pressure on the RMB against dollar. It is known that country A with too much exporting to country B just makes its currency rise steeply against the currency of country B, and the appreciation will hurt country A’s exporters. wants to keep a very strong exporting industry, so PBC finds itself obligated to preventing the appreciation of RMB against the Dollar, and purchasing American Treasury Bills is certainly pretty helpful. And the purchasing of these bonds is probably what some Americans refer to when they blame us for “manipulating currency”. Second, Treasury Bills are seen by PBC as the safest and most stable type of purchasing foreign assets. PBC somehow purchases some sub mortgage assets, too, from Freddie Mac and Fannie Mac. The purchasing of the Treasury Bills and other assets is undoubtedly one major factor responsible for the low interest rate of Federal Reserve and low interest rate of other assets. (e.g. sub mortgage bonds) because quite obviously the more funds collected (through Treasury Bills) available for Federal Reserve, the more incentives for the Federal Reserve to lower the interest rate to lend the money out.
Thus, it has to be noted that it was our savings that create the POTENTIAL for PBC to offer the money for the exporters in order to collect the dollars for its reserves, and it was the use of the reserve of dollars to purchase Treasury Bills that generally ensure the interest rate low for the American investors to pop up the debt-bloated super economy.
Ps, about “exporting deflation” and “importing inflation”: by artificially maintain a weak RMB against Dollar, the PBC ensure that the exporters can keep making a lot of money in their business, meaning that large amount of dollars are taken out of American economy to our exporters. This feature is “exporting deflation”. In fact, I think the Fed must want this deflationary pressure, because it leaves more room for it to keep a very low interest rate. A large amount of dollars collected therefore is actually a source of inflation because the same amount of RMB has to be given to the exporters, thus increasing the money supply of Chinese economy.
Having explained all this, I have to say that yes, our savings are a key factor responsible for the economic crisis in an indirect way, but we are not the only one very guilty for it. If not for the Fed forever printing money out of thin air and the US Government unstoppably encouraging a debt-bloated structure of American economy, the American buyers would not have such a strong desire to buy, and therefore China would not be too induced to keeping her exporting industry rolling, thus eliminating of the vicious cycle of Chimerica at the very beginning.
Hope this explanation will help you out, but any mistakes in the above explanation pointed out will be greatly appreciated, I am a beginner.
