One of the stranger attempts to apportion blame for the international financial crisis has been the claim that China is allegedly saving too much. A brief consideration of economic fundamentals will show the economic incoherence of this view.
Consider first China’s domestic situation. China requires a high savings rate in order to finance its high level of investment. As the evidence shows that the most important determinant of the rate of economic growth is the rate of increase of investment and labour, if China were to cut its rate of investment its economy would grow less rapidly. Furthermore, China’s growth is responsible for the majority of the reduction of the number of people living in poverty in the world. Reduction of China’s rate of investment, which in turn requires a high savings rate, would therefore result in China’s economy growing less rapidly, the world economy growing less rapidly, and world poverty shrinking less rapidly - clearly nothing positive lies down that road either for China or for anyone else. On the contrary, as the Indian Prime Minister has stressed countries such as India and China require high savings rates.
Internationally what is normally argued by the ‘China is saving too much’ view is that the key issue is to reduce China’s balance of payments surplus – the latter being statistically necessarily equal to China’s surplus of domestic savings over domestic investment. A case can be certainly be made that China should utilise a higher proportion of its savings domestically. Investment in the domestic Chinese economy would almost certainly earn a better rate of return than the present situation of large scale purchases of US Treasury Bonds. It might also lead to more rapid economic growth by China. The latter however depends on other factors as well - for example, prior to the financial crisis last year China’s economy was in danger of overheating and encouraging a higher level of investment would have exacerbated this. But a high investment level is certainly a means by which China's balance of payment surplus could be reduced.
But what would be the consequence of China reducing its balance of payments surplus in the present circumstances – whatever the means chosen? China recirculates its surplus in large part through purchase of US Treasury Bonds – that is, China adds to international savings. Reduction in China’s balance of payments surplus, unless compensated for by an increase in savings elsewhere, would inevitably lead to a rise in interest rates as the international supply of savings shrank – a likely form being a very direct increase in the interest paid on US Treasury Bonds. Such a rise in interest rates, under conditions of a world economic downturn, would be highly undesirable as so far there is no indication at all of an increase in the overall US savings rate that would compensate for a decrease in international saving by China. Such an increase in international interest rates would be economically contractionary when the opposite is what is required.
More fundamentally what choice did the increase in international savings by China offer to the US - and other economies? In essence it simply meant the US economy was able to borrow money at extremely low interest rates. That finance could have been used to rebuild the productive base of the US economy - that is, it could have been invested. That such finance available at low interest rates was not invested but was instead wasted in a consumer splurge was the result of economic policies pursued by successive US government not others. Others could have used such low interest rate finance for productive purposes.
An article in China Daily on 29 May by Lau Nai-keung put the issue in rather popular and polemical style with a distinct Asian emphasis - but he actually stated the question very accurately as regards economic fundamentals (incidentally rightly linking it to the need to raise investment for environmental reasons). Lau Nai-kueng is from Hong Kong.
’The [Chinese] government has decided to make domestic consumption the engine of sustained growth. But many people tend to confuse it with personal consumption...
‘On completing these tasks, the government can consider a free or highly subsidized transport system. Beijing’s example of subsidized subway transport is a good example of minimizing the risk of abuse in public service. Once a smooth and efficient public transport, which is free or subsidized, is in place, owning a car would only be a status symbol. The government can then think of scrapping hire purchase for cars so that fewer vehicles are on the streets. That will not only ensure a freer flow for public transport vehicles, but also mean reduced greenhouse gas emission...'Before the  Asian financial crisis, credit cards were not very common in South Korea. But after that, credit cards were dished out on the pretext of boosting consumption, and transformed almost the entire country into a group of ruthless spenders. The savings rate of South Koreans has dropped drastically, and as a result the country is now finding it difficult to weather the global economic storm.
‘In the US, most people are... spending money they have not earned. Ironically the economic crisis has forced people to rely even more on credit cards to maintain their lifestyle... Outstanding payment for credit cards worldwide is estimated to be more than $1 trillion and rising. Like subprime loans, card payments are also packaged in different kinds of derivatives, and when bad loans pile up, as is inevitable, another wave of financial tsunami will lash the global economy.‘We have to learn to make good use of our high savings rate, instead of encouraging the middle class to buy more houses and cars, and spend like there is no tomorrow. Most of the suggested measures does not require a lot of resources to implement and, in fact, will reduce pollution. On the contrary, they will help create quality employment and generate solid GDP growth.
‘When welfare schemes make people feel more secure, they would be more willing to spend. The social and economic infrastructure will also ensure sustained economic growth. Proper channelling of savings into investment and social spending will enhance real private consumption in the long run. Higher savings will then imply higher investment and, in turn, higher GDP and a more robust growth. Without proper savings, a high private consumption rate will lead to disaster, as has been the case in many Western countries.‘If a high savings rate is as bad as many Western economics would like us to believe, then how come we have succeeded and they have failed to weather the economic storm?’
The last sentence would seem to hit the nail rather accurately on the head.
