laureth – “The size of its outstanding debt to the rest of the world makes the US vulnerable to pressure in global political matters. If, for example, China wanted to have its way on an important political issue, it could imply that it was going to reduce its dollar holdings due to lack of confidence in the currency. This kind of declaration would have hugely negative ramifications for the dollar and the US economy, and is something the US would be keen to avoid.
It is this fourth point that I wish to expand on. China is often seen as seen as the main threat to US domination in global politics due to its size, its economy and its military might. It now has a major bargaining advantage in its creditor status. Since China’s rise to prominence as a global economic power, its partial embrace of capitalist culture and its accession to the World Trade Organisation, there hasn’t really been a significant dispute with the US. But what if this were to change one day? In the same way that Russia has become more confident and more belligerent as its economic wealth has grown, China could also adopt a more aggressive stance towards the US.
In some ways the economic strength of the US and its influence on the world stage has been sold out from underneath it by the sale of so many Treasury bills. A country such as China, which holds 19% of all the T-bills in circulation, might be able to dictate terms to the US or else it could threaten to sell off its holdings under the auspices of diversification or lack of confidence. Whilst this would mean that the value of all China’s dollar-denominated foreign reserves were pummelled, it would ultimately survive. However, there would be a run on the US dollar and it would decimate the US economic system. In one single bound China could overtake the US as the world’s most important economy and as the world’s premier superpower.
If China were to sell its US dollar holdings at an accelerated rate, then the value of the dollar would collapse and interest rates would be forced up in order to support the currency. High interest rates would almost certainly send the US into a severe recession. It would also likely lose its triple-A credit rating which would exacerbate the problem. A stable currency is essential for any country to attract foreign investment and the dollar has been propped up for a long time by the continued purchases of T-bills by overseas investors, particularly China, due to the size of its holdings. It currently requires $2billion a day to finance the current account and if sovereign wealth funds stopped buying dollars the deficit could balloon to unmanageable proportions. America’s role as the greatest economic power in the world would be at an end.
Other holders of dollar-denominated assets, such as Japan and the OPEC members, would also suffer and they would certainly condemn China for taking such action. But are their concerns enough for China to pass up the chance of moving up the rankings in the global economy? Wars have been started for less.
Whilst the chance of an economic attack on the US by China as described above might be considered fantasy, the fact remains that the US has put itself in a position where it is theoretically possible that such a strategy could be carried out and where the very hint of a threat by the Chinese could be extremely damaging. Sino-US relations have never been particularly friendly and the two countries have traditionally been seen as opponents, if not enemies. Maybe the struggle between communism and capitalism hasn’t completely disappeared after all and the Chinese have been merely biding their time.
The US has been quite vocal about the way it thinks China should manage its currency but it is not really in a position to dish out advice on a subject in which it is clearly not an expert. The current Bush administration continues to officially support a strong dollar policy but the reality is somewhat different – and they are kidding no-one. Either the US has no control over its own currency or the huge depreciation in the value of the dollar was what they wanted all along. However, today the US has clearly lost a large degree of control over its currency, and by association its economy, because it has put itself in the position of debtor to China (and to other countries) and this makes the US a riskier place to invest than is widely perceived, regardless of its current credit rating. A rapid sale of US treasuries by China might seem like a black swan event but it is one that is theoretically possible and which can be foreseen. If it ever occurs then you don’t want to be holding US dollars. Even without any action on the part of foreign holders of US Treasuries, the balance of power has certainly changed and the US has placed itself in a vulnerable position.”
