|The US trade balance (goods+services, per month, seasonally adjusted)|
Warning for Indian readers: In India, the term `trade balance' pertains only to merchandise trade. In the US, the monthly trade data covers both goods and services. So it is a meaningful measure of what is going on in international trade, unlike the corresponding Indian data.
Bretton Woods II first broke down in the financial crisis. In the downturn, the mighty American consumer purchased fewer 50" television sets. The US trade deficit dropped nicely all the way to $25 billion per month. Alongside a rise in the US savings rate, this looked like a world which was rebalancing.
In recent months, this movement reversed itself and the US trade deficit once again started getting worse. A deterioration of $20 billion per month is visible; i.e. a deterioration of $240 billion a year. Suddenly, the story of global imbalances righting themselves came under question. The present US run rate is around $40 billion a month or $0.5 trillion a year.
Alongside this, we have news that the Chinese reserves rose by $194 billion in Q3 2010. The Chinese seem to have also passed on some of their problems of exchange rate pegging upon their neighbours by purchasing Japanese, South Korean and Indonesian assets. I am not aware of such behaviour having been observed prior to this in human history. Japan, South Korea and Indonesia have taken unkindly to this behaviour. Given the opacity of the Chinese regime, one can't help wonder if similar things are going on through less visible channels - e.g. a Chinese sovereign wealth fund buys $10 billion of OTC derivatives on Nifty.
So we seem to be headed for quite some escalation of conflict over the Chinese exchange rate regime. Here are some interesting readings on the subject:
