The ongoing spat between the US and China over the rate of yuan appreciation has boiled over into something more interesting.

Last night Chinese officials threatened the possibility of selling down their US treasury holdings and thereby consigning the US$ to the trashcan. The Chinese are experts at promoting the maxim “don’t throw stones in glasshouses”. They are very astute at pointing out inconsistencies in arguments no doubt employing age old Confucian wisdom.

How the relationship between China and the US will pan out is anyone’s guess but we can be clear about one thing and that is the balance of power has shifted ever so slightly. The phenomenal success of the Chinese economy, based mostly on a large manufacturing base, has given the Chinese are strong foothold in global affairs. Whereas once it was a sleeping dragon content to rule its own domain now it is a major player.

At the same time it has built a strong domestic economy and plays host to the Olympics next year. It seems the US may need China more than China needs the US.

The situation doesn’t look too good for the US. Collapsing credit markets need a steady government security base to hold it all together. Any sell of in the US Treasury market would be a real disaster sending stocks down as well as the dollar.

To some extent we’ve been through this before with the Japanese. In the mid 90s Fred Bergsten hit the headlines calling for a stronger yen. This caused the $ to fall to a record low of 79.65. He was still making this call back in 2002 when he outlined strong reasons for abandoning the Clinton “strong dollar” policy.

This delicate game was fictionalised by Tom Clancy in his book “Debt of Honour” which told of a plot to destabilise the US economy by crashing the Treasury markets and the $. Of course the US won in the end but in real life who knows what would happen. The US authorities run some major interference in the markets when required and i am sure that any severe destabilisation of financial markets would see national security considerations apply (well if they haven’t got that sorted they should!). Sadly many of Clancys’ novels end up happening in real life.

The Chinese are very tactical and astute in their political strategy and very protective of their sovereignty. It will be interesting to see how this plays out but more weakening of global markets cannot be ruled out and with the end of the credit fuelled asset price boom added into the mix cash will be king.
