Last week, the NY Fed released their latest FX volume data which goes back to October.
My friend Rhonda Staskow has compiled some great charts illustrating the breakdown of foreign exchange trading in the US, UK, Australia, Canada and Singapore.
Bottom line is that volume continues to rise in the spot market as currencies become a bigger story. The EUR/USD and USD/JPY are 2 most actively dealt currency pairs in NY trading. The following charts are for NY trading but here is her full powerpoint presentation.
