On Friday October 16, CME Group (NYSE: CME) decided that it wants to allow customers across the globe to use gold, physical gold, as collateral on all of its exchange products (alternative investment products, futures and options, etc). The member notice was sent out on late Friday, giving instruction on how the use of gold would work. Firms are allowed to post gold as collateral up to $200 million, the collateral will cover performance bond (margin) requirements.

At first we thought that it was rather unusual that the US Treasury Secretary, Geithner, would make a special trip to China. What were the reasons for his trip? The purpose of the mission became clear when Geithner announced that the dollar would remain as the world reserve currency. There had been a lot of scuttle but about replacing the dollar as the world reserve currency, but some of this has been put to rest with the support of Chinese backing.

As usual the Chinese remarks were guarded and a bit fuzzy. Guo Shuging, Chairman of China Construction Bank and former head of the country's foreign exchange administrator said: "In the short term, I don't think we can find another currency to replace the US dollar." He also said, "the US dollar is the main currency because their economy is number one in terms of competitiveness, in terms of innovation."
