[Updated: All ETCs resumed trading on Monday afternoon.]

All of the AIG-backed exchange-traded commodity (ETC) products offered in Europe by ETF Securities have reopened for trading, according to the company.

AIG is the credit counterparty for 113 of the company's 131 ETCs. Trading in those AIG-backed products was formally halted by the London Stock Exchange on September 17, as concerns mounted about the future of AIG. But with the U.S. government stepping in to backstop AIG, those concerns have disappeared, and trading in the products is returning to normal. (One could even argue that, with the U.S. government clearly saying that AIG is "too big to fail," the credit strength of ETF Securities is strong indeed.)

Sixty-six of the ETCs resumed trading on Friday, September 19, and all 113 ETCs were trading by Monday afternoon.

ETF Securities also offers 18 ETCs that are either backed by Shell Oil or supported by physical holdings of precious metals bullion; these shares were not impacted by the trading halt, and were not in any way impacted by AIG's troubles.
