US banks await Volcker Rules decision
10 December 2013 Last updated at 10:08 GMT
Some of America's top financial regulators decide on Tuesday whether or not to introduce a set of controversial rules regarding how US banks make money.
The Volcker Rules would prevent banks from trading for their own gain rather than that of their clients, while also limiting their ability to invest in hedge and private equity funds.
The regulations are designed to prevent the kind of high-risk deals that led to the financial collapse of 2008.
