This morning, the U.S. Labor Department released the latest Consumer Price Index. That indicator of inflation was up only slightly. More on that. And banks have about nine months until they’ll have to comply with what’s called The Volcker Rule. That’s the part of Dodd-Frank that’s named after Paul Volcker, the former Federal Reserve chairman. The Volcker Rule says banks cannot own hedge funds or invest for their own benefit. They’ll have to stick  to helping their customers make money. Simple as it may sound, the Volcker Rule is incredibly complex. But banks have a new tool to help them implement it.
