A new rule goes live in July — and the banks are quietly crushing it (Ad)

A little-known regulation quietly goes into effect this July. And it's already being exploited by Wall Street and the Big Banks… It gives them the green light to treat a certain tangible asset as equivalent to cold, hard cash. Not stocks. Not real estate.
