New Rule Hits in July — The Smart Money Already Moved (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.
