It was about a month ago. My immigration attorney was talking about it, but i wasn't paying close attention because I was just trying to find out why my permanent residency is taking so long.
I have not checked it out personally, but I do have a Ban Reservas account I seldom use. If it is 5% in dollars that is good (if you think it is safe). I got that rate for a few years in Puerto Rico (but those banks were FDIC insured - even though one of them failed after i got my money out)
I did check on the BanReservas web site but they don't post the CD rate but you could call or e-mail them
