fuse lit on jpms $trillion interest rate swaps, page-26

why spend $1560 an ounce to make $156 buying the physical when you can post collateral of $176 and make the same amount on a futures contract?
---------------------
The answer to that question is because you cannot get in over your head. If the POG crashes it may leave a nasty taste in your mouth whereas those that are highly leveraged hoping to MAKE the same amount with less outlay can leave a nasty taste in many mouths as they often use others money to LOSE the same amount.
