I'm living in a community where gold is the currency of choice, and I convince a bunch of people in my community to deposit gold pieces with me. I have a huge pile of gold. Whenever somebody asks me to give them back their gold, I reach into the pile and hand them pieces equal to the amount they deposited, but not necessarily the same pieces. But this happens infrequently enough that most of the time, the pile just sits there. So I decide to only keep half the pile sitting there -- more than enough to cover the rate at which my customers make withdrawals -- and loan out the rest to borrowers I deem credible. I charge interest to make up for the losses I take on bad borrowers and actually make enough profit on this interest to keep some and pay some out to account-holders. I would say I am 1. conducting fractional reserve banking, with a 50% reserve ratio, and 2. not creating a new currency (everybody still transacts in gold pieces). Are you saying that this is NOT fractional reserve banking, or that it IS creating a new currency?
