Actually, the GP's explanation is closer to true than yours is. I was taught the same explanation you gave, but it doesn't fit the facts on the ground. Banks do

Actually, the GP's explanation is closer to true than yours is. I was taught the same explanation you gave, but it doesn't fit the facts on the ground. Banks don't base the loans they issue on deposits (the closest to this they come are the capital requirements regulators impose on them), they base them on models of the borrower's ability to repay and on models of the ability to resell the loan (aka 'securitization', though less so since that practice helped drive the financial crisis). If the models fit, the loan amount is credited to the seller, and debited to the buyer, essentially creating money 'out of thin air.' The economist Steve Keen is perhaps one of the more vocal advocates of this view (http://www.debtdeflation.com/blogs/ http://www.debtdeflation.com/blogs/).
