Yes, if you define bank loans
Yes, if you define bank loans as money then in making a loan a bank is ceating money (by definition). If they extra loans over and above those being repaid then they expand the "money supply" (by definition). But the question remains: where does the money to make the loans, and the extra loans, come from? Is it simply conjured up out of thin air or is it money that the banks have borrowed from depositors, other banks and financial institutions, and/or the central bank? I don't think Zeitgeist is a reliable source of information on how banks work. Maybe they have learnt something in the meantime, but at the beginning they were out-and-out thin-airists.
