Yes I think that’s right. No

Yes I think that's right. No single bank can lend more than it has or can get quickly but the whole banking system can create new "money" but central to this system is the State bank which is the ultimate source in the system that can create new money (claims on wealth) "out of thin air" (and cause too much inflation if it gets it wrong, it being official policy in Britain, the US, etc to inflate the currency by about 2 percent a year). Not the same as creating more wealth of course. Only humans applying their mental and physical energies to materials that originally came from nature can do that.
