The amount the bank is legally allowed to create depends on how much people have deposited into their accounts. So if you put say $100 into your checking account the bank may be able to lend several times that. It is effectively the same as lending out what has been deposited, except magnified.
The point remains however that it may be best to find a bank that has a relatively ethical outlook to lending. 
Hi Venerable,
Thank you for replying. So would you say the passage I quoted is addressed to a monastic’s livelihood rather than a layperson’s? Not to say a layperson should engage in deception as their livelihood, but that the passage is primarily meant for monastics. And as laypeople, we can use this teaching as a guide but shouldn’t extrapolate it as also directly applying to us.
Oh, yes, definitely. It’s always used in a monastic context. Wrong livelihood for lay people is the standard list of five—trade in weapons and so on.
As you say, it shows some principles useful for everyone, but it’s explicitly about monastic livelihood.
