You've got that all mixed up. Loans create deposits. That's how money grows. Presumably the loan is to buy something, and the deficit spending is to buy something. Buying is the source of price pressure.
Money begins with the loan.
That is straight pkt. Loans create deposits. Banks make loans on demand at the margin unless they are capital constrained. There you go again. Changing interest rates may accomplish that, but you can't count on it.
