You're misunderstanding the basics of banking like the other fellow I responded to. I provided a link by the IMF that explains the fundamentals in another reply. I'll provide another one: https://www.investopedia.com/terms/f/fractionalreservebanking.asp

Normal commercial banks cannot just print money, which is exactly what you're implying with "phantom money." The money has to come from somewhere and/or be backed by something. So no, a bank can't just magically turn $1000 into $10,000 without something securing the additional money or the extra money coming from other funds. Only the Fed (or other countries' central banks/governments) can print money on a whim.
