When someone borrows money from a bank does someone else's account go down? No. So where does the money come from?
All increases in purchasing power are reversed. Either
1: The loan is paid back. Everybody back to square.
2: The borrower goes bust. The bank loses.
3: The currency is devalued. Savers lose.
As nobody has any intention of reducing debt or going broke. That leaves 3.
This isn't actually how it works
I'm trying to say this using no economic terms at all, so others with economic experience out there bear with me
Banks are magicians who create money out of thin air - to a limit controlled by the central bank (in Australia the Reserve Bank).
When banks lend money they lend amounts from their 'vaults' - the collective savings of everyone who has money with the bank, retained profits and amounts they borrow from the money market at lower rates.
They are legally required to keep a small amount of cash available on hand to cover withdrawals from savings accounts - This % is set by the central bank. Of course banks also manage their cash reserves for operational & other costs.
They are then repaid that loan amount plus interest. The INTEREST is actually an increase in the money supply, though not the paper money supply, purely the electronic supply. Remember that the interest is paid over many years so has only a very slight effect on the money supply or currency valuations.
If borrowers go bust banks take the assets over which the loan was secured & sell it. They don't always get all their money back, but often have insurance (such as LMI) or other mechanisms available to claim back their money. Rarely, banks end up in positions where they cannot get all the money back & lose out, but this is severely outweighted by the number of situations where they can recover the cash.
Currencies have demonstrated a tendency to devalue over time (called inflation) due to many factors other than bank lending. Bank lending is a responsible means of allowing people to lay-by big purchases, paying for the cost of borrowing the money.
To go into more depth I really have to begin using economic terminology, so I'll stop with the point that banks do lend the money from the savings deposited in their bank & legislated bank lendings is largely not a major inflationary cause for economies.
