Humour me. I save 1k per month. I work for a business that makes stuff. They sell it. They pay me. I save a portion of that. How does that 1k of savings equate to debt elsewhere?Let's assume that you're saving that money in the bank. Your savings is a liability of the bank. Someone else's loan (car loan, home loan, credit card, sba....) is the bank's asset. Finance 101.
So let's say you work for a homebuilder and someone takes out a loan for $100,000 to build a home. When the loan is originated, two things happen: first, the bank records the loan against the individual and whatever collateral they post. Second, the bank deposits the amount of the loan in the borrower's account (escrow, etc). The borrower pays the homebuilder and the homebuilder then pays you in turn. Your savings are essentially a call on that home loan. Let's say that the person who borrowed the money is a baker and you frequent their bakery to the tune of $10/day. Every month or so your patronage of their business allows them to retire ~$300 of that home loan in this simple mini economy we've built.
Translating things to the real world, your $1,000 in savings isn't just a call on that one home loan, it's a call on any loan, to anyone, of any maturity, at any time. Your savings could be a call on a part of a loan to an automaker due in eight years, or a cellular service provider due in twenty years. Your savings, when you spend them, can be used by the debtor to pay off part of their debt or go buy factors of production at which point that seller can redeem any part of that debt.... so on and so forth.
While theoretically you can redeem your savings in the form of high powered money (actual physical cash) this is hardly ever done so most "money" just exists as a ledger entry.
Now let's say a bunch of private sector workers such as yourself desire to build up cash savings. The only way this is possible is if a non-personal entity, such as a business or a government, borrows and then spends money into the economy at which point the money can be accumulated by those who desire to hold it. If you were sharp, you caught an important point there: banks don't lend money to governments the same way that they issue a loan to you or me. What happens instead is that the government borrows money from private individuals (usually through an intermediary) and that loan is considered to be of such high quality that it can be posted as collateral for an additional loan (indeed, USTs are the collateral bedrock of the global financial system). As a result, government borrowing increases private savings through a two part process: the borrow and spend (which creates no new money on net) and the second-order effect whereby the government bonds become collateral for private sector loans (which does create additional money).
There's another mechanism by which government spending can inject new money but it's not important for the sake of this conversation... but I will say this: Bernanke was seemingly aware of it whereas Trichet, Draghi, Kuroda, etc were/are not.
