The question is whether national government deficits can exceed nongovernment savings in the domestic currency (domestic plus rest-of-world savings). From our analysis above, we see that this is not possible. First, a government deficit by accounting identity equals the nongovernment’s surplus (or savings). Second, government spending in the domestic currency results in an equal credit to a bank account. Taxes then lead to bank account debits, so that the government deficit exactly equals net credits to bank accounts.
