I have been on a crash course to try and understand the arcane details of what options are available if the current debt ceiling is reached with no action taken to raise it and the balance in the government’s account actually becomes zero. I thought I would share what I have learned so far.
We tend to think of the US government as having a checking account, just like many of us, and of the debt ceiling like a loan given to us by a bank. This is mostly true, except in one significant way that I will get to below. This informative article by John Carney says that the government does have something that looks like a checking account in which all the money it receives continuously (tax receipts, air transport security fees, the postal service, Medicare premiums, etc.) is deposited and from which all its payments (federal employee salaries, income tax refunds, NASA, interest on our debt, unemployment insurance benefits and paying defense contracts) goes out. To get an idea of the scale of transactions in that account, at the beginning of last Friday, the account had $83 billion and during the day it received $7 billion in deposits and paid out $13 billion in withdrawals, leaving it at the end of the day with $77 billion.
