We've looked at {the possibility of debt ceiling constraints} and thought about making preparations and so on. The arithmetic is very simple. The revenue that we get in from taxes is both irregular and much less than the current rate of spending. That's what it means to have a deficit.
So immediately, there would have to be something on the order of a 40 percent cut in outgo. The assumption is that as long as possible the Treasury would want to try to make payments on the principal and interest of the government debt because failure to do that would certainly throw the financial system into enormous disarray and have major impacts on the global economy.
So this is a matter of arithmetic. Fairly soon after that date, there would have to be significant cuts in Social Security, Medicare, military pay or some combination of those in order to avoid borrowing more money. If in fact we ended up defaulting on the debt, or even if we didn't, I think, you know, it's possible that simply defaulting on our obligations to our citizens might be enough to create a downgrade in credit ratings and higher interest rates for us, which would be counterproductive, of course, since it makes the deficit worse.
But clearly, if we went so far as to default on the debt, it would be a major crisis because the Treasury security is viewed as the safest and most liquid security in the world. It's the foundation for most of our financial -- for much of our financial system. And the notion that it would become suddenly unreliable and illiquid would throw shock waves through the entire global financial system.
