Sometime between this date and Oct. 31, according to the Congressional Budget Office, the government would run out of cash. It would have to slash spending 32 percent over the next month, according to the Bipartisan Policy Center. Treasury would probably make its top priority the payment of interest and principal on its debt to avoid a default. Either way, some programs wouldn't be funded, possibly including Social Security, veterans' benefits and Medicare.
OCT. 23:
A $12 billion Social Security payment is due. Without an increase in the debt limit, Treasury might have to wait two days to accumulate enough cash to make that payment, according to the Bipartisan Policy Center. Missing the payment would likely intensify fears that the government will soon default.
OCT. 24:
The government must redeem $93 billion in short-term debt. It will likely raise the cash to do so at its Oct. 21 auction. But it's possible that Treasury would run short of cash or some error might occur, resulting in default.
OCT. 31:
The Treasury must pay $6 billion in interest on the debt. If it doesn't have enough cash, it would default. If the debt limit hasn't been raised by this point, much higher rates and far less government spending would likely nudge the economy toward recession.
NOV. 1:
The government faces a stack of bills: $25 billion in Social Security benefits, $18 billion in Medicare reimbursements, $12 billion in military pay and veterans' benefits and $3 billion for other benefit programs. With no increase in the debt limit, these payments would likely be delayed at least two weeks, the Bipartisan Policy Center estimates, to give the government time to build up cash.
NOV. 15:
The Treasury must make an additional $29 billion in interest payments. If the economy has slowed and tax payments fall short of expectations, the government might not have enough cash and would have to default.
