Not raising the debt limit does not translate into defaulting in debt. Old debt can be rolled into into new debt. That does not affect the debt ceiling.
However, we couldn't make govt payroll, medicare payments and so forth.

Except of course for domestic reasons that US would default on its debts long before foregoing all those other things.
If we don't raise the debt ceiling I guarantee you we will default on our debt. Guar-an-tee.
