Debt ceiling — what it is and what it isn't
The debt ceiling is a statutory cap on total federal debt. When the cap is reached, Treasury cannot issue new debt to cover already-authorized obligations — including bond payments, Social Security checks, military pay, etc. Raising the debt ceiling does NOT authorize new spending; it authorizes the Treasury to BORROW MONEY TO PAY FOR SPENDING CONGRESS HAS ALREADY APPROVED.

What the debt ceiling does
Caps the total amount Treasury can owe in outstanding debt. When debt approaches the cap, Treasury must use "extraordinary measures" to keep paying obligations until Congress raises the cap.

What it does NOT do
It does NOT authorize spending. Spending is authorized by appropriations and entitlement laws Congress already passed. The debt ceiling is about whether Treasury can borrow to pay those bills.

What "default" means
If the ceiling is reached and Treasury exhausts extraordinary measures, the U.S. defaults — fails to pay obligations on time. This has never happened. The market consequences would be severe: U.S. debt is a global benchmark; a default would reprice trillions of dollars in assets.

How to read debt-ceiling votes
A "no" vote on raising the debt ceiling is a vote AGAINST paying for spending Congress already authorized. It's NOT a vote against new spending. Both parties have used this distinction to message the same vote in opposite directions.
