debt limit

The debt limit (or debt ceiling as it is sometimes called) is a self-imposed cap on the amount of borrowing the United States government can make from other entities (the people, foreign governments, etc). Since the limit is self-imposed, it can also be arbitrarily raised or lowered on the vote of Congress.
