Many federal agencies need appropriations enacted into law to incur obligations and spend money. When required appropriations expire without replacement, affected activities can face a funding lapse.
A government shutdown is fundamentally an appropriations problem.
Agencies follow shutdown plans. Some activities continue because they are funded differently or legally excepted, while other operations pause and employees may be furloughed.
A shutdown does not mean every part of the federal government stops operating.
The statutory debt limit constrains Treasury borrowing. It does not itself authorize new spending programs; spending and tax laws create the obligations that Treasury must finance.
Raising the debt limit does not, by itself, enact a new spending program.
When borrowing reaches the debt limit, Treasury can use authorized accounting measures to preserve borrowing capacity temporarily. Those measures are finite.
Extraordinary measures delay the constraint; they do not permanently resolve it.
