Debt limit
A debt limit is a legislative mechanism restricting the total amount that a country can borrow or how much debt it can be permitted to take on. Usually this is measured as percentage of GDP. A handful of countries have debt limitation laws in place. Among the more famous cases is the United States debt ceiling but there are several other countries that have debt limits.[1][2]
Poland is the only nation with a constitutional limit on public debt, set at 60%. By law, a budget cannot pass with a breach in place.[3]
