What is a term used for emergency bank closures mandated by Congress to relieve financial crises?

A term used for emergency bank closures mandated by Congress to relieve financial crises is "bank holiday." This measure allows banks to temporarily close their doors to prevent runs on banks and stabilize the financial system during times of economic distress. The most notable instance in the United States occurred in 1933 during the Great Depression, when President Franklin D. Roosevelt declared a nationwide bank holiday.
