A budget crisis is an informal name for a situation in which the legislative and the executive in a presidential system deadlock and are unable to pass a budget. In presidential systems, the legislature has the power to pass a budget, but the executive often has a veto in which there are insufficient votes in the legislature to override. If no emergency provisions are made for the government's budget, a budget crisis may develop into a government shutdown in which the government temporarily suspends non-essential services until a budget is passed.
