The 2006 Puerto Rico budget crisis was a political, economic, and social crisis that saw much of the government of Puerto Rico shut down after it ran out of funds near the end of the 2005–2006 fiscal year. The shut down lasted for two weeks from 1 May 2006 through 14 May 2006, leaving nearly 100,000 public employees without pay and closing more than 1,500 public schools.
The crisis was publicly criticized by the business sector, non-profit organizations, Puerto Rican celebrities, and the general public (by means of opinion polls), and was described as the consequence of a political power struggle between the Commonwealth's main opposing political parties: the Popular Democratic Party and the New Progressive Party.
In April 2006, Governor Anibal Acevedo Vilá (PPD) announced that the central government of Puerto Rico did not have enough cash flows to pay projected operating expenses for the months of May and June, including the salaries of thousands of public employees. The governor asked the Legislative Assembly of Puerto Rico to approve an emergency loan of over $500 million US$ so that the government could keep running, which the government would repay using 1% of a newly proposed sales tax, or else the Governor would order a partial shutdown of central government operations, including the closing of numerous agencies.
The Puerto Rico Government Development Bank offered to supply the loan, but insisted on a tax reform plan that requires this new tax to be collected with a predetermined rate or amount be set aside exclusively for the loan repayment. The NPP-majority Senate approved the loan based on the proposed tax rate, but the NPP-majority House of Representatives refused to do so.
In a televised address on 27 April, Governor Acevedo Vilá announced that most of the government agencies would be shut down beginning 1 May, and would remain closed unless the House approved the economic plan. Government activities relating to health and security (including hospitals and police stations) would remain open, although medical professionals questioned whether hospitals would function if staff went unpaid and also raised the issue of government-funded prescriptions, whilst private security firms on contract to the government said they might cease work if the government did not pay what it owes them.
