loans not in residential mortgages or mortgage-related securities and set down standards preventing concentrations of loans to single borrowers. It required them to completely divest themselves of junk bonds by July 1, 1994, meanwhile segregating junk bond holdings and direct investments in separately capitalized subsidiaries. Consequences Savings and Loan were not the only financial institutions that were adversely affected by the crisis. Many banks failed as well. Between 1980 and 1994 more than 1,600 banks insured by the FDIC were closed or received FDIC financial assistance. From 1986 to 1995, the number of federally insured savings and loans in the United States declined from 3,234 to 1,645. This was primarily, but not exclusively, due to unsound real estate lending. The market share of S&Ls for single family mortgage loans went from 53% in 1975 to 30% in 1990. U.S. General Accounting Office estimated cost of the crisis to around $160.1 billion, about $124.6 billion of which was directly paid for by the U.S. government from 1986 to 1996. That figure does not include thrift insurance funds used before 1986 or after 1996. It also does not include state run thrift insurance funds or state bailouts. The federal government ultimately appropriated $105 billion to resolve the crisis. After banks repaid loans through various procedures, there was an estimated net loss to taxpayers of somewhere between ($123.8–132.1) 124 and 132 billion dollars by the end of 1999. The concomitant slowdown in the finance industry and the real estate market may have been a contributing cause of the 1990–1991 economic recession. Between 1986 and 1991, the number of new homes constructed dropped from 1.8 million to 1 million, the lowest rate since World War II. Some commentators believe that a taxpayer-funded government bailout related to mortgages during the savings and loan crisis may have created a moral hazard and acted as encouragement to lenders to make similar higher risk loans during the 2007 subprime mortgage financial crisis.
