CBO finds that:

* The current economic situation is quite fragile, largely as a result of the difficulties in mortgage markets and other financial markets. Much of that fragility arises from falling house prices, which affect consumers through their housing wealth and lenders through their loss of collateral. It is exacerbated by the growing complexity of financial instruments and entities, which may make it difficult for participants to know what risks they are assuming, and by the leverage of both borrowers and financial market intermediaries, which means that it is difficult to prevent liquidity and solvency problems from spreading throughout the financial markets.
* Foreclosures are an expensive way to resolve delinquencies. A large number of foreclosures is also likely to reduce the demand for houses, as potential purchasers conclude it would be better to wait until prices stop falling. Thus, excessive foreclosures could trigger a downward spiral of house prices that could take them below what would be justified on the basis of normal relationships to income and production costs. Such a downward spiral would exacerbate the problems in the financial markets, and by reducing household wealth, could reduce consumption spending, increasing the likelihood and severity of a recession. While actions could be taken to limit the risk of such a downward spiral in housing prices, it is not feasible for policy interventions to stabilize house prices at current levels since such prices are strongly influenced by the significant inventory of unoccupied houses for sale.
* Significant impediments stand in the way of private market resolution of the difficulties in the mortgage market. In order for large numbers of mortgages to be restructured, procedures must be developed to secure the agreement of the institutions that hold second mortgages. Because most mortgages are securitized, resolution procedures also have to respect the limits of securitizing agreements. Without committing resources, the Congress could provide a standard for mortgage restructuring that might assist agreement among the first- and second-lien holders and simplify the decisions lenders have to make. Legislation could also change the treatment of mortgages in bankruptcy, which would help borrowers and might increase the pressure on lenders to voluntarily restructure loans outside of bankruptcy; such a change, however, might also lead to higher interest rates on future mortgages.
* Direct federal provision or guaranteeing of credit to mortgage markets could help avoid foreclosures and ease the downward pressure on house prices, helping the market to adjust in an orderly manner. It would also shift part of the cost of mortgage losses from current lenders and investors to taxpayers. Most of the proposals under discussion involve modest federal subsidies and would probably affect several hundred thousand homeowners.
