It is good known that the US fiscal crisis caused by sub-prime mortgage crisis in 2007 has developed a planetary economic crisis. Harmonizing to the information of Cutler, Slater and Comlay ( 2009 ) , more than $ 1A trillion assets were lost in big U.S. and European Bankss between January 2007 and September 2009. Brunnermeier ( 2009 ) point out that “ an addition in mortgage delinquencies due to a countrywide diminution in lodging monetary values was the trigger for a matured liquidness crisis that emerged in 2007 ”
1.1 The definition of sub-prime mortgage
In US, loan is really popular and people can acquire the house, auto, even telephone measure in this manner. Harmonizing to Fair Isaac Corporation ( FICO ) ( 2006 ) , the recognition mark was ranged between 300 and 850. The more recognition mark, the less hazard of loan. Besides, Pogol ( 2008 ) claimed that if recognition mark of the mortgage was below 600, it would be listed as the sub-prime mortgage. Finally, Okah and Orr ( 2010 ) defined the sub-prime mortgage as a loan made to borrowers with a hapless recognition history, or those who did non run into the graduated table for obtaining a premier mortgage loan.
1.2 Main beginnings of the fiscal crisis
There were three chief beginnings for the current crisis. First, harmonizing to Amarasinghe ( 2010 ) indicated there was an extra capital globally in the early 2000 ‘s due to Asiatic economic systems who had invested in “ Western exchequers to protect themselves following the late 1990 ‘s recession ” . In order to increase the value of capital, the investing directors decided to put US mortgage market because of the guaranteed return. Second, due to the dot.com bubble and September 11th, the involvement rate was lowered to merely 1 % by the Federal Reserve Chairman Alan Greenspan in order to excite the economic system growing. ( Recession Ready, 2010 ) Finally, based on such a inexpensive recognition, there was a bad lodging bubble. More people needed to purchase a house and the rise in the demand will do a rise in monetary value of house. The addition in monetary value will pull investors who would look to purchase many houses as an investing. They can gain more by selling them in the hereafter. This will farther created more demand and further increased the monetary value. As a consequence, more and more speculators will take to acquire houses by loan. ( Stock-Market-Investors, 2008 )
1.3 The model of essay
To get down with, a big portion of subprime mortgages securities in the mortgage market will be displayed by a chart. Then, presenting the advantages and disadvantages of the mortgage securitization, securitization is likely the important ground of the current crisis. Furthermore, two typical subprime securities shows that the transitive procedure of hazard. Finally, there are some groundss to demo the inaccurate recognition evaluation in the crisis.
The Role of High-risk Sub-prime Mortgage Securities
Sub-prime Mortgage Securities have a important portion in the mortgage market. Harmonizing to Perry ( 2008 ) , a clear chart above ( chart 1 ) demonstrated the subprime portion of mortgage inceptions from 2001 to 2007. It is obvious that around 20 % is subprime portion of mortgage inceptions between 2004 and 2006, about three times larger than the 7-8 % portion from 2001 to 2003. At the terminal of 4th one-fourth 2007, the subprime portion fell to merely 3.1 % , lower even than the 7-8 % between 2001 and 2003. He besides claimed that the subprime crisis is resulted from the 20 % subprime mortgage portion from 2004 to 2006. Obviously, it is likely that the big portion of sub-prime mortgages had played a important function in this crisis.

Subprime Mortgage Securitization
Darting mortgage market was chiefly raised by the fiscal invention, particularly mortgages securitization. Traditionally, Bankss lent to persons by a loan, where hard currency payments were made to the initial loaner until adulthood. But these loans are non tradable. However, in recent old ages, Bankss could sell the mortgages to the bond markets by securitization. Gurusamy ( 2009 ) defined securitization as the procedure whereby assets-claims to a watercourse of future hard currency flows such as a refund of loans, bonds, and mortgages are bundled up into big pools and sold as securities.
Securitization provides many benefits for fiscal establishments and investors. First, Cowan ( 2003 ) illustrated that it provided the liquidness of mortgage and decreased the adoption cost of the fiscal establishments. Financial establishments could turn around the full value of their loans instantly and re-start a new loan by utilizing that capital. It can raise new finance in the capital market more expeditiously. Second, Cox, Faucette and Lickstein ( 2010 ) claimed that the advantage to investors was cut downing the hazard of mortgage securities by variegation. “ By pooling the assets together, the hazard of each plus defaulting is offset by the other assets in the pool. ” Finally, they besides explained the securitization could assist investors to take more types of hazard securities harmonizing to their hazard penchant. For illustration, Risk-loving investors such as hedge financess or investing bank invested in securities with a lower evaluation because they prefer a high default hazard would convey them a high return.
Although securitization brings to many benefits, there are still some jobs on it. First, harmonizing to Stock-Market-Investors ( 2008 ) , the deficiency of lucidity and transparence in the mortgage securitization shows that it is difficult for the investors to cognize which houses are included in the pool. Besides, Cohan ( 2007 ) claimed that the packages of mortgages are so complex that their monetary value is difficult to be calculated. Finally, the variegation could non countervail the systematic hazard of mortgage securities. However, “ such a systematic hazard was besides non priced into the subprime mortgage pools. ” Stock-Market-Investors ( 2008 )
2.2 Two Significant Mortgage Securities in the Crisis
Kirk ( 2009 ) claimed that loaners or conceivers frequently securitize mortgages into bonds sold to investors. There are two typical mortgage bonds that have played of import functions in the current crisis.
2.21 Mortgage Backed Securities ( MBS )
One type of mortgage security is mortgage-backed securities ( MBS ) . Rosen ( 2007 ) defined MBS as a bond that was changed from mortgages by securitization and its return was the payment of a aggregation of single mortgage in the mortgage market.
Cowan ( 2003 ) demonstrated the procedure of securitization. First, that was called a particular intent vehicle ( SPV ) must be generated by a company. The SPV is lawfully separate from the company, or the holder of the assets. Typically the MBS begins when the issuer purchased a aggregation of mortgages from the conceivers. As payments were made on the mortgages, they were passed through the SPV to bondholders. He besides claimed that
Cox, Faucette and Lickstein ( 2010 ) thought that the investors could purchase the MBS harmonizing to their hazard profile. The purchase of MBS non merely kept the value of their capital rise, but besides helped fund place mortgages including sub-prime mortgages. Kirk ( 2009 ) claimed that subprime mortgages securitized into MBSs are sliced up into different hazard categories or tranches of bonds. Rating bureaus awarded each tranche a recognition evaluation. MBS bonds have different precedence claims on the involvement and principal. Senior bond tranches are paid before lower tranches. If there is non sufficient hard currency flow, the lower tranches may non be paid. As lower tranches have the higher hazard without being paid, they were given higher returns than the senior tranches.
Since MBSs by securitization brought more benefits to fiscal investors, the demand in MBSs has been increasing. Based on Stock-Market-Investors ( 2008 ) , in order to fulfill the demand, Bankss began to take down the mortgage making guidelines and much more mortgages were offered to higher-risk borrowers such as sub-primers. To get down with, the mortgage agent supplied “ the declared income, verified assets ( SIVA ) loans, ” which means the borrowers need to province it and demo that they had money in the bank if they need the loan. Then, the agent provided “ the no income, verified assets ( NIVA ) loans ” , which means borrowers merely needed to demo cogent evidence of money in their bank history without a cogent evidence of employment. Finally, making guidelines kept acquiring looser and created NINA which is No Income No Assets.
Collateralized Debt Obligation ( CDO )
The other type security is collateralized debt duties ( CDOs ) which were repackaged from lower degree tranches of MBSs by investing Bankss. ( Kirk 2009 )

Another chart above ( chart 2 ) illustrated the CDOs which besides created tranches for their bonds harmonizing different hazard categories. Brunnermeier, ( 2009 ) claimed that they were senior with low involvement rate, first balcony with average involvement rate, and junior with high involvement rate. Each tranche attracted different investors and has a different precedence claims on the involvement. The senior tranche is for low-risk investors such as insurance houses, but it is first to be paid off. In contrast, the junior tranche is for the extremely leveraged investor such as hedge fund and paid at last. The first balcony tranche is for medium-risk investors and is between these extremes. Kirk ( 2009 ) besides points out that senior CDO tranches have been awarded the highest recognition evaluation AAA although MBS bonds rated below investing class were contained in these CDOs.
2.3 Inaccurate recognition evaluations
In the subprime crisis, recognition evaluation bureaus played a cardinal function on the appraisals of sub-prime mortgage securities such as mortgage-backed securities and collateralized debt duties. Stolt ( 2008 ) defined that “ Credit Rating Agencies ‘ chief map is to mensurate the ability of an entity – this can be a individual, a corporation, a security or even a state – to run into its duty ” For illustration, there are three big recognition evaluation bureaus named as Moody ‘s, Standard and Poor ‘s, and Fitch in US.
There are some groundss that the evaluation bureaus made some important errors. First, Securities ‘ recognition evaluations provided a downward colored position of their existent default hazards, because they were based on the recognition evaluations bureaus ‘ native extrapolation of the favorable economic conditions, such as the premise that house monetary values would ne’er fall, and the failure to recognize the inducement to default in this instance. Second, they were used to measuring individual company default hazard and had no experience at systemic hazard. But AAA is a step of default hazard and says nil about correlativities. Besides, the evaluation bureaus suffered from struggles of involvement, as they were paid by investing Bankss and other houses that creat and sell these securities to investors.
