Mortgage Backed Security

from Wikipedia, the free encyclopedia

A mortgage-backed security ( English mortgage-backed security , abbreviated as MBS ) is a bond , their cash flows through the interest - and repayments a pool of mortgage be worn secured claims. It is therefore a special case of an asset-backed security (English asset-backed security , abbreviated ABS).

Mortgage-backed securities backed by subprime mortgage loans played a major role in creating the real estate bubble until 2008 and the financial crisis that followed when it burst. This is why one speaks synonymously of the so-called subprime crisis .

Properties and classification

In contrast to Pfandbriefe , mortgage-backed securities do not appear in the balance sheet of the originating entity (e.g. a bank), as this transfers the pool of the covering assets to the issuing entity (a special-purpose vehicle ) for carrying out the securitization .

Because mortgage borrowers can repay early, the cash flows are not known in advance and can only be estimated. The early repayment (English prepayment ) represents a risk for the investor.

Mortgage-backed securities can be differentiated according to the type of real estate behind the collateral:

  • Commercial MBS (CMBS): These are backed by commercial real estate (such as residential complexes , retail and office buildings ).
  • Residential MBS (RMBS): These are secured by private residential real estate.

The properties of the Commercial MBS vary depending on the term. While the longer term loans (5 years or more) often have fixed rates and prepayment restrictions, there are shorter term loans (1-3 years) usually with floating rate and free prepayment.
