Mortgage-Backed Securities in Tranches: A Guide for beginners

Residential Mortgage-Backed Securities (RMBs) consist of units of mortgages grouped and offered to investors as bonds. The bonds are therefore made up of several collateralized mortgage obligations called tranches.


RMBs are low-risk investments. From our specialist assessment of Property Valuation (Residential, Commercial, and Industrial) at GANTPMV, It is of record that no individual has reported a loss of their investment capital due to a default in prime residential mortgage-backed security in Australia. Not even a dollar was lost.


Residential Mortgage-Backed Securities (RMBs) are debt-based security secured by interest payment on loans for residences. As earlier said, RMBS are low-risk debt-securities. This risk is minimized through a pool of residential mortgages to mitigate the risk of default by an individual.


Ten percent (10%) of every home loan is financed through RMBs. Corporate and financial institutions like banks mostly subscribe to residential mortgage-backed securities. RMBs enable these institutions to fund mortgage loan requests from their customers and grant investors access to the residential mortgage market.


Mortgage loans hold down paid capital. This is because loans for mortgages are transactions that remain in the balance sheet of deposit money banks throughout the home loan. The pooling of several mortgage loans into a “collateralized instrument” or “security” free up the capital held down by home loans. Hence the capital is taken off the balance sheet of the lender and ready for use.


These residential mortgage-backed securities are debt-based securities that earn investors interest from the pool of residential mortgages and can be bought by investors from financial institutions. Investors receive their interest as the mortgages are repaid. Investors’ ROI (Return On Investment) is determined by the frequency of repayments of the home loans from the pool or set of collateralized mortgage obligations called tranches.


The meaning of a Tranche

Tranche is a French word that means portion, series or slice. In transaction documents, tranches are referred to as various “classes” of notes. Each class of note has different rights and are classified, for instance, as Class A, Class B and Class C notes.


Tranches are series of home loans packaged and offers to investors for sale. The estimated value of a home loan is $250,000. These home loans are packaged together in groups. They are then offered to investors for sale as Residential Mortgage-Backed Securities bonds in groups of hundreds or thousands. The RMB bonds are made up of several tranches. Each tranche has its credit rating and is rated based on seniority by rating agencies. On average, residential mortgage-backed securities have an estimated value of $500 million to $1 billion.


An investor’s interest in a tranche is based on the investor’s investment objective and the risk rating of the tranche. An investment option with a relatively lower risk (and less interest) may purchase the higher tranches. The higher tranches are isolated from the credit default of the pool of mortgage-backed securities. In the case of a credit default, the losses are first allocated to the tranches below the higher tranches, that is, the lower tranches.


The lower tranches are a riskier investment option since there are no other tranches below them. That is why the lower tranches have a higher rate of return on investment. An investor’s risk appetite determines the type of tranche (higher or lower) he is willing to invest in.


A typical Investment Fund

An investment fund that enables investors to access residential mortgage-backed securities, which can only be accessed by financial institutions. To qualify, an investor must be willing to hold their investment portfolio for at least three years. Investors are not charged any fees.


With a minimum of $10,000, you can invest. The investment fund has an estimated loan to valuation ratio (LVR) of less than 0.8, and it consists of three forms of tranche which is classified as follows:


Tranche A

Ninety percent (90%) of residential mortgage-backed securities pools are made up of Tranche A. It has a possible risk rating with an ROI of 1.5% above BBSW (Bank Bill Swap Reference Rate).


Tranche AB

The pool of RMBs comprises 7% of Tranche AB mortgage-backed securities with an ROI of 2.5% above BBSW.


Tranche B

Three percent (3%) of the RMBS pool consist of Tranche B securities with an ROI of 4% above the BBSW.


From the above tranches, it is evident that investors invest in higher tranches and lower tranches for liquidity and yield, respectively. Funds invested in Tranche B notes. Tranche B notes have a Category 2 risk rating with a high potential of fund expectancy. Why the excellent rating? Tranche B losses are absorbed by the tranches below it and the debtor’s equity; and mortgage insurance from insurers.
