Mortgage Backed securities (MBS) are financial instruments that link the real estate market with the broader investment ecosystem. They are created by pooling multiple home loans or real estate-backed debts, which are then converted into tradable securities and offered to investors. In return, investors receive periodic income from the principal and interest repayments made on the underlying loans.
MBS provide investors with relatively stable income streams while allowing financial institutions to release capital, improve liquidity, and manage risk exposure more efficiently. By supporting continuous lending activity, they play an important role in sustaining the housing finance system. For both investors seeking long term returns and borrowers exploring options such as a loan against property, understanding how MBS work helps in making more informed financial decisions.
What are mortgage backed securities (MBS)?
Mortgage Backed Securities, commonly known as MBS, are investment instruments that represent ownership in a pooled collection of residential or commercial mortgage loans. Banks and financial institutions bundle individual mortgages together and sell them as tradable securities to investors. In return, investors receive regular income from the interest and principal repayments made by borrowers.
Most MBS are structured as pass-through securities, where the cash flows from the underlying loans are distributed directly to investors. Based on the underlying assets and issuers, MBS can be classified into agency MBS backed by government-sponsored entities, non-agency MBS issued by private institutions, and residential or commercial MBS, depending on the type of property involved. While MBS offer steady returns and help maintain liquidity in the housing market, they also carry risks such as prepayment risk and borrower default.
From a broader lending perspective, similar securitisation principles apply to products like a loan against property. Property-backed loans can be pooled to improve liquidity and risk management for lenders, while borrowers benefit by unlocking the value of their property for immediate financial needs. Understanding how MBS work helps investors and borrowers alike make informed decisions within the real estate and finance ecosystem.
How do mortgage-backed securities work?
To understand how mortgage-backed securities work, it helps to look at the step-by-step process behind their creation.
- Origination: Banks and NBFCs provide home loans to borrowers, with the purchased properties serving as collateral for these mortgages.
- Pooling: The financial institutions then group multiple mortgages that share similar features such as loan tenure, interest rate, and repayment structure.
- Securitisation: These pooled mortgages are sold to a trust or special purpose vehicle (SPV), which may be managed by a government-backed enterprise or a private entity. The trust converts these loans into tradable securities—known as MBS.
- Issuance: The MBS are issued and offered to investors. Agency-backed MBS are guaranteed by government organisations, providing an additional layer of security.
- Servicing: A mortgage servicer manages the collection of monthly repayments from borrowers and ensures that principal and interest payments are passed on to MBS investors.
- Investment: Investors buy these MBS, indirectly lending funds to homebuyers. In return, they receive regular payments drawn from the mortgage pool’s cash flows, consisting of both principal and interest components.
Purpose of MBS
Mortgage-Backed Securities (MBS) serve different objectives for lenders and investors within the financial system.
- For Lenders: MBS enable financial institutions to sell their existing mortgage loans, freeing up capital to issue new loans. This enhances liquidity and allows lenders to expand their lending capacity.
- For Investors: MBS provide investors with an opportunity to participate in the real estate market without directly owning property. They earn regular income from the interest and principal payments of the underlying mortgage pool.
Types of mortgage backed securities
There are several types of mortgage-backed securities, including:
- Pass-through securities: These securities pass through the principal and interest payments from the underlying mortgage loans directly to the investors.
- Collateralised mortgage obligations (CMOs): CMOs divide the cash flows from the underlying mortgage loans into multiple tranches, each with different risk and return characteristics.
- Stripped mortgage-backed securities: These securities separate the principal and interest payments of the underlying mortgage loans into different securities, catering to investors with specific preferences for cash flow timing.
Risks of mortgage-backed securities
Mortgage-backed securities (MBS) are investment instruments backed by pools of home loans. While they offer attractive returns, they carry several risks that investors must consider.
- Credit risk: MBS depend on homeowners making timely mortgage payments. If borrowers default, the cash flow to investors may be disrupted, leading to losses.
- Interest rate risk: Changes in interest rates can affect MBS value. Rising rates may reduce prepayments, while falling rates can lead to early repayments, altering expected returns.
- Prepayment risk: Homeowners may refinance or pay off loans early, causing investors to receive principal sooner than expected, potentially reinvesting at lower yields.
- Liquidity risk: Some MBS may be difficult to sell quickly without affecting price, especially in volatile markets.
- Market and economic risk: MBS are sensitive to economic downturns, housing market declines, and changes in regulatory policies, which can significantly impact performance.
Advantages of investing in mortgage-backed securities
Investing in mortgage-backed securities (MBS) offers several advantages:
- Stable cash flows: MBS provides a steady stream of income through the interest and principal payments from mortgage loans.
- Diversification: MBS allows investors to diversify their portfolios by gaining exposure to the real estate market without directly owning property.
- Relative safety: MBS issued by government-sponsored entities or reputable financial institutions are often considered relatively safe investments due to their backing.
Quick Comparison: Agency vs. Non-Agency of mortgage backed securities (MBS)
Agency MBS are issued or guaranteed by government-sponsored enterprises like Fannie Mae or Freddie Mac, offering lower credit risk. Non-Agency MBS are privately issued, carry higher yields, but involve greater credit and default risk.

Risks associated with mortgage-backed securities
Like most investment instruments, Mortgage-Backed Securities (MBS) carry certain risks that can influence returns and market value.
- Interest rate risk: Changes in interest rates can alter homeowner repayment behaviour, affecting the timing and amount of cash flows to MBS investors.
- Credit risk: Defaults on the underlying mortgage loans, particularly in subprime or non-conforming segments, can lead to losses for investors.
- Prepayment risk: Borrowers may choose to repay or refinance their mortgages early, disrupting expected cash flows and reducing potential returns.
- Extension risk: When interest rates rise, fewer homeowners refinance, which can extend the duration of the MBS and impact liquidity.
- Market and liquidity risk: Price volatility and limited liquidity in certain types of MBS can make them harder to trade during market stress.
Key players in the mortgage-backed securities market
The mortgage-backed securities market involves various participants, including:
- Mortgage originators: These are financial institutions that originate and underwrite mortgage loans.
- Government-backed entities: In India, entities like the National Housing Bank (NHB) play a significant role in the MBS market by purchasing, guaranteeing, and securitising mortgage loans.
- Investors: Institutional investors, such as pension funds, mutual funds, and insurance companies, are major participants in the MBS market, seeking to earn returns on their investments.
MBS and the 2008 Financial Crisis
Mortgage-Backed Securities (MBS) were a key factor in the 2008 global financial crisis. The bundling of high-risk subprime mortgages into MBS pools resulted in widespread defaults when borrowers failed to meet repayment obligations. This led to significant losses for investors and triggered a ripple effect across global financial markets.
The crisis highlighted shortcomings in credit evaluation and risk management practices, prompting governments and regulators to implement stricter rules for mortgage lending, securitisation, and investor protection within the MBS market. These reforms aimed to enhance transparency, reduce systemic risk, and restore confidence in the financial system.
How to invest in mortgage-backed securities?
Investors can access the mortgage-backed securities market through various channels, including:
- Direct purchase: Investors can buy MBS directly from issuers or through brokerage firms.
- Exchange-traded funds (ETFs): ETFs provide a convenient way to invest in a diversified portfolio of MBS, offering liquidity and transparency.
- Mutual funds: Mutual funds specialising in MBS offer investors professional management and diversification across a range of mortgage-backed securities.
