Mortgage-Backed Securitisation

Mortgage-backed securitisation refers to the financial process through which housing loans are pooled together and converted into marketable securities that can be sold to investors. In the Indian banking and financial system, mortgage-backed securitisation is an important mechanism for improving liquidity, managing risk and supporting the expansion of housing finance. Its development reflects India’s broader efforts to deepen financial markets while maintaining systemic stability.

Concept and Meaning of Mortgage-Backed Securitisation

Mortgage-backed securitisation involves transforming illiquid housing loan assets held by banks or housing finance companies into tradable financial instruments. Instead of holding mortgage loans on their balance sheets until maturity, lenders package these loans into pools and sell the cash flow rights to investors.
The repayment of principal and interest by individual home loan borrowers generates cash flows, which are passed on to investors in proportion to their holdings. This process enables lenders to convert long-term receivables into immediate funds.

Rationale in the Indian Context

Housing finance in India is characterised by long tenures and stable but slow-moving cash flows. This creates asset–liability mismatches for banks, which rely heavily on short- and medium-term deposits.
Mortgage-backed securitisation addresses these challenges by:

• Improving liquidity for lenders
• Releasing capital for fresh lending
• Reducing balance sheet concentration in housing loans

It supports the expansion of housing credit without excessive reliance on deposit growth or government support.

Regulatory Framework

Mortgage-backed securitisation in India is governed by guidelines issued by the Reserve Bank of India. The regulatory framework emphasises prudence, transparency and alignment of incentives between originators and investors.
Key regulatory features include:

• Minimum holding period and minimum retention requirements
• Restrictions on complex or opaque securitisation structures
• Detailed disclosure and due diligence standards

These measures are designed to prevent excessive risk transfer and ensure that lenders retain a stake in loan performance.

Structure and Process

The securitisation process typically begins with a bank or housing finance company identifying a pool of eligible housing loans. These loans are transferred to a bankruptcy-remote special purpose vehicle, which issues securities backed by the mortgage pool.
Investors purchase these securities and receive periodic payments derived from borrower repayments. Credit enhancement mechanisms such as over-collateralisation, cash reserves or third-party guarantees may be used to improve the credit profile of the securities.

Role in Banking and Balance Sheet Management

For banks and housing finance companies, mortgage-backed securitisation is a strategic balance sheet management tool. By selling securitised assets, lenders can reduce long-term exposure, improve capital adequacy ratios and enhance return on equity.
This flexibility enables banks to manage growth while complying with prudential norms, particularly during periods of strong housing loan demand.

Importance for Housing Finance

Mortgage-backed securitisation supports the housing sector by ensuring a steady flow of funds into housing finance. As lenders recycle capital through securitisation, they can extend more home loans, including to first-time buyers and middle-income households.
This mechanism complements direct lending and mortgage guarantee arrangements, strengthening the overall housing finance ecosystem.

Contribution to the Indian Economy

The housing sector has strong multiplier effects on employment, infrastructure and industrial activity. By facilitating the flow of long-term funds into housing, mortgage-backed securitisation indirectly supports economic growth and job creation.
It also promotes capital market development by offering investors exposure to relatively stable, long-term assets linked to residential mortgages.

Risk Distribution and Financial Stability

One of the key advantages of securitisation is the distribution of credit risk across a wider set of investors. This reduces concentration of risk on bank balance sheets and enhances resilience of the financial system.
However, poorly regulated securitisation can amplify systemic risk. India’s conservative regulatory approach aims to balance risk transfer with accountability, ensuring that securitisation strengthens financial stability rather than undermining it.

Relationship with Mortgage-Backed Securities

Mortgage-backed securitisation is the process that results in the creation of Mortgage-Backed Securities. While the securitisation process focuses on pooling and structuring loans, the resulting securities represent the investment instruments held by market participants.
Together, they form a key link between the banking system and capital markets.
