Commercial mortgage-backed securities are investments backed by loans on commercial properties like offices, hotels, and shopping centers.
Commercial mortgage-backed securities, often shortened to CMBS, may sound complicated at first, but the idea is simpler than it seems. These securities are created when lenders bundle together multiple commercial real estate loans and sell them to investors. The cash flow from the borrowers’ loan payments is then passed along to the investors who buy the securities.
If you’ve ever wondered how banks free up money to grant more real estate loans — or how investors gain access to big commercial properties without owning them directly — commercial mortgage-backed securities play a big part in that process. Let’s break it all down in simple, friendly language.
What Are Commercial Mortgage-Backed Securities?
Commercial mortgage-backed securities are a type of mortgage-backed investment that is supported by loans on commercial properties. These properties can include:
-
Office buildings
-
Retail centers
-
Hotels
-
Warehouses
-
Apartment complexes
-
Industrial properties
Instead of a single loan backing the security, a CMBS typically contains dozens or even hundreds of commercial loans. These loans are packaged into a financial product and sold to investors, who then receive payments based on the interest and principal collected from the businesses that borrowed the money.
How Do Commercial Mortgage-Backed Securities Work?
The process usually happens in a few steps:
1. A lender issues commercial property loans
Banks, insurance companies, or other lenders provide loans to businesses buying or refinancing commercial real estate.
2. These loans are bundled together
Instead of holding the loans long-term, the lender groups many of them into one large pool.
3. The pool is turned into securities
This pool of loans becomes the foundation for commercial mortgage-backed securities. Investors buy pieces of this pool.
4. Investors receive payments
As the businesses make their monthly loan payments, the cash flow is distributed to investors. The interest from the loans becomes the investors’ return.
This setup benefits both sides: lenders free up capital to issue more loans, and investors gain access to steady income from commercial real estate — without owning or managing the property themselves.
Why Do Investors Buy Commercial Mortgage-Backed Securities?
Investors are often attracted to CMBS because they offer:
Steady income
Loan payments come in regularly, so CMBS can provide a predictable stream of cash.
Diversification
Since each security contains many loans from different borrowers and property types, investors spread their risk across a wide range of commercial properties.
Higher potential returns
Compared to some other fixed-income investments, CMBS may offer better yields, especially when backed by strong commercial properties.
What Risks Come With CMBS?
Like any investment, commercial mortgage-backed securities carry risks. Some of the most common include:
Credit risk
If businesses fail to make loan payments — for example, if a hotel loses customers or a mall sees fewer tenants — investors might receive less income.
Commercial real estate market fluctuations
Economic downturns, rising vacancy rates, or declining property values can affect the performance of the loans in the pool.
Complex structure
CMBS often come in “tranches” or layers, each with different levels of risk and return. Lower-risk tranches usually pay less, while higher-risk ones pay more but face greater chance of loss.
Because of these risks, CMBS are usually best suited for investors who understand real estate markets or who work with a financial advisor.
Who Uses Commercial Mortgage-Backed Securities?
Commercial mortgage-backed securities are widely used by:
-
Institutional investors (pension funds, insurance companies)
-
Investment firms
-
Real estate investment portfolios
-
Banks seeking steady fixed-income assets
They offer a way to invest in large commercial buildings without directly owning or managing them — making CMBS a convenient tool for diversification.
Commercial mortgage-backed securities play an important role in the real estate and investment world. They help lenders free up money to issue more commercial loans, and they give investors a chance to earn income from major commercial properties. While CMBS can offer attractive returns, it’s important to understand the risks and how they work before investing.
