Market View

We believe commercial mortgage-backed securities (CMBS) have a number of structural and other features that may help the market weather the current volatility successfully.


In Brief

  • During the current market volatility, the commercial mortgage-backed securities (CMBS) market has seen notable spread widening, with some areas facing liquidity challenges.
  • But history has shown that CMBS defaults have been extremely rare, especially among senior tranches, and underwriting standards for CMBS have improved substantially from the pre-financial crisis environment.
  • CMBS are issued in a so-called “waterfall” structure, with each tranche within the structure carrying different levels of potential credit protection. Senior tranches, with higher credit ratings, carry the most credit enhancement.
  • We believe high-quality CMBS not only remain excellent credits, but also represent an attractive investment opportunity at current levels.


Over the last several weeks, U.S. fixed income markets have come under significant pressure as investors grapple with the COVID-19 virus and the associated restrictions likely to seriously dampen economic growth. Healthy markets sort through a myriad of data points to arrive at conclusions about asset values, and we can see that occurring across markets generally. However, we see some areas of the market that are also suffering through liquidity challenges that, while spurred by the current risk-off sentiment, do not reflect deeper credit concerns for the asset classes affected, in our view.

Commercial mortgage-backed securities (CMBS) certainly fit that description, in our opinion. The Option Adjusted Spread (OAS) on the benchmark Bloomberg Barclays Non-Agency CMBS Index, which had been as low as 84 basis points (bps) earlier in March 2020, spiked to 363 bps by March 25. While we believe some spread widening is justified based on the overall risk environment and the uncertainty surrounding the long term economic impact of COVID-19, in our view a large portion of the move has been driven by transient illiquidity in the fixed income markets. We believe high-quality CMBS not only remain excellent credits, but also represent an attractive investment opportunity at current levels.

What Are CMBS?
 are fixed-income securities backed by commercial real estate loans. Institutional borrowers, typically take out loans to finance the purchase of commercial property. A commercial lender (e.g., a commercial or investment bank) would lend the funds, and the property then is used as collateral for the loan, much the way a home would act as collateral to a residential mortgage.

Loan proceeds are used for a variety of property types, including apartment buildings, hotels, offices, retail stores, industrial properties, and hospitals. The rental income generated from the property’s occupants then flows through to the bond investors. Ultimately, CMBS provide an opportunity for investors to gain exposure to the commercial real estate market in a diversified manner through investment in securitized products, in lieu of a direct investment in property.

CMBS are typically backed by loans representing 40-80% of the value of the mortgaged property, with the balance representing equity, providing a meaningful cushion for owners of CMBS.

Potential Structural Protection
CMBS are issued in a so-called “waterfall” structure, with each level of the structure (known as a tranche) carrying different levels of potential credit protection. Senior tranches carry the most credit enhancement, around 30% at the AAA rating level, with potential protection declining down the structure. When losses occur, they accrue to the most junior tranches first and continue to do so until that tranche is depleted, with subsequent losses allocated to the next junior tranche in the same fashion, providing insulation to the senior tranches that can offer protection even in the case of a default with a subsequent sale of the property at a steep discount.


Table 1. Example of CMBS Structure

1Current ratings may be significantly lower. 2Legacy CMBS defined as bonds issues prior to 2009. 3CMBS 2.0 defined as bonds issued post 2009 through 2014. The mechanics and structure of assets in any portfolio may differ materially from those outlined above. Over time, as loans in the pool default, the subordination levels may change (defaults pick up, subordination levels fall). Therefore, the table above uses hypothetical subordination levels as they would be at the time of deal structuring.

Today, CMBS are considerably more conservatively structured than those that weathered the 2008-09 global financial crisis (GFC), providing what we believe is even greater structural protection to senior tranches. In addition, deal fundamentals have improved, with lower loan-to-value levels and better interest expense coverage.

But even the weaker “legacy” structures managed to survive the GFC with minimal defaults and even lesser losses realized by senior tranches. This came despite a very weak commercial real estate market that witnessed about a 40% top-to-bottom market decline from 2007 to 2009.

Current Environment
We believe that the majority of the recent spread widening in CMBS has been driven by the liquidity challenges facing fixed income markets generally. However, once the various programs that have been rolled out by the U.S. Federal Reserve (and perhaps others yet to come) effectively address liquidity issues, it’s clear in our opinion that the economic environment will, for a time, remain challenging. We believe this event is starkly different from 2008, however, in that the economic weakness is very likely to be over a relatively discrete time period. This is important for the decision making of the sponsors and special servicers in CBMS structures. They are likely to want to keep their options open--and the current structures of existing deals operating.

We’ve seen predictions of delinquencies for commercial real estate running anywhere from 15%-40%. While we think these estimates represent rather extreme outcomes, even if they were to come to pass, we believe senior pieces of CMBS structure would likely weather such a scenario without too much trouble. It’s important to recognize that delinquencies do not mean defaults--there is a process each mortgage would likely go through as payments are missed by the mortgagee which in many cases ensures cash continues to flow to bondholders.

Even if mortgages facing a longer-than-anticipated period of business interruption are unable to cure their loans by getting current and are thereby forced into default, because of the structural protection afforded to higher-quality tranches, properties would need to be liquidated at losses of 60% or more to impact the senior tranches of the structure. Such is the level of protection we believe is afforded investors at the top of the CMBS stack. We believe this combination of procedural and structural protections positions this asset class well to weather the COVID-19 slowdown.
