CMBS Market Navigates Maturing Debt & Defeasance Challenges

Rising rates challenge CMBS defeasance strategies and loan maturities, with specific sectors showing distress and the overall market bracing for refinancing hurdles.

CMBS Market Faces Headwinds: Maturities and Defeasance in Focus

The commercial mortgage-backed securities (CMBS) market continues to navigate a complex landscape characterized by higher interest rates, economic uncertainty, and a looming wave of loan maturities. As of Q1 2026, concerns are mounting over the ability of borrowers to refinance loans originated in a historically low-interest-rate environment, particularly as these come due.

Maturing Debt and Refinancing Pressures

According to data from Trepp, an estimated $900 billion in commercial real estate debt is set to mature between 2025 and 2027, with a significant portion encapsulated within CMBS structures. This poses a substantial refinancing challenge, especially for properties with weakened financials or those in sectors particularly sensitive to interest rate hikes and shifting demand, such as older office assets and certain retail segments.

The average interest rates for new CMBS originations have significantly increased. While CMBS spreads for high-quality assets might be seen at T+200-250 basis points, the underlying Treasury rates are far higher than a few years ago. With the benchmark SOFR hovering around 4.31% and Prime at 8.50%, borrowers face substantially higher debt service payments upon refinancing. This often leads to a 'payment shock' or a 'value gap,' where property values have compressed, making it difficult to secure new financing at the same LTVs or even cover the existing debt amount.

Defeasance Trends and Challenges

Defeasance, a common exit strategy for CMBS borrowers looking to sell or refinance their properties before loan maturity, has become notably more expensive and complex. Defeasance involves substituting the existing mortgage collateral with U.S. Treasury securities that generate sufficient cash flow to cover the remaining debt service payments. Historically, in a declining or stable interest rate environment, defeasance costs could be manageable. However, with elevated interest rates, the cost to purchase sufficient Treasury securities to match future loan payments has surged.

For instance, a borrower with a $50 million CMBS loan originated in 2017 with a 4% coupon rate looking to defease today faces significantly higher costs. The yield curve inversion and overall higher Treasury yields mean a larger principal investment is required to generate the original coupon payments. This has led many borrowers to reconsider early exits or to explore alternative, more costly financing solutions like mezzanine debt or preferred equity to bridge the gap, often at rates ranging from 12-18%.

Public filings indicate that defeasance activity has slowed compared to previous years, especially for larger loan sizes. Borrowers are increasingly opting for loan assumptions if possible, or bracing for maturity events where lenders may be forced to extend or work out terms, particularly on performing loans rather than risk foreclosure in a softer market.

Property Type Performance in CMBS

While the overall CMBS market faces pressure, performance varies significantly by property type. Hospitality and multifamily CMBS loans have generally proven more resilient, benefiting from robust travel demand and strong rental fundamentals, respectively. For example, recent reports by STR indicate continued RevPAR growth in many leisure and business travel markets, supporting hotel cash flows.

Conversely, the office sector remains the primary concern. Trepp data shows that office delinquency rates within CMBS pools continue to climb, reflecting the impact of remote work and declining property valuations. This distress is contributing to an increase in special servicing transfers, signaling deeper issues for these assets.

RadCRE Perspective

Majid Radaei, Founder of RAD Commercial Realty, notes, "The CMBS market right now is a tale of two cities. On one hand, you have performing assets, particularly in hospitality and well-located multifamily, where even with higher rates, cash flows are covering debt service. For these owners, the challenge is purely economic—can they find new debt that preserves their equity?

However, the real pressure point is office. We're seeing CMBS loans on older, less-amenitized office buildings hit maturity with a significant value gap. Defeasance is often prohibitively expensive today, sometimes costing north of 20% of the loan balance. This means borrowers are either forced to pump in substantial new equity, which is hard to justify for a struggling asset, or face special servicing.

At RadCRE, we're actively advising clients to understand their true cost of capital for refinancing. Bridge loans, while expensive at SOFR + 300-600 bps, can be a short-term solution to buy time for asset repositioning. For hospitality clients, we're seeing strong demand for agency debt (Fannie/Freddie) and even SBA 7(a) for owner-operators, which can offer more attractive long-term rates than CMBS alternatives, even with upfront fees. The key is proactive planning and realistic valuations. Banks are tightening, so alternative capital — mezzanine or preferred equity, even from family offices — is stepping in, but at a significant cost. Don't wait until the last minute to explore your options; the market is not forgiving of complacency right now."

Outlook

The CMBS market will continue to be closely watched as the wave of maturities accelerates. Investors, lenders, and borrowers are all adapting to a 'higher for longer' interest rate environment, leading to more conservative underwriting and a re-evaluation of risk premiums across property types. Strategic asset management, timely capital injections, and creative financing structures will be crucial for navigating the current landscape.
