CMBS Market Navigates Elevated Interest Rates and Defeasance Shifts

By Majid Radaei, RadCRE · 2026-04-08 · Industry Insights

The CMBS market faces ongoing challenges and shifts in defeasance trends as elevated interest rates impact commercial properties, with delinquency rates like multifamily CMBS loans rising to 2.1% in Q1 2026.

CMBS Market Conditions Amidst Rate Volatility

The commercial mortgage-backed securities (CMBS) market continues to navigate a landscape defined by higher-for-longer interest rates and evolving property fundamentals. While the broader capital markets have shown signs of stabilization compared to the volatility of 2023, the CMBS sector remains under pressure, particularly for assets in struggling sectors like office and certain retail segments. According to Trepp data, the overall CMBS delinquency rate, which includes loans 30+ days delinquent, rose slightly to 5.02% in March 2026, up from 4.90% in February. This increase is largely driven by persistent stress in the office sector, where the delinquency rate surged past 8.0% for the first time since the pandemic's onset.

New issuance of CMBS has seen a modest rebound, with approximately $12 billion in conduit CMBS priced in Q1 2026, a significant increase from the subdued levels of late 2023 but still well below pre-pandemic averages. Spreads for benchmark 10-year CMBS are currently hovering around T+175-225 bps for investment-grade tranches, indicating a more cautious investor sentiment than in lower rate environments. Property types such as industrial and high-quality multifamily continue to attract investor confidence, reflected in tighter spreads and more robust loan-to-value ratios within these CMBS deals. Conversely, hospitality CMBS, while having largely recovered from pandemic lows, faces scrutiny regarding individual property performance and re-tenanting risk in select-service portfolios.

Defeasance Trends and Strategies in a High-Rate Environment

Defeasance, a common method for borrowers to release collateral from a CMBS trust prior to loan maturity, has traditionally been driven by refinancing opportunities or property sales. In the current high-interest rate environment, where the SOFR benchmark is around 4.31% and the Prime rate is 8.50%, the economics of defeasance have become more complex and often more costly. Borrowers typically purchase a portfolio of U.S. Treasury securities that generate sufficient cash flow to cover the remaining debt service payments of the defeased loan. When Treasury yields are significantly lower than the coupon rate on the existing CMBS loan, the cost of purchasing these securities can be substantial.

Recent data from MSCI RCA indicates a noticeable slowdown in defeasance activity compared to the peak years of 2021-2022. Many borrowers who locked in historically low fixed-rate CMBS loans years ago are facing maturity walls in 2026-2027. The current market often presents a challenge: either refinance at significantly higher rates (e.g., bridge loans at SOFR + 300-600 bps or new CMBS at T + 175-225 bps), or pursue defeasance which may now be prohibitively expensive due to the 'yield maintenance'-like effect of buying low-yielding Treasuries to cover a higher-coupon loan. This has led to an increase in loan modifications, extensions, and, in some cases, defaults, particularly when asset valuations have declined. For example, a recent defeasance transaction for a Dallas office property valued at $75 million carried an estimated defeasance cost exceeding 8% of the outstanding loan balance, making it a difficult pill for the borrower to swallow.

RadCRE Perspective

"The CMBS market today is a tale of two cities: robust for well-performing assets in favored sectors, and increasingly fraught for others. We're seeing a critical re-evaluation of loan terms and lender appetites. For borrowers facing CMBS maturities in this environment, simply extending or refinancing at current rates can be value-dilutive. The 'defeasance dilemma' is very real; it's no longer the clear-cut solution it once was. Many borrowers are caught between a rock and a hard place: defease at a steep premium or refinance into a market with SOFR still elevated and spreads widening for perceived riskier assets.

Our approach at RAD Commercial Realty is to evaluate the entire capital stack and the asset's true operational potential. For instance, in hospitality, we're keenly advising clients to look beyond just the coupon rate and consider the impact on cash flow and exit value. For a select-service hotel with strong RevPAR growth hitting a CMBS maturity, a strategic recapitalization potentially involving preferred equity or a bridge-to-perm loan might be more accretive than a costly defeasance. We're guiding clients through complex negotiations, leveraging our relationships with alternative lenders who can structure flexible solutions, often at pricing between traditional bank debt and pure equity – for example, mezzanine debt at 12-18% or structured preferred equity tailored to the asset's business plan. It's about creative financing and understanding how to unlock value when traditional avenues are constrained, especially as the cost of capital remains significantly higher than just two years ago." – Majid Radaei, Founder of RAD Commercial Realty

As the market continues to absorb the impact of monetary policy, the evolution of CMBS performance and defeasance strategies will remain a critical indicator of broader commercial real estate health. RAD Commercial Realty stands prepared to assist clients in navigating these complex capital market dynamics, structuring optimal financing solutions, and identifying compelling investment opportunities across all asset classes, particularly in hotel investment sales, CRE financing, and value-add acquisitions.
