Soaring Interest Rate Cap Costs Squeeze Floating-Rate CRE Borrowers

By Majid Radaei, RadCRE · · Market Updates

Rising SOFR volatility and increased bank capital requirements have driven interest rate cap costs up by over 300% since 2022, compounding challenges for floating-rate CRE loans.

Interest Rate Cap Costs Explode, Burdening CRE Borrowers

Commercial real estate (CRE) borrowers, particularly those with floating-rate debt tied to the Secured Overnight Financing Rate (SOFR), are grappling with a significant surge in the cost of interest rate caps. These financial instruments, essential for mitigating exposure to rising interest rates, have become a major point of concern, exacerbating already tight lending conditions and putting pressure on property cash flows.

Several factors are contributing to this dramatic escalation. The prolonged period of higher interest rates, coupled with increased volatility in SOFR, has made cap providers—typically large commercial banks—more cautious. Furthermore, enhanced regulatory capital requirements under Basel III and other frameworks have increased banks' cost of capital for derivative products. According to an industry report by Savills, the cost of a three-year, 500-basis-point SOFR cap has more than tripled since early 2022, with some market participants reporting cap prices increasing by over 300% for comparable structures.

Impact on Bridge Loans and Value-Add Strategies

The impact is most acutely felt by borrowers utilizing bridge loans, common in value-add strategies and distressed asset acquisitions, which often feature SOFR + 300-600 bps pricing. Lenders typically mandate interest rate caps for these loans to protect their exposure to rate spikes, especially as SOFR currently hovers around 4.31%. For a $50 million floating-rate loan, a 300% increase in cap costs can easily translate into millions of dollars in upfront expenses, directly reducing available equity for property improvements or debt service reserves.

For example, a borrower financing a hotel acquisition in Phoenix with a $30 million bridge loan might have budgeted $300,000 for a rate cap in 2022. Today, that same cap could cost upwards of $900,000 or more, a significant and often unexpected drain on capital. This phenomenon was highlighted recently by Trepp, noting how these additional costs are contributing to debt service coverage ratio (DSCR) challenges for many borrowers.

RadCRE Perspective

"The explosion in interest rate cap costs is a silent killer for many floating-rate CRE deals right now, especially in the hospitality sector where cash flows are still stabilizing. Many sponsors underwrote their deals in 2021 or early 2022 when caps were a fraction of the price they are today. We're seeing clients struggle to find economically viable cap solutions for new acquisitions or bridge loan extensions. It's not just the SOFR rate itself that's the problem; it's the premium for protection against it. This forces some sponsors to take on more risk without a cap, which is reckless, or walk away from otherwise good deals. At RadCRE, we're advising clients to model multiple cap cost scenarios upfront and explore alternative structures like fixed-rate agency debt for multifamily or SBA programs for owner-occupied hotels if their business plan allows. Sometimes a shorter cap term or a higher strike rate is the only way to make the numbers pencil, but that means taking on more exposure. It’s a delicate balance and requires deep financial modeling to truly understand the risk adjusted return on capital."

Navigating the Current Landscape

The elevated cost of interest rate caps is adding another layer of complexity to CRE financing. This is prompting some borrowers to explore alternative financing structures or to reassess their leverage strategies. Some are opting for shorter-term caps (e.g., 12-18 months) rather than the typical 2-3 year terms, hoping that rate volatility subsides and cap premiums decrease in the near future. Others are looking at higher strike rates, which lowers the upfront cap cost but increases the potential future debt service burden if SOFR rises significantly.

The trend underscores the importance of sophisticated financial modeling and proactive risk management in today's dynamic CRE capital markets. RadCRE assists clients in navigating these challenges by providing comprehensive capital advisory services and leveraging our RadCRE.ai platform to analyze complex debt structures, including the intricate costs and implications of interest rate caps.
