Cap Rates vs. Interest Rates

Interest rates are linked to cap rates because fixed-income government securities and real estate are both financial assets competing for investment dollars and generally move in tandem to some degree. The spread between real estate cap rates and “risk-free” Treasury yields is generally considered to be an inverse indicator of risk tolerance—lower spreads reflect higher risk appetite and optimism related to future revenue and value. This analysis compares 10-Year U.S. Treasury yields to NAREIT All Equity REIT implied cap rates from 2000–2025, including the spread between them, and examines the time lag between changes in interest rates and corresponding movement in real estate transaction pricing.

Interest Rates vs. Implied All REIT Cap Rates, 2000–2025

Key Takeaways

Context & Discussion

Lending interest rates are typically based on a spread over U.S. Treasuries of a corresponding maturity. For example, the interest rate for a five-year loan with a 1.5% spread over the 5-Year UST of 4.0% would equal 5.5%. Short-term interest rates are essentially determined by the Federal Reserve, while longer-dated bonds are increasingly influenced by market forces, although the Federal Reserve also conducts open market operations to influence the long end of the yield curve.

The relationship between cap rates and interest rates is also influenced by timing. U.S. Treasuries constitute the largest and most liquid market in the world and trade instantaneously with complete price transparency. Real estate transactions, on the other hand, are subject to significant delays related to loan covenants, tax considerations, and a host of other factors. The typical time period from decision to sell through closing can range up to a year or more and generally averages around six months. In addition to the time required to complete a transaction, there are often multiple partners involved in the decision-making process, each reacting to market forces and individual preferences.

Correlation — 10 Yr UST vs. All Equity REIT Cap Rates

As reflected in the correlation analysis above, comparing implied cap rates to 10-Year UST yields with a two-year delay produces a substantially higher correlation (79%) than the same-year comparison (71%). Inflation and interest rates are naturally related because investors require higher yields on fixed-rate securities to keep pace with rising prices during inflationary periods and settle for lower yields when inflation is low. However, the causal relationship between these variables is less straightforward than conventional wisdom might suggest. The Federal Reserve uses interest rates to control inflation primarily because it has limited tools at its disposal, as reflected by former Federal Reserve Chairman Ben Bernanke: “Monetary policy is a blunt tool, not a scalpel. It can’t fine-tune economic outcomes with precision.”

Beyond Interest Rates: The Role of Capital Liquidity

While interest rates are the most commonly cited driver of cap rate movements, research suggests that capital flows and liquidity conditions can be equally influential. In a widely cited analysis, Dr. Peter Linneman and co-authors found that capital flows “play a significant role in driving cap rates, given that availability of capital and increased competition for assets will significantly impact real estate asset values.” This helps explain why the current environment of elevated Treasury yields has coincided with cap rate spreads compressing to 25-year lows rather than widening as a simple interest rate model would predict. The answer lies in the enormous volume of investable capital seeking returns. Global private equity dry powder reached a record $2.6 trillion in mid-2024, with more than $500 billion earmarked for real estate. Open-end core fund redemptions have slowed, and both traditional and alternative lenders are actively competing for CRE loan originations. As PwC and the Urban Land Institute noted in their Emerging Trends in Real Estate 2026 report, “There’s an incredible appetite to put out debt. Once equity finds a transaction point, the debt is ready to go.” This wall of capital puts persistent downward pressure on cap rates regardless of where Treasury yields sit, at least until a credit event or recession triggers risk aversion and capital withdrawal—as occurred during the GFC when spreads widened from 166 bps to 479 bps in just two years.
