Cap Rate Spread

Also known as: risk premium spread, cap rate to Treasury spread

The difference between a property's capitalization rate and a reference interest rate — most commonly the 10-year U.S. Treasury yield — used as a shorthand measure of the risk premium investors demand for holding real estate versus a risk-free benchmark.

A widening cap rate spread generally signals either that real estate values are cheap relative to bonds (attractive entry pricing) or that investors are demanding greater compensation for real estate's illiquidity and operational risk relative to Treasuries; a compressed or negative spread, conversely, has historically preceded periods where real estate values are vulnerable to correction if interest rates rise and cap rates fail to keep pace. Spread analysis is most useful directionally and over time rather than as an absolute threshold, since 'normal' spread levels shift with property type, market, and credit cycle — industrial and multifamily have historically traded at tighter spreads than office and hospitality, reflecting perceived risk differences. Because cap rate spread compression was a major driver of past valuation dislocations when Treasury yields rose faster than cap rates adjusted, spread analysis has become a standard component of both acquisition underwriting and portfolio-level interest rate risk assessment.
