When the "Risk-Free" Rate Beats Your Rental Property
Treasuries are higher than the average rental cap rape for the first time in years.
By Paul Rubillo ·
My real estate investor friends may not like this topic I'm writing about today. The 10-year Treasury yield just climbed above the average rental cap rate.
That means the return you get for owning a piece of paper backed by the full faith and credit of the US government is now higher than the return you get for owning the average actual building with actual tenants paying actual rent.
What a cap rate actually is
For anyone who doesn't spend their day staring at real estate spreadsheets, the cap rate is a property's net operating income divided by its purchase price. It's the unlevered yield you'd earn buying a rental outright, no mortgage involved. A cap rate is a risk-versus-reward equation: real estate is illiquid, requires active management, comes with maintenance costs and vacancy risk, and can't be sold in an afternoon the way a bond can. Investors have always demanded a premium over the "risk-free" rate to take all of that on.
That premium is exactly what just disappeared.
The math that should be setting off alarms
Cap rates compress when property prices rise faster than rental income, or when investors are willing to accept less annual cash flow in exchange for appreciation potential. That's fine when the risk-free rate sits meaningfully below the cap rate; the spread compensates you for the headache of owning real estate. When the 10-year yield rises and cap rates don't rise with it, that spread narrows. When the 10-year actually crosses above the cap rate, the spread goes negative.
Right now, an investor can buy a Treasury with none of the illiquidity, none of the tenant risk, none of the maintenance headaches, and earn more doing it than owning a rental property outright. That's the risk premium math working in reverse, and it's the kind of dislocation that doesn't stay quiet forever.
Why this is happening now
The cause: sticky inflation, heavy Treasury issuance, and a Fed that hasn't been able to cut as aggressively as the market wanted. Meanwhile, cap rates have been slow to adjust because real estate pricing is sticky in the other direction. Sellers anchor to what their property was worth when rates were near zero, and it takes time (and often forced sellers) for prices to actually reset to reflect a higher-rate world.
The result is what we're seeing now: two markets that are supposed to move together. Except we now have long-duration bonds and long-duration real assets badly out of sync.
Why nobody's talking about it
Cap rate compression doesn't show up as a headline the way a stock market selloff does. There's no ticker flashing red. It shows up quietly, deal by deal, in the offering memorandums that don't pencil, the refinancings that don't clear, and the properties that sit on the market longer than sellers expect. It's the kind of story that's obvious in the data well before it's obvious in the news cycle, which is exactly why it deserves more attention than it's getting.
What has to give
Historically, this kind of inversion doesn't resolve gently. One of three things typically happens: property prices fall until cap rates rise back above Treasury yields, rental income has to grow enough to restore the spread organically, or Treasury yields eventually come back down and do the adjusting instead. Given everything we've talked about regarding sticky inflation and what it would actually take for yields to keep climbing, I wouldn't bet heavily on option three happening quickly.
That leaves price discovery in commercial and residential rental real estate as the more likely release valve, and price discovery in a market that's been slow to reprice tends to be an uncomfortable process for whoever's holding the asset when it happens.
The bottom line
A negative spread between the risk-free rate and the cap rate on a risky, illiquid asset is not a sustainable equilibrium. It's a signal that one side of that equation is mispriced, and markets eventually correct mispricing. Right now, the correction is happening quietly, deal by deal, while most of the financial conversation stays fixated on stocks and the Fed. That's exactly the kind of setup worth paying attention to before it becomes the headline instead of the footnote.
