Nominal Vs. Real Treasury Yields: A Primer

 | Sep 29, 2022 08:57AM ET

Real (inflation-adjusted) yields have surged in recent weeks, raising the question of whether it’s timely to buy inflation-indexed Treasuries (a.k.a. TIPS).

Maybe, but before you dive in, keep in mind that real Treasury yields represent a particular mix of opportunity and risk that contrasts with standard Treasuries. Accordingly, it’s crucial to pick the right tool based on what you’re looking to achieve (or avoid) at the right time.

Superficially, nominal and real Treasury yields appear to be more or less identical except that nominal trades consistently at a premium over real, as shown by the 10-year maturities over the past two decades (see chart below). On that basis, a naïve view would always choose nominal Treasuries because the payout is higher. But that’s the wrong way to compare these two yields.
