Target range — no historical percentile applies

10Y TIPS real yield
The yield on 10-year Treasury Inflation-Protected Securities — the return investors receive above inflation for lending to the U.S. government over 10 years. Because TIPS principal adjusts for inflation, the yield provides a market-based measure of the real, inflation-adjusted interest rate.

10Y–2Y slope
The difference between the 10-year and 2-year Treasury yields. Positive means longer-term rates are higher than shorter-term rates; negative ("inverted") means the opposite.
