Real (TIPS) · Level/Slope/Curvature · 2 Oct 2026
10Y 2.92%
Principal components are the few shapes that account for most of how a curve moves.
Real (TIPS) decomposed into 3 components over 4 Oct 2021 to 2 Oct 2026, fit on 5 maturities (5Y, 7Y, 10Y, 20Y, 30Y), explaining 99.9% of variance.
TIPS real yields: the return Treasury bonds pay above inflation once their inflation-linked principal is stripped out.
Principal components are the few shapes that account for most of how a curve moves. The biggest three are a level shift, a slope tilt and a curvature bend.
Every line is a score, not a rate. Zero is the average shape over the fit, and the sign says which way it leans.
Level usually carries the bulk of a day. When slope jumps instead, the two ends pulled apart.
The components are estimated from a window of history and computed here, not published anywhere. Signs are pinned on purpose; left free they flip between fits and reverse every history.
