Why the Curve Slopes — Term Premium and Expectations
The expectations hypothesis
In its purest form: the 10-year yield should equal the average of expected 1-year rates over the next decade. Under that view, an inverted curve is the market literally forecasting rate cuts — which historically accompanies recession expectations. The hypothesis explains a lot of curve behavior, and fails cleanly in one specific way: it implies the term premium (the extra yield for locking money up longer) is zero, and it persistently is not.
The term premium
Lenders demand compensation for duration risk — the possibility that inflation or rates surprise upward while your money is locked. That compensation, the term premium, is unobservable and estimated by models (ACM, Kim-Wright); it has trended down for decades (QE, global savings, inflation credibility all proposed as causes), turning negative in the 2010s. When the premium is low, curves flatten without any recession forecast — which is exactly why modern curve signals need more care than the textbook story suggests.
Who owns which part
The front of the curve (1M–1Y) is essentially the Fed's policy rate and its immediate path. The long end is a global market's judgment: growth, inflation, premium. The belly (2–5Y) is the battleground where the two negotiate. This is why the panel shows the whole curve shape, not just one spread: the shape tells you who is driving. A bear-flattening (long end rising to meet a fixed front) means something very different from a bull-inversion (front end collapsing on cuts).
10Y yield ≈ avg expected short rates + term premium
Yield decomposition — Inversion = expected cuts, low premium, or both — disentangling them is the analyst's job.
2013: the taper tantrum, a premium event
May 2013: Bernanke mentioned "tapering" bond purchases; 10-year yields jumped ~100bp in months while the Fed moved its policy rate zero. Nothing about expected short rates justified the move — it was a term-premium repricing. Growth stocks and rate-sensitive sectors de-rated sharply. Lesson: the long end can move for premium reasons that have nothing to do with the economy's path, which is why single-spread readings need the whole-curve context the panel provides.
