Yield curve regimes classify the interest rate environment into four states based on the direction of the level (1 Yr yield) and slope (1 Yr − 2 Mo spread). A Bull Steep regime occurs when yields are falling and the curve is steepening — typical of Fed easing cycles. A Bear Flat regime means yields are rising while the curve flattens, often seen during monetary tightening. Bull Flat reflects falling yields with a flattening curve (flight-to-quality rally concentrated in long maturities), and Bear Steep indicates rising yields with a steepening curve (term premium expansion or fiscal concern). The current regime of Bull Steep with a spread of -9 bps provides context for positioning decisions — each regime historically favors different duration and curve strategies.
