What are the main yield curve positioning strategies, and how do managers profit from anticipated curve shape changes?

Yield curve positioning strategies involve taking duration-neutral positions that profit from changes in the shape of the yield curve rather than its overall level. The four main scenarios combine direction (bull/bear) with shape (steepener/flattener).\n\nThe Four Curve Scenarios:\n\n| Scenario | Short Rates | Long Rates | Spread | Typical Driver |\n|---|---|---|---|---|\n| Bull Steepener | Fall a lot | Fall a little | Widens | Fed easing cycle begins |\n| Bear Steepener | Rise a little | Rise a lot | Widens | Fiscal expansion, inflation fears |\n| Bull Flattener | Fall a little | Fall a lot | Narrows | Flight to quality, recession |\n| Bear Flattener | Rise a lot | Rise a little | Narrows | Fed tightening cycle |\n\n`mermaid\ngraph TD\n A{\"Rate Direction?\"} -->|\"Rates Falling

Short rates will fall 100 bps while long rates fall only 30 bps.\n\nPortfolio construction (duration-neutral):\n- Long $50M of 2-year Treasuries (duration = 1.95y, BPV = $9,750)\n- Short $50M x (9,750 / 48,500) of 30-year Treasuries -> short ~$10.05M (duration = 21.5y, BPV matched at $9,750)\n\nP&L if the view is correct:\n- 2-year gain: $9,750 x 100 = +$975,000\n- 30-year loss: $9,750 x 30 = -$292,500 (short position gains from smaller rate decline)\n- Wait: since we are short the 30-year and rates fall, we lose: -$9,750 x 30 = -$292,500\n- Net profit: $975,000 - $292,500 = +$682,500\n\nDuration-Neutrality is Key:\nEach strategy must be structured so the portfolio is insensitive to a parallel shift. Profit comes only from the curve changing shape. This is achieved by matching the BPV (dollar duration) of the long and short legs.\n\nPractical Considerations:\n- Carry and rolldown may favor or penalize the position while waiting for the view to materialize\n- Butterfly trades add a middle leg for more precision (e.g., 2s-10s-30s)\n- Swap curve vs Treasury curve positioning can exploit different dynamics\n\nTest your curve strategy skills in our CFA Fixed Income question bank.
