A bear steepener occurs when long-end yields rise sharply while short-end yields rise modestly or hold — the curve gets steeper primarily from the long end selling off. Historically signals any of: reflation expectations, fiscal concerns, or supply pressures. **Reflation / growth repricing.** The most common bear steepener narrative: markets forecast stronger growth and higher inflation ahead. Long-end rates incorporate these expectations via higher term premia and implied forward rates. Short rates rise less because the Fed's near-term path is already priced. Examples: 2020-2021 vaccine rollout, 2016 Trump election, periodic growth surprises. **Fiscal supply.** When Treasury issues large amounts of long-duration debt (deficit financing, infrastructure bills), auction absorption pushes long yields up. Short rates remain anchored by Fed policy. The 2023 August US debt downgrade episode featured a prominent bear steepener. **Term premium reset.** Long-dormant term premia can re-emerge when uncertainty about inflation, Fed credibility, or fiscal sustainability rises. This pushes long yields higher without corresponding short-rate moves. Equity market reactions: typically negative for long-duration growth stocks (tech, biotech) because discount rates rise. Banks often benefit from wider NIMs. Cyclicals outperform defensives if the steepening reflects growth optimism. ```mermaid flowchart TD A[Bear Steepener] --> B[Growth Optimism] A --> C[Supply Pressure] A --> D[Term Premium] B --> E[Risk-On
