### Overview and research question
- Introduces time-varying systemic risk in an otherwise standard New-Keynesian model.
- Objective: study whether a simple leaning-against-the-wind policy can reduce systemic risk and improve welfare.

### Key findings
- An unexpected increase in policy rates:
  - reduces output,
  - reduces inflation,
  - reduces asset prices,
  - does not fundamentally mitigate financial risks.
- A systematic monetary policy reaction:
  - can improve welfare,
  - is highly sensitive to parameters of the model,
  - is detrimental in the presence of falling asset prices.
- Macroprudential policy, similar to a countercyclical capital requirement:
  - is more robust,
  - leads to higher welfare gains.

### Policy implications and recommendations
- Leaning-against-the-wind monetary tightening is ineffective at fundamentally mitigating systemic financial risks and can harm macroeconomic outcomes.
- Systematic monetary-policy rules are insufficient alone due to parameter sensitivity and adverse effects when asset prices fall.
- Macroprudential tools (for example, countercyclical capital requirements) are preferred for robustness and greater welfare improvement.
