Sea-Level Rise Exposure and Municipal Bond Yields
研究发现，自2013年起，市政债券市场开始为海平面上升暴露风险定价，该效应在长期债券中更显著，且主要由气候不确定性驱动，而非短期洪水风险。
Abstract Municipal bond markets began pricing sea-level rise (SLR) exposure risk in 2013, coinciding with upward revisions to worst-case SLR projections and accompanying uncertainty around these projections. The effect is larger for long-maturity bonds and not solely driven by near-term flood risk. We use a structural model of credit risk to quantify the implied economic impact and distinguish between the effects of underlying asset values and of uncertainty. The SLR exposure premium exhibits a trend different from house prices and is unaffected by house price controls. Together, our results highlight the importance of climate uncertainty in driving municipal bond prices.
