Sea Level Rise Exposure and Municipal Bond Yields
NBER 2022.11.30 원문보기
Municipal bond markets begin 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 is not solely driven by near-term flood risk. We use a structural model of credit risk to quantify the implied economic impact and distinguish the effects of underlying asset values and uncertainty. The SLR exposure premium exhibits a different trend from house prices and is unaffected by house price controls. Taken together, our results highlight the importance of climate uncertainty in driving municipal bond prices.
