In this paper, we investigate the effects of the firm-level climate change risk on the marginal value of corporate cash holdings. The underlying idea is that climate change risks would induce firms to increase their demand for capital, which may also lead to an increase in the value of the cash holdings. As the climate change risk is an uncertainty for firms, investors would also positively evaluate the firm’s excess cash. A regression analysis finds a positive association between the firm-level climate change risk and the value of cash holdings. Furthermore, we also test how the green swan and financial constraint level affect the relationship. Subsample analysis shows that the market positively values the cash holdings of firms that are more sensitive to climate change and that are more financially constrained. Various robustness tests confirm that the baseline regression results are not necessarily driven by endogeneity.
