Abstract

We find that climate-related risks forecast the intraday-data-based realized volatility of exchange-rate returns of eight major fossil fuel-exporters (Australia, Brazil, Canada, Malaysia, Mexico, Norway, Russia, and South Africa). We study a wide array of metrics capturing risks associated with climate change, derived from data directly on variables such as, for example, abnormal patterns of temperature. We control for various other moments (realized skewness, realized kurtosis, realized good and variance, upside and downside tail risk, and jumps) and estimate our forecasting models using random forests, a machine-learning technique tailored to analyze models with many predictors.
