    Given the potentially severe financial consequences due to climate change, understanding how climate risks contribute to firms’ credit risk is essential. Building on a Merton-type model, we propose a new model that introduces a random growth adjustment factor in the firm value dynamics to reflect the depreciation due to climate risks. We also review the current state of the literature on how structural models of credit risk are employed to model the impact of climate risk on financial markets. Motivated by the theoretical models, we utilize the information contained in the spreads of Credit Default Swap (CDS) contracts to construct a market-implied, forward-looking carbon risk (CR) factor. We examine empirically how the scope and speed of economic transformation vary across jurisdictions, sectors, and over time. Explicit carbon emission pricing enables lenders to sharpen their assessments. The breadth of the regulation intensifies financial repercussions from carbon risk. The impact differs significantly across industries, indicating that the market identifies which sectors are better poised for a transition to a low-carbon economy. Lenders expect that adjustments in carbon regulations in Europe will cause relatively higher policy-related costs in the near future.

    This survey article reviews the current state of literature on how structural models of credit risk are employed to model the impact of climate risk on financial markets. We discuss how the two prominent types of climate risk, physical and transition risk, are captured by the seminal Merton model and its well-known extensions. Theoretical and practical advantages and drawbacks are worked out and an outlook on possible model improvements is provided.

    Using Credit Default Swap spreads, we construct a forward-looking, market-implied carbon risk factor and show that carbon risk affects firms’ credit spread. The effect is larger for European than North American firms and varies substantially across industries, suggesting the market recognises where and which sectors are better positioned for a transition to a low-carbon economy. Moreover, lenders demand more credit protection for those borrowers perceived to be more exposed to carbon risk when market-wide concern about climate change risk is elevated. Finally, lenders expect that adjustments in carbon regulations in Europe will cause relatively larger policy-related costs in the near future.

In: 16th International Conference on the European Energy Market (EEM) (2019), p. 1-6. doi:10.1109/EEM.2019.8916326Full textCitationDetails

    Existing research indicates that on the intraday market for power deliveries in Germany market orders tend to arrive in clusters. To capture such clustering, point processes with an intensity depending on past events, so-called Hawkes processes, appear to be promising. We consider the question whether there is a temporal structure prevalent in the parameters of Hawkes processes estimated for adjacent delivery hours. First we model a diurnal seasonality pattern found in the data and provide an economic intepretation for it. For the remaining decomposed series, we then propose simple (vector) autoregressive models to describe the serial structure. To evaluate our model we conduct a forecasting study. Testing against a benchmark model and a model without any serial structure, we find evidence for our proposed model. Our study reveals that capturing the serial structure in the parameters proves to be useful in understanding the underlying market microstructure.
