Summary:
We explore the stock market and option implied volatility response of the oil and gas industry to four policy events associated with the Paris Agreement and the election of Donald Trump. Our results show that the signing of the Paris Agreement had a large negative impact for the Oil and Gas sector (CAAR -8.4%), with Exploration and Production (CAAR -12.2%) and Drilling (CAAR -10.5%) most severely affected. This is further supported by an increase in implied volatility and by a structural break in option trader sentiment around the signing of the agreement. In general, the Paris Agreement had a much stronger impact on firms that had primarily U.S.-focused operations. Contrary to expectations, the election of Donald Trump and the announced withdrawal of the U.S. from the Paris Agreement negatively affected some sub-sectors (transport and integrated) and the sector overall. We attribute this to (1) Trump’s policies supporting domestic production (benefitting unlisted independent producers at the expense of listed competitors with import and international assets), and (2) on “We Are Still In” efforts by U.S. states, cities and companies to continue to meet Paris Agreement goals. Overall, our results indicated that investors are pricing current policies when examining climate risk and that, in this respect, the Paris agreement trumped Trump.
