This paper assesses the effects of US-China political tensions on the oil market. Relying on a quantitative measure of these relationships, we investigate how their dynamics impact oil demand, supply, and prices over various periods, starting from 1971 to 2019. To this end, we estimate a structural vector autoregressive model as well as local projections and show that political tensions between the two countries pull down oil demand and raise supply at medium- and long-run horizons. Overall, our findings show that conflicting relationships between these two major players in the oil market may have crucial impacts, such as the development of new strategic partnerships.
