Abstract/Summary

We compare the interaction between the crude oil and US stock markets in regimes where oil price uncertainty is high versus low, using a smooth transition vector autoregressive model. Our results show that supply- and demand-side shocks from the oil market, as well as stock market shocks, tend to have greater effect sizes in the lower oil price uncertainty regime. These asymmetric findings are consistent with the premise that shocks occurring in a relatively calmer environment are inclined to surprise market participants more, thereby eliciting amplified responses, than during an environment where oil price uncertainty is anticipated to be higher.
