''Deconstructing oil price surprises around OPEC announcements''
( 2026, Vol. 0 No.0 )
 
 
This paper revisits the identification of oil price shocks using high-frequency surprises around OPEC announcements. While previous studies have used changes in oil futures prices to proxy for supply shocks, recent evidence suggests that these surprises reflect a combination of demand factors. To address this identification challenge, I use a Bayesian structural vector autoregression (VAR) model and identify oil supply, inventory demand, and aggregate demand shocks by imposing sign-restrictions on high-frequency surprises in oil futures, the S&P 500, and the one-year U.S. bond yield. My analysis highlights that the response of bond yields to OPEC announcements may contain important information about the source of the oil shock.
