The Macroeconomics of Strategic Petroleum Reserve

The existing literature insufficiently addresses how Strategic Petroleum Reserves (SPR) policy should be adjusted to ensure energy security in a macroeconomic context. This paper focuses on the implications of SPR policies within such stochastic environments. Using an occasionally binding constraint Dynamic Stochastic General Equilibrium (DSGE) model, we uncover how SPR influences economic stability amidst international oil price shocks and domestic demand uncertainties. Our findings suggest that optimal SPR policies share similarities with traditional fiscal policies in their ability to mitigate the negative economic impacts of oil price shocks by stimulating domestic oil demand. Furthermore, we find that optimal SPR policies are heavily influenced by two key factors: the government’s access to accurate information about domestic oil demand and its objective in addressing oil crises. Specifically, the extent to which the government wants to prevent the oil crisis from occurring, as well as its willingness to stabilize domestic oil prices, plays a crucial role in determining the effectiveness of SPR policies. • The macroeconomic effect of Strategic Petroleum Reserve (SPR) is studied. • An occasionally binding constraint DSGE approach is used to model the effects. • SPR policies can be used to stimulate aggregate demand against oil shocks. • Information accuracy on oil demand has significant impacts on the optimal SPR policy. • The effectiveness of SPR policy is affected by the government objectives functions.
