Beyond the barrel: How oil price shocks reshape Nigeria's fiscal landscape-a multi-dimensional analysis

Nigeria's fiscal destiny remains tethered to the volatile rhythms of global oil markets, yet the mechanisms through which price shocks translate into policy responses are far more intricate than conventional resource curse narratives suggest. This study examines the impact of oil price shocks on fiscal policy responses in Nigeria from 1986 to 2023, integrating five critical control variable categories: demographic factors, macroeconomic conditions, institutional quality, global financial dynamics, and infrastructural capacity. Unlike previous studies that treat fiscal procyclicality as a uniform dysfunction, we disentangle how these conditioning variables moderate the oil-fiscal transmission mechanism. Employing a structural vector autoregression framework with asymmetric shock identification, we find that institutional quality serves as the primary moderator—improving governance reduces procyclical expenditure bias by 34%—while demographic pressures constrain discretionary policy space regardless of oil market conditions. The analysis reveals a troubling asymmetry: positive oil shocks trigger immediate spending expansion, but negative shocks fail to induce commensurate consolidation, generating a ratchet effect that elevates debt vulnerability. Global financial conditions, particularly US monetary policy, exert independent influence on fiscal capacity, complicating domestic stabilization efforts. These findings challenge the presumption that oil dependence alone dictates fiscal outcomes, demonstrating instead that institutional resilience and demographic management determine whether resource wealth becomes a blessing or curse. For policymakers, the message is clear: without addressing the structural scaffolding of governance, demographics, and global integration, stabilization mechanisms like sovereign wealth funds remain cosmetic rather than curative.
