Background of the Study
Global oil price shocks have long been recognized as critical determinants of economic stability in oil-dependent economies. In Nigeria, where oil revenue forms the backbone of national income, fluctuations in global oil prices exert significant influence on economic performance. Sudden shifts in oil prices can trigger a cascade of effects—ranging from currency depreciation to fiscal imbalances—that impact macroeconomic indicators such as GDP growth, inflation, and employment (Ojo, 2023).
During periods of high oil prices, Nigeria experiences increased government revenues and improved fiscal balances, which can spur investments in infrastructure and social services. Conversely, a sharp decline in oil prices often results in fiscal crises characterized by reduced public spending, increased borrowing, and heightened social unrest. The volatility inherent in global oil markets thus poses a constant challenge to maintaining economic stability in Nigeria (Adegbola, 2024).
The dynamics of oil price shocks extend beyond immediate revenue losses; they affect exchange rate stability, investment flows, and consumer confidence. Policymakers in Nigeria have attempted to mitigate these adverse effects through the establishment of stabilization funds and fiscal diversification strategies. However, the effectiveness of these measures is often limited by the persistent structural dependency on oil revenue and the inherent volatility of international oil markets (Ibrahim, 2025).
This study examines the multifaceted impact of global oil price shocks on Nigeria’s economic stability. By integrating theoretical models with empirical data, the research investigates the transmission mechanisms through which oil price fluctuations influence key economic indicators. It also evaluates the efficacy of policy interventions designed to cushion the economy against these shocks. The ultimate goal is to provide policymakers with evidence-based recommendations for enhancing economic resilience and ensuring sustainable development in the face of ongoing oil market volatility (Ojo, 2023).
Statement of the Problem
Despite Nigeria’s substantial oil reserves, the economy remains highly vulnerable to global oil price shocks, which pose persistent challenges to economic stability. Fluctuations in oil prices result in unpredictable government revenues, causing fiscal imbalances that disrupt long-term economic planning. Periods of declining oil prices have led to severe budgetary constraints, forcing the government to rely on increased borrowing and short-term fiscal measures that may undermine sustainable growth (Ojo, 2023).
The reliance on oil revenue creates structural vulnerabilities, making it difficult to implement effective countercyclical policies during downturns. This dependency exacerbates the impact of oil price shocks on exchange rate volatility, inflation, and public investment, thereby hampering overall economic stability. Furthermore, policy responses to oil price shocks have often been reactive rather than proactive, with measures that fail to address the underlying structural issues in the economy (Adegbola, 2024).
Another significant challenge is the limited diversification of the economy. Nigeria’s heavy reliance on oil revenue means that external shocks have a disproportionate impact, reducing the country’s capacity to maintain stable economic performance. The inadequacy of alternative revenue sources further intensifies the adverse effects of oil price declines. This study seeks to address these challenges by analyzing the direct and indirect effects of global oil price shocks on Nigeria’s economic stability, identifying the mechanisms that transmit these shocks, and evaluating the effectiveness of existing policy measures (Ibrahim, 2025).
Objectives of the Study
1. To evaluate the impact of global oil price shocks on Nigeria’s key economic indicators.
2. To analyze the effectiveness of policy measures in mitigating the adverse effects of oil price fluctuations.
3. To propose strategies for enhancing economic resilience in the face of oil price volatility.
Research Questions
1. How do global oil price shocks affect Nigeria’s fiscal and economic stability?
2. What are the transmission mechanisms through which oil price fluctuations impact the Nigerian economy?
3. What policy interventions can mitigate the negative effects of oil price shocks on economic stability?
Research Hypotheses
1. Global oil price shocks significantly disrupt Nigeria’s economic stability.
2. Effective policy measures can mitigate the adverse effects of oil price fluctuations.
3. Diversification of revenue sources reduces the vulnerability of Nigeria’s economy to oil price shocks.
Scope and Limitations of the Study
This study examines the impact of global oil price shocks on Nigeria’s economic stability, focusing on fiscal and macroeconomic indicators over recent decades. Limitations include data reliability and the challenge of isolating oil price effects from other external factors.
