Oil Price and Stock Prices Volatility Transmission in Nigeria

Abstract

The study investigates the relationship among oil price (OP), oil price volatility (OPV) and stock price volatility (SPV) in Nigeria, using an Autoregressive Distributed Lag (ARDL) model, Toda-Yamamoto-Dolado-Lutkepohl (TYDL) test, and Breitung-Candelon Frequency Domain Causality Test. The study shows that OP causes the SPV and OPV in a one-way direction in the long run. However, there was evidence of bi-directional relationship with SPV in the medium-run. It also shows that the OPV and SPV positively impact OP in the short and long run. Overall, the study found that there is a greater tendency that oil price adjusts back to its long-run equilibrium when affected by stock market prices. Therefore, it recommends that policymakers consider the movement in oil price and stock price in shaping the capital market's operation and ensuring the proceeds from increased oil prices are utilised maximally for economic revitalisation in Nigeria.
