The Russia-Ukraine war, which erupted early this year, has unleashed a cascade of challenges across the global economy, significantly disrupting financial markets.

As volatility spikes, investors and policymakers alike are grappling with the far-reaching effects of this conflict. Amidst this complex landscape, Nigerian economist Johnson Oliyide has emerged as a critical voice, providing nuanced analyses of how this geopolitical crisis is reshaping financial stability, commodity prices, and investment strategies.

In his current research, conducted in collaboration with esteemed economists Mr. Oluwasegun Adekoya, Professor Olaoluwa Yaya, and Dr. Mamdouh Al-Faryan, Oliyide examines the intricate connections between crude oil markets and other prominent financial assets during the Russia-Ukraine war.

Explaining the motivation behind this study, Oliyide states, “The Russia-Ukraine conflict is the most consequential in Europe since World War II, fundamentally altering the dynamics of the oil market and related sectors.

Given the historical ties between oil and various financial and commodity markets, our research seeks to determine how these relationships evolve under the stress of wartime volatility. Using intra-day data, we are pioneering an analysis of oil’s interaction with key financial assets—bonds, Bitcoin, the U.S. dollar, gold, and stocks—both before and during the war.”

The use of intra-day data—capturing financial transactions within a single trading day—enables the team to achieve a granular understanding of market responses to geopolitical shocks. This approach allows for a precise analysis of market dynamics, revealing how swiftly and significantly these markets react to the evolving crisis.

Sharing preliminary findings from their research, Oliyide notes, “Our study indicates that market connectedness intensifies during the war compared to pre-war periods.
Notably, oil has transitioned from being a net receiver of spillovers to a net transmitter during the conflict, underscoring its shifting role in the global market landscape.”

On the implications of these findings, Oliyide explains, “Investors must recognize that, much like other crises, wars amplify the interconnectedness of financial markets, especially in the early stages of the conflict. This heightened correlation suggests that diversification strategies may falter, leading to significant losses if these assets are combined during periods of extreme volatility.
Unlike in previous crises where oil prices typically decline, the current conflict has seen oil emerge as a safe-haven asset, primarily due to its role as a net transmitter of risks.”

However, Oliyide cautions that this phenomenon may not be universal. “It’s crucial to understand that the safe-haven property of oil observed in the Russia-Ukraine conflict may not apply in other types of wars. This conflict has triggered a supply shock, driving up oil prices, whereas wars causing demand shocks might produce entirely different market behaviors. Short-term investors should remain vigilant, as these spillover effects could prove temporary.”
