The study, published in the Journal of the Operational Research Society, and led by Dr Chrysovalantis Vasilakis from Bangor University, found the new method “improved accuracy significantly, especially during turbulent times”.
The paper is published amid considerable spikes in oil prices, volatility, and global economic turbulence driven by geopolitical conflicts and supply disruptions.
Though crude oil prices play a central role in economic stability, energy security, and business planning, they can be notoriously difficult to predict especially during periods of global financial stress. The study shows that oil price forecasts can be substantially improved by monitoring a simple measure of global financial integration, which captures how closely international stock markets move together.
Researchers, including at Dr Cindy Wang, Associate Professor of Economics at Peking University in China, did this by introducing a new “global risk” indicator that reflects rising synchronisation across major stock markets, a pattern that typically emerges during global shocks such as financial crises, geopolitical conflicts, or pandemics. When this “global risk” measure was added to standard forecasting models, predictions of monthly oil price movements become more accurate and more stable, particularly during volatile periods.
Dr Chrysovalantis Vasilakis, Associate Professor in Economics at The Albert Gubay Business School at Bangor University said, “Predicting oil prices is notoriously difficult, but this research found a surprisingly simple way to do it better. Instead of complex models, just watch how closely stock markets around the world move together. When they suddenly synchronise, such as during financial crises, wars, or pandemics, oil prices tend to follow. Therefore, adding this single ‘global risk’ measure to basic forecasting tools improved accuracy significantly, especially during turbulent times. The best method correctly predicted the direction of monthly oil price changes 62% of the time – significantly better than the historical average of about 50%.”
“For anyone following energy markets, such as investors, business owners, or even households worried about fuel costs, this means more reliable clues about where prices are heading. The necessary data is available from public sources (FRED, academic websites) and standard financial data platforms such as Bloomberg. The key takeaway is in a connected global economy, watching only supply and demand misses the bigger picture. Keeping an eye on worldwide financial jitters can give you a real edge in anticipating oil price swings.”
Dr Chrysovalantis added, “Crucially, the study demonstrates that models that include the global risk factor are better at predicting the direction of oil price changes, which is often more important than forecasting the exact price level. For policy makers, the findings highlight that oil price dynamics are not driven solely by supply and demand fundamentals. Global financial conditions transmit quickly into commodity markets, implying that financial stress abroad can affect domestic energy prices. Monitoring global market integration can therefore support better macroeconomic forecasting, energy policy design, and crisis preparedness.”
Overall, the study argues that a single, transparent global risk measure, constructed from publicly available data, can meaningfully enhance oil market decision-making in an increasingly interconnected world.
