APAC Equities: The Sensitivity To Oil Prices

The traditional positive correlation between oil prices and APAC equity markets has largely decoupled since 2024, influenced by supply shocks, AI-driven rallies, and geopolitical shifts, necessitating nuanced analysis. Australia's equity market maintains the highest positive beta due to its significant energy and basic materials exposure, while India, Indonesia, and Thailand exhibit lower or negative sensitivities driven by domestic factors or import reliance. Notably, China's beta has recently increased. This divergence highlights that while Energy and Basic Materials sectors generally retain high oil betas, country- and industry-specific dynamics, such as Consumer Staples' inverse correlation, are now paramount for investors navigating volatile oil markets.

Analysis

The traditional positive correlation between oil prices and APAC equity markets has materially weakened since 2024, a decoupling driven by a confluence of factors including supply-side shocks, the AI-led equity rally which has disconnected stock performance from broad economic indicators, and idiosyncratic domestic politics. Country-level analysis reveals significant divergence. Australian equities exhibit the highest positive beta to oil, a direct result of the market's heavy composition in Basic Materials (15.8% vs. APAC average of 4.8%) and Energy (4.8% vs. 3.0%). In contrast, major oil importers like India show a low or even negative beta, as lower oil prices reduce corporate input costs and benefit its large oil-to-chemicals sector. Similarly, domestic political turmoil has suppressed investor sentiment and driven decoupling in Indonesia and Thailand, the latter of which saw its beta turn negative in Q3 2024. China is a notable exception, being the only market where the beta to oil has increased over the last three years, particularly since February 2025, as its equity market emerges from a prolonged, domestically-driven bear market. At the industry level, Energy and Basic Materials sectors predictably show the highest positive betas, while Consumer Staples exhibit negative correlations. Australian Utilities, including firms like AGL Energy and Origin Energy, are an important anomaly, displaying a higher beta than their regional peers due to their vertically-integrated models that have greater exposure to wholesale energy prices.

Key Decisions for Investors

• Investors should abandon the assumption of a monolithic APAC response to oil price movements and instead adopt a country- and sector-specific approach for portfolio construction and hedging.
• For a bullish view on oil, consider a relative value strategy by going long Australian equities, given their high positive beta, while shorting Indian equities, which tend to benefit from lower oil prices.
• To hedge against rising oil prices, overweighting sectors with negative betas like Consumer Staples or focusing on markets like India and Thailand, where domestic factors currently dominate equity performance, could prove effective.
• Exercise caution when using the Utilities sector as a defensive play against oil volatility, as Australian utilities like AGL and Origin are an exception, exhibiting a higher positive beta due to their integrated energy business models.
• Closely monitor China's rising beta to oil, as its post-bear market realignment could present new tactical trading opportunities or introduce previously uncorrelated risks to global macro strategies.
