Commonwealth Bank analysts warn that the buffer for global oil supplies is ending, while China remains uniquely positioned to navigate the energy shock.

Commonwealth Bank’s Head of FX, International and Geopolitics, Joe Capurso, warns that the global reprieve from oil supply disruptions is rapidly concluding as the impact of the conflict in the Strait of Hormuz intensifies [3]. While some markets initially relied on existing cargo deliveries to maintain stability, Capurso notes that the period of buffer is ending, leading to significant pressure on global energy and food costs [3].

**Key takeaways**
* Commonwealth Bank warns that the five-to-six-week buffer for global oil supplies has ended, with infrastructure damage preventing a quick return to full export capacity [3].
* Higher energy costs are impacting industries like agriculture, where fertilizer and fuel prices have roughly doubled, likely leading to higher grocery store prices for households [3].
* China is considered better positioned than most nations due to its large commodity reserves and its status as a dominant producer of renewable energy technologies [3].
* Despite rhetoric regarding a blockade in the Strait of Hormuz, some data suggests that tanker traffic has quietly recovered to approximately 28 ships per day, with Chinese vessels successfully transiting the area [1].

## The divergence in global energy impacts
The economic consequences of the current oil shock are being distributed unevenly across the globe. According to Capurso, energy-exporting nations like Canada may benefit from the rise in prices, while energy-importing regions such as Europe and Japan face the dual challenge of paying higher costs and potentially receiving lower volumes of fuel [3]. This volatility extends into the agricultural sector, where farmers are facing a squeeze from both increased fuel expenses and the rising cost of gas-derived fertilizers [3].

While the broader global outlook remains strained, China appears to be an outlier in its ability to manage the disruption [3]. Beyond its significant stockpiles of oil and other commodities, China’s leadership in the production of renewable technologies—including solar panels, wind turbines, and electric vehicles—positions the country to potentially benefit as the oil shock accelerates global decarbonization efforts [3].

## Geopolitical tensions and shipping realities
The geopolitical landscape surrounding the conflict remains complex, with varying interpretations of the situation on the ground. While some observers express skepticism regarding the potential for a lasting peace deal, others suggest that the primary goal of leadership in nations like China, Russia, and Iran is to maintain power and stability, which may create room for negotiation [1]. 

Discrepancies also exist between public rhetoric and shipping data. Although there have been reports of an oil blockade, tanker transits through the Strait of Hormuz have seen a recovery from a low of 2% of normal traffic to roughly 28 ships per day [1]. Reports indicate that Chinese vessels, in particular, have been able to continue their transits despite the heightened tensions [1].

## Why it matters
The end of the global supply buffer signals a transition into a more difficult phase for international markets, where the physical damage to energy infrastructure will likely prevent a rapid return to normalcy [3]. As costs for essential inputs like fuel and fertilizer continue to rise, the inflationary pressure on food and consumer goods is expected to become more pronounced for households [3]. Looking ahead, the conflict may serve as a catalyst for a faster shift toward renewable energy, a transition in which China is already heavily invested as a primary manufacturer of green technology [3].
