Most Australians think about petrol prices as a weekly annoyance. But what is happening beneath the surface is far more important, especially for investors.
At Nucleus Wealth, we’ve been analysing how oil prices, fuel security and electric vehicles are interacting. The conclusion is simple: Australia is unusually exposed to what comes next.
Australia is a price taker in a riskier world. Global oil prices are increasingly driven by geopolitics rather than just supply and demand. Conflicts in the Middle East, disruptions in Russia and risks around key shipping routes all feed directly into prices at the bowser. Australia has very little insulation from this. We import most of our refined fuel and have limited domestic capacity. When global prices move, Australian consumers feel it almost immediately.
Diesel is the real inflation story. Petrol gets the headlines, but diesel matters more. It powers freight, agriculture, mining, and supply chains. When diesel prices rise, the impact flows through to food prices, transport costs, and broader inflation. This is one reason inflation has proven more persistent than many expected.
Fuel security is no longer theoretical. A decade ago, Australia had around twelve refineries. Today, it has two. That shift made economic sense in a globalised world, but in a more fragmented geopolitical environment it creates risk. If supply chains are disrupted, the issue is not just price but availability.
Higher oil prices are accelerating EV economics. There is a paradox in energy markets. Higher oil prices hurt in the short term, but they make alternatives such as electric vehicles more attractive. Globally, this is accelerating the transition, but Australia is different.
Australia’s EV transition will be slower. Passenger vehicles will electrify over time, but the real constraint is heavy transport. Electric trucks are not yet widely viable at scale, particularly for long-distance freight. They face challenges around range and infrastructure, and these sectors are critical for food and goods distribution. As a result, Australia will remain structurally dependent on diesel for longer than many expect.
What this means for investors is a more complex backdrop. In the short term, there is energy price volatility and ongoing inflation pressure. In the medium term, there is an increased focus on energy security and policy uncertainty. In the long term, there will be gradual electrification, but uneven across sectors.
This is not just an energy story. It is a macro story that feeds into inflation, interest rates, asset prices, and ultimately portfolio construction. It reinforces a key principle: the future is uncertain, and portfolios need to be built for multiple scenarios.
At Nucleus Wealth, that is exactly how we invest. If you are thinking about how these structural shifts impact your portfolio, you can explore how we position portfolios for this type of environment in our portfolio & performance pages.
