Olivia ThompsonBrent crude oil surged to over USD $115 per barrel in April 2026 — a multi-year high driven by geopolitical disruptions to key global shipping routes. The spike, reported extensively by the Australian Financial Review, sent shockwaves through ASX-listed energy stocks, pushed petrol prices higher at Australian forecourts, and forced investors to reassess portfolios built around assumptions of stable commodity markets.
What Drove the Surge to $115
The immediate trigger was a series of disruptions to shipping routes that carry a significant portion of the world's oil supply. Geopolitical tensions in key transit corridors forced tanker diversions, adding transit time and cost, and temporarily constraining supply relative to demand.
This is not the first time Australia has experienced oil price volatility driven by geopolitical risk — the 1973 OPEC embargo, the Gulf War price spike of 1990, and the 2022 Russia-Ukraine driven energy crisis all left their mark on Australian household budgets and investment portfolios. Each time, the pattern was similar: sharp price rise, market dislocation, then gradual normalisation as supply chains adapted.
Whether the current spike follows the same trajectory depends on factors that are genuinely uncertain — the duration of shipping disruptions, OPEC production decisions, and global demand trajectory. What is certain is that Australian investors and households are already feeling the effects.
The Australian Impact: Petrol, Power, and Portfolios
Oil price spikes flow through the Australian economy via three primary channels:
Petrol prices at the pump. Australia imports approximately 90% of its liquid fuels, making domestic petrol prices highly sensitive to international crude benchmarks. A sustained $115/barrel Brent price typically translates to petrol prices in the $2.20-$2.50 per litre range nationally, depending on the Australian dollar exchange rate and refinery margins. As of April 2026, average metropolitan petrol prices have already risen materially from their 2025 lows.
Electricity costs. While Australia's electricity grid has diversified significantly toward renewables, natural gas remains a significant input to peak demand electricity generation in most states. Higher oil prices tend to push gas prices higher as a correlated commodity, which flows through to electricity spot prices and, with a lag, to consumer power bills.
Superannuation and investment portfolios. The ASX is home to major integrated energy companies with significant exposure to oil prices. A sustained high oil price environment can boost energy sector earnings — but it simultaneously increases inflationary pressure, which constrains central bank policy options and can dampen equity valuations in rate-sensitive sectors like property and technology.
What Financial Advisers Say About Commodity Price Shocks
For Australians with investment portfolios — including those holding superannuation outside the default balanced fund option — an oil price spike of this magnitude is worth reviewing with a financial adviser.
The core question is not whether oil is at $115 today, but what your portfolio's existing exposure to energy volatility looks like, and whether that exposure reflects your actual risk tolerance and investment timeline.
Key considerations that financial advisers typically explore during commodity price volatility:
Superannuation asset allocation. Many Australians in balanced or growth super funds have indirect exposure to energy commodities through ASX-listed stocks and global equity allocations. This exposure works in both directions: it can boost returns during price spikes, but also increases portfolio sensitivity to commodity cycles.
Inflation hedging. Oil price inflation is a primary driver of headline CPI. Australian households feeling the pinch at the petrol pump or on power bills are also experiencing real portfolio erosion if their investments don't keep pace with inflation. A financial adviser can model the real (inflation-adjusted) return implications of current allocations.
Currency effects. Australia is a commodity-exporting nation with a commodity-sensitive currency. When oil prices surge, the Australian dollar often strengthens against major currencies — which has mixed implications for internationally diversified portfolios.
According to the Australian Securities and Investments Commission's MoneySmart resource, understanding your personal risk profile and ensuring your investments align with your goals and timeline is the foundation of sound financial planning — particularly during periods of market volatility.
The RBA's Position and Interest Rate Implications
The Reserve Bank of Australia is monitoring the inflationary implications of sustained high oil prices closely. A prolonged period of energy-driven inflation could complicate the RBA's rate-setting calculus — slowing the pace of rate reductions that many Australian mortgage holders have been anticipating.
For Australians with variable rate mortgages or planning to refinance, this is relevant context. Financial advisers and mortgage brokers can model the household budget implications of different rate scenarios.
When to Review Your Position
Not every market event requires action. Long-term investors are generally better served by staying the course through commodity volatility than by reactive portfolio changes. But there are specific circumstances where a review with a financial adviser is warranted:
- You're within five years of retirement and your portfolio remains heavily weighted toward growth assets
- Your energy cost exposure (petrol, power) is significantly impacting household cashflow
- You're considering significant property or investment decisions that depend on interest rate assumptions
- You haven't reviewed your superannuation fund's asset allocation in more than two years
An oil price spike to $115 per barrel is a useful prompt to review — not panic. The decisions made calmly during market events tend to produce better long-term outcomes than those made reactively.
