The first quarter of 2026 will be remembered as one of the most consequential periods in decades. A war erupted in the Middle East, the Strait of Hormuz closed, oil prices surged past US$100 per barrel, and inflation roared back to life. For our Newcastle clients and Australian households across the country, this has meant two consecutive interest rate hikes and a stark reminder that the cost-of-living battle is far from over.
Geopolitical Crisis: The Iran War and Global Oil Shock
On February 28th, 2026, the United States and Israel launched Operation Epic Fury, coordinated airstrikes on Iran that resulted in the death of Supreme Leader Ali Khamenei. Iran responded with missile barrages on Israeli cities and US bases across the Gulf, escalating into full-scale military conflict.
The Immediate Economic Impact
The most severe economic consequence came from Iran’s closure of the Strait of Hormuz, through which roughly 20% of global oil supply normally transits. Shipping traffic dropped to near zero, forcing Gulf producers including Iraq and Kuwait to curtail production.
Oil prices surged from around US$60 per barrel to peak at US$126 in mid-March, the fastest spike since the 1970s. This has resulted in fuel prices surging across Australia, particularly diesel costs, which are a key driver of broader inflation throughout the economy.
Government Response Measures
Global governments coordinated a record 400 million barrel release from strategic petroleum reserves. Australia cut half of the government fuel excise for three months, and the US temporarily lifted sanctions on Russian and Iranian oil to ease supply pressures.
Despite these emergency measures, energy analysts warn that unless the strait reopens by mid-April, the disruption could become the largest in global oil market history, with potentially severe consequences for the global economy.
Interest Rates: Back-to-Back Hikes Shock Borrowers
The Reserve Bank of Australia raised the cash rate twice in quick succession, from 3.60% to 3.85% in February, then to 4.10% in March. This represents a dramatic reversal from the rate-cutting cycle we experienced throughout 2025.
February’s Unanimous Decision
The February increase was unanimous among board members, driven by inflation data showing price pressures had picked up materially in the second half of 2025. The RBA made clear that bringing inflation back to the target range remained their priority.
March’s Split Decision
The March hike came in a split 5-4 decision, with the board acknowledging the Iran conflict added significant upside risk to inflation through higher energy costs. RBA Governor Michele Bullock emphasised the board’s commitment to getting inflation back to target, even if that means economic pain in the near term.
What This Means for Mortgage Holders
For those with home loans, the twin hikes have already added roughly $150 per month to repayments on a $500,000 loan, squeezing household budgets considerably. Markets now expect at least one more increase at the May meeting, which would bring the cash rate to 4.35%, matching the previous cycle’s peak. Some banks are even predicting a second rise later in the year.
If you’re concerned about how further rate rises might affect your cash flow and financial planning, now is an excellent time to schedule a review with our Newcastle team.
Inflation: Stubborn and Broadening
Inflation moderated slightly to 3.7% in February from 3.8% in January, but remained stubbornly above the RBA’s 2-3% target range. Trimmed mean inflation, the RBA’s preferred measure, held at 3.3%, unchanged from January.
Key Inflation Drivers
Housing costs drove much of the increase, rising 7.2% annually. Electricity prices surged 37% as government rebates expired, a painful hit for household budgets. Food inflation remained elevated at 3.1%, with beef and lamb prices up 13%.
Prior to the Iran war, automotive fuel prices had been falling, down 7.2% year-on-year by February, providing some relief. However, that trend reversed sharply in March as oil prices spiked.
Rising Inflation Expectations
Perhaps most concerning, inflation expectations jumped significantly. The ANZ-Roy Morgan measure surged from 5.3% in February to 6.9% in mid-March, the highest on record, reflecting household concerns about energy-driven price pressures flowing through to everyday costs.
Oil Prices: From Relief to Crisis
The quarter began with oil prices providing welcome relief. Brent crude traded in the US$57-60 range through January and early February as global markets remained oversupplied. Australian petrol prices averaged around $1.80 per litre, down from $1.87 in September, easing cost-of-living pressures.
The Dramatic Reversal
That changed dramatically after February 28th. Within days, Brent crude jumped above US$80, then surged past US$100 on March 8th for the first time in four years. Prices peaked at US$126 mid-quarter before settling around US$103-110 as strategic reserve releases took effect.
Australian petrol prices followed suit, climbing sharply through March and threatening to push inflation significantly higher in the months ahead.
Cost of Living: A Perfect Storm
The combination of higher interest rates, elevated inflation, and surging energy costs created a perfect storm for household budgets during the quarter.
The February rate hike alone added $75 monthly to a typical $500,000 mortgage, with March’s increase adding another $75 on top. Electricity costs continued climbing as rebates expired, while food prices remained stubbornly high. The brief reprieve from falling fuel prices early in the quarter quickly evaporated.
Consumer confidence, which had surged in late 2025, began softening as households absorbed the reality of a higher-for-longer interest rate environment.
Investment Markets: Cautious Amid Volatility
The ASX 200 started the year at 8,714 points and traded in a relatively narrow range throughout the quarter despite global volatility.
Sector Performance
The index benefited from strong materials sector performance as commodity prices held firm, with gold remaining near US$5,300 per ounce, providing valuable support for Australian resource companies.
However, the financials sector, which represents one-third of the index, faced headwinds as investors worried about higher rates potentially impacting mortgage arrears and credit quality.
Healthcare and information technology sectors struggled, as fears of an AI-stock bubble caused a sell-off across the IT sector, causing both indexes to trade lower for the quarter.
Overall, the ASX 200 remained range-bound between 8,400 and 9,200 points, reflecting investor caution about the unfolding geopolitical crisis and domestic inflation outlook.
What This Means for Your Financial Planning
As we move into the second quarter, several key considerations should inform your financial planning strategy:
Interest Rate Management: With at least one more rate rise likely in May, ensuring your budget can accommodate higher mortgage repayments is critical. If you’re experiencing cash flow pressure, there may be strategies we can discuss to help manage this challenge.
Inflation Protection: With inflation proving more persistent than expected and energy costs rising, consider whether your portfolio includes appropriate inflation-hedging strategies. Assets with pricing power become increasingly valuable in this environment.
Quality Focus: In uncertain times, investments with strong fundamentals, consistent cash flows, and proven management teams tend to outperform. This is not the time for speculative positions.
Energy Exposure: The geopolitical situation highlights both risks and opportunities in the energy sector. Appropriate positioning requires careful consideration of your risk tolerance and time horizon.
Portfolio Resilience: Diversification across asset classes and geographies remains essential. The events of Q1 2026 demonstrate how quickly global developments can impact Australian investors.
Looking Ahead: Navigating Extraordinary Uncertainty
The second quarter begins with extraordinary uncertainty. The duration and ultimate resolution of the Iran conflict will largely determine whether oil prices stabilise or spike higher.
The Critical Timeline
If the Strait of Hormuz remains closed past mid-April, energy analysts warn of potential diesel shortages and prices reaching US$170-200 per barrel, a scenario that would trigger a global stagflationary shock. The only way out of such a situation would be to forcibly trigger an economic recession through aggressive monetary policy tightening.
Australia’s Near-Term Challenges
For Australia, the path ahead is challenging. Another rate rise at the May RBA meeting appears likely unless inflation data shows dramatic improvement. Household budgets will remain stretched as energy and food costs stay elevated.
The labour market remains relatively resilient, but cracks are emerging as higher rates and cost pressures flow through to employment conditions.
Investment Principles for Turbulent Times
For investors, the fundamental principles remain unchanged:
- Maintain appropriate diversification across asset classes and geographies
- Focus on quality assets with pricing power and strong balance sheets
- Avoid panic-driven decisions based on headlines
- Keep adequate cash reserves for both opportunities and peace of mind
- Regular portfolio reviews to ensure alignment with long-term goals
While the first quarter of 2026 brought significant challenges, economies and markets have weathered similar shocks before. The path forward requires patience, prudent risk management, and an eye toward long-term fundamentals rather than short-term headlines.
