Iran War Australian Property: 50 Years of Data Exposed — APS
Last Updated: 2026-03-10
TL;DR — Key Takeaways
Oil surged 70% in 10 days (Brent Crude $61 → $110), but historical data shows war alone doesn't crash Australian property.
Four Middle East wars over 50 years: property rose three out of four times. The one crash (1973) was caused by rates exceeding 10% — not the war itself.
Russia-Ukraine test run: Prices dropped 9.1%, bounced in 18 months, ended 23% higher than the pre-war peak.
262,000-home national shortfall and 420,000 annual population growth are the structural forces keeping the floor under prices.
All four major banks expect a May 2026 RBA hike to 4.10%, adding $180/month on a $600,000 mortgage.

Introduction
Oil is up 70%. The RBA just hiked. Your inbox is full of crash predictions. But here's a number most commentators won't tell you: across four Middle East wars spanning 50 years, Australian property rose three out of four times. The one genuine crash — 1973 — wasn't caused by bombs. It was caused by interest rates spiralling past 10%.
This article is based on Alex's in-depth video on the AusPropertyStrategy YouTube channel, where he walks through what he calls "the transmission chain" — the four-step mechanism connecting Middle Eastern conflict to your mortgage repayments. After reviewing 50 years of wartime property data, major bank forecasts, and a Wall Street firm's analysis of Trump's war playbook, the picture is more nuanced than the headlines suggest.

How Does the Iran War Reach Your Mortgage?
The Iran conflict impacts Australian mortgages through a four-step transmission chain: oil → petrol → inflation → interest rates. Brent Crude jumped from $61 to over $110 (up 70% in 10 days), and since Australia imports 90% of its fuel, every $10 rise in crude adds roughly 10 cents per litre at the pump.
This chain works with measurable precision. NRMA estimates this wave adds $25 to $30 to the cost of a full tank. Australia has only two refineries remaining, with strategic reserves lasting approximately 36 days. AMP's chief economist Shane Oliver calculated that a 40-cent-per-litre fuel increase adds 0.8 percentage points to CPI. Before the war, inflation sat at 3.8% — at the current pace, it could push past 4.6%.
When inflation rises, the RBA responds with rate hikes. The RBA raised to 3.85% on February 3, effectively wiping out most of last year's three rate cuts. All four major banks now expect another hike in May to 4.10%. According to Canstar's Sally Tindall, two hikes combined add $180 per month on a $600,000 loan and reduce borrowing power by $24,000. In my experience analysing property cycles, I call this "the closing window" — your buying capacity is actively shrinking with each step of this chain.

What Happened in the First Ten Days of the Iran Conflict?
On February 28, the US launched Operation Epic Fury jointly with Israel — 900 targets hit in 12 hours, killing Iran's Supreme Leader Khamenei in the first wave. Iran retaliated with over 2,500 missiles and drones striking Israel and US bases in Qatar and Bahrain. The UN declared a major humanitarian emergency with 330,000 people displaced.
The military side doesn't hit your wallet directly. What does is the Strait of Hormuz — the chokepoint carrying 20% of the world's daily oil supply. Iran shut it down on March 2. Shipping dropped 83% within 24 hours. Maersk and MSC halted all sailings. Insurers refused to cover the route. As of the script date, it had been closed for nine days and counting.
The single-week oil surge of 35% was the largest since futures trading began in 1983. But as I've tracked across decades of property cycles, the military escalation matters far less than what happens to rates and supply. That's where 50 years of data come in.

Did Australian Property Crash During Past Middle East Wars?
Across four Middle East wars since 1973, Australian property prices rose in three and fell significantly in only one. The critical variable was never the war itself — it was whether interest rates spiralled above 10%.
Here is how each conflict played out for Australian housing:
The 1973 case is the worst scenario. Oil rose 300% under a full OPEC embargo. Inflation reached 18%. Rates doubled to 10.38%. Mortgage repayments essentially doubled. But the damage came from rates exceeding 10% and staying there — not from the conflict itself. Recovery took 14 years.
The 1990 Gulf War is the closest parallel to today. Both involved a Middle Eastern war doubling oil prices, domestic economic stress layered on top, and a central bank agonising over rate direction. In 1990, rates were 17.5% heading down — today, 3.85% possibly heading up. Even at 4.35%, that is a different universe from 17.5%. Nationally, property only dropped 8%. Sydney fell 6.2%. Melbourne dropped 19% due to concentrated 1980s speculation. Brisbane actually rose 6.2%. By 1995, Sydney had reached new highs. By 2000, it had doubled.
The 2003 Iraq War saw property surge as a safe haven, with rates moderate and inflation stable. The pattern across 50 years is unambiguous: what determines the outcome is not bombs — it's whether rates spiral and whether your city has a speculative bubble.
<a id="what-did-russia-ukraine-already-prove-about-war-and-house-prices"></a>
What Did Russia-Ukraine Already Prove About War and House Prices?
The 2022 Russia-Ukraine war already stress-tested Australian property: prices dropped 9.1% nationally, bounced within 18 months, and ended 23% above the pre-war peak — proving that housing shortages override geopolitical shocks.
The numbers tell the full story. Oil surged from $78 to $139. Inflation rocketed from 3.5% to 7.8%. The RBA moved from 0.10% to 4.35% — a 425-basis-point hike, the fastest cycle in Australian history. Sydney fell 13.8%. But Perth dropped less than 1%. Adelaide fell only 1.3%. Why? Those cities had the worst housing shortages — and took the least damage.
By March 2023, prices were climbing again while rates were still rising. Listings were 31.5% below the five-year average. There simply weren't enough homes. This February, the national median reached $922,838 — 23% above the 2022 peak. In my analysis, people who panic-sold during Russia-Ukraine are now kicking themselves. This time, three factors are tougher: a larger oil shock, a higher starting inflation rate, and a thinner rate buffer. But the housing shortage is also worse.
<a id="how-accurate-are-bank-and-expert-forecasts-during-crises"></a>
How Accurate Are Bank and Expert Forecasts During Crises?
Expert property crash forecasts have been consistently wrong during geopolitical shocks — often by double-digit margins. Their track record should temper any panic triggered by current predictions.
The evidence is damning. In 2008, economist Steve Keen bet property would crash 40%. He lost the bet and walked to Mt Kosciuszko wearing an "I was hopelessly wrong" T-shirt. In 2020, CBA predicted falls of up to 32%. Shane Oliver called for 15–20% declines. What happened in 2021? A 25%+ surge — the biggest boom in 50 years. Oliver later admitted he was "quite embarrassed." In 2022, all major banks forecast 10–15% drops. The actual fall was 9.1%, and it recovered within a year. Even RBA Governor Philip Lowe said in October 2021 that rate hikes were "unlikely before 2024." Seven months later, the RBA hiked 13 consecutive times.
I don't trust any single forecast. I trust supply and demand, interest rates, and population growth. Within our Golden 11 Rules framework, these structural forces beat any crystal ball.
<a id="what-are-the-major-banks-predicting-right-now"></a>
What Are the Major Banks Predicting Right Now?
Major bank predictions are split: NAB warns inflation could hit 5%, while AMP still forecasts 5–7% property growth in 2026. The RBA itself acknowledged "it could go either way" at the AFR Business Summit on March 3.
RBA Governor Michele Bullock confirmed the March 17 meeting is "live," then made the counterintuitive observation that a prolonged war "could push inflation down" as consumers spend less. On the bearish side, NAB's 5% inflation warning would match levels not seen since Russia-Ukraine in 2022. On the bullish side, AMP's Shane Oliver argues expensive oil is a "tax on spending" — people drive less, demand drops, and inflation eases. Additionally, Australia is a net energy exporter, meaning higher gas and coal prices actually improve the trade balance.
Westpac modelled two scenarios: a one-month Strait of Hormuz closure means oil at $113 and one percentage point added to inflation. A three-month closure means $185 oil and 1.5 points. As of the script date, we are already in scenario one.
<a id="how-long-will-the-iran-war-last"></a>
How Long Will the Iran War Last?
A Wall Street research firm, the Kobeissi Letter, decoded Trump's war playbook as a 10-step script identical to his trade wars — and places the conflict at steps 6–7, approaching the exit. The US Energy Secretary stated, "This is weeks, not months."
The playbook follows a pattern: talk tough, flex military muscle, strike on a Friday when markets are closed, let Monday's crash create panic, then float a "we're open to talks" signal. The deal gets done, markets rally, and Trump takes credit. Kobeissi identified three red lines constraining duration: Trump promised to be the "peace president," to lower inflation, and to reduce petrol prices to $2. Every extra day of war breaks those promises. US fuel has already moved from $2.92 to $3.45. CNN polls show 60% oppose the action. The 2026 midterms loom.
The New York Times reported on March 4 that Iran made a back-channel offer — give up nuclear weapons in exchange for regime survival. As of the recording date (March 10), oil had dropped from $100 to $85 over the weekend. Trump signalled the war could end soon. Oil tankers in the Strait of Hormuz had started limited runs. The experts, as Alex noted, "got their faces slapped faster than anyone expected."
<a id="can-australias-housing-shortage-absorb-the-shock"></a>
Can Australia's Housing Shortage Absorb the Shock?
Australia's 262,000-home national shortfall is the structural force keeping a floor under property prices through any geopolitical storm. With 420,000 people added annually and vacancy at 1.2%, the maths overwhelms any war-driven correction.
The National Housing Accord target is seriously behind schedule — only 177,000 homes were built in 2024 against demand of 223,000. This January, approvals fell another 7.2%. The gap widens every month. Of the 420,000 annual population increase, 72% comes from overseas migration. National vacancy sits at 1.2%, Perth at 0.6%, Brisbane at 0.9%. Rents have climbed 47% over the past five years.
The contrast across history is instructive. In 1973, there was no housing shortage of this magnitude — and recovery took 14 years. In 2022, Perth (with extreme shortages) barely moved during the correction and then led the rally. Property right now is being pulled by two opposing forces: war closing the window through oil, inflation, and rates — and 262,000 missing homes plus 420,000 new arrivals forcing it open. Over 50 years, every external shock — oil crisis, financial crisis, war — the side pushing that door open has always won.
<a id="what-should-property-investors-do-right-now"></a>
What Should Property Investors Do Right Now?
The Iran war's impact on Australian property will likely be smaller than most expect. The strategy: keep buying with sensible leverage, maintain a cash-flow buffer, and don't max out borrowing — because the housing shortage won't vanish due to a war.
Population growth won't stop because of the Middle East. Homes won't materialise by the tens of thousands because the Strait of Hormuz is closed. But preparation matters. If oil stays above $100, rates push past 4.35%, and prices pull back — that correction becomes the best buying window of the next three years.
The Russia-Ukraine experience is the clearest guide: dropped 9.1%, bounced in 18 months, ended 23% higher. What decides your property's value isn't bombs in the Middle East — it's whether there are enough homes for the people who need them. Four wars. Fifty years. That answer has never changed.
<a id="frequently-asked-questions"></a>
Frequently Asked Questions
Will the Iran war cause an Australian property crash?
Historical data from four Middle East wars spanning 50 years shows Australian property rose three out of four times. The single significant decline (1973) was driven by interest rates exceeding 10%, not the conflict itself. With rates currently at 3.85% — even a hike to 4.35% is far below that danger threshold.
How much will mortgage repayments increase from the Iran conflict?
All four major banks expect the RBA to hike to 4.10% in May 2026. Combined with the February hike, Canstar calculates this adds $180 per month on a $600,000 loan and reduces borrowing power by $24,000.
How does the Strait of Hormuz closure affect Australian fuel prices?
Australia imports 90% of its fuel and has only two remaining refineries. Every $10 rise in Brent Crude adds approximately 10 cents per litre at the pump. NRMA estimates the current oil shock adds $25–$30 per full tank. Strategic reserves would last roughly 36 days.
How long is the Iran war expected to last?
The Kobeissi Letter places the conflict at steps 6–7 of Trump's 10-step playbook, approaching an exit. The US Energy Secretary stated it will be "weeks, not months." Iran has reportedly made a back-channel offer, and oil dropped from $100 to $85 as of March 10 with limited tanker runs resuming.
What happened to Australian property during Russia-Ukraine?
National prices dropped 9.1% as the RBA hiked from 0.10% to 4.35%. Perth fell less than 1%, Adelaide only 1.3% — cities with severe housing shortages took the least damage. By February 2026, the national median reached $922,838 — 23% above the 2022 peak.
How big is Australia's current housing shortage?
The national shortfall stands at 262,000 homes. Only 177,000 were built in 2024 against 223,000 demand. Population grows by 420,000 annually (72% from overseas). National vacancy is 1.2%, Perth 0.6%, Brisbane 0.9%, and rents are up 47% over five years.
Should I wait for a crash before buying property?
Based on 50 years of data, every wartime correction has recovered — and waiting has consistently cost more than buying through the dip. During Russia-Ukraine, those who panic-sold during the 9.1% decline missed the subsequent 23% rebound within 18 months.
Can RBA rate hikes push property into a sustained downturn?
The critical threshold from historical data is rates above 10%. In 1973, rates hit 10.38% and recovery took 14 years. Current rates at 3.85% (potentially 4.35%) are far below that danger zone. Even during 2022's fastest hike cycle in history (425 basis points), prices recovered within 18 months.
Conclusion
Four Middle East wars. Fifty years of data. Property rose three out of four times. The single crash came from rates exceeding 10% — not from the conflict. The 2022 Russia-Ukraine war gave us a live test run: a 9.1% drop, an 18-month bounce, and a 23% gain above the peak. Today's 262,000-home shortfall and 420,000 annual population growth create a structural floor that no geopolitical event has ever broken. The Iran war will affect sentiment and short-term rates. But supply and demand — not bombs — determine property values.
