US-Iran War Drives Oil Prices Higher as Chinese EV Makers Sweep European and Australian Markets

The Iran war has lifted European petrol prices 45% year-to-date, crushing combustion-vehicle demand; BYD's May sales in Germany, France, and Italy each surged over 200% year-on-year — high fuel costs are herding consumers straight toward Chinese EVs.

01

How much did European fuel prices rise — and how far did combustion sales fall?

European petrol prices have climbed 45% since the start of the year, after war broke out with Iran in February; a ceasefire trimmed 6.5% off the peak, but absolute prices remain elevated.
Pure combustion-vehicle sales in May fell 20% YoY in Germany, 40% in France, and 19% in Italy.
This means → oil prices don't need to keep hitting new highs; staying elevated is enough to drive consumers away from petrol cars.
02

How big is the windfall for Chinese automakers?

BYD's May sales jumped 232% YoY in Germany, roughly 230% in France, and 209% in Italy.
Gartner research VP Pedro Pacheco called the shift "absolutely massive gains."
In plain terms = European buyers aren't gradually warming to EVs — they are switching en masse, and the cheapest, most available options on the shelf are Chinese brands.
03

What is happening in Australia?

The Tesla Model Y became Australia's best-selling vehicle in May, up 57% YoY.
BYD ranked as Australia's second-best-selling brand for the second straight month, behind only Toyota.
Pure EVs hit 20% of total sales in May; including hybrids and plug-in hybrids, the electrified share reached 46.4%, up from 27% a year earlier.
Australia subsidises petrol by 18%, but that subsidy expires June 30 — consumers are clearly front-running the expiry by buying electric now.
04

How strong are the export numbers — and can they go higher?

Chinese EV exports rose 94% YoY last month; analysts had forecast full-year growth above 80%.
That figure may be revised upward: China's Ministry of Industry and Information Technology and market regulator recently convened automakers, demanding they rein in the domestic price war.
This means → when companies can't fight on price at home, they push volume abroad. Regulatory pressure is effectively accelerating exports, not curbing output.
05

Has this happened before?

During the 1970s oil crisis, Japanese automakers filled the gap left by Detroit's gas-guzzlers with fuel-efficient compacts — and broke into the U.S. market in one stroke.
China's playbook today is strikingly similar: a flood of EVs priced below $35,000 — some under $20,000 — expanding fast in a window where Western incumbents lack competitive alternatives.
In plain terms = fifty years ago Japan won America with "fuel-efficient"; today China is winning Europe and Australia with "no fuel at all" — same logic, just a more complete energy substitution.
