Last week, Australian petrol prices shot up sharply, marking the biggest weekly increase since tensions flared between the US and Iran earlier this year.

The sudden surge followed the collapse of ceasefire negotiations in mid-April, reigniting concerns over oil supply via the Strait of Hormuz, a key but vulnerable passageway that handles about 20% of the world’s oil shipments.

Brent crude oil prices jumped 5.7% to $95.50 per barrel swiftly after the talks failed.

Since Australia relies heavily on imported fuel, these international price changes hit local petrol stations almost immediately, with little domestic cushioning to soften the blow.

Before the diplomatic breakdown, prices had fallen about 5% to A$2.40 per litre in early April the first notable drop since February.

Diesel prices climbed near A$3.13 per litre, reaching new highs before easing slightly. Elevated diesel costs affect not only drivers but also freight, farming, and construction sectors, pushing up costs across the board.

The Strait of Hormuz narrows to just 33 kilometres at its tightest, positioned along Iran’s coast.

Cryptocurrency markets also felt the ripple effects. Bitcoin fluctuated between $63,000 and $74,000 amid the geopolitical tension. Ethereum and Solana mirrored this movement, with broader token markets weakening as energy price worries intensified.

Investors now face uncertainty as the failure of mid-April talks removed hopes for short-term stability in oil prices.

Australia’s central bank faces increasing challenges balancing inflation concerns with economic growth, as fuel price spikes feed directly into inflation numbers and influence interest rate expectations.
