How quickly will Australian petrol prices react to a global oil prices spike?

Most stations adjust with a lag of about 7 to 10 days because retailers buy fuel on rolling schedules. City price cycles can stretch or compress that timing. If disruption lasts, expect larger moves. If flows normalise quickly, the impact can be smaller and pass sooner.

Could crude really hit US$100 if the Strait of Hormuz stays blocked?

Yes, if shipping disruptions persist, reduced supply, higher freight, and risk premiums can push futures toward US$100. A quick reopening or stock releases could cap the move. Watch shipping data, OPEC-plus messaging, and insurance availability for a guide to the likely price path.

Will diesel and jet fuel in Australia rise as well?

Likely yes. Diesel tracks global distillate markets, so higher crude and tighter supplies lift wholesale prices that flow through to road freight and farming. Jet fuel tends to follow too, which can pressure airfares. The exact timing depends on supply contracts, inventories, and city or regional dynamics.

What indicators should investors watch to forecast oil prices near term?

Focus on Strait of Hormuz shipping status, war-risk insurance, tanker rates, OPEC-plus guidance, strategic reserve actions, and refinery margins. Also track the Aussie dollar, since currency swings change local fuel costs. A stable flow picture points to easing pressure. Persistent delays raise the odds of higher prices.

Pump impacts usually lag by 7 to 10 days, but the size of the move depends on how long flows stay blocked and how currency markets react.
