| 2026 7–11 Oct | Middle East / energy shipping | Hormuz escalation moved to the bypass route: on 7 Oct Iran said it would close the 'illegal' southern route hugging Oman's coast, and a tanker was hit by 'multiple projectiles' off Qatar (~500km west of the strait). On 9-10 Oct the IRGC said it struck the LPG carrier NV Sunshine on that route, and UKMTO reported a projectile fire on the crude tanker GEM NO2 off the UAE. Trump said on 8 Oct the US will not attack Iran before the 3 Nov midterms. On 11 Oct Iran's security council head called the latest US response 'insufficient'. Brent futures settled US$104.72 on 9 Oct (US$100.20 on 7 Oct). | Brent and oil-linked Asian LNG prices; Australian fuel inflation and so the RBA; LNG export receipts; Asian importers' terms of trade | The Guardian, 2026 8 Oct Asharq Al-Awsat / AFP, 2026 10 Oct |
| 2026 6–8 Oct | Middle East / energy shipping | Strait of Hormuz: tanker attacks hit their highest weekly level since the Iran war began (2026 28 Feb). Only seven commodity vessels transited on 6 Oct (lowest since 23 Jul), and crude through the strait fell to ~10.1 mb/d, 74% of pre-war (Kpler). Gulf exports rerouted via the Gulf of Oman and the Red Sea kept total Middle East crude exports near pre-war levels. | Brent and oil-linked Asian LNG prices; Australian fuel inflation (and so the RBA); LNG export receipts; Asian importers' terms of trade | The National / Reuters, 2026 8 Oct |
| 2026 10 Oct | Fuel security / Russia | Trump announced a deal for Russia to supply 300,000 tons of diesel to the US and global markets immediately, then 500,000 tons in November, rising later to 3m tons. Energy Minister Bowen said Australia does not 'need or want' Russian fuel and will not change its approach. Australia holds 43 days of petrol and 31 days of diesel, with 51 fuel ships en route and 3.2bn litres contracted over the next four weeks. | Global diesel supply and margins; Australian diesel and freight costs (CPI automotive fuel, and so the RBA); mining and farm input costs; friction with US sanctions policy | The Guardian, 2026 10 Oct ABC News, 2026 10 Oct |
