Trump's 48-hour ultimatum to Iran — demanding the Strait of Hormuz reopen or face strikes on Iranian energy infrastructure — has sent shockwaves through global markets and raised the very real prospect of a wider Middle East war. Iran isn't blinking: it's threatening to close Hormuz entirely and target desalination plants and energy facilities across the region. With six fuel tankers to Australia already cancelled, this one hits close to home.

What Matters Today

• Iran-US standoff escalates fast. Trump issued a 48-hour deadline for Iran to reopen the Strait of Hormuz or face strikes on power plants. Iran responded by threatening to destroy desalination and energy infrastructure across the Middle East and close Hormuz to "enemy-linked" ships. ~1,500 civilian casualties reported since the US-Israel campaign began. This is the most dangerous moment in the conflict so far. Guardian AU
• Australia's fuel supply is wobbling. Six oil tankers scheduled to deliver fuel to Australia have been cancelled or deferred. The energy minister confirmed it, though officials are downplaying shortage risk. Expect price bumps at the bowser — and watch this space carefully. r/australia
• Almost half of Australians now expect a foreign military attack within five years. A new ANU study shows a sharp spike in national security anxiety, with the biggest jump among 18–24 year-olds. Timely, given everything above. Guardian AU
• Israel is escalating on multiple fronts. Settlers carried out coordinated attacks on Palestinian villages in the West Bank while security forces stood by. Separately, Israel is expanding ground and air operations in Lebanon, with fears of a large-scale invasion. Iranian missiles injured 180 near Israel's nuclear site at Dimona. BBC World
• Firefox 149 ships with a free built-in VPN — 50GB/month. Mozilla is making a real play for privacy-conscious users. No third-party app required. Given Australia's age verification laws and GrapheneOS refusing to comply with them, the timing is interesting. r/technology
• OpenAI is bringing ads to ChatGPT's free tier. The inevitable monetisation creep arrives. Free users in the US will start seeing ads, signalling the "AI as utility" era is getting a very familiar business model attached to it. r/technology
• Robert Mueller, ex-FBI director who led the Trump-Russia probe, has died at 81. A consequential figure — his investigation defined a political era and his conclusions (or non-conclusions) remain debated to this day. BBC World

Markets

It's a sea of red and the Iran crisis is the driver — the ASX 200 shed 7.2%, the S&P 500 fell 5.8%, and the Nikkei dropped 7.1% in one of the sharpest coordinated sell-offs in years. Energy supply fears and geopolitical risk premium are hammering equities hard across the board. The AUD slipped to USD 0.70, and in a deeply weird twist, gold — normally the safe haven of choice — cratered 12%, possibly hit by forced liquidations or margin calls. Bitcoin held its own with a modest 0.8% gain, and Ethereum actually popped 5.2%, suggesting some rotation into crypto as an uncorrelated hedge.

Worth a Read

• The stakes are enormous: how a prolonged Iran war could shock the global economy — Guardian economists break down what sustained conflict means for oil prices, inflation, and growth. Spoiler: it's not good, and Australia's exposure through fuel imports makes it required reading right now. Guardian AU
• GrapheneOS refuses to comply with new age verification laws — The privacy-focused OS says it will never require personal information from users, putting it on a collision course with new legislation. An important flashpoint in the OS-level surveillance debate that's coming whether we're ready or not. r/technology
• Trump timed his Iran ultimatum to land when markets reopen — The r/stocks thread dissecting the deliberate timing of the geopolitical threat is genuinely sharp. Markets as leverage — or leverage creating market chaos. Either way, worth the read. r/stocks
