Good morning and welcome to NexoBrief. The world woke up to a lot this weekend — oil above $100, markets rattled, and your wallet already feeling it. Here's everything you need to know in 5 minutes.
⚡ BIG STORY
The Strait of Hormuz Is Closed — And It's Hitting Your Wallet Right Now
The US-Israel war on Iran is now in its third week and the economic ripple effects are landing directly in your daily life. The Strait of Hormuz — a narrow waterway off Iran's coast that carries roughly 20% of the world's oil supply — has been effectively shut down since the conflict began on February 28. The result: oil prices have surged from around $70 per barrel before the war to over $100 this week, briefly touching $120 last week.
What that means for you today:
Gas prices have jumped 60 cents per gallon nationally since the war began, hitting an average of $3.58 as of last week. Groceries are next — food gets to your store on diesel, and those transportation costs are already climbing. Mortgage rates ticked up to 6.11% this week as bond markets priced in higher inflation. The Federal Reserve, which was expected to cut rates this spring, is now almost certainly on hold.
The emergency response: 32 nations agreed this week to release 400 million barrels of emergency oil reserves — the largest such release in history. The US alone is contributing 172 million barrels from its Strategic Petroleum Reserve. But analysts say it's a temporary fix. At current supply gaps, those reserves cover just 26 days.
NexoBrief take: This is the story that touches everything in 2026 — your gas bill, your grocery bill, your mortgage rate, and your investment portfolio. We will keep tracking it every morning so you always know exactly where things stand.
💰 MONEY MINUTE
How to Protect Your Money During an Oil Shock — Right Now
When oil prices spike the way they have this week, the pain isn't just at the gas pump. It flows through the entire economy — higher transportation costs, higher food prices, higher inflation, and a stock market that gets very nervous. Here's what NexoBrief recommends thinking about right now:
Lock in your fixed costs where you can. If you have a variable rate on anything — a credit card balance, an adjustable rate mortgage, a personal loan — higher inflation means higher rates are coming. Pay down or refinance now while you still have options.
Energy stocks are a natural hedge. When oil prices spike companies like ExxonMobil, Chevron, and ConocoPhillips tend to benefit directly. If you want portfolio exposure to the current environment, energy ETFs like XLE are worth researching. Not financial advice — do your own research.
Your grocery bill is about to go up. Stock up on non-perishables now before transportation cost increases hit retail shelves. This sounds basic but the timing window between oil price spikes and grocery store price increases is typically 4-8 weeks.
NexoBrief quick take: You can't control oil prices or wars. You can control whether you're prepared. A few smart moves this week can save you real money over the next 3-6 months.

🚀 STARTUP SPOTLIGHT
The Oil Shock Is Creating a New Wave of Energy Tech Startups
Every major energy crisis in history has accelerated investment in energy alternatives — and this one is no different. Within days of the Strait of Hormuz closure, venture capital firms began announcing accelerated funding for energy security startups across three categories: domestic oil and gas production technology, renewable energy infrastructure, and energy storage.
The startups NexoBrief is watching right now: Fervo Energy — a geothermal startup that just raised $244M to build always-on clean electricity that doesn't depend on Middle East oil. Rondo Energy — a heat battery company backed by Bill Gates that stores industrial heat from renewable sources. Form Energy — an iron-air battery startup building week-long energy storage to stabilize grids during supply disruptions.
The bigger signal: Every time the world is reminded how exposed it is to a single shipping lane controlling 20% of global oil supply, the investment case for energy independence gets stronger. The startups building that independence are some of the most important companies being funded right now.
NexoBrief take: The Iran war is painful in the short term. But it is accelerating a multi-trillion dollar energy transition that was already underway. The companies at the center of that transition are worth paying attention to.
🌍 CURRENT EVENTS
What's Actually Happening in the Middle East — Explained Simply
With 24/7 news coverage moving fast and sometimes in conflicting directions, NexoBrief is here to give you the plain facts. Here is where things actually stand as of this morning:
The war: The US and Israel launched joint airstrikes on Iran on February 28. The conflict is now in its 16th day. Iran's original supreme leader Ali Khamenei was killed early in the conflict. His son Mojtaba Khamenei has assumed leadership and has vowed to keep the Strait of Hormuz closed as a tool of economic pressure.
The diplomacy: President Trump told NBC News this weekend that Iran wants to make a deal but that the terms aren't good enough yet. Iran's foreign minister said the country is open to talks with countries wanting safe passage through the Strait. A G7 virtual summit is being organized this week to coordinate the global response.
The human cost: More than 1,400 people have been killed since the war began. Over 10,000 homes in Tehran have been damaged or destroyed. Iran has retaliated with missile strikes on Israel and attacks on US allies in the Gulf region.
NexoBrief take: This is a rapidly evolving situation. The most important variable for your finances is how long the Strait of Hormuz stays closed. Every week it remains shut adds roughly 0.2-0.3% to US inflation. We will update you every morning with what matters most.
