The breakup didn’t stick. Oil’s ex is officially back.

Here's what you need to know this week, and why it matters.

We all know how this story goes. The breakup finally happens, the group chat celebrates, and you delete all the photos. Life starts to feel lighter. You start to feel like you are getting your spark back. Then one Friday your phone lights up with a new notification. He is back. Back like he never left.

In Issue 5 we told you the oil market was in a situationship with peace. A ceasefire was forming between the US and Iran, nobody would define it, and an ex kept threatening to ruin the whole thing. This week that is exactly what he did. The truce broke, the strikes are back, and the calm that had settled over the oil market since June is gone.

Brent crude, the international benchmark price for oil, rose to $85.76 a barrel on Friday, and WTI, its American counterpart, reached $80.64. Both are up nearly 13% this week, with Brent heading for its third weekly gain in a row and WTI for its second.

For perspective, when we wrote Issue 5 just a month ago, both were at their three month lows. That is just how quickly a market can change. And this time, he’s not just texting you. He showed up at your front step.

The fighting itself has escalated on both sides. US Central Command said American forces have begun a new wave of strikes against Iran. It marked a sixth straight night of US attacks on Iranian military facilities. Iran hit back with fresh strikes on US facilities across the Middle East, including its first direct attack in Syria.

And the fight is dragging in the neighbours.

Qatar’s defence ministry said its forces intercepted an Iranian missile attack early Friday, and the country’s interior ministry reported that a child was injured by shrapnel. Shrapnel is the flying metal fragments left behind when a missile is destroyed in the air.

In Kuwait, the electricity ministry said one of the country’s power and water desalination stations was hit. A water desalination station is a facility that turns seawater into drinking water, which much of the Gulf relies on because fresh water is scarce there.

Attacks on civilian infrastructure in two more Gulf countries in a single week are not a side detail. It is exactly the kind of escalation that keeps a risk premium alive. This isn’t a one-text apology and flowers. This is him showing up at your office, your yoga class, your favourite coffee shop, all in one week.

But here’s what’s actually moving the price, and it comes down to geography.

The Strait of Hormuz, the narrow waterway we covered in Issue 1 that carries around 20% of the world’s oil, has seen flows drop since the truce broke. The fighting makes the route riskier to sail, and fewer ships are willing to take that risk. But that oil still had to get out of the Gulf somehow, so shippers found another way.

Saudi oil exports were rerouted away from Hormuz and through the Red Sea instead. That shift also shows up in the data, where Commerzbank analysts found that Red Sea transit has increased significantly since the war began. Think of Hormuz as Plan A and the Red Sea as Plan B. So basically, when Plan A got restricted, the whole market moved to Plan B.

But now Plan B is under threat too.

Iran is pressing the Houthi movement, an armed group based in Yemen that controls territory along the Red Sea coastline, to close the route if the US strikes Iran’s power infrastructure. Closing a sea is not really possible, but closing the narrow strait ships must pass through to get in and out of it is, and that strait has a name. The Red Sea’s southern entrance is called Bab al-Mandab, and Commerzbank warns that if the conflict escalates further and a blockade happens there, oil prices would likely climb even higher.

This is the real story this week. It isn’t about one waterway anymore. It is about both of the ways Gulf oil gets out to the world being at risk at the same time. Plan A is compromised. Plan B is under threat. There’s no backup plan left to fall back on. No “at least I still have Plan B” text to send your friends. Both exits are compromised at once, and that’s a very different kind of breakup to manage. That is why the price moved 13% in a week rather than 2% in a day.

That kind of price move tends to catch the attention of the people whose job it is to stay calm, and this week it did. Fatih Birol, Executive Director of the International Energy Agency, the organization that tracks and forecasts global energy markets, told a Council on Foreign Relations event in Washington that oil security remains a critical concern. His exact words were, “We should be worried, and I am worried,” and he tied that concern to the coming weeks, not days.

And that timeline is exactly where this lands on you. Back in Issue 1 we wrote that rising energy costs work their way into everything, including your groceries, your electricity bill, and the girls’ trip that somehow costs more every time you check. That pressure had started to ease while the ceasefire held.

Now the ex is back on the doorstep, and the sections ahead break down what is genuinely new, what is noise, and what it all means for your money. But first, since every number in this issue is technically a futures price, let’s talk about how oil actually gets its price.

What’s moving in markets

Note: The article this issue is built on covers oil and the conflict itself. The moves described below are informed context based on how markets reliably behave in weeks like this.

Oil is the entire story this week. Brent rose 1.82% to $85.76 and WTI rose 2.14% to $80.64, with both benchmarks up nearly 13% on the week. The driver is the rebuilt geopolitical risk premium, the extra price markets add because of conflict fears. We watched that same premium fade during the ceasefire in Issue 5, but this time it’s come back higher, since the threat now covers both of oil’s exit routes at once.

The US dollar strengthens in weeks like this. As we saw in Issue 1, investors move toward safe havens like the dollar when geopolitical risk rises. On top of that, with energy inflation threatening to return, markets are betting central banks will wait even longer to cut rates, which keeps US yields attractive. Both forces pull in the dollar’s favour at once.

Emerging market currencies take the hit from both sides. Countries that import their energy pay more for oil while capital flows away from them toward the dollar, a compounding problem for economies that are already under financial pressure.

Equities split down the middle. Energy producers benefit directly, since less supply means higher prices and stronger revenues. The pressure lands hardest on everyone who consumes energy at scale, from transport and airlines to the AI infrastructure buildout that depends on huge amounts of electricity. Credit conditions tighten too, as uncertainty raises the cost of borrowing for companies. That eventually shows up as slower investment and hiring in the months ahead.

Currency & interest rate

Note: This week’s article does not cover currencies or interest rates. The analysis below is informed context, not sourced from the article.

How it all connects

Truce breaks → Hormuz oil flows drop → Saudi exports reroute through the Red Sea → Iran threatens to close Bab al-Mandab → both chokepoints at risk at once → risk premium rebuilds → oil up ~13% in a week → inflation pressure returns → rate cuts pushed further out

What makes this shock so hard to manage is that it is a supply problem, not a spending problem. Interest rates are the tool central banks use to slow down how much people and businesses spend, and that tool works when the issue is too much demand chasing too few goods. It does nothing when the actual goods, in this case oil, cannot physically get to where they need to go. A central bank can raise or lower rates as many times as it likes. It cannot make the Gulf’s waterways safe to sail. That mismatch between the problem and the tools available to fix it is why this conflict can ripple through your currency, your borrowing costs and your portfolio all at once. No central bank can do anything to stop it directly.

What is different this time is the speed. When the ceasefire first formed, the risk premium took weeks to fade, as markets slowly convinced themselves the peace would hold. This time it rebuilt in a matter of days. Markets are no longer pricing one chokepoint, they are pricing two, and they have watched this exact pattern play out before. The first time the truce was threatened, the market needed convincing that it was serious. This time, it believed the threat immediately. A near 13% move in a single week is what that looks like.

Why this matters to you

The broader market picture

Markets are broadly in a risk-off mood, meaning investors are moving toward safer assets like the dollar while the conflict escalates. The relief timeline has been reset yet again. In Issue 5 the story was falling oil and eventual rate cuts, in Issue 7 the ECB told us peace alone would not fix inflation, and this week even the falling oil part is gone. For anyone quietly counting on cheaper energy and cheaper borrowing this year, the planning assumption needs to change from “when this ends” to “if this lasts.”

If you are building your financial literacy

The skill this week is understanding that the oil price in the headlines is a price of expectations. The market simply looked at two narrow waterways, imagined tomorrow, and repriced it.

If this connects to your work or portfolio

For those of you running a business or investing, here is what this week’s story means a little closer to home.

• If you are an importer: Energy, freight and insurance costs are rising, and if your own currency isn’t the dollar, its current strength means it takes more of your money to cover the same bill. Worth being aware if your planning assumes oil settles down in weeks, since the IEA itself is worried this could run for months.
• If you are an exporter: A firm dollar can flatter the rate on dollar receivables for now. Worth knowing that part of that strength comes from safe haven flows, which can fade as quickly as the fear that created them. This means that the rate you see today is not guaranteed to hold.
• If you are a borrower: Rate cut hopes are declining, so floating rate debt stays expensive for longer. The fixed versus floating question is back, and it’s worth keeping an eye on if you’ve been assuming cuts were close.
• If you are an investor: Energy holdings benefit while rate sensitive positions face pressure. The question worth sitting with is whether your portfolio can handle elevated energy prices and higher rates if this drags on longer than expected.
