Picture Christine Lagarde on Thursday morning. In front of her sit two folders. One contains a forecast she would not have dared to write three months ago: inflation in 2026 at 3.0%, well above her last estimate of 2.6%. The other contains the official statement in which the ECB raises rates. For the first time since 2023.
It is not a decision she takes with pleasure. But between those two folders sits something she cannot ignore: the Strait of Hormuz, a conflict with Iran that refuses to recede, and an oil price that is eating away at the European economy from within.
On Thursday 11 June, the ECB raised its key rates by 25 basis points, bringing the deposit rate to 2.25%, the first hike since 2023. Europe jumped. America stayed put.
Two central banks, one problem
And that, really, is the story of this week. The same problem, two completely different answers.
In America, the May inflation print landed on Tuesday. Annual inflation rose to 4.2%, the highest level since April 2023, accelerating for the third month in a row. Energy prices jumped 23.5% year-on-year, gasoline 40.5%, fuel oil 58.9%. Read that last number again. Petrol 40% more expensive than a year ago. These are no longer abstract percentages, they are a feeling at the pump.
Yet the market expects the Fed to hold rates steady at its 17 June meeting. No hike. No cut. A central bank putting the car on cruise control and hoping the bend in the road never comes.
Why? Because the core of the story is more interesting than the headline. Core inflation, excluding energy and food, rose just 0.2% on the month, below the forecast 0.3%. On an annual basis 2.9%. Translation: everything that is expensive, is expensive because of oil. The rest barely moves. If the Strait of Hormuz reopens next month, much of that inflation would melt away on its own.
The ECB is not waiting for that "if". The Fed is.
The elephant remains in the room
Meanwhile, one fact overshadows everything else: the war with Iran drags on. What started in March as a tense standoff has now become something economists are calling the Iran War with a capital W. Oil inventories are approaching the historic lows that Exxon's chief earlier this year described as "shock absorbers". If that buffer disappears, some analysts estimate Brent could climb to 150 to 160 dollars per barrel.
For context: a year ago Brent stood around 75 dollars. A doubling is no longer an unthinkable scenario, it is a scenario sitting in spreadsheets at the largest funds.
US markets catch their breath
The previous week, the S&P 500 had broken its winning streak. The index lost 2.55% on the week, while the Nasdaq gave up 4.65%, ending a remarkable run of nine consecutive weeks of gains. Not a crash, but a first clear note of doubt. Investors began asking themselves whether the rally that began in March had run too far.
This week sentiment stayed cautious. The CPI came in line with expectations, not soft enough for equities to celebrate, not hot enough to trigger panic. The market sits in a kind of twilight: no longer euphoric, not yet afraid.
A Fed with a new boss
And there was something else that got buried in the noise but is worth mentioning. Kevin Warsh has been the new chair of the Federal Reserve since 22 May, sworn in at the White House after a 54 to 45 Senate vote.
That is not a detail. A new Fed chair always brings uncertainty, especially in a period where markets parse every gesture, every sentence, every raised eyebrow. Warsh is known for hawkish views, but takes over in an environment where political pressure leans toward lower rates. How he squares that circle is a story for the second half of the year.
What do we take from this?
This week was not about a single event. It was about the growing gap between what central banks say and what they do, and between what consumers feel and what statistics measure.
The ECB did something striking by hiking into a weakening economy. At the same time the 2026 growth forecast was lowered to 0.8%, while the inflation forecast was raised to 3.0%. That is a central bank saying: we accept less growth to stay credible on inflation.
The Fed chooses a different route. Wait. Hope. Trust the idea that the Iran shock is transitory.
One of them will turn out to be right.
What does that mean for portfolios?
Oil and energy remain structurally expensive as long as there is no serious movement in the Hormuz negotiations. The position has not yet seen its top.
European bonds have become more vulnerable again. An ECB turned hawk means rising yields across the European curve.
The euro picks up support from a rate differential that is finally moving slightly in its favour. For exporters that is uncomfortable, for US investors in European equities it is a tailwind.
And the consumer? They are the quiet loser of this half year. A third straight month of rising inflation, wages that fail to keep up, and a pump that in parts of America sits above four dollars per gallon. Until that story turns, sentiment will stay fragile.
In quiet times, central banks follow the data. In times like these, they try to get ahead of it. Some by acting, others by sitting still. We will only know by the end of the year who read it correctly.
