In case you’ve heard about “coverage divergence” in foreign exchange, you most likely discovered a easy rule: when one central financial institution raises charges whereas one other holds regular, the foreign money of the climbing financial institution tends to understand. It’s one of the dependable forces in foreign money markets.
However proper now, that rule is being put to the take a look at in an enormous approach, and EUR/USD is the pair caught within the center.
The Iran battle that erupted a number of weeks again despatched oil costs surging previous $100 per barrel. Europe, which depends closely on imported power, is now going through renewed inflation stress. Markets are abruptly pricing within the chance that the European Central Financial institution (ECB) may really hike charges whereas the U.S. Federal Reserve stays on maintain. That must be straightforwardly bullish for the euro, proper?
Not precisely.
The Fundamentals: The ECB’s Dilemma
The ECB entered 2026 in a snug spot. The deposit charge was sitting at 2.0%, inflation had fallen again close to the two% goal, and central bankers described coverage as being in a “good place.” Charge hikes weren’t on anybody’s radar.
Then the Iran battle broke out late February when U.S. and Israeli forces launched coordinated strikes. Iran closed the Strait of Hormuz, the passage by which roughly 20% of world oil flows, and crude oil costs skyrocketed to file highs in a matter of days.
For Europe, this can be a significant issue. The eurozone is an enormous power importer. When oil and fuel costs soar, inflation goes up quick, so the ECB could really feel compelled to reply.
Earlier than the battle, futures markets noticed virtually zero likelihood of an ECB charge hike in 2026. Inside two weeks, that had flipped dramatically, with swaps pricing in a roughly 70% likelihood of two 25-basis-point hikes by year-end, with a primary hike totally priced by July.
On the flip facet, the Federal Reserve appears set on staying put.
The Fed’s benchmark charge is at present at 3.5–3.75%. Earlier than the Iran battle, merchants had been anticipating charge cuts in June and September. Now, with oil costs including to already-above-target U.S. inflation (CPI was 2.4% in February), these reduce bets have been pushed again considerably. Merchants now see at finest one reduce, presumably in December.
So now we have a real coverage divergence establishing: the ECB doubtlessly climbing, the Fed standing nonetheless and even retreating on its reduce timeline.
Why It Issues: The Coverage Plot Twist
Usually, right here’s how coverage divergence works:
ECB hikes → euro turns into extra engaging to carry → EUR/USD goes up
Fed holds → greenback turns into comparatively much less engaging → EUR/USD goes up
Each elements ought to push EUR/USD increased. But the euro has really been weakening. In keeping with Bloomberg, the euro has dropped greater than another main foreign money because the Iran battle started, falling from above $1.20 to close $1.15 in a matter of days.
Why? As a result of the rationale for the ECB’s potential charge hike issues enormously.
The ECB isn’t climbing as a result of the eurozone financial system is booming. It could be climbing to combat inflation brought on by an power disaster that’s concurrently crushing European progress. Greater power costs act like a tax on European companies and customers.
Oxford Economics estimates eurozone inflation might run 0.5–0.6 proportion factors increased in late 2026 than beforehand forecast whereas GDP progress might sluggish to as little as 0.8% if the shock intensifies.
Briefly, the ECB could hike right into a weakening financial system. That’s a really completely different scenario from elevating charges as a result of issues are going properly.

Key Classes for Merchants
1. The explanation for tightening issues, not simply the hike itself.
A central financial institution elevating charges to combat a progress increase could be very completely different from climbing to combat a supply-side power shock. Within the first case, a powerful financial system helps the foreign money. Within the second, rising charges combat inflation whereas the underlying financial system deteriorates, making the foreign money much less engaging, no more.
2. Coverage divergence is a spectrum, not a swap.
The ECB may hike. The Fed may keep on maintain. However each are responding to the identical exterior shock. The diploma of divergence, and who it helps extra, relies upon totally on how the power scenario evolves week by week.
3. Protected-haven flows can override fundamentals — not less than briefly.
When geopolitical threat spikes, merchants rush to the U.S. greenback no matter charge differentials. The greenback strengthened broadly when the Iran battle broke out, even whereas the Fed had no plans to boost charges. Worry trades can final weeks or months.
4. Europe’s power dependence is a structural FX vulnerability.
This isn’t the primary time an power shock has damage the euro. The 2022 Russia-Ukraine battle did the identical factor. Every time international power markets are disrupted, Europe tends to undergo disproportionately, and the euro displays that publicity.
5. Watch the period, not simply the headline.
If the Iran battle resolves rapidly and oil normalizes towards $70–80/barrel, the inflation shock may very well be manageable and ECB hikes could not materialize. If the battle drags on for 3 to 4 months, the macro harm turns into extreme. The size of the disruption is what determines whether or not EUR/USD finally recovers.
The Backside Line
The scenario in EUR/USD proper now could be a masterclass in why foreign exchange is extra complicated than “increased charges = stronger foreign money.”
The ECB could elevate charges in 2026, presumably earlier than the Fed does something. But when these hikes are pushed by energy-shock inflation whereas the eurozone financial system slows, they might do little to help the euro and will even damage it if merchants learn them as an indication of how burdened Europe’s financial scenario actually is.
Watch for 3 issues going ahead: how lengthy the Iran battle lasts, whether or not European power costs stabilize, and what the ECB alerts at its March 19, 2026 assembly. These information factors will inform you much more about EUR/USD’s route than the speed differential alone.
