If you happen to’ve heard about “coverage divergence” in foreign exchange, you most likely realized a easy rule: when one central financial institution raises charges whereas one other holds regular, the foreign money of the mountain climbing financial institution tends to understand. It’s some of the dependable forces in foreign money markets.
However proper now, that rule is being put to the check in a giant method, 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 dealing with renewed inflation stress. Markets are immediately pricing within the chance that the European Central Financial institution (ECB) may truly hike charges whereas the U.S. Federal Reserve stays on maintain. That ought to 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 fee 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.” Price 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 means of which roughly 20% of world oil flows, and crude oil costs skyrocketed to document highs in a matter of days.
For Europe, it is a significant issue. The eurozone is an enormous power importer. When oil and gasoline costs soar, inflation goes up quick, so the ECB could really feel pressured to reply.
Earlier than the battle, futures markets noticed virtually zero chance of an ECB fee hike in 2026. Inside two weeks, that had flipped dramatically, with swaps pricing in a roughly 70% chance of two 25-basis-point hikes by year-end, with a primary hike absolutely priced by July.
On the flip facet, the Federal Reserve appears set on staying put.
The Fed’s benchmark fee is presently at 3.5–3.75%. Earlier than the Iran battle, merchants had been anticipating fee cuts in June and September. Now, with oil costs including to already-above-target U.S. inflation (CPI was 2.4% in February), these minimize bets have been pushed again considerably. Merchants now see at finest one minimize, probably in December.
So we have now a real coverage divergence establishing: the ECB doubtlessly mountain climbing, the Fed standing nonetheless and even retreating on its minimize 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 larger. But the euro has truly been weakening. In keeping with Bloomberg, the euro has dropped greater than every other 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 explanation for the ECB’s potential fee hike issues enormously.
The ECB isn’t mountain climbing as a result of the eurozone economic system is booming. It will be mountain climbing to struggle inflation attributable to an power disaster that’s concurrently crushing European progress. Increased power costs act like a tax on European companies and shoppers.
Oxford Economics estimates eurozone inflation might run 0.5–0.6 proportion factors larger in late 2026 than beforehand forecast whereas GDP progress might gradual to as little as 0.8% if the shock intensifies.
In brief, the ECB could hike right into a weakening economic system. That’s a really completely different state of affairs from elevating charges as a result of issues are going properly.

Key Classes for Merchants
1. The rationale for tightening issues, not simply the hike itself.
A central financial institution elevating charges to struggle a progress increase could be very completely different from mountain climbing to struggle a supply-side power shock. Within the first case, a robust economic system helps the foreign money. Within the second, rising charges struggle inflation whereas the underlying economic 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 fully on how the power state of affairs evolves week by week.
3. Secure-haven flows can override fundamentals — at the very least quickly.
When geopolitical threat spikes, merchants rush to the U.S. greenback no matter fee differentials. The greenback strengthened broadly when the Iran battle broke out, even whereas the Fed had no plans to lift 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 harm the euro. The 2022 Russia-Ukraine battle did the identical factor. At any time when world 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 might be manageable and ECB hikes could not materialize. If the battle drags on for 3 to 4 months, the macro injury turns into extreme. The size of the disruption is what determines whether or not EUR/USD finally recovers.
The Backside Line
The state of affairs in EUR/USD proper now could be a masterclass in why foreign exchange is extra advanced than “larger charges = stronger foreign money.”
The ECB could elevate charges in 2026, probably earlier than the Fed does something. But when these hikes are pushed by energy-shock inflation whereas the eurozone economic system slows, they could do little to assist the euro and will even harm it if merchants learn them as an indication of how burdened Europe’s financial state of affairs 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 let you know way more about EUR/USD’s route than the speed differential alone.
