Where EUR/USD might go

In late February 2026, the market received a headline that, at first glance, sounded purely legal and “dry,” yet in reality it touches the core mechanics of global trade and currency flows. The U.S. Supreme Court struck down large-scale global tariffs that had been introduced by the Trump administration under an emergency-powers framework. In other words, the Court restricted the White House’s ability to impose broad tariffs quickly through a single presidential move, without a clear and direct foundation in tariff-specific legislation.

For an ordinary reader, this may look like lawyers arguing over technicalities. For the FX market, it’s a direct hit to a lever that can shift inflation, economic growth, and investor risk appetite almost instantly. That means the event directly affects the dollar, the euro, and the EUR/USD pair.

Below is a clear explanation of what happened, why the market is reacting so nervously, and where things are most likely heading.

1) What Exactly Happened — and Why It Matters

────────────────────────────

The Court delivered a simple message: “emergency powers” are not a universal license to impose any tariffs worldwide. If the government wants to impose duties as a form of tax on imports, it needs explicit authority and strict boundaries — the kind of framework normally set by Congress.

Why does that matter to markets?

Because “broad tariffs” are not just politics. They directly affect prices, supply chains, corporate profits, and investor sentiment. Tariffs can:

• raise import prices → pushing inflation higher;

• worsen conditions for trade and business → slowing growth;

• trigger retaliation from partners → increasing global stress.

When the market realizes such a tool becomes harder to use, it often reads that as a reduced risk of sudden trade escalation. That’s why the first reaction can look like this: investors “exhale,” buy equities, and sell defensive positions.

But there’s an important nuance: the White House has already signaled it will look for other legal and administrative pathways. So uncertainty doesn’t disappear — it changes form and timeline.

2) Why Stocks Can Rise While the Dollar Weakens

────────────────────────────

The U.S. dollar is not only “America’s currency.” In periods of stress, it becomes the “stress currency”: when the world is nervous, capital often moves into the dollar and U.S. Treasuries because they are viewed as a baseline safe haven.

If the probability of a trade war decreases, part of the “insurance demand” for the dollar fades. That’s logical: less global fear → less need to hold the maximum share of defensive assets.

At the same time, a second force can appear: if the tariff cancellation implies potentially lower budget revenues (and possibly refunds of previously collected duties), the bond market may become uneasy. Investors start thinking about the budget deficit, debt load, and how much the government will need to borrow — and at what cost.

That is why the reaction can be mixed:

• equities up on relief;

• bonds down if “budget anxiety” rises;

• the dollar down due to reduced global stress — though not always and not for long (it depends on interest rates and Fed expectations).

3) Two Forces Pulling the Dollar in Opposite Directions

────────────────────────────

Right now, the U.S. is facing a particularly important combination.

Force #1: Growth is slowing.
Economic data suggests growth momentum has become noticeably weaker. That typically reduces the dollar’s appeal as the currency of the “stronger economy” and lowers expectations of an aggressively hawkish Fed.

Force #2: Inflation remains stubborn.
At the same time, inflation indicators remain firm. That means the Fed can’t easily and quickly cut rates. The market keeps hearing the familiar message: “rates may stay higher for longer.”

That’s why EUR/USD feels “sticky” and often shifts into a range:

• weaker growth → makes it hard for the dollar to rise confidently;

• stubborn inflation → makes it hard for the dollar to fall confidently (higher rates support USD demand).

And now tariffs re-enter this equation, because they can once again change inflation and growth — but via different, more complex legal pathways.

4) What This Means for the Euro

────────────────────────────

The euro is not just the world’s second-largest currency. It represents an economic zone that is sensitive to global trade and to any deterioration in world conditions.

If the risk of trade escalation declines, Europe usually gets some breathing room. Why?

Because Europe, overall, relies more heavily on external trade and stable supply chains. When trade wars fade, investors often view the euro more calmly, without demanding as much “risk discount.”

But the euro doesn’t trade in a vacuum. Its movement is almost always a comparison:
“Eurozone vs. United States.”

If the U.S. keeps rates higher for longer than expected, the dollar gets support. Even if Europe feels “better overall,” the yield differential can prevent EUR/USD from forming a clean, sustained uptrend.

5) Three Scenarios for EUR/USD Going Forward

────────────────────────────

Scenario A: Tariff de-escalation → softer dollar → the euro gains room 🌿

In this scenario, new tariffs are introduced only partially, delayed by procedures, or end up narrower and temporary. The market interprets that as reduced global risk.

What does it mean for EUR/USD?
The euro gets a chance to strengthen — but not as a “rocket move.” More often it’s calmer: a sequence of higher lows, steadier rebounds, and a gradual shift in balance toward the euro.

The key limitation: if U.S. inflation stays sticky, Fed policy and high yields can prevent a major dollar sell-off.

Scenario B: Tariffs return quickly → inflation risk rises → Fed stays tougher → dollar holds or strengthens 🔥

If the administration finds a workable replacement mechanism and tariffs become meaningful again, the inflation tail grows. Then the Fed is forced to stay restrictive to avoid losing control of prices.

What does it mean for EUR/USD?
The pair becomes “heavy” on the upside. Attempts for the euro to rise meet resistance because U.S. rates and yields keep pulling capital into the dollar.

Scenario C: Markets reprice U.S. fiscal risk → the dollar becomes a less obvious safe haven ⚡

This is a longer and more subtle scenario. It doesn’t start with tariff headlines — it starts when debt and deficits feel so persistent that investors demand a higher “risk payment” for holding U.S. bonds.

In that regime, the dollar can become two-directional:

• sometimes stronger during stress;

• sometimes weaker if trust in the safety of long-dated debt erodes.

For EUR/USD, that means higher volatility and more surprise moves — not simply “dollar strong/dollar weak,” but “which risk regime is the market pricing right now?”

6) My Base Forecast 🧭

────────────────────────────

Over the next several weeks and the next one to two months, it is more reasonable to expect not a clean trend, but a “range + spikes” regime.

Why?

Because the market simultaneously sees:

• signs of U.S. growth slowing (pressure on the dollar);

• inflation staying firm (support for the dollar via rates);

• uncertainty around tariffs (sharp impulses without clear direction).

So the most likely picture is “chopping” inside a range, where each new catalyst (economic data, Fed messaging, news about replacement tariff mechanisms) triggers a short burst — and then the market attempts to find balance again.

On a quarterly horizon, the fork looks like this:

• if the tariff theme becomes softer and temporarily loses force, and U.S. inflation starts cooling sustainably — the euro may gain a more durable strengthening impulse;

• if tariffs return broadly and inflation remains persistent — the dollar keeps its advantage via rates and yield, and EUR/USD becomes harder to push higher.

The simplest one-line summary:
right now, the market is deciding what is stronger — U.S. growth slowing (against the dollar) or stubborn inflation and high rates (for the dollar). And tariffs are the match that can ignite volatility at any moment.

7) What to Watch to Know Which Scenario Is Winning 🔍

────────────────────────────

To avoid arguing with the market and instead read it correctly, it’s enough to track four “dashboard panels”:

1. U.S. inflation: cooling or sticking?
   This is the main key to when the Fed can realistically ease.

2. Fed messaging: “speed” and “confidence.”
   What matters is not what the market wants, but what the Fed can afford.

3. Real tariff actions, not statements.
   If decisions become slow and targeted — that’s one world. If a workable replacement appears quickly — that’s another.

4. Long-end U.S. yields and sentiment toward U.S. debt.
   When yields rise due to economic strength, the dollar often benefits.
   When yields rise due to risk premium, the dollar can become less straightforward.

Final Thought

The Court ruling hit the “universal tariff button,” but it did not cancel the political intent to apply pressure through trade. So the main takeaway for EUR/USD is not “everything is resolved,” but “the structure of uncertainty has changed.”

In the near term, the pair will likely remain a market of meanings: growth versus inflation, politics versus procedures, the dollar-as-haven versus the dollar-as-risk. And it is at these crossroads that the next big moves are born.
