Euro Fundamentals (EUR)

Euro fundamentals start with what the euro stands opposite. The euro is on one side of 28.9 percent of all currency trades, second only to the dollar (BIS Triennial Survey, April 2025), and EUR/USD is the market’s main way to trade a view on the dollar. So a euro move is often a dollar move in reverse.

One currency, many economies

The euro is one currency over many economies, and over many governments that each issue their own debt. That gives it deep markets and the second-largest share of the world’s foreign exchange reserves after the dollar: 20.6 percent in the second quarter of 2026 (IMF COFER). It also gives it a weak point the other majors do not share in the same form.

Traders who want to sell the dollar often buy EUR/USD, so the euro can rally on weak US data rather than strong European data. Before crediting the euro with strength, check whether the move is really the dollar’s: see US Dollar Fundamentals (USD). Why a pair always moves on both sides is in Currency Pairs and Relative Pricing.

The ECB against the Fed

The anchor is the European Central Bank. It aims for “2% inflation over the medium term” and considers deviations either side “equally undesirable” (ECB strategy). Each decision is on ECB Interest Rate Decision.

What moves the euro is the ECB’s expected path against the Fed’s. The gap is on Interest rate differential by currency pair, after inflation on Real interest rates by currency, and the pair itself on EUR/USD fundamentals. The euro can rise on an ECB meeting that leaves rates unchanged, if the message lifts the expected path against the Fed’s.

The euro’s carry has changed over its history. The ECB’s deposit facility rate was below zero from June 2014 until July 2022 (ECB key interest rates). In that period the euro was cheap to borrow and at times funded carry trades. Whether the euro pays or costs you to hold depends on where the two central banks are in their cycles.

The data that matters

• Euro Area Inflation Rate (HICP) is the measure behind the ECB’s target. Inflation above target tends to lift the expected path and support the euro.
• Euro Area Manufacturing PMI carries extra weight because the area’s economy leans on manufacturing and trade. The surveys often show a turn in growth before GDP does.
• Euro Area GDP Growth Rate frames relative growth. The euro tends to struggle when the area lags the US.

What moves the euro is the result against the forecast, not the number itself.

Energy and fragmentation, with 2022 as the example

The first wildcard is energy. The euro area imports much of its energy, so an energy price shock sends income abroad and tends to weaken the euro. In 2022 the ECB’s reference rate for EUR/USD was below parity on most days from late August to early November, with a low of 0.9565 on 28 September (ECB reference rates). The rate gap worked against the euro at the same time: the Fed began raising its target range in March 2022 (Federal Reserve), while the ECB’s deposit rate only returned to zero in July.

The second is fragmentation. Under stress, the borrowing costs of weaker member states can rise much faster than those of stronger ones. That can weigh on the euro and limit how far the ECB is willing to tighten. On 21 July 2022 the ECB announced the Transmission Protection Instrument: bond purchases “not restricted ex ante” against “unwarranted, disorderly market dynamics” (ECB press release). A country has to meet criteria to qualify, among them compliance with the EU fiscal framework and a sustainable public debt, so traders still watch the spreads between member states.

Crosses and positioning

Beyond EUR/USD, the euro’s crosses read the ECB against each peer: EUR/GBP against the Bank of England, EUR/JPY against the Bank of Japan. EUR/JPY also carries risk sentiment, because the yen tends to strengthen when markets turn defensive (Japanese Yen Fundamentals (JPY)). For the franc, see Swiss Franc Fundamentals (CHF).

The Euro COT report shows how leveraged funds lean in euro futures, from the CFTC’s Traders in Financial Futures report (CFTC). Because the euro is the default vehicle for dollar views, euro positioning often mirrors sentiment on the dollar.

How to put it together

• Is this a euro move or a dollar move? Check whether US or euro area news is driving.
• Is the ECB’s expected path moving against the Fed’s?
• What is energy doing? A shock to the terms of trade can override the rate story.
• Are the spreads between member states calm or widening?

Do not mistake a falling dollar for a strong euro: check that the euro’s own path is improving before you treat its strength as real.
