The ECB decision — how it moves the euro on forex
Thursday, 14:15 Central European Time. The European Central Bank announces its rate decision, and the euro barely flickers, because the number matched expectations. Half an hour later Christine Lagarde steps up to the podium, and one sentence about stubborn inflation is enough to send EUR/USD dozens of pips lower. An ECB decision is not a single moment but an hour in which the strongest move usually arrives after the number itself. Let me walk through exactly what the Governing Council sets and how to get through that hour without panic.
What the Governing Council actually sets
Monetary policy for the euro area is run by the Governing Council of the European Central Bank. It meets roughly every six weeks, eight times a year, on a calendar published well in advance. At each meeting it sets three official interest rates, but for the market one of them matters above all the others.
The three rates are the deposit facility rate, the main refinancing rate and the marginal lending rate. Historically the refinancing rate was treated as the main ECB rate. That is no longer true. Since the asset purchase programme of 2015 to 2022, euro-area banks have held large excess reserves at the ECB, so the rate paid on those reserves, the deposit facility rate, became the one that actually drives the money market. When a headline says "the ECB raised rates by a quarter point", traders are looking at the deposit rate.
Four times a year, in March, June, September and December, the decision comes with macroeconomic projections from ECB staff: forecasts for inflation, growth and unemployment over the coming years. This is the counterpart to what the Federal Reserve does at its own decision through the dot plot, although the ECB does not show individual votes, only a collective forecast. Traders compare the new projection with the previous one: a raised inflation path is a hawkish signal, a lowered one is dovish.
The timing of a meeting day
For a European trader the rhythm of the day is convenient, because everything happens in Central European Time. The decision lands at 14:15, and the president's press conference begins at 14:45 and usually runs for about an hour.
It typically unfolds like this. Just before 14:15 the market is artificially calm, because nobody wants to hold a large position at the moment of release. At 14:15 the statement drops, and the first reaction plays out on the number itself and on the short accompanying text. Then come fifteen or so minutes of relative quiet, while analysts read the statement word by word. At 14:45 Christine Lagarde starts speaking, and it is the tone of her remarks that often triggers a second, larger wave. You will recognise the same mechanism at other central banks once you learn to read the economic calendar in advance.
Why the euro reacts to the gap, not the decision
Here is the key idea: the euro reacts not to the decision as such, but to the gap between what the ECB announced and what the market expected. And it expects far in advance. Governing Council members communicate intensely in the weeks before a meeting. Speeches during the so-called quiet period, the week before the decision, are forbidden, but earlier the policymakers regularly steer expectations. By meeting day a large share of the information is already in the price.
That gives a simple split of reactions. The hawkish and dovish vocabulary is worth knowing before every meeting. A hawkish surprise, meaning higher rates or firmer guidance on future policy, usually strengthens the euro and lifts EUR/USD, because higher yields attract capital. A dovish surprise, meaning a signal of cuts or a softer statement, weakens the euro and pushes the pair down. When the decision and the tone fully match expectations, the rate barely moves.

The lesson from this example is instructive: the central bank raised rates and the currency weakened, because the market heard that this was probably the last move in the cycle. What counts is the path, not the single decision.
„Of all the macroeconomic releases, none move the currency market as powerfully as central-bank interest-rate decisions — it is the interest-rate differentials and their expected path that drive exchange rates." — Kathy Lien, Day Trading and Swing Trading the Currency Market, Wiley, 2016.
Why the press conference can outweigh the decision
Since the number itself is usually priced in, the real source of volatility is what happens afterwards. The statement delivers the first batch of information, but it is the president's press conference that adds the hint about future policy. Christine Lagarde first reads a prepared statement and then takes questions from journalists, and it is often in that second part that a sentence lands which reverses the first reaction to the statement.
The market listens less to the substance than to the nuance: did the tone soften or harden compared with last time? An experienced trader looks for specific phrases. Saying that inflation remains too high sounds hawkish. Insisting that decisions will depend on incoming data is neutral and signals a wait-and-see stance. Noting that disinflation is making progress sounds dovish. Every change in wording from the previous conference is a signal, because the president chooses her words deliberately. How to set an ECB decision in the wider context of the other banks is something I lay out in an overview of the major central banks.
Scale matters too. EUR/USD is the most liquid currency pair in the world and the main vehicle through which the reaction to the ECB plays out. The effect of a meeting is also visible on euro crosses such as EUR/GBP or EUR/PLN, though there the move tends to be less violent and more dependent on events on the other side of the pair.
What to do at the next meeting
- Check the calendar and the consensus the day before. Open the official Governing Council meeting calendar and note the date of the next decision. Then establish which rate move the market is pricing as its base case, and whether the meeting includes fresh macroeconomic projections — those usually amplify the reaction.
- Cut your exposure before 14:15. If you have less than six months of experience, close open positions on euro pairs a dozen or so minutes before the statement. You lose two hours of market, but you remove the risk of a violent two-way swing that takes out your stop loss before you can react.
- Wait for the conference to end before re-entering. Do not open a new position in the first minutes after the decision. Let the market work through to the end of the president's remarks, and only then judge whether the tone was hawkish or dovish and whether the move has follow-through.
- Log the reaction in your journal. Afterwards, write down what the market had priced, what the ECB announced and how EUR/USD behaved. After a handful of these meetings you will start to tell the difference between a genuine surprise and noise that retraces within a quarter of an hour.

Frequently asked
How does the ECB differ from the Federal Reserve?
There are three main differences. The first is the mandate: the Federal Reserve has a dual goal of stable prices and full employment, while the ECB's overriding objective is inflation of two percent over the medium term. The second is the area of operation: the ECB runs a single policy for twenty euro-area economies in very different shape, from Germany to Greece, so reaching a common decision can be harder. The third is communication: the Fed publishes a dot plot with individual members' forecasts, while the ECB shows collective staff projections four times a year. For a trader that means ECB signals more often have to be read from the tone of the conference than from hard numbers.
Why does the market watch the deposit rate rather than the refinancing rate?
The deposit rate is the interest the ECB pays commercial banks on the excess reserves they hold in their account at the central bank. The refinancing rate is the cost at which banks borrow from the ECB. For decades the latter was treated as the main rate, but the asset purchase programme of 2015 to 2022 flooded the system with money and euro-area banks began holding constant, very large excess reserves at the ECB. In that world the deposit rate became the one that actually sets the cost of money in the market, so traders treat it as the real ECB rate. When the media write about the ECB raising or cutting rates, they almost always mean the deposit rate, because it is the one that feeds through to bonds, deposits and exchange rates.
How does the Christine Lagarde press conference affect EUR/USD?
The conference starts at 14:45 and usually runs for about an hour. The president first reads a prepared statement and then takes questions from journalists, and it is that second part that tends to be the most volatile. A trader looks for specific phrases and for a change in tone from last time: saying that inflation remains too high sounds hawkish, while noting that disinflation is making progress sounds dovish. The answer to a question about future rate moves matters too, because it reveals the council's stance for the coming weeks. A single sentence can reverse the first reaction to the statement and move EUR/USD dozens of pips within minutes, which is why experienced traders watch the conference live rather than acting right after the decision itself.
Does the ECB decision affect the Polish zloty too?
Yes, though more indirectly than the euro. The euro area is Poland's main trading partner, so the ECB's stance feeds into sentiment toward the region's currencies, including the zloty. It shows up most clearly on the EUR/PLN rate: a hawkish ECB that strengthens the euro can lift this pair, meaning the zloty weakens against the common currency. An interest-rate differential channel works here too, because the relationship between euro-area rates and the rates of the National Bank of Poland affects how attractive it is to hold the zloty. For a Polish trader that means ECB meetings deserve almost as much attention as domestic decisions, especially when trading pairs that involve the euro or the zloty, because the reaction often spreads beyond EUR/USD itself.
