What Is an Economic Calendar

An economic calendar is a timetable of scheduled data releases, central bank decisions and official commentary that have a history of moving prices, sorted by date, time and country. Each row carries the previous reading, the consensus forecast and, once the embargo lifts, the actual figure. It is a planning tool and nothing more. It tells you when something is scheduled to happen. It does not tell you what the number will be, and it does not tell you which way price will go.

One row, decoded: USD, 13:30, CPI year on year

A typical entry reads USD | 13:30 | CPI y/y | Previous 3.2% | Forecast 3.1% with a three-star impact marker beside it. Four separate pieces of information sit in that line, and each one changes a different decision.

• The currency tag. USD means the release is about the United States, so it prices the dollar first and everything quoted against the dollar second. If you are long EUR/USD, short GBP/USD or holding gold, a USD row is your row whether you were watching it or not.
• The time. Displayed in whichever zone you selected, converted from the publishing agency's local time. This is the field people get wrong twice a year, when clocks in Europe and North America shift on different dates.
• The impact marker. One, two or three stars, or the words low, medium and high. It is a historical average of past reactions, not a forecast of the next one.
• The three numbers. Previous, forecast and actual. The third appears at the scheduled second and not one tick before.

Now let the actual land at 3.4% against that 3.1% forecast. That is a three-tenths upside surprise on the most closely watched inflation series in the world. In the following sixty seconds EUR/USD can travel 60 to 90 pips, a pair that normally quotes a 0.8 pip spread can quote 6 to 10, and a 0.5 lot position moving 60 pips against you is roughly $300 gone while you are still reading the headline. The pip calculator turns that into your own account currency in a few seconds, and the time to do it is before the release, not after.

The forecast column is the one that moves price

Most people read the actual figure and ask whether it is good or bad. Markets do not price it that way. The consensus forecast has been public for days by the time the release lands, and positions already reflect it. What moves price is the distance between forecast and actual, in the direction of the surprise.

Run that same 3.4% print against a different forecast and the reaction inverts. Against a 3.1% forecast it is a hot number: expected rate cuts get pushed back, yields rise, the dollar rises with them. Against a 3.5% forecast the identical 3.4% is a cool number, and the dollar falls. Same data, opposite trade. That is why a headline reading "inflation rises again" can sit directly above a chart showing the currency dropping, and why comparing the actual only to the previous reading will mislead you roughly half the time.
