Economic Events and Headlines: Volatility, Not Instructions

Before you read: Trading Sessions and Costs: Hours, Fees and Slippage

What you will learn

• What an economic calendar lists, and the main kinds of scheduled events: economic releases, earnings reports and central bank meetings.
• How scheduled events and unexpected headlines can change volatility and liquidity.
• Why a headline is information to be understood, not an instruction to act.

Why do scheduled events matter to a chart?

If everyone knows a report is coming at a set time, why can the market still move sharply when it arrives?

Prices reflect what participants collectively expect. A scheduled report replaces expectations with a published number. If the number differs from what many participants expected, they may reassess quickly, and prices can move further and faster than usual for a short time. Even when the number is close to expectations, the minutes around a release can look different from the rest of the session because many participants step back beforehand and return afterwards.

What is an economic calendar?

Before a session, how would you know what is scheduled?

An economic calendar lists scheduled releases with their date, time, the period they cover, and often a consensus estimate and the previous value. Government agencies and central banks publish their own release schedules, and many brokers and data sites compile them in one place.

Common types of scheduled events:

• Inflation data, such as the Consumer Price Index and Producer Price Index from the US Bureau of Labor Statistics (BLS release calendar).
• Employment data, such as the monthly Employment Situation (jobs) report from the Bureau of Labor Statistics and weekly unemployment insurance claims from the Department of Labor.
• Growth and activity data, such as GDP from the Bureau of Economic Analysis, retail sales from the Census Bureau, and business surveys.
• Central bank decisions, statements, meeting minutes and speeches, which can affect interest-rate expectations. In the US, the Federal Open Market Committee holds eight regularly scheduled meetings a year and releases minutes three weeks after each policy decision (FOMC calendar).
• Earnings reports, in which listed companies publish results, usually before the open or after the close for US stocks. Large companies’ reports can affect related stocks, sectors and indexes.

Times vary by country and agency, and schedules change around holidays and occasionally for other reasons. In the US, the CPI, PPI, jobs report, GDP and retail sales releases are listed at 8:30 a.m. Eastern Time on the agencies’ calendars. During a 2025 lapse in federal funding, BLS delayed some releases and did not publish its October 2025 jobs and CPI reports (BLS notice).

How can events change volatility and liquidity?

In the seconds before a major release, would you expect the order book to look deeper or thinner?

Patterns that traders commonly describe around scheduled events, which vary by market and by event:

• Before the release: some participants pull resting orders or reduce positions, so the order book can thin out and spreads can widen (how markets work).
• At the release: prices can jump several steps at once, sometimes with gaps between trades. Stop orders triggered in that moment may fill well away from their stop prices (order types and execution).
• After the release: activity and trading volume often rise as participants reassess. Price can swing in both directions before settling, or keep moving.

The size of these effects is not fixed. It depends on how far the result differs from expectations, on what else is happening, and on the market. These lessons do not claim any typical move size.

What about unscheduled headlines?

How do you weigh a headline you cannot verify?

Not all news is scheduled. Geopolitical events, policy announcements, company news, natural disasters and technical outages can arrive at any time. Unscheduled headlines can be incomplete, wrong, or later corrected, and early reports on social media are especially prone to this. A market can react sharply to a headline and then reverse when more information appears.

Why are headlines not instructions?

When a headline says a market “should” rise, whose opinion is that?

News coverage often explains price moves after the fact (“stocks fell on rate worries”), as if one cause were known. In reality many participants act for many reasons, and the explanation is often a best guess. Commentary that says what a market “will” or “should” do is opinion, however confident it sounds.

Some questions that help separate information from instruction:

• What exactly was released or reported, and by whom?
• How does it compare with the expectation before the release?
• Is this a primary source, such as the agency itself, or someone’s summary?
• Is the headline describing a fact, or predicting a market reaction?

How do events fit into a trading plan?

What could you decide before the event, so that you are not deciding during it?

Many traders check the calendar during preparation and note scheduled events in their trading plan. Some choose not to hold positions or place orders around certain releases; others focus on those periods. These lessons do not suggest either approach. The descriptive point is that event times are known in advance and can be part of a plan rather than a surprise.

What this does not tell you about economic events

• How any market will react to any release.
• Which events matter most for a particular product at a particular time.
• Whether to trade, or not trade, around news.

Reflect on these; there is no score.

1. Name three types of scheduled events that appear on an economic calendar. Hint: inflation, employment, central banks, earnings.
2. Why might spreads widen in the seconds before a major release? Hint: resting orders pulled.
3. Rewrite the headline “Stocks set to soar on jobs data” as a factual statement. Hint: what was released, and how it compared with expectations.
4. Why can a stop order fill far from its stop price at a release time? Hint: gaps between trades.
