The Economic Calendar: Which Reports Move Markets

Your investing plan sets aside $200 a month. Then a headline says: “Inflation cooled.” Did prices fall, or did inflation come in below forecasts?

The headline alone answers neither. A slower increase can still be a bigger increase than expected.

An economic release calendar lists when reports and policy announcements arrive. Your task is to check whether a release changes an assumption behind your plan. Start with one dated US inflation report and finish with a statement you can support.

Choose what deserves attention

Start with jobs, CPI/PCE inflation and Fed decisions; add GDP, business surveys and retail sales when they bear on your question. Consumer confidence adds context. Market concerns and unexpected results can change that order.

• ISM is the Institute for Supply Management. Its manufacturing purchasing managers' index (PMI) is a diffusion index: it measures how widespread reported changes are, rather than their dollar size. At 50 it is neutral; above signals manufacturing expansion, below contraction.
• Retail sales covers retail and food-service spending in dollars, without adjusting for price changes. It adjusts for seasonal and calendar effects and covers only part of consumer spending.
• Consumer confidence surveys ask how people see present conditions and the future. An opinion is not a purchase.

Attention is a budget, too. If you own diversified funds, you can finish this check without researching companies.

Verify the clock and the source

The timeline gives a rough reading rhythm. PCE price data arrive in BEA's Personal Income and Outlays report. GDP estimates and Federal Open Market Committee (FOMC) decisions need their own date checks.

1. Check the source and clock. The BLS schedule lists jobs and CPI releases in Eastern Time. Allow for daylight saving when converting to your time zone. Holidays and delays can move dates.
2. Match the period and units. The release reference period is the span the number describes, such as a month or quarter. A June release can describe May. Check the measure, units, monthly versus annual change, and seasonal adjustment.
3. Keep the release vintage. These are the estimates available on that date. Separate revisions to earlier periods from the new reading. To understand an old headline, use the numbers available then.

Budget and tax announcements run on a different clock. Check when a measure was announced and when it takes effect; a proposal, a law and actual spending are three different things.

Check the May 2024 inflation release

Open the BLS CPI release dated June 12, 2024. Before reading on, find the release time, the month covered, and Table A's “All items less food and energy” row. Use the seasonally adjusted monthly columns for April and May.

The answers are 8:30 a.m. Eastern Time on June 12 and a May 2024 reference month. The row is core CPI-U: the index for urban consumers, excluding food and energy.

Source: BLS's June 12, 2024 release, seasonally adjusted monthly CPI-U readings; pp means percentage points, not percent.

Choose every statement these inputs support:

• Core inflation slowed from April to May.
• Core prices fell in May.
• The May reading exceeded forecasters' estimate.

Only the first is supported. The rate changed by 0.2% − 0.3% = −0.1 percentage point. The core price index still rose: a smaller rise is still a rise.

The third needs a consensus forecast: a named survey's summary of private forecasts collected before release. It is an expectation, not an official promise. April's reading cannot stand in for it.

Match the measure, period and units. For practice, try two invented forecasts for May's monthly core reading. A 0.1% forecast gives 0.2% − 0.1% = +0.1 percentage point. A 0.3% forecast gives 0.2% − 0.3% = −0.1 point.

Slower than last month and higher than expected can both be true.

Finish with what you know

A finished observation can be this short:

May's monthly core inflation slowed. The forecast is missing here, so I cannot tell whether it was a surprise. These numbers alone do not tell me how a stock responded.

One useful next check is a forecast published before the release for May's monthly, seasonally adjusted core CPI. Keep the survey provider and date with it. Then you can tell whether +0.2% was above, below or equal to expectations.

For an optional company check, take Harbor Coffee, our fictional coffee business. The type of loan rate and its reset or refinancing date determine when the bill can change. This case supplies neither the terms nor a new borrowing quote. Without them, you cannot turn the rate news into an earnings estimate.

Missing evidence is a result you can use. Your check is complete with a supported statement, a missing input and a reason to seek it. If this release changes no assumption in your plan, recording that is also a finished result.

Keep deeper checks optional

Let the missing input choose any deeper check:

• Broader weakness. Use the business cycle to compare output and jobs; recession dating separates the economic turn from its later confirmation. The yield curve adds a signal about future risk.
• Fed holdings. Use QE and QT when the news concerns bond purchases or a shrinking Fed portfolio rather than just a rate decision.
• Currency and costs. Trace foreign receipts and bills through exchange rates, or raw-material prices through commodity exposure. Each needs evidence about the business involved.

A simple investing plan can be complete without following every branch.

In short

• Check who released the number, when it arrived and which period it describes.
• A lower inflation rate can still mean higher prices.
• Compare with the previous reading for change, and with the pre-release forecast for surprise.
• Keep reported readings, calculations and assumptions separate; missing inputs are not numbers to invent.
• A calendar schedules information. It does not require a trade or a change to planned contributions or withdrawals.
