Events that can reprice a market, and how to read them
A catalyst is a scheduled or unscheduled event that can change the evidence. This note explains the main types. It is not a diary of upcoming dates.
Key points
- A release measures something specific. The headline is not the whole release.
- Markets respond to the surprise relative to what was already priced, which this page does not observe live.
- Dates belong on an official schedule. They are not typed in here from memory.
What is going on
The events that most often force a repricing are economic releases, central-bank decisions, company results, commodity inventory and production news, and political or regulatory decisions. Each has an official home: a statistics office, a central bank, a company filing, a commodity exchange or a legislature. The IMF and the BIS discuss how those events sit inside a broader policy and financial-conditions story. WiT Markets does not currently connect a live calendar, so this note stays at the level of the event type.
Why it matters
Interpretation fails in familiar ways. A single inflation print is treated as a new regime. A payrolls figure is read without the participation rate or revisions. An earnings beat is detached from guidance. An inventory draw is detached from the reason for the draw. A policy sentence is quoted without the decision that accompanied it. The catalyst section on the outlook page lists those checks beside each event type.
What to watch
Use the publisher’s own release, including the revision and the definition. For policy, read the decision, the statement and, when they exist, the minutes. For companies, read the filing, not only the headline earnings-per-share figure. For commodities, read stocks and production together. For politics, separate a proposal from a statute.
Risks
Events cluster. A central-bank day can coincide with an inflation print. Liquidity is often thinner around the release, which can exaggerate the first move. This framework does not say which event is next, or what the surprise will be.
