Calendar impact labels are unreliable, treat them with suspicion
Posted: Sat Oct 31, 2026 6:52 am
Economic calendars colour events red, orange, or yellow, but the labels are generic. They reflect average historical impact, not what is likely today.
A usually minor release can become a big one when the market is focused on it. Inflation data matters little when a central bank is relaxed, and enormously when it is deciding on a rate move. Retail sales data barely registers in calm periods and shakes everything in uncertain ones.
The label also ignores the pair. A Japanese release rated low might still move USDJPY and cross pairs noticeably.
A better method is building a personal list based on past reactions. Reviewing the last six months of trades and noting which events produced slippage, wide spreads, or sudden moves gives a tailored guide.
Expectations matter too. A release close to the forecast produces little reaction, while a big miss makes a minor event important.
Is a personal event list maintained, or is the calendar's rating trusted as given?
