Sources and method

Where the Market Brief’s numbers come from, and how to read them.

Reading the figures

Each issue uses the latest available observation for its reporting week. The date beside a price is the source’s observation period, which can be earlier than the issue date. Weekly, monthly and auction series move on different schedules.

Changes compare the displayed observation with its previous available observation. A year-over-year comparison is labeled separately. Missing observations stay blank; they are never replaced with zero or an estimated price.

Public data is loaded through narduk-data releases. Publisher revisions and publication delays can change what is available. Henry Hub is an EIA spot series; Mid-C is ICE via EIA.

Manual quotes (AAA daily diesel, broker LCFS) are entered by PACC from the named source. These quotes carry their own source and as-of date and are separate from the public series below.
