How this site is made

Sources

Every figure on the site comes from a Federal Reserve statistical series retrieved from FRED, the data service of the Federal Reserve Bank of St. Louis, through its public CSV download. The site tracks 16 series, each listed with its FRED identifier on the methodology page. One further series, FEDFUNDS (the monthly average of the effective federal funds rate), is used only on the fed funds rate history page because the tracked daily series begins in 2000. No figure is taken from a news report, a market data vendor or a model.

FRED publishes these series in different units. Each is converted to billions of dollars once, on retrieval, by a multiplier recorded per series, never inferred from the size of the numbers.

Published versus computed

Most numbers are shown exactly as published, after unit conversion. Some are computed here, and each is labelled as computed where it appears:

• 3 comparisons (spreads, shares and multiples) and 3 ratios (monetary ratios) divide one series by another only on dates both published. Nothing is interpolated or carried forward.
• Net liquidity is total assets less the Treasury General Account less the overnight reverse repo facility. It is a market convention, not an official statistic, and each weekly date is paired with the most recent daily repo figure at or before it.
• Growth rates and changes compare an observation with the last one at or before the target date. A change the history cannot support is shown as unavailable, not as zero.

How often it updates

Data pages are regenerated from FRED at most once every 24 hours. None of the series publishes more often than daily, and most are weekly or monthly, so a shorter cycle could not surface a new number. Every figure carries the date of the observation it comes from, not the date the page was built. If a retrieval fails, that figure is shown as unavailable rather than kept at its last value.

Agencies revise their history, and FRED always serves the latest version. On the 2nd of each month the site records what each series reported for the month just ended, in the monthly archive. Each record shows when it was captured, and no record is written when fewer than ten series could be retrieved, so an outage is never stored as a month.

Explainers

The 10 explainersare fixed text held in the site's source and changed only by editing it. They are written so that the prose never states a current figure, because a sentence quoting today's level is wrong within a month. Current figures sit beside the text, drawn from the data with their dates. Each explainer shows the date it was last reviewed, currently between 16 August 2026 and 16 August 2026.

The analysis archive

From August 2026 a scheduled job used a language model to draft a daily essay for the analysis section. That job was stopped in September 2026. The essays cite no series held by the site and are not the source of any figure here. They remain at their addresses so existing links keep working, but they are excluded from search indexing and from the sitemap.

The report and the weekly email

The free report is compiled from the data when it is opened. Every sentence of commentary in it is produced by a fixed threshold in the code, so no sentence can contradict the numbers beside it. The weekly email goes out on Fridays and is built from the same data.

What the site does not do

It publishes no forecasts, no price targets and no investment advice. It describes what the monetary system has done, not what it will do. Series that have been discontinued at the source (AMBSL, BASE) are listed as retired and are not charted, because they still return clean data that stops years ago.

Money

The site carries Google AdSense advertising and may carry sponsorship. Paid placements are labelled where they appear and sponsored links are marked as such. No advertiser or sponsor has any say over what is published. The disclosure page and privacy policy have the detail.
