# How quickly do stablecoin issuers publish attestations after month-end?

Publication lag across the stablecoins ReserveBeat tracks: the days between the date a reserve report covers and the date the document carries, report by report, from the reports on file.

This post measures one property of the reports behind the
[coverage board](/): how many days pass
between the date a report covers and the date the issuer's document carries.
Every date below is the document's own, read from the reports ReserveBeat has
captured for each tracked stablecoin. Nothing here is a judgment of any
issuer's solvency.

## The short answer

Across the 60 reports on file with a recorded issue date, the gap runs from
21 to 32 days. The shortest gaps are 21 days: Circle's November 2024 and
November 2025 USDC reports and the November 2025 RLUSD report. The
longest is 32 days: Circle's August 2025 USDC report, which covers
2025-08-29 and is dated 2025-09-30. USD1's April 2026 report was earlier
held with no issue date because the parser did not extract one; its parsed
record was corrected by restatement, and the document is dated 2026-05-28.

| Token | Reports on file with an issue date | Lag range, days | Latest report | Lag of the latest report, days |
|---|---|---|---|---|
| PYUSD | 8 | 23–27 | 2026-08 | 24 |
| RLUSD | 12 | 21–29 | 2026-07 | 27 |
| USD1 | 4 | 27–31 | 2026-07 | 27 |
| USDC | 23 | 21–32 | 2026-07 | 27 |
| USDG | 5 | 24–29 | 2026-07 | 26 |
| USDT | 2 | 30–31 | 2026-06 | 31 |
| USDtb | 6 | 26–28 | 2026-07 | 28 |

Each token's page lists the reports behind its row, for example
[USDC](/stablecoins/usdc) or [USDT](/stablecoins/usdt).

## July 2026: every monthly report within four days

The monthly series (PYUSD, RLUSD, USD1, USDC, USDG and USDtb; USDT reports
quarterly) all covered 2026-07-31, and their July documents are dated within
four days of each other:

- PYUSD, 2026-08-25 (25 days);
- USDG, 2026-08-26 (26 days);
- RLUSD, USD1 and USDC, 2026-08-27 (27 days);
- USDtb, 2026-08-28 (28 days).

The [attestation calendar](/attestations/calendar) lists each report on file
on the date its document carries, and each report has its own page, such as
[USDC 2026-07](/attestations/usdc/2026-07).

## Month-end is not always the last day of the month

Lag is measured from the date the report states, not from the calendar
month-end. The two are not always the same. For May 2026, the USDC, PYUSD,
RLUSD and USDG reports cover 2026-05-29, a Friday. The USD1 and USDtb
reports cover 2026-05-31.

## Some reports carry two as-of dates

The July 2026 reports for PYUSD, RLUSD, USD1, USDC and USDG each state
two [as-of dates](/learn/as-of-date): one earlier in July and the month-end
date. USDC's, for example, carries 2026-07-08 and 2026-07-31. ReserveBeat
measures lag from the later of the two.

## The quarterly series

The Tether reports on file are quarterly, and their stated scope is a
[consolidated group](/learn/consolidated-group-scope) rather than one token.
The March 2026 report covers 2026-03-31 and is dated 2026-04-30 (30 days).
The June 2026 report covers 2026-06-30 and is dated 2026-07-31 (31 days).

## Reading the same dates yourself

Every date in this post is stored with its report, and the keyless API
returns the same dates. `GET /v1/board/attestations` lists every report
on file with its `composition_as_of` and `issued_on`, and
`GET /v1/board/coverage` gives each token's `publication_lag_days` with the
basis it was measured on (`lag_basis`). The
[methodology](/methodology) covers how a report is captured before it is
parsed.

## What this does not measure

Publication lag is a fact about a document's date. It says nothing about the
reserves the document describes, or about the days between two reports. It
also does not measure when ReserveBeat captured a report, which is a separate
figure about ReserveBeat's own pipeline.

## Disclaimer

ReserveBeat renders figures from issuer-published reports and public blockchains, verbatim and at their stated scope. It is not an auditor, makes no attestation, and states no opinion on any issuer's solvency. Nothing here is investment, trading, legal, tax, or accounting advice. No figure published here is a recommendation to hold, buy, sell, or redeem any token.

Tracked tokens are subjects of public data: supply figures are read from their public Ethereum contracts, and composition figures from the issuers' own published attestation reports. No tracked issuer is a customer and none has endorsed this site.
