Federal Reserve H.10 Foreign Exchange Rate Data Correction: August 3, 2026 Figures Restored

Federal Reserve H.10 Foreign Exchange Rate Data Correction: August 3, 2026 Figures Restored (Sovereign Tax Atlas Desk Note, 2026-10-28) — This briefing summarizes the supplied source material at http://www.federalreserve.gov/feeds/H10.html#3940. Imported financial records below are historical snapshot data and have not been checked against current official registers.

H.10 Data Correction: All Currencies and Dollar Indexes Affected#

The Federal Reserve's H.10 Foreign Exchange Rates release published on August 10, 2026 contained incorrect data for all currencies and all dollar indexes for the reference date of August 3, 2026 (Source: Federal Reserve H.10 Feed, 2026-08-12). The error affected every currency series and every dollar index included in that release — no individual series was spared. Users who downloaded or cited the August 10, 2026 H.10 release should treat all August 3, 2026 figures from that snapshot as unreliable and replace them with the corrected values.

Correction Timeline and Scope#

The Federal Reserve resolved the technical issue and published corrected data on August 12, 2026 — 2 calendar days after the erroneous August 10, 2026 release (Source: Federal Reserve H.10 Feed, 2026-08-12). The correction covered 2 distinct data assets: (1) the H.10 statistical release itself, and (2) the corresponding entries in the Federal Reserve's Data Download Program (DDP). Any automated pipeline or institutional database that ingested the August 10, 2026 H.10 release must be re-pulled against the August 12, 2026 corrected version to ensure data integrity.

Implications for Data Users and Compliance Records#

Institutions relying on Federal Reserve H.10 exchange rate data for valuation, transfer pricing, or regulatory reporting must verify that their records reflect the August 12, 2026 corrected release rather than the August 10, 2026 erroneous release (Source: Federal Reserve H.10 Feed, 2026-08-12). The affected reference date is August 3, 2026 only; no other dates within the H.10 series are noted as impacted by this technical issue. The Data Download Program was updated in parallel with the H.10 release correction, providing a single authoritative source for re-verification. Note: the underlying license and publication authority information for the H.10 series is drawn from the imported source snapshot and has not been independently verified line-by-line.

FAQ#

Which specific currencies were affected?#

The Federal Reserve's notice states that all currencies included in the August 10, 2026 H.10 release carried incorrect values for the August 3, 2026 reference date (Source: Federal Reserve H.10 Feed, 2026-08-12). No individual currency series was identified as unaffected; the error was systemic across the entire release.

Was the Data Download Program also corrected?#

Yes. The Federal Reserve explicitly confirmed that the corresponding entries in the Data Download Program were corrected on August 12, 2026, in parallel with the H.10 release correction (Source: Federal Reserve H.10 Feed, 2026-08-12). Users who access H.10 data via the DDP API or bulk download should re-pull August 3, 2026 data to obtain the corrected figures.

Do dates other than August 3, 2026 require re-verification?#

Based on the Federal Reserve's published notice, only the August 3, 2026 reference date was identified as containing incorrect data in the August 10, 2026 H.10 release (Source: Federal Reserve H.10 Feed, 2026-08-12). No other reference dates within the H.10 series were cited as affected by this technical issue. However, institutions with strict data governance policies should confirm directly with the Federal Reserve if broader validation is required.
