Crypto Custody SEC Filings (SEC EDGAR)
Monthly SEC filings mentioning 'crypto custody' - the regulated infrastructure layer enabling institutional flows. The open month is month-to-date and partial; prior points are closed-month totals. Coverage starts April 2021 (term ingestion start date).
What is it?
Custody is the regulated infrastructure that lets institutions hold crypto. Without qualified custodians (Coinbase Custody, BitGo Trust, Fidelity Digital Assets, BNY Mellon Custody), institutional capital cannot legally enter crypto. This filings count traces the maturation of this critical institutional layer.
How to read
Single line, logarithmic scale: each point counts SEC filings containing the searched mention, without measuring assets in custody. The open month is month-to-date and partial; prior points are closed-month totals. Changes can be compared with dated events without automatically attributing a regulatory cause.
Key zones
Compare filing counts across periods and distinguish closed months from the partial month. SAB 121 and SAB 122 are dated accounting references, not volume thresholds or evidence of a sustained break in this series.
What to observe
Custody filings leading bitcoin filings by 6 months = infrastructure-first institutional setup phase. Custody flat while Bitcoin filings rise = late-stage institutional cycle. Custody collapsing = regulatory crackdown.
Historical context
The SAB 121 text is dated March 31, 2022, effective April 11, 2022. It describes the accounting treatment of obligations to safeguard crypto-assets for others. SAB 122, dated January 23, 2025 and effective January 30, 2025, rescinds the Topic 5.FF guidance introduced by SAB 121. These dates do not establish a causal effect on the number of filings containing the searched mention.
Expert notes
SAB bulletins express SEC staff interpretations. Rescinding Topic 5.FF does not remove other applicable accounting and disclosure requirements. The chronology does not establish an increase in filing counts, assets in custody or institutional flows.
Common mistakes to avoid
Custody filings = AUM in custody ❌. Filings measure regulatory attention, not assets under custody. Coinbase Custody AUM data is in their 10-Q quarterly reports (not in this filings count).
