US Treasury Drafts Bitcoin Custody Rules as Reserve Size Stays Unclear

The US Treasury is developing a Bitcoin custody framework that would permit two operating models simultaneously: self-custody, in which the government holds the private keys itself, and third-party custody, in which a specialized outside firm safeguards those keys on its behalf. The initiative arrives while the size of the government's own holdings remains contested, with estimates ranging from approximately 198,000 BTC to more than 328,000 BTC.

The gap matters. At the low end, the figure excludes coins tied up in pending litigation; at the high end, those coins are counted. Until agencies settle on a reliable inventory, both numbers will continue to circulate, and any custody framework built on an uncertain asset count inherits that uncertainty.

What created the framework's mandate?

The custody work traces back to March 6, 2025, when Executive Order 14233 established the Strategic Bitcoin Reserve. The order authorizes the Treasury to manage forfeited Bitcoin and bars routine sales of those holdings, permitting disposals only in limited circumstances.

The reserve's composition is enforcement-driven, not market-driven. Its coins come predominantly from civil and criminal asset forfeitures — assets obtained through law enforcement actions rather than purchases on the open market. The government is, in effect, a holder by default.

The original executive order gave agencies 30 days to review and report the Bitcoin they controlled. The current effort links to a follow-up review aimed at improving the accuracy of those initial figures. The existence of a second review is itself a signal: the first count did not settle the question.

Why cold wallet security is part of the conversation

The custody push lands as the industry scrutinizes cold wallet practices. A cold wallet stores private keys offline, typically on a dedicated hardware device, to keep them beyond the reach of internet-based attacks. Recent high-profile firmware issues in hardware wallets have complicated that reputation and pushed custodial practices back into the spotlight.

The Treasury initiative is operational in focus. It is not framed as a direct response to any outside breach — a distinction worth noting, though the framing leaves open how much the firmware episodes influenced internal deliberations.

What remains undecided?

Patrick Witt, a senior crypto policy advisor, has indicated that discussions are ongoing about whether to publicly disclose the government's specific holdings. That decision has not been made.

Witt is also exploring possible routes for acquiring more Bitcoin. Those options require further legal analysis before anything moves forward, and no consensus exists yet on how to approach them. The reserve today is built entirely from forfeitures; any expansion through other means would need a legal foundation that is still under study.

The takeaway in plain words: the government can say how it plans to hold the coins, but it cannot yet say how many it holds, whether it will disclose them, or whether it may buy more.

What does the no-sales rule change?

The no-routine-sales provision in EO 14233 alters a long-standing market concern. Historically, large government auctions of seized coins raised worries about supply hitting the market at once. A reserve that holds rather than sells changes that calculus for forfeited inventory.

The door is not fully shut, however. The order's limited exceptions mean disposals remain possible in defined circumstances, and the boundaries of those exceptions have not been tested publicly.

The accuracy review may prove just as consequential as the custody framework itself. Until agencies produce a defensible count, the range between roughly 198,000 BTC and more than 328,000 BTC will keep circulating, and pending litigation will continue to drive much of that variance.

What comes next

The immediate watch points are procedural. The follow-up holdings review must conclude before the reserve's size can be stated with confidence; the disclosure question remains open pending a decision; and any acquisition pathway requires legal analysis that has not concluded. The custody framework, the inventory count and the acquisition question each carry their own timeline, and none has a public deadline attached — a gap that will test how quickly the Treasury converts policy language into operational practice.
