U.S. Agencies Jockey for Legal Custody of Trump's Strategic Bitcoin Reserve

President Trump's plan to launch a Strategic Bitcoin Reserve (SBR) is running into a Washington problem: deciding which federal entity will legally hold and manage the Bitcoin. Bloomberg reports senior officials are still negotiating whether the Treasury Department, the Commerce Department, or another office should serve as custodian for government-controlled BTC. The dispute comes as the U.S. already holds a sizable trove of seized and forfeited Bitcoin. BitcoinTreasuries estimates federal holdings at 328,372 BTC worth about $20.7 billion as of July 7, making the United States the largest known government holder. Converting that balance into a formal reserve would set a high-profile precedent for how Washington treats digital assets. At issue is legal authority and custody mechanics, not market strategy. Officials are weighing whether existing statutes give Treasury clear power to treat a volatile crypto asset as a federal reserve asset, how forfeited coins should be stored, and what governance rules should apply to a reserve built from seized BTC. Trump's March 2025 executive order directed the Treasury secretary to establish an office to manage the SBR. It specified that the reserve would consist of Bitcoin forfeited through criminal and civil proceedings, including assets already in federal custody, and stated that BTC placed in the reserve should be held as reserve assets rather than sold. The order also called for a Treasury review of legal and investment issues, including where accounts should be housed and whether new legislation is required. Even though Treasury is named in the order, Commerce has been discussed as an alternative home. The Justice Department's Office of Legal Counsel is working with both agencies to design a structure that can withstand legal scrutiny, underscoring that control of the reserve remains unsettled. On Capitol Hill, lawmakers have floated bills to formalize the concept. The American Reserve Modernization Act would create a Treasury-run Bitcoin reserve, impose a 20-year holding period, require audits and proof-of-reserve reporting, and direct reviews of budget-neutral ways to acquire Bitcoin. No federal legislation has been enacted, leaving the executive branch to resolve custody and authority questions internally. A White House spokesperson told CoinDesk the administration "continues to evaluate the best structure" for the Strategic Bitcoin Reserve and a broader U.S. Digital Asset Stockpile. White House crypto adviser Patrick Witt told crypto.news in May that officials had made legal and custody "breakthroughs" and that an announcement was expected. The latest reporting indicates the framework is still under active review. The U.S. already has a de facto Bitcoin reserve on paper. Turning it into a durable program now hinges on settling who can legally control seized BTC, how it will be stored, and how oversight and governance will work—not on buying additional Bitcoin.
