What happened

Sponsors filed the American Reserve Modernization Act on Thursday in Washington, a bill that would require the Treasury to build and maintain a Strategic Bitcoin Reserve for no less than 20 years, Decrypt reported. The legislation, abbreviated ARMA, lifts the reserve concept out of the realm of executive directive and tries to fix it in statute. That is the substantive change. A reserve created by executive order can be unwound by the next executive order. A reserve created by act of Congress requires Congress to undo it.

The text, as described, directs the Treasury to create the reserve, hold it for a minimum of two decades, and treat the holdings as a long-duration asset. Decrypt's report frames ARMA as the statutory follow-on to the executive-order framework that has shaped U.S. bitcoin reserve policy since early 2025. The bill does not, on the initial reading, mandate a fresh open-market purchase program; it locks in the holding posture and sets the floor at 20 years.

Why it matters

This is the difference between a policy and a law. An executive order is a signal. A statute is a constraint. If ARMA passes in anything close to its filed form, a future Treasury Secretary cannot wake up in 2029 and sell the reserve to plug a budget gap without going back to Congress. That changes the way professional allocators have to model U.S. sovereign bitcoin exposure.

It also resets the diplomatic conversation. Several jurisdictions have floated their own reserve frameworks since the U.S. executive order took effect. Most are non-binding. A 20-year statutory floor in Washington pressures peers in the G7 and the BRICS bloc to clarify their own positions, either by matching the commitment or explicitly rejecting it. The headline looks bullish. The flow picture is more nuanced: codification is a slow-motion event, not a same-day catalyst.
