US BTC reserve bill adds 20-year lock

TLDR

US lawmakers have proposed locking federal Bitcoin into a strategic reserve that cannot be touched for at least 20 years.

1. The American Reserve Modernization Act would create a Strategic Bitcoin Reserve and bar selling reserve BTC for two decades except in narrow cases.
2. The bill could eventually cover up to around 1 million BTC and would halt the current practice of auctioning seized coins, potentially tightening long term liquid supply.
3. It is still only a proposal that must pass both chambers and be signed, so market impact depends on politics, implementation details, and the pace of any future purchases.

Deep Dive

1. What The Bill Actually Does

The American Reserve Modernization Act of 2026 (ARMA) would formally create a Strategic Bitcoin Reserve inside the US Treasury and a separate Digital Asset Stockpile for non Bitcoin holdings, like seized ETH or stablecoins. One detailed summary notes that reserve BTC would be held for at least 20 years, with sales allowed only to reduce the national debt.

Reporting on the latest draft says all BTC placed into the reserve would be banned from being sold, swapped, auctioned, encumbered, or otherwise disposed of for that 20 year period, with a cap afterward where the Treasury could recommend selling up to 10 percent of the reserve every two years. A TradingView recap of The Blocks coverage also highlights that the newest version drops an earlier explicit 1 million BTC purchase mandate and instead focuses on the lockup plus a study of budget neutral acquisition methods such as asset swaps and tariff revenues (summary here).

2. Why A 20 Year Lock Matters For Bitcoin

Analyses of ARMA note that the US already holds roughly 328,000 BTC from seizures, worth over 25 billion dollars, but without a clear policy on whether to hold or auction it (background). The bill would stop routine liquidation and push those coins into a do not touch bucket for decades.

Some coverage still references language authorizing acquisition of up to 1 million BTC over five years using budget neutral mechanisms, which would equal about 5 percent of Bitcoins eventual supply if fully executed (overview). Whether or not that exact target survives, the combination of no more federal auctions and potential structured buying is viewed by many analysts as structurally bullish for BTCs long term supply demand balance, although any accumulation would likely be slow.

3. Path To Law And Key Risks

ARMA has bipartisan sponsors in the House and support from some in the White House digital assets team, and a similar framework exists in earlier BITCOIN Act drafts and a Senate companion backed by pro crypto senators. That said, it is still just a bill: it has to clear committees, pass both chambers, be reconciled with any Senate version, and be signed, with midterm politics and fiscal concerns as potential hurdles.

Even if passed, the pace and size of actual Bitcoin purchases would depend on Treasury and Congress approving specific budget neutral strategies, which could be slower or smaller than headline numbers suggest. Volatility and criticism about using a volatile asset as a reserve could also constrain how aggressively any administration uses the authority.

Conclusion

If enacted as described, a US Strategic Bitcoin Reserve with a 20 year lock would convert government BTC from intermittent sell pressure into a long horizon holding and could eventually remove a meaningful chunk of supply from circulation. The real impact for crypto users will depend on whether ARMA becomes law and how aggressively Treasury is empowered to accumulate BTC, so the key things to watch are its progress through Congress and any later details on purchase mechanisms and caps.
