Fed's limited master account proposal opens 60-day comment period, giving crypto firms direct access to central bank payment rails without a full bank charter. Kraken already secured access. The final rule could arrive in months.
The U.S. Federal Reserve opened a 60-day comment period on a revised version of its limited master account proposal, a long-sought mechanism for crypto firms to clear and settle payments through the central bank's payment rails without holding a full banking charter. The Fed's Wednesday statement described accounts that offer payment services with automated overdraft controls, no intraday credit, and no interest on balances. Firms with "diverse business models" – a phrase that covers stablecoin issuers, digital asset exchanges, and other non-bank payment processors – can apply.
The new proposal is "substantially similar to the prototype outlined" in the December request for information, the Fed said. The earlier version drew a 45-day comment period. This iteration incorporates feedback: closing balance limits are now tied to an institution's expected payment activity, and the maximum closing balance was increased. The change matters for crypto firms processing high-volume payments: larger daily balances reduce the need for frequent end-of-day sweeps to external custody accounts, cutting operational risk and counterparty exposure.
The Fed included a detailed description of what a limited master account does not provide:
This design deliberately limits the account to settlement finality – once a payment clears through the Fed, it cannot be reversed. For crypto firms, that finality is the primary value. The absence of credit and yield confines these accounts to payment efficiency rather than balance-sheet expansion.
In March, Kraken became the first crypto bank to receive a limited master account, granted by the Federal Reserve Bank of Kansas City. That access was not under a federal rule from the Fed board in Washington. The Fed has now asked regional banks to pause consideration of certain applications while it finishes the national rule. The Kraken deal set a precedent but also created a patchwork of regional standards. The new rule aims to unify eligibility requirements and remove district-to-district inconsistency.
The Fed's request for a pause signals that the board wants to centralize control over the approval process, avoiding the fragmentation that could occur if each of the 12 regional Fed banks sets its own terms.
Limited master accounts – often called "skinny" accounts in crypto circles – provide direct access to Fedwire and the Fed's automated clearinghouse. The mechanism includes three key features:
For a stablecoin issuer processing $1 billion in daily redemption volume, a higher closing balance limit means fewer end-of-day sweeps to external bank accounts. Each sweep introduces settlement timing risk and counterparty cost. The skinny account removes those layers, making crypto payment rails more competitive with traditional wire transfers.
The design explicitly targets settlement efficiency. The direct beneficiaries are firms that move large payment volumes between counterparties:
Firms that depend on leverage or credit – such as trading desks or lending platforms – see little direct benefit. The account offers no intraday credit and no yield. The value proposition is purely operational.
One day before the Fed's proposal, President Donald Trump issued an executive order directing the Fed to review how it grants uninsured depository institutions and non-bank financial firms access to payment accounts. The order also asked whether the 12 regional Fed banks should act independently on such accounts. The coincidence of the two processes creates a rare window of regulatory alignment: the Fed's 60-day comment period and the executive order's 90-day review deadline overlap, meaning a final rule could arrive within months rather than years.
The latest version of the Parity Act – which updates language around payment stablecoins – also directs the IRS to report on how a de minimis exemption for crypto transactions might work. Combined with the Fed's proposal, the regulatory framework for stablecoins is taking clearer shape. The CLARITY Act Consolidation Sets Up Summer Senate Vote on Crypto further reduces legal uncertainty for firms building on crypto payment rails.
The Fed's proposal and the executive order together put pressure on a single question: how wide should the door be? The comment period will draw objections from traditional banks, which may argue that limited master accounts create an uneven playing field. If those objections gain traction, the Fed may tighten eligibility or insert counterparty exposure limits.
Risk to watch: any surge in stablecoin redemptions or a major operational failure at a crypto bank could prompt the Fed to narrow eligibility criteria. The stability of reserves backing crypto payment activity is the key variable the Fed will monitor.
For traders and investors, the structural shift is clear: crypto firms are gaining a direct line to the Fed's payment system. The unit economics improve for settlement-focused operations. The firms that benefit most are those that move large fiat volumes, not those that borrow or lend. The comment period runs 60 days. After that, the Fed will produce a final rule. The Fed Skinny Accounts: Crypto's Limited Fedwire Entry analysis provides a deeper look at the prototype that led to this proposal. The next concrete marker is the number of crypto firms that publicly announce applications once the final rule takes effect.
