SEC Crypto Custody Rule: What’s Changing for Banks

SEC just took its biggest step toward fixing crypto custody rules since the Biden-era attempt collapsed under industry pressure. This week, the agencysubmitted a revised proposalto the White House’s Office of Management and Budget for review — a preliminary but critical stage in the rulemaking process. If you hold crypto in any regulated account or plan to, this rule will directly affect how your assets are stored and who’s allowed to hold them.

What the Custody Rule Actually Covers

Let’s start with why this matters for you. Under existing SEC regulations, investment advisers — the firms that manage your money — must place client assets with a “qualified custodian.” That’s a chartered bank, a trust company, a registered broker-dealer, or a futures commission merchant. The problem: until now, there’s been no clear guidance on whether crypto fits into that framework.

Can your financial adviser hold Bitcoin in your portfolio? Technically, yes — but the rules aboutwho stores ithave been vague. That ambiguity has kept many wealth managers, pension funds, and registered investment advisers on the sidelines. They want to offer crypto exposure, but compliance departments won’t approve custody arrangements that lack explicit SEC blessing.

The new rule aims to “clarify the framework for the custody of crypto assets for investment advisers and investment companies” while removing what the SEC callsburdens from outdated provisions. In plain terms: make it clear which institutions qualify to hold crypto on behalf of clients, and update rules that were written before digital assets existed.

What Went Wrong the First Time

Gary Gensler’s SEC tried this in 2023 — and failed. The original proposal would have required investment advisers to place client crypto exclusively with qualified custodians, but defined those custodians so narrowly that most crypto-native firms were excluded.

Gensler publicly warned that crypto platforms “generally operate” in ways that made them unsuitable as custodians. The result was a rule that effectively would have forced all crypto custody through traditional banks — institutions that, at the time, had little infrastructure or interest in holding digital assets.

The opposition was bipartisan and unusually broad. JPMorgan, venture firm a16z, multiple crypto platforms, and even the Small Business Administration submitted comment letters arguing the proposal was unworkable. The rule was quietly shelved before it could reach a final vote.

How the New Approach Differs

SEC Chair Paul Atkins has taken a fundamentally different posture. Since taking office, his crypto regulatory agenda has included approvingNasdaq Bitcoin index options, issuing guidance that memecoins aren’t securities, and building a framework (called “Regulation Crypto Assets“) for tokenized asset offerings.

The new custody proposal — while details remain limited because it’s in preliminary review — appears designed to expand, not narrow, who qualifies. The proliferation of new federal trust bank charters specifically created for digital asset custody changes the landscape. Firms like Anchorage Digital, Paxos, and BitGo now hold federal or state trust charters that didn’t exist when Gensler drafted his version.

The tone shift is significant. Gensler’s proposal started from the position that crypto is risky and custodians need strict gatekeeping. Atkins’sapproach starts from the positionthat crypto is here to stay and regulations should enable institutional participation rather than block it.

What This Means for Banks and Crypto Firms

If the rule goes through as expected, several things change:

For traditional banks:A clear custody framework removes the biggest regulatory barrier to offering crypto services alongside stocks, bonds, and other traditional assets. Morgan Stanley’s E*TRADE, which recently rolled out spot crypto trading for eligible clients, has been operating in a gray zone. Formal rules would put thatinstitutional crypto adoptionon firm legal footing.

For crypto-native custodians:Firms with federal or state trust charters could be officially recognized as qualified custodians, allowing investment advisers to use them without legal uncertainty. This is the outcome Anchorage, BitGo, and Coinbase Custody have lobbied for.

For spot Bitcoin and Ethereum ETFs:The custody question has always lurked beneath ETF approvals. When BlackRock holds Bitcoin for its iShares ETF, the custody arrangement with Coinbase is technically operating ahead of formal rules. A custody rule would retroactively validate these structures and likely open the door for more diverse custodian competition.

For retail investors:If your financial adviser manages your IRA, brokerage account, or retirement portfolio, they’ll have a clearer pathway to including crypto allocations. That doesn’t mean theywill— but the regulatory excuse for not offering it disappears.

The Timeline: Don’t Hold Your Breath

An October 2026 formal proposal date has been floated, but the SEC’s rulemaking timeline estimates have a long history of optimism. Even after a proposal is published, there’s typically a 60–90-day comment period, followed by months of deliberation before a final rule.

Realistically, a finalized custody rule is a 2027 event. But the direction of travel is now clear, andinstitutional crypto infrastructureis being built ahead of the formal rules — just as exchanges listed spot Bitcoin ETFs before the SEC formally created a custody framework to govern them.

This rule isn’t exciting in the way a Bitcoin rally or a new L1 launch is exciting. It’s plumbing — the regulatory infrastructure that determines whether crypto remains a niche asset class or integrates into mainstream portfolio construction.

The fact that the Atkins SEC is reviving this effort, rather than letting Gensler’s failed attempt die quietly, tells you something about the current administration’s commitment to crypto-friendly regulation. It also tells you that the industry’s lobbying effort worked. The original rule was killed by a coalition of banks and crypto firms that rarely agree on anything — and the replacement appears designed to satisfy both sides.

The biggest beneficiaries will be the custodians that already hold federal trust charters. They’ve spent years and millions of dollars obtaining those licenses specifically for this moment. When — not if — the rule lands, they’ll be first in line.

What is a qualified custodian for crypto? 

A qualified custodian is a financial institution approved by the SEC to hold client assets on behalf of investment advisers. Currently, that includes chartered banks, trust companies, registered broker-dealers, and futures commission merchants. The new rule wouldclarify which of these can hold digital assetsand whether crypto-native firms with trust charters qualify.

What was SAB 121 and why did it matter? 

SAB 121 (Staff Accounting Bulletin 121) was a 2022 SEC directive that forced banks to record crypto held in custody as liabilities on their balance sheets — making it financially prohibitive for banks to offer crypto custody. The SEC rescinded SAB 121 under Chair Atkins, removing a major accounting barrier before pursuing this broader custody rule.

How does this affect Bitcoin ETFs? 

Spot Bitcoin ETFs like BlackRock’s IBIT rely on custody arrangements with crypto firms (primarily Coinbase). A formal custody rule would provide legal certainty for those arrangements, potentially enablemore diverse custodian options, and reduce regulatory risk for issuers and investors alike.

Can my financial adviser add crypto to my portfolio now? 

Technically, some advisers already offer crypto exposure through ETFs or direct custody, but many compliance departments have waited for explicit SEC guidance before approving digital asset allocations. The new custody rule would remove that regulatory uncertainty, though individual firms will still set their own risk policies.

When will the SEC crypto custody rule be finalized? 

The rule is currently in preliminary White House review. A formal proposal could come as early as October 2026, followed by a public comment period and final deliberation. A finalized rule is most likely a mid-2027 outcome, based on typical SEC rulemaking timelines.
