SEC Crypto Custody Rules Head to White House, Proposal Due by October 2026

2 hours ago 15

The Securities and Exchange Commission has quietly reopened one of crypto’s oldest headaches: who exactly gets to hold digital assets on behalf of clients, and under what rules. On August 25, the agency sent its long-awaited proposal to rewrite the SEC crypto custody rules to the Office of Information and Regulatory Affairs, the White House office that vets economically significant regulations before they ever reach the public. It’s a technical, bureaucratic step. But for an industry that has spent years lobbying for clearer custody standards, it’s also the closest thing to real movement they’ve seen.

Key takeaways

The SEC submitted proposed amendments to its Custody Rule to OIRA on August 25, following a White House meeting between President Donald J. Trump and crypto industry executives.
OIRA is treating the proposal as an economically significant regulation, which means SEC Commissioners cannot vote on it or discuss its contents until that review wraps up.
The SEC expects to publish the proposed rulemaking by October 2026, opening at least a 60-day public comment window.
Even after publication, a second commission vote and further analysis are required, meaning full implementation could take several years.
Institutional Bitcoin ETF holdings rose 7.5% to 535,723 BTC in the second quarter of 2026, even as Bitcoin’s price fell 14.2%, pushing institutional ownership of ETF shares to 44.2% from 38.4%.

SEC Proposes Amendments to Crypto Custody Rule

The SEC’s proposal aims to clarify exactly how investment advisers and investment companies are allowed to hold crypto assets for clients, replacing years of ambiguity with something closer to a defined framework. According to The Block, the agency said the rulemaking would “clarify the framework for the custody of crypto assets for investment adviser and investment companies, as well as make other modernizations needed to remove burdens from certain outdated provisions that are no longer needed to provide investor protection given the evolution in the markets and security trading and holding practices.” In plain terms: the current rulebook was written before crypto existed, and advisers have been asking the SEC for years how they’re supposed to comply with it.

Submission and Regulatory Review Process

The formal submission landed at OIRA, a division of the Office of Management and Budget tasked with screening federal regulations before they go public. Because the proposal has been classified as economically significant, it now sits in a review queue that carries strict confidentiality rules. SEC Commissioners are barred from voting on the rulemaking, or even discussing its details publicly, until OIRA finishes its assessment. That silence is standard procedure for major rules, but it also means the exact contents of the proposal remain unknown outside the agency for now.

Role of the White House and OIRA

The timing is not incidental. The submission followed a White House meeting between President Donald J. Trump and crypto industry executives, placing the custody overhaul squarely within a broader push from Washington to modernize digital asset oversight. The SEC’s move comes under Chair Paul Atkins, who has overseen a series of crypto-friendly regulatory shifts over the past year, including guidance clarifying that memecoins are not securities and clarification on which staking activities fall outside securities law. Just last week, the agency also introduced “Regulation Crypto Assets,” described as a tailored offering regime meant to help firms raise capital while still protecting investors. Atkins has additionally signaled plans for an innovation exemption designed to fast-track certain crypto products, though that framework has not yet materialized.

Expected Impact and Timeline of Amendments

Don’t expect clarity overnight. The SEC has indicated it anticipates publishing the proposed rulemaking no later than October 2026, which would trigger a minimum 60-day window for public comment. That’s the earliest point at which the industry will actually see the fine print of what regulators have in mind for crypto custody compliance.

Regulatory Certainty and Implementation Challenges

Even once published, the proposal won’t hand custodians a rulebook they can immediately follow. It offers guidance on what regulators expect from a custodian, but it stops short of providing absolute certainty right away. Before anything becomes binding, the SEC still needs to complete further analysis and hold a second commission vote. Given that sequence, industry participants are likely looking at a wait of several years before compliance actually becomes mandatory. This matters because it tempers any assumption that a fix is imminent — the review process itself is the story right now, not a finished rule.

Institutional Demand Trends in Bitcoin ETFs

While regulators work through the paperwork, institutional investors aren’t waiting around. Bitcoin ETF flows during the second quarter of 2026 show a clear divergence: big money is buying into crypto exposure even as the broader market cools.

Growth of Institutional Holdings Despite Market Downturn

Institutional Bitcoin ETF holdings climbed 7.5% to 535,723 BTC in Q2 2026, despite Bitcoin’s price sliding 14.2% over the same period. That pushed institutional ownership of ETF shares to a high of 44.2%, up from 38.4% previously. Meanwhile, total ETF holdings across all investor types actually fell 6.6% to 1.21 million BTC — meaning institutions were adding exposure at the exact moment other holders were pulling back. That contrast is worth sitting with: it suggests institutional cryptocurrency demand is strengthening independently of short-term price swings, a pattern that tends to reflect longer investment horizons rather than momentum chasing.

Compliance Costs and Challenges for Crypto Custody

Regulatory clarity is only half the equation — cost is the other. Even with clearer rules on the horizon, crypto custody compliance carries real financial weight. Custody fees currently run between four and 15 basis points annually, and insurance coverage for custodians ranges from $200 million to $750 million to provide adequate protection.

Those numbers create a meaningful barrier for smaller advisers, who are likely to face proportionally higher compliance costs than larger firms with more resources to absorb them. That’s the tension sitting underneath this whole rulemaking effort: a clearer custody framework could open the door for more institutions to enter crypto markets, but the cost of actually meeting those standards may keep the door narrower for smaller players. Whether reforms extend adoption meaningfully beyond regulated funds — or simply reinforce the advantage of the largest custodians — will likely show up in filings well before the rule itself takes effect.
