The SEC's boring custody rule will outlast its crypto exemptions

The durable piece of the SEC's crypto rulemaking is the boring one, and it moved this week when Taylor Lindman, chief counsel of the agency's Crypto Task Force, told a CoinDesk Policy & Regulation event in Washington that the proposal covering both investment firms and broker-dealers now sits under review at the Office of Management and Budget. Once the White House clears it, the commission can formally propose the rule and take comment from the industry and the public.

Two businesses live inside one draft. Broker-dealers are being told to expect an answer on whether they can carry a non-security crypto asset without needing "some special registration," while advisers are being told to expect clarity on where client assets can be parked — the example Lindman gave was a state-chartered trust. For advisory firms, the second question is the one with a file behind it: since September 2025 the SEC has allowed advisers to park customer assets with state-chartered trusts as qualified crypto custodians, a position rather than a rule, and that is the arrangement advisers have had to work from while the drafting continued.

Lindman treated that move and a December staff statement as the interim scaffolding: the statement was meant to steer broker-dealers on handling crypto custody until rules are in place, and the September 2025 guidance gave advisers a named place to park assets. A proposal built on both would cement the patches in place rather than design a custody perimeter from scratch.

Lindman cast the aim as assimilating existing securities intermediaries and existing market participants "into a world where they feel comfortable utilizing blockchain, even holding crypto assets, transacting crypto assets," a category he said spans assets that are securities and assets that are not. Writing one instrument for two sets of intermediaries suggests the commission wants a single custody answer it can point to for both.

He also called the work "foundation laying," adding that "some of the foundation laying is boring," and the framing elsewhere in his remarks was explicitly long-horizon: the exercise is to take what was once "this really unique and scary asset" and put stablecoins and non-security crypto assets "within a framework that can be built upon for every generation to come." Rules pitched at that horizon are the ones compliance departments staff against, and "we need to kind of meet the market where it's at" is the tell that this rule will describe existing practice more than it changes it.

The SEC's tokenized-securities exemption, delayed in August after pushback from the White House and SIFMA, is the cautionary case for permissions that arrive outside the rulemaking process; a CFTC crypto rule sits under review at the Office of Management and Budget with its contents undisclosed. Permissions granted by exemption carry review clocks and expiry dates, while a rule that survives notice and comment does not — the least glamorous item on this agenda is the one most worth tracking.

The 2023 attempt is why the distinction matters. Under then-Chair Gary Gensler, the SEC pursued a custody rule that said crypto firms themselves would not qualify to custody the assets, and that rule never reached final form before President Donald Trump returned to the White House and appointed crypto-friendly leadership at the agency. What has changed is the population being written in: this version aims at the incumbent intermediaries rather than at crypto-native firms seeking admission.

Congress is not supplying the answer. The Senate's Clarity Act failed 49-50 this month, and that defeat moved market-structure definitions to the agencies and the committees, where rules are quicker to write and quicker to reverse than a statute. CoinDesk, which hosted the event and reported the remarks, describes an agency blazing through much of its crypto agenda while trying to nail down a structure in the absence of a solution from Congress. Custody is the piece of that agenda arriving as a rule rather than a dispensation, and its comment period is where advisers and brokers will get to say what they can actually operate.

The account of Lindman's remarks ends as stablecoins come up, and the coverage does not say where he went next, nor when the OMB review finishes or when a proposal would publish. Watch whether the state-chartered trust survives comment as the named destination for advisory client assets. If it does, the trust charters assembled across the crypto custody market become the default answer for advisory accounts, and the firms that treated the September 2025 guidance as a draft will find the final rule describing the business they already run.
