Big firms want to trade crypto with the structure of traditional finance, including orders intermediated by brokers and asset custody separate from the exchange

Context & Ripple Effects
This piece lands at the hinge of crypto's institutional rebuild: after FTX's collapse discredited the exchange-as-everything model, incumbents have been re-entering through structures that look like traditional finance — Standard Chartered and other banking groups spinning up separate crypto subsidiaries explicitly betting fund managers will pick trusted brands over opaque crypto-native firms.
The constraint Matt Levine is describing is structural, not attitudinal: big firms need someone else to hold the assets and route the orders before they will trade at scale. Custody is the chokepoint — [[a:875286|BNY Mellon and other custodial banks want the business but are blocked by the SEC's SAB 121 accounting rule]], while crypto executives had earlier lobbied for lighter-touch CFTC oversight rather than SEC treatment. The push for brokered, custody-separated trading is what reconciles those two threads.
First-order effects
- Native crypto exchanges lose their captive asset base: if institutions require custody separated from the venue, exchanges stop being both warehouse and marketplace and must compete on execution quality alone.
- Custodial banks and qualified custodians become mandatory intermediaries in every institutional crypto trade, converting a side business they have been barred or hesitant to enter into a toll position.
Second-order effects
- The SAB 121 accounting rule shifts from a nuisance to the binding constraint on the whole model — resolving it (via charter applications like the ones Circle and BitGo are reportedly preparing) determines whether bank-grade custody scales.
- Broker-dealers gain a new product line intermediating crypto orders for institutional clients, pulling trading flow that previously went direct to exchanges and forcing venues to court brokers the way equity exchanges do.
Third-order effects
- If custody-separated, brokered trading becomes the institutional standard, crypto splits into a two-tier structure — regulated banks holding assets, regulated venues executing — mirroring equities market structure and ending the vertically-integrated exchange era that FTX exemplified.
- Regulatory jurisdiction fights between the SEC and CFTC get settled de facto by market structure: whichever agency's rules accommodate bank custody and brokered flow effectively governs institutional crypto.
The trend: Crypto market structure is converging on the traditional-finance template of segregated custody, broker intermediation, and chartered institutions, with each incumbent entrant making the convergence harder to reverse.
