入门 SEC proposes first crypto custody rule for investment advisers and funds
Quick answer
The SEC proposed its first formal custody rule for digital assets on October 2, 2026, requiring registered investment advisers and mutual funds holding crypto to use only SEC-qualified custodians — entities that meet strict operational, financial, and cybersecurity standards. The proposal defines ‘crypto custody’ as the safekeeping of private keys and control rights over blockchain-based assets, and mandates segregation of client assets from custodian balance sheets. No effective date or compliance deadline is specified in the draft (Source: Bitcoin Magazine, 2026-10-02).
What does the proposal actually require?
It introduces three core obligations. First, any adviser or fund holding crypto on behalf of clients must engage a custodian approved under Rule 206(4)-2 — the same rule governing traditional securities custody, now extended to cover digital assets. Second, custodians must maintain proof-of-control infrastructure: they must demonstrate exclusive, auditable access to private keys without third-party dependency. Third, client crypto assets must be held separately from the custodian’s own balance sheet — no commingling with proprietary tokens or treasury holdings. The SEC did not define minimum capital requirements, insurance thresholds, or audit frequency in the proposal text; those remain open for public comment.
How does this affect different asset classes and market participants?
For spot Bitcoin and Ethereum ETFs — currently holding over $85 billion in AUM across U.S. exchanges (as of Q2 2026, per Bloomberg Intelligence) — the rule would reinforce existing custody arrangements, since most already use qualified custodians like Coinbase Custody or Fidelity Digital Assets. But for tokenized real-world assets (RWAs), stablecoins, and DeFi-native tokens, the impact is less clear: the proposal applies only to assets classified as ‘securities’ under U.S. law, and excludes commodities like BTC and ETH unless held within an investment vehicle subject to adviser regulation. Non-SEC-registered entities — including most decentralized protocols, DAO treasuries, and offshore exchanges — fall outside the scope entirely. That means the rule shapes institutional on-ramps, not peer-to-peer usage or self-custody.
What remains uncertain — and where are the risks?
Two major gaps stand out. First, the SEC did not clarify how it will assess ‘control’ over non-EVM or multi-sig wallet structures — a critical ambiguity for institutions holding Solana, Cardano, or Cosmos-based tokens. Second, no definition is provided for ‘qualified custodian’ beyond referencing existing Rule 206(4)-2 criteria, which were built for equities and bonds, not permissionless ledgers. That creates interpretive risk: a custodian compliant with legacy standards may still fail a crypto-specific audit. Also unaddressed is cross-border custody — e.g., whether a Singapore-based entity licensed by MAS could qualify if it meets SEC technical benchmarks. These omissions mean final implementation depends heavily on comment submissions due by January 2027 (Source: Bitcoin Magazine, 2026-10-02).
Frequently asked questions
Q: Does this rule ban self-custody or personal wallet use? A: No. The proposal applies exclusively to registered investment advisers, mutual funds, and ETFs acting on behalf of clients. It does not regulate individuals holding crypto in MetaMask, Ledger, or other non-institutional tools.
Q: Will this force exchanges like Binance or OKX to register as custodians? A: Not directly. The rule targets entities providing custody to regulated funds, not retail trading platforms. However, if such platforms seek to offer custodial services to U.S. ETFs or RIAs, they would need to apply for qualification — a process that remains undefined in the current draft.
