What Assets Can Have Spot ETFs? (Crypto, Gold, etc.)

Spot ETFs provide regulated, brokerage-native exposure to assets by holding the underlying directly (or via tightly integrated mechanisms). This explainer surveys which assets can support Spot ETFs, why some are more suitable than others, and how custody, liquidity, and regulation intersect to make Spot ETFs feasible across commodities and crypto.

Gold: The Archetypal Spot ETF Gold Spot ETFs (e.g., GLD) paved the way by holding vaulted bullion under rigorous custody (segregation, audits, insurance). Liquidity is deep, spreads are tight, and disclosure practices are mature. This template informs crypto Spot ETFs—substituting digital assets for bullion in custody architecture.

Crypto: Bitcoin and Ethereum

Bitcoin: Spot ETFs hold BTC in cold storage; creation/redemption anchors price to spot; see How Does a Spot ETF Work?.
Ethereum: Similar custody with ETH; staking policies and treatment vary by jurisdiction and issuer; read What Is a Spot Ethereum ETF?. Custody readiness, market surveillance cooperation, and clear disclosures drive feasibility.

Other Commodities Spot ETFs exist for other physically backed commodities (silver, platinum) when custody and logistics are standardized. Networked settlement (for metals: vault transfers; for energy: storage and deliverables) must align with fund operations.

Custody and Logistics Requirements Assets suitable for Spot ETFs share traits:

Custody Reliability: Secure storage and transfer mechanisms.
Auditability: Independent verification of holdings and controls.
Insurance Clarity: Defined coverage for custody-related risks.
Operational SLAs: Documented timing and reconciliation. Crypto aligns via cold storage and multi-sig controls; metals align via vault auditing.

Liquidity and Market Structure Feasibility also depends on liquidity:

Depth-of-Book: Sufficient size near the mid.
Turnover: Consistent volume to support tight spreads.
Venue Quality: Reputable exchanges or OTC desks for acquisition. ETF participation can further densify liquidity; see Spot ETF Impact on Market Liquidity.

Regulatory Pathways Approvals hinge on local regulations and supervisory comfort:

Disclosure Standards: Methodology, holdings, and incident communications.
Market Integrity: Surveillance agreements and manipulation detection.
Custody Oversight: Qualified custodians and audit cadence. Jurisdictions that recognize mature practices are more open to Spot ETFs across assets.

Operational Differences: Crypto vs Metals

Crypto: On-chain confirmations, key management, multisig, cold storage governance.
Metals: Physical handling, vault audits, assay and chain-of-custody documentation. Both require rigorous controls; crypto adds cryptographic and network layers.

Investor Use Cases

Retail and Advisors: Brokerage-native access with transparent reporting.
Institutions: Audited sleeves and simplified accounting compared to direct holdings. Use cases multiply as custody and disclosure norms standardize.

Limitations and Edge Cases

Perishables/Complex Deliverables: Assets with complicated storage or quality variance are poor candidates.
Thin Liquidity: Assets without sufficient turnover may yield wide spreads and unstable tracking.
Policy Ambiguity: Lack of regulatory clarity impedes approval.
