Why Custody Insurance Matters in September 2025
Institutions now hold billions in digital assets, and regulators expect professional risk transfer—not promises. Custody insurance providers bridge the gap by transferring losses from theft, key compromise, insider fraud, and other operational failures to regulated carriers and markets. In one line: custody insurance is a specialized policy that helps institutions recover financial losses tied to digital assets held in custody (cold, warm, or hot) when defined events occur. As spot ETF flows and bank re-entries accelerate, boards want auditable coverage, clear exclusions, and credible capacity. This guide highlights who actually writes, brokers, and structures meaningful digital-asset custody insurance in 2025, and how to pick among them. Secondary considerations include capacity, claims handling, supported custody models, and regional eligibility across Global, US, EU, and APAC.
How We Picked (Methodology & Scoring)
- Scale/Liquidity (30%) — demonstrated capacity, panel depth (carriers/reinsurers/markets), and limits available for custody crime/specie.
- Security & Underwriting Rigor (25%) — due diligence on key management, operational controls, audits, and loss prevention expectations.
- Coverage Breadth (15%) — hot/warm/cold support, staking/slashing riders, social-engineering, wallet recovery, smart-contract add-ons.
- Costs (15%) — indicative premiums/deductibles vs. limits; structure efficiency (excess, towers, programs).
- UX (10%) — clarity of wordings, onboarding guidance, claims transparency.
- Support (5%) — global service footprint, specialist teams (DART/crypto units), and education resources.
We prioritized official product/security pages, disclosures, and market directories; third-party datasets were used only for cross-checks. Last updated September 2025.

- Align limits/deductibles with AUM, TVL, and worst-case loss scenarios.
- Ask for claims playbooks and incident response timelines.
- Review audits & controls (SOC 2, key ceremonies, disaster recovery).
- Query reinsurance backing and panel stability.
- Red flags: vague wordings; “cyber-only” policies for custody crime; no clarity on key compromise.

FAQs
What does crypto custody insurance cover?
Typically theft, key compromise, insider fraud, and sometimes extortion or vendor breaches under defined conditions. Coverage varies widely by wording; verify hot/warm/cold definitions and exclusions. Munich Re
Do I need both crime and specie?
Crime commonly addresses employee dishonesty and external theft; specie focuses on physical loss/damage to assets in secure storage. Many carriers blend elements for digital assets—ask how your program handles each. Canopius
Can staking be insured?
Yes—some reinsurers/insurers offer staking/slashing riders or separate policies; smart-contract risk often requires additional cover like Chainproof. Munich Re+1
How much capacity is available?
Depends on controls and market appetite. Lloyd’s syndicates and reinsurers like Munich Re can support sizable towers when risk controls are strong. Lloyds+1
How do I reduce premiums?
Improve key-management controls, segregate duties, minimize hot exposure, complete independent audits, and adopt continuous monitoring/fraud screening (e.g., Coincover-style prevention). coincover.com
Are exchanges’ “insured” claims enough?
Not always—check if coverage is platform-wide, per-customer, warranty-backed, or contingent. Ask for wordings, limits, and who the named insureds are. The Digital Asset Infrastructure Company
