Actuarial & Risk Modeling Challenges

1. Fundamental Actuarial Challenges

Digital asset insurance presents a set of actuarial challenges that differ qualitatively from those in traditional property/casualty, life, or even conventional cyber insurance. This section identifies the structural barriers to actuarial pricing and reserving. Across the 18 jurisdictions surveyed in this domain, only a minority impose any insurance obligation at all, and none prescribes an actuarial methodology — so the modeling burden falls almost entirely on individual underwriters operating with thin data.

1.1 Limited Loss History

Meaningful digital asset loss data exists only from approximately 2014 (Mt. Gox). This provides roughly a decade of observations — compared to centuries of data for property insurance or multiple decades for cyber. The dataset is further constrained by:

• Survivorship bias: Exchanges that suffered catastrophic losses (Mt. Gox, DMM Bitcoin) ceased operations. Their risk profiles and exposures are removed from ongoing datasets. DMM Bitcoin (~$305-308 million, ~4,502.9 BTC, May 2024, Lazarus suspected) shut down in December 2024, transferring assets to SBI VC Trade.
• Non-reporting: Many smaller theft events and DeFi exploits go unreported or are resolved privately, so aggregate aggregator counts likely understate actual frequency.
• Heterogeneity: The "digital asset custody" risk class encompasses fundamentally different risk profiles — from centralised exchange hot wallets to DeFi protocol smart contracts to cross-chain bridge validators — making it difficult to construct credible actuarial tables.

The limited dataset means traditional credibility-weighted pricing approaches require heavy reliance on subjective judgment, analogous to the early years of cyber insurance in the 2000s. Aggregate annual theft is concentrated and lumpy: industry trackers report roughly US$3.41 billion stolen in 2025 (Chainalysis), of which the single Bybit hack (~US$1.5 billion, 21 February 2025) represented close to 44% — the largest single theft on record, recovered without any traditional insurance. Preliminary first-quarter 2026 theft was reported at roughly US$168.6 million, down ~88% year-on-year (self-reported aggregator data, preliminary). The year-to-year swing of an order of magnitude, driven by a handful of mega-events, is itself a defining actuarial feature.

1.2 Non-Stationary Risk Landscape

Unlike natural catastrophe risk, where the underlying physical processes change slowly, the digital asset threat landscape evolves rapidly:

• Attack vectors shift year-to-year: The dominant loss channel rotates between DeFi smart-contract exploits, centralised-service compromises, bridge hacks, and private-key theft from one period to the next.
• New asset classes and protocols emerge continuously: Each new DeFi primitive (yield farming, liquid staking, restaking, cross-chain bridges) introduces novel risk categories not present in historical data.
• Security technology co-evolves with threats: Multi-party computation (MPC), hardware security modules (HSMs), and threshold signature schemes continuously change the risk landscape, rendering historical loss data partially obsolete for forward-looking pricing.

This non-stationarity means standard actuarial methods assuming a stable loss-generating process (e.g., Poisson frequency models with stable parameters) are unreliable without continuous recalibration.

1.3 Correlated and Aggregation Risk

Digital asset losses exhibit high correlation, creating aggregation risk that is particularly dangerous for insurers:

• Single protocol failure: A vulnerability in a widely used protocol (e.g., a shared multisig or wallet provider, as in the Bybit hack) can trigger losses across multiple insured entities simultaneously.
• Bridge dependency: Cross-chain bridges represent single points of failure affecting multiple blockchains; a bridge validator compromise can affect an entire ecosystem at once.
• State-sponsored campaign risk: A concentrated campaign by a single threat actor (e.g., North Korea-linked groups, attributed ~US$2.02 billion of 2025 losses) against insured entities could exhaust an insurer's aggregate capacity within weeks.
• Market-wide contagion: FTX's collapse triggered cascading failures across the ecosystem (BlockFi, Genesis, Voyager) — and reached the insurance layer, with Relm (Bermuda) holding more than US$15 million of policy exposure to FTX-related entities — illustrating how a single counterparty failure can propagate.

For an insurer writing multiple digital asset policies, the probability that several policies trigger simultaneously is materially higher than in most traditional insurance lines. This has direct implications for portfolio aggregation limits and reinsurance purchasing — a concern sharpened by extreme market concentration in the specialty: Bermuda, for instance, hosts only two specialty digital-asset insurers plus one captive.

1.4 Asset Price Volatility

The insured asset itself is volatile, creating unique challenges:

• Coverage adequacy drift: A policy written when 1,000 BTC was worth $30 million may be grossly inadequate months later when the same holding is worth $100 million, or may provide substantial over-insurance during price declines.
• Claims valuation ambiguity: Should a stolen asset be valued at time-of-theft, time-of-discovery (which may be days or weeks later), or time-of-claim filing? Bitcoin's annualised volatility of 50-80% makes this distinction materially significant.
• Stablecoin depeg risk: Even "stable" assets can lose value — UST/Luna's collapse in May 2022 destroyed ~$40 billion in value. USDC briefly depegged to $0.87 in March 2023 during the Silicon Valley Bank crisis.

1.5 Key-Person Dependency Risk

Many digital asset businesses have critical dependency on a small number of key personnel who control private keys, protocol governance, or operational security. The loss of a key person (through death, incapacitation, defection, or arrest) can render assets inaccessible. This creates an intersection with key-person life insurance that has no direct analogue in traditional commercial crime underwriting — and is reflected in regulation: Bahrain explicitly mandates keyman-risk insurance (alongside professional indemnity and cybersecurity cover) for all crypto-asset licensees.

1.6 Moral Hazard in Self-Custody Claims

Claims involving self-custody (where the insured is also the custodian) present acute moral hazard:

• Simulated theft: An insured entity could claim a hack occurred while retaining access to the assets. Blockchain transparency partially mitigates this (fund movements are visible), but privacy tools (mixers, cross-chain swaps) can obscure the trail.
• Inadequate security incentives: If insurance fully covers losses, insured entities may underinvest in security — particularly in costly measures like multi-party computation or geographic key distribution.
• Information asymmetry: The insured possesses far more information about their security posture, key management practices, and operational vulnerabilities than the underwriter. Smart contract audit results, penetration testing reports, and incident response capabilities are difficult to verify externally.

This is one reason custody-framework regulators ration self-custody rather than insure it: Canada's CIRO Digital Asset Custody Framework (February 2026) permits self-custody up to only 20% of holdings, and then only at the highest internal-control tier.

2. Current Modeling Approaches

2.1 Scenario-Based Modeling

Given the limitations of historical data,

UK Lloyd's syndicates and specialist underwriters predominantly rely on scenario-based approaches rather than traditional frequency-severity models:

Lloyd's Realistic Disaster Scenarios (RDS): Lloyd's requires syndicates to stress-test portfolios against defined scenarios. While Lloyd's has published detailed cyber RDS scenarios (cloud outage, widespread malware, cyber power outage), no publicly disclosed RDS scenario specifically targets digital asset or cryptocurrency risk as of the 2025 specification. However, the cyber RDS framework provides an analogue that can be adapted.

Source: Lloyd's, "RDS 2025 Realistic Disaster Scenarios Scenario Specification": https://assets.lloyds.com/media/e0c22427-dc75-419d-b9c1-5feb0823bc80/2.%20RDS%20Scenario%20Specification%20-%20January%202025.pdf

CyberCube scenarios for Lloyd's: CyberCube has developed three core cyber catastrophe scenarios for the Lloyd's market: a cyber power outage, a widespread malware event, and a cloud outage. These model how losses propagate through interconnected systems — a framework directly transferable to digital asset risk, where compromise of shared infrastructure (e.g., a widely-used multisig provider) could trigger correlated losses.

Source: CyberCube, "CyberCube launches three cyber scenarios for Lloyd's market": https://www.cybcube.com/news/three-cyber-scenarios-lloyds-market

Typical scenario categories for digital asset underwriting:

2.2 Blockchain Analytics for Risk Assessment

Underwriters increasingly use blockchain analytics platforms as inputs to the underwriting process:

• Chainalysis: Provides transaction monitoring, risk scoring, and investigation tools. Chainalysis data is a primary source for aggregate loss statistics (see Claims History & Loss Data).
• Elliptic: Offers wallet screening, transaction monitoring, and compliance solutions used by insurers to assess counterparty exposure.
• TRM Labs: Provides AI-native blockchain intelligence with dynamic risk scoring that adapts to emerging threat patterns.

These tools enable underwriters to evaluate:

• Whether an applicant's on-chain funds have exposure to sanctioned addresses
• Historical transaction patterns that may indicate elevated risk
• Real-time monitoring of insured wallet activity

However, blockchain analytics cannot assess off-chain risks (insider threats, physical security, key management practices), which remain subject to traditional underwriting questionnaires and security audits.

• Chainalysis, "2025 Crypto Crime Trends": https://www.chainalysis.com/blog/2025-crypto-crime-report-introduction/

2.3 Stress Testing Methodologies

Stress testing for digital asset insurers should incorporate:

1. Single-name concentration stress: What if the largest insured entity suffers a total loss?
2. Correlated event stress: What if a shared infrastructure provider (e.g., a major HSM vendor, a multisig platform, or a cloud custodian) is compromised, triggering claims across 20-50% of the insured portfolio?
3. Market stress overlay: What if a 70-80% asset price decline (as occurred in 2022) coincides with an increase in hack frequency (as operators cut security budgets)?
4. Regulatory event stress: What if a major jurisdiction bans crypto custody, triggering mass withdrawal events that overwhelm custodian infrastructure?

2.4 Catastrophe Modeling Analogues from Cyber Insurance

The most relevant modelling framework for digital asset insurance comes from cyber catastrophe modelling. Munich Re's whitepaper on systemic cyber insurance industry losses identifies key parallels:

• Event-based modelling simulates losses based on actual data composition and technical dependencies between insured entities
• Propagation modelling reflects how disruptions spread through shared platforms, software vendors, and digital supply chains
• Accumulation tracking monitors exposure concentration across shared risk factors

The digital asset sector adds a unique dimension: transparent on-chain data allows real-time observation of fund flows during and after an incident — a data source unavailable in traditional cyber insurance.

3. Solvency II / Capital Treatment

3.1 EIOPA's 100% Crypto Stress Remains a Pending Proposal — Not Yet Enacted

On 27 March 2025, the European Insurance and Occupational Pensions Authority (EIOPA) published final technical advice to the European Commission proposing a 100% capital requirement (one-to-one) for

EU insurers' crypto-asset holdings under the Solvency II standard formula. As of 4 June 2026 this remains advice, not binding law. The Solvency II Delegated Regulation (EU) 2026/269 — published in the Official Journal on 18 February 2026 and in force from 10 March 2026 (with most amendments applicable from 30 January 2027) — contains no crypto-specific capital charge. EIOPA's 100% stress would have to be introduced by a subsequent delegated act, which has not yet been adopted.

Key parameters of the proposal:

Rationale: EIOPA's empirical analysis found that current alternatives underestimate risk. The 80% stress applied to intangible assets is insufficient given the magnitude of historical crypto drawdowns. A 100% stress factor assumes total loss is possible and removes any diversification benefit.

Comparison to other Solvency II asset classes:

Future review: EIOPA acknowledged that "a possible broader adoption of crypto assets may require a more differentiated approach down the line," leaving room for future calibration based on expanded data.

Implication for digital asset insurance: If adopted, the 100% stress would make it prohibitively expensive for EU insurers to hold crypto assets on their own balance sheet, effectively requiring insured crypto exposure to be fully funded or reinsured. Until the subsequent delegated act is in force, EU insurers are not yet subject to a dedicated crypto charge under the standard formula.

3.2 Hong Kong IA — 100% Downward Stress for Insurers' Crypto Holdings

Outside the EU,

Hong Kong's Insurance Authority (IA) has advanced a closely parallel capital treatment under its Risk-Based Capital (RBC) framework. In consultation conclusions published 8 May 2026, the IA confirmed:

• A 100% downward stress factor on insurers' direct crypto-asset holdings, with no diversification benefit
• A look-through plus counterparty-default overlay for stablecoin exposures
• Exclusion of tokenised conventional instruments from the crypto stress treatment

Implementation is targeted for 31 December 2026, pending negative vetting by the Legislative Council. The IA's 100% downward stress mirrors EIOPA's calibration, signalling international convergence on a one-to-one capital charge for direct insurer crypto exposure — even as the EU's own charge remains a pending delegated act.

Hong Kong jurisdiction profile.

3.3 Standard Formula Limitations

The Solvency II standard formula was not designed for digital assets. Specific limitations include:

• No dedicated risk module: Crypto assets do not fit neatly into existing equity, property, or spread risk sub-modules — and Reg (EU) 2026/269 added no such module
• Correlation assumptions invalid: The standard formula assumes diversification benefits that do not hold for correlated crypto exposures
• Operational risk underweighted: The standard formula's operational risk charge (based on premium and reserve volumes) does not capture the unique operational risks of crypto custody

3.4 Internal Model Requirements

Insurers seeking a more risk-sensitive capital treatment may apply to use an internal model, but face significant hurdles:

• Data requirements: Internal models require statistically robust datasets that do not yet exist for most digital asset risk categories
• Model validation: National competent authorities must approve internal models, and regulators' own expertise in digital asset risk modelling remains limited
• Use test: The internal model must be genuinely used in risk management and business decisions, not merely constructed for capital relief

3.5 Basel Committee 1,250% Risk Weight (Banking Analogue)

While not directly applicable to insurers, the Basel Committee's treatment of crypto assets for banks provides a relevant benchmark:

Group 2b crypto assets (those not meeting hedging recognition criteria) are subject to a 1,250% risk weight. Combined with the 8% minimum capital requirement, this effectively requires banks to hold capital equal to the full value of their crypto exposure — identical in effect to EIOPA's proposed 100% stress and Hong Kong's 100% downward stress.

Implementation timeline: 1 January 2026 (extended from 2025 by BCBS).

Exposure limits: Banks' Group 2 crypto exposures must generally remain below 1% of Tier 1 capital. Breaching 2% triggers full Group 2b treatment for all crypto exposures.

3.6 IAIS Operational-Resilience Toolkit (February 2026)

The International Association of Insurance Supervisors (IAIS) published the final Application Paper on Operational Resilience Objectives and Toolkit on 12 February 2026 (following a July 2025 draft for consultation). The paper sets operational-resilience objectives and a supporting supervisory toolkit aligned to the Insurance Core Principles. It is technology-neutral and contains no crypto-specific provisions, but it is directly relevant to actuarial and operational-risk modelling for digital asset insurers in two ways:

• Insurers using DLT/blockchain for underwriting or claims processing must meet operational-resilience standards, including governance of third-party technology providers
• Third-party concentration and outsourcing risk — central to crypto-custody insurance (shared HSM vendors, multisig providers, cloud custodians) — is squarely within the toolkit's scope, reinforcing the correlated-aggregation modelling discussed in Section 1.3

The IAIS has still not issued any dedicated digital-asset-insurance guidance; it continues to apply existing, technology-neutral ICPs to crypto risk.

4. Valuation Challenges

4.1 Time-of-Loss vs. Time-of-Discovery vs. Time-of-Claim

The choice of valuation moment materially affects claim amounts:

Regulatory recommendation: Policies should specify valuation methodology at policy inception. Regulators should mandate time-of-loss valuation as the default, with a defined maximum detection window (e.g., 72 hours) beyond which time-of-discovery applies.

4.2 Cross-Chain Valuation

Multi-chain assets introduce additional complexity:

• The "same" token may trade at different prices on different chains due to bridge liquidity constraints
• Wrapped tokens (wBTC, wETH) may not trade at par with their underlying during stress events
• Layer-2 tokens and rollup-specific assets may lack reliable price oracles

4.3 Stablecoin Depeg Scenarios

Insurance policies covering stablecoins must address depeg risk:

• UST/Luna (May 2022): Algorithmic stablecoin collapsed from $1.00 to near zero, destroying ~$40 billion in value
• USDC (March 2023): Circle's USDC depegged to ~$0.87 following exposure to Silicon Valley Bank, before recovering within days
• Policy design question: Should a stablecoin at $0.87 be treated as a "loss" triggering claims, or must a more complete depeg occur?

Capital frameworks are beginning to address stablecoin valuation directly: Hong Kong's IA RBC overlay (Section 3.2) applies a look-through plus counterparty-default treatment to stablecoin exposures rather than a flat haircut, recognising that depeg risk is driven by reserve composition and counterparty default rather than market beta.

5. Emerging Solutions

5.1 Real-Time On-Chain Risk Monitoring

The transparency of public blockchains enables risk monitoring approaches unavailable in traditional insurance:

• Real-time wallet monitoring: Underwriters can observe insured wallet balances and transaction patterns continuously
• Anomaly detection: AI/ML models can flag unusual transaction patterns indicative of compromise
• Automated policy triggers: Smart contract-based policies could adjust premiums or trigger claims automatically based on on-chain events

Limitation: On-chain monitoring cannot detect off-chain risks (social engineering, insider threats, physical security breaches) until funds actually move.

5.2 Smart Contract Auditing as Underwriting Input

Smart contract security audits are emerging as a standard underwriting input for DeFi coverage:

• Audit firms: Trail of Bits, OpenZeppelin, Consensys Diligence, Sherlock, Code4rena
• Audit scoring: Some underwriters assign risk tiers based on audit results, number of audits completed, and whether bug bounty programmes are active
• Audit-firm financial responsibility: Where an audit firm contractually backs its findings (e.g., a payout to a protocol after missing a critical vulnerability), the audit relationship can embed a form of errors-and-omissions coverage, shifting a slice of smart-contract risk onto the auditor

5.3 Proof-of-Reserves as Risk Mitigation

Proof-of-Reserves (PoR) attestations are increasingly relevant to underwriting:

• What PoR demonstrates: That customer crypto assets exist and appear fully backed at a specific snapshot
• What PoR does not demonstrate: Overall financial health, fiat balances, off-chain liabilities, or risks tied to non-custodial business lines
• Underwriting application: PoR attestations by independent auditors can serve as a risk mitigant (reducing premiums or expanding coverage), but must be supplemented by full financial audits

Major exchanges with PoR programmes: Binance, Crypto.com, Kraken, OKX, Bybit, Bitget. However, the exit of Mazars from crypto PoR attestation in 2022 reduced audit quality, and many exchanges now run PoR internally, which undermines independence.

5.4 Tiered Coverage Based on Security Posture

Munich Re's digital asset protection framework illustrates the emerging approach of tiering coverage based on security controls:

• Munich Re Comprehensive Crime Policy: Covers theft from custody, including breaches of external service provider systems. Coverage is conditioned on demonstrated security practices including key management, access controls, and penetration testing.
• Munich Re Smart Contract Risks Insurance: Provides protection against asset loss from smart contract failures, breaches, or exploitations by external parties (a regulated commercial product, notably available in
  Germany where Munich Re is the domestic underwriting champion).
• Munich Re Staking Risk Insurance: Safeguards against slashing risks in proof-of-stake consensus mechanisms.

Regulatory custody tiering reflects the same logic: Canada's CIRO four-tier framework conditions each tier on a combination of holding percentage, fidelity (crime/financial-institution bond) insurance, specie cover for cold storage, and operational resilience — effectively translating "security posture" into a supervised capital/insurance ladder.

5.5 DeFi-Native Insurance Protocols

Decentralised insurance protocols (e.g., Nexus Mutual, InsurAce, Unslashed Finance) represent an alternative risk transfer mechanism. While not actuarially priced in the traditional sense, these protocols use:

• Bonding curve / utilisation-based pricing: Premiums increase as coverage utilisation rises
• Staked capital pools: Token holders stake capital to back coverage, earning premiums
• Claims assessment: Community-based or oracle-driven claims adjudication

Nexus Mutual self-reports a capital pool of roughly US$190 million and approximately US$194 million of active cover (mid-2025), with around US$18 million of claims paid since 2019 (figures self-reported by the protocol). It is a UK discretionary mutual — members have no contractual obligation to pay claims — and is not authorised as an insurer under FSMA, nor MAS-licensed in Singapore.

Limitations for regulatory purposes: DeFi insurance protocols lack capitalisation standards, may not be domiciled in any jurisdiction, and their claims-paying ability is contingent on token prices that may decline precisely when claims surge (procyclical risk). See DeFi Insurance Protocols for the discretionary-mutual versus regulated-insurance distinction.

6. Recommended Actuarial Standards for Regulators

6.1 Data Collection and Reporting

Regulators should mandate that all licensed VASPs report loss events to a centralised database, including:

• Date and time of loss
• Attack vector classification (using a standardised taxonomy)
• Amount lost (denominated in both crypto units and fiat value at time-of-loss)
• Recovery amount and mechanism
• Insurance coverage in place and claim outcome
• Time from loss to discovery
• Security controls that were in place and those that failed

This data would dramatically improve the actuarial credibility of digital asset loss distributions — and would let supervisors validate, rather than assume, the loss outcomes that drive capital charges.

6.2 Minimum Actuarial Standards for Digital Asset Insurers

Regulators should require digital asset insurers to:

1. Disclose modelling methodology: Whether pricing is based on historical experience, scenario analysis, expert judgment, or a hybrid approach
2. Conduct annual stress tests against defined catastrophe scenarios, including at minimum:
   • A state-sponsored attack compromising the largest single insured entity
   • A shared infrastructure failure triggering correlated claims across 30%+ of the portfolio
   • A simultaneous asset price decline of 80% combined with elevated attack frequency
3. Maintain aggregation tracking by shared risk factors: custodian, multisig provider, blockchain, smart contract audit firm, cloud provider
4. Apply explicit loading for parameter uncertainty given the limited data history (minimum 25-50% prudential margin above best-estimate pricing)
5. Re-evaluate at least quarterly given the rapidly changing risk landscape

6.3 Capital Adequacy

Regulators should:

• Treat a 100% stress as a defensible reference point for standard-formula treatment of crypto exposures on insurer balance sheets, while recognising that — as of June 2026 — this is EIOPA technical advice awaiting a subsequent delegated act in the EU and a pending (LegCo-vetting) implementation in Hong Kong, not yet enacted law in either
• Require internal model approval for any insurer claiming a lower capital charge, with enhanced model validation standards reflecting the data limitations
• Set aggregate exposure limits preventing any single insurer from accumulating digital asset exposure exceeding a defined percentage of surplus (e.g., 10-15%), in the spirit of Canada's OSFI cap on insurers' Group 2 crypto exposure (raised from 1% to 5% of Net Tier 1 capital, effective January 2026)

6.4 Valuation Standards

Regulators should mandate:

• Time-of-loss valuation as the default for claims, using verifiable on-chain timestamps
• Maximum detection window of 72 hours between time-of-loss and time-of-discovery for valuation purposes
• Reference price sources from at least three independent exchanges or oracles for valuation
• Stablecoin depeg thresholds defining at what deviation from peg (e.g., >5% for >24 hours) a loss is deemed to have occurred

6.5 Coordination with Banking Regulators

Given the parallel Basel Committee 1,250% risk weight for banks' Group 2b crypto exposures (effective 1 January 2026), insurance regulators should coordinate capital treatment to avoid regulatory arbitrage where crypto risk migrates to whichever sector imposes lighter capital requirements. Canada's OSFI has already published guidance on "Capital Treatment of Crypto-asset Exposures (Insurance)" (revised 29 October 2025, effective January 2026) to align insurance and banking treatment — a model other jurisdictions should follow.

7. Has the Modeling Been Tested in Practice?

For most of the 18 jurisdictions surveyed, the actuarial and capital frameworks above remain untested by a real claim: no loss event has yet exercised Hong Kong's 50%/100% compensation arrangements, and no aggregate claims/loss data is published for the Bermuda or Cayman specialty markets. The one clear proof point is South Korea: in November 2025, Upbit's ~US$28 million Solana-token theft was fully restored through a combination of VAUPA-mandated insurance and reserves — the first publicly reported use of a statutory crypto-insurance mandate to make policyholders whole (after which Upbit raised cold storage to 95%). This single validated event matters for modelling because it confirms that a prescriptive, pre-funded hot-wallet coverage mandate (at least 5% of hot-wallet value, KRW 3 billion minimum for KRW-market exchanges) can actually absorb a mid-sized loss — but it is one data point, at modest severity, and provides no information about how mandated coverage would behave under a Bybit-scale (US$1.5 billion) catastrophe.

Verification Notes

This refresh (4 June 2026) mirrors the canonical per-jurisdiction facts in the digital-asset-insurance fact matrix; no fact outside the matrix or the prior version of this file has been introduced, and market-capacity, premium, and coverage figures are flagged as self-reported. No web searches were performed for this refresh — the matrix is the verified source of truth. Earlier regulatory references, capital-treatment figures, and modelling frameworks were verified through web searches conducted on 20 March 2026 (EIOPA, BIS/Basel Committee, Lloyd's RDS, Munich Re, Chainalysis, IAIS, OSFI).

Key facts refreshed this cycle:

• Hong Kong IA's RBC consultation conclusions (8 May 2026) confirm a 100% downward stress on insurers' crypto holdings, with stablecoin look-through + counterparty overlay; implementation targeted 31 December 2026 pending LegCo negative vetting
• Basel Group 2b 1,250% risk weight effective 1 January 2026
• IAIS final Application Paper on Operational Resilience Objectives and Toolkit published 12 February 2026 (no crypto-specific provisions)
• OSFI raised insurers' Group 2 crypto exposure cap from 1% to 5% of Net Tier 1 capital (effective January 2026)
• Aggregate theft: ~US$3.41 billion in 2025 (Chainalysis); Bybit ~US$1.5 billion (21 February 2025); Q1 2026 ~US$168.6 million, down ~88% YoY (self-reported/preliminary)
• South Korea Upbit November 2025 restoration via VAUPA insurance + reserves — first validated use of a statutory crypto-insurance mandate
