As of the week prior to May 18, 2026, CoinShares reported a net outflow of approximately $1.07 billion from institutional digital asset investment products, which directly ended a trend of net inflows that had persisted for six consecutive weeks, marking a phase reversal in capital direction. Among these, Bitcoin-related products saw a net outflow of about $982 million, becoming the absolute main force in this adjustment; Ethereum-related products recorded a net outflow of approximately $249 million, the largest single-week outflow since January 30, 2026. This week also counted as the third largest single-week net outflow event in 2026 to date, with total assets under management (AUM) decreasing from about $159 billion to around $157 billion, shrinking by approximately $2 billion. More critically, CoinShares and several reports citing this data pointed out that this wave of capital withdrawal was mainly driven by U.S. investors and U.S.-registered digital asset investment products. Such compliant products that exist in the form of funds, ETPs, trusts, etc., regulated by the SEC and requiring adherence to KYC/AML and information disclosure rules, provide a new sample for observing institutional behavior under pressure scenarios within a regulatory framework.

U.S. Registered Crypto Products Become the Main Battleground for Sell-Offs

Examining the structure of this approximate $1.07 billion single-week net outflow, the capital withdrawal was highly concentrated among U.S. investors and U.S.-registered digital asset investment products, effectively placing the "brake pedal" on regulated compliant channels. CoinShares data and related reports indicate that this week the outflow was primarily driven by the U.S. market, where U.S. registered products often exist in forms such as funds, ETPs, trusts, etc., which are regulated by financial regulatory agencies like the SEC and must fulfill compliance obligations such as KYC/AML, information disclosure, and custody. For institutions constrained by capital and compliance, in scenarios where geopolitical and macro risks are intensifying, and assets like Bitcoin and Ethereum are re-evaluated as "high-risk exposures," the most feasible and lowest compliance cost action is to prioritize reducing positions through these regulated products rather than turning to over-the-counter or opaque channels.

This structural preference also explains why, whenever risk appetite shifts, the redemption data of U.S. compliant products is often the first and clearest to emerge in weekly reports. In this event, the $1.07 billion net outflow, with about $982 million flowing out from Bitcoin products and around $249 million from Ethereum products (the largest since January 30), combined with the total AUM decreasing from approximately $159 billion to about $157 billion, constitutes a complete sample for regulators to observe capital behavior under pressure scenarios: on one hand, the custody and information disclosure constraints on these products make the flow of funds highly visible, facilitating statistics and risk monitoring; on the other hand, without any information on systemic liquidity interruptions or custody incidents publicly reported, these products also verify the resilience of the existing compliance framework under real market pressure, making them appear more like a "viewing window" continuously quantifying institutional risk appetite changes rather than merely trading tools.

Iran Tensions and Compliance Risk Control: Institutions Forced to Reduce Risk

Multiple media outlets quoting CoinShares' weekly report linked this round of approximately $1.07 billion single-week net outflow to the escalation of geopolitical risks, especially tensions related to Iran, suggesting that this external shock combined with rising global risk aversion is a key variable triggering a "unified reduction" in positions among institutions. In the same week, Bitcoin products recorded net outflows of about $982 million, while Ethereum products saw about $249 million in net outflows (the largest since January 30, 2026), leading to a drop in total AUM of compliant digital asset products from approximately $159 billion to about $157 billion, reflecting the concentrated withdrawal path of funds under risk compression in the short term.

From the perspective of compliance and risk management, the long-standing sanctions framework imposed by the U.S. and its allies on Iran often compels institutions bound by SEC and other regulatory compliance requirements to prioritize the reduction of high-volatility positions such as stocks, credit, and crypto assets during sudden escalations of relevant situations through stress testing and internal risk limit mechanisms. U.S.-registered digital asset investment products exist in the forms of funds, ETPs, trusts, etc., which must adhere to KYC/AML, custody, and information disclosure obligations. Under capital adequacy and risk limit constraints, they have been "programmatically" treated as high-risk assets in this round of events, rather than any kind of safe-haven tools. The $1.07 billion single-week net outflow provides regulators with a clear sample: under pressure scenarios, crypto-related exposures are systematically prioritized for reduction, reinforcing their classification as "high-risk assets rather than safe-haven assets" in regulatory and institutional contexts, while increasing the probability that they will be assigned higher risk weights in future capital occupation, risk disclosure, and investor suitability regulations.

Simultaneous Outflows from Bitcoin and Ethereum, Safe-Haven Narrative Under Pressure

Examining asset classes, among this week’s approximate $1.07 billion net outflow, Bitcoin-related products alone accounted for about $982 million, and Ethereum products saw a net outflow of approximately $249 million during the same period, setting a record for the largest single-week outflow since January 30, 2026. This indicates that the two major assets did not exhibit a divergent pattern of "one being treated as a safe-haven asset attracting capital while the other being sold off," but rather were reduced in positions simultaneously by institutions. Under the previous narrative that "Bitcoin = digital gold," this set of data provides a stark contrast: from the beginning of 2026 to now, Bitcoin products have seen a cumulative net outflow of about $3.9 billion (from a single source), and this week, in a pressure scenario, they continued to see a substantial reduction in allocation, with the capital behavior at the mainstream compliant product level compressing the "safe-haven" label into a narrative that primarily exists in promotional and emotional contexts.

From a regulatory and compliance perspective, this simultaneous outflow result is highly consistent with existing frameworks: under the regulatory and accounting rules in most jurisdictions, Bitcoin and Ethereum are classified as high-risk, non-interest-bearing assets, rather than as government bonds or cash equivalents. Banks and brokerages generally apply higher risk weights when assessing related exposures, and this week’s concentrated redemptions provide a new sample for stress testing this classification. For regulators, this round of outflow events reinforces a key signal: mainstream crypto assets are viewed in practice as risk assets by institutions, rather than as assets that can automatically provide protection in times of crisis. In the future, it is expected that this data will be referenced in discussions surrounding three major aspects—first, to continue maintaining or even refining high-risk weight classifications under capital occupation rules without opening separate criteria for so-called "digital gold"; second, requiring products to clearly state the historical performance of crypto assets and other high-volatility assets undergoing redemptions under macro and geopolitical shocks in risk disclosures; and third, strengthening the classification of "high-risk, non-safe-haven" in investor suitability, making it more difficult for these products to be packaged as robust hedging tools in compliance sales and asset allocation discussions.

AUM Shrinks by $2 Billion: Custody and Liquidity Face Tests

Under the pressure of approximately $1.07 billion in net outflow, the total assets under management (AUM) of related products decreased from roughly $159 billion to about $157 billion, shrinking by approximately $2 billion, presenting a concentrated "stress test" for product managers, custodians, and market makers. The concentrated capital redemptions amplified the transaction volume and spreads in the underlying spot and derivatives markets, requiring market-makers and liquidity providers to continually provide secondary market liquidity for regulated funds and ETPs in an environment of widened spreads and reduced order depth while collaborating with product managers to complete redemption hedging and position adjustments between primary and secondary markets, testing their operational capacity to handle short-term shocks under compliance constraints.

At the institutional level, regulated funds and ETPs, when facing such large outflows, must ensure fair valuation of product shares to protect the interests of remaining investors from significant intraday price volatility or poor liquidity of certain underlying assets; they must also respond to peak redemption periods according to established liquidity management policies, assessing whether to control shock costs through temporary adjustments to redemption rhythms, optimizing trading pathways, etc. When hitting thresholds for "significant events," they are also required to fulfill information disclosure obligations, enabling regulators and investors to timely understand the operational status of products. Correspondingly, digital asset custody institutions must strictly implement security and compliance processes in managing cold and hot wallets and on-chain operations when processing large-scale asset transfers within a short timeframe, ensuring timely redemption receipt while avoiding "speeding up with reduced controls." As of now, there have been no public reports of systemic liquidity interruptions or custody incidents caused by this round of capital outflows, indicating that under the existing regulatory framework and technical conditions, compliant market infrastructure has basically withstood a moderately intense concentrated redemption shock.

Next Steps for Regulators, Platforms, and Institutions

This round of approximately $1.07 billion in single-week net outflow is both the third largest event since 2026 and disrupted a six-week streak of net inflows, clearly showcasing the "high-risk asset" attributes of compliant digital asset products against the backdrop of escalating geopolitical tensions: capital rapidly withdrew under macro and geopolitical pressures, primarily through channels such as U.S.-registered funds, ETPs, and trusts regulated by the SEC. This provides regulators with a quantifiable pressure scenario sample. The Bitcoin and Ethereum products recorded outflows of approximately $982 million and $249 million respectively, contrasting starkly with the narrative of "digital gold" and "safe-haven assets," reinforcing the necessity of treating these assets as high-volatility and high-risk in regulatory classifications, capital occupation, and risk disclosure discussions. For platforms and product issuers, this scale of concentrated redemptions implies that risk disclosures need to present withdrawal paths under geopolitical events more transparently, refine layers of risk tolerance management in investor suitability, and incorporate similar levels of $1 billion in fund flows into conventional liquidity and operational stress testing benchmarks. For institutional investors and their compliance teams, the signal from this event is: in asset allocation, investment committee memos, and external roadshow materials, they should downplay the "safe-haven" narrative and strengthen consistency with regulatory high-risk classifications, treating these products as volatile assets that require meticulous management under risk budgets and internal limits rather than as insurance policies that automatically provide protection amid geopolitical shocks.
