A quiet consultation from a major index provider may have crippled a core engine of the crypto bull market, explaining the persistent market depression following October's historic crash.
For weeks, the cryptocurrency market has felt broken. Following the single largest liquidation event in its history on October 10th, which saw Bitcoin, Ethereum, and altcoins plummet, every subsequent attempt at a recovery has faltered. While initial blame was placed on macro shocks—specifically former U.S. President Donald Trump's announcement of 100% tariffs on all Chinese imports—these factors alone fail to explain the market's persistent inability to mount a sustained rally.
Emerging as a critical piece of this puzzle is a document published quietly on that same fateful day by MSCI, the world's second-largest index provider. This consultation paper directly targets Digital Asset Treasury companies (DATs), the publicly-listed vehicles like Michael Saylor's Strategy (Nasdaq: MSTR) that have been pivotal buyers this cycle. The revelation that one of crypto's largest marginal buyer groups faces potential structural impairment by early 2026 has cast a long shadow over market sentiment, transforming a violent sell-off into a prolonged period of stagnation.
Digital Asset Treasury Companies: The TradFi Bridge
DATs are publicly-traded entities whose primary business is holding bitcoin or other digital assets on their balance sheet. Pioneered by what was then called MicroStrategy with its initial purchase of 21,454 bitcoin in August 2020, these vehicles raise capital—through equity, debt, or convertible instruments—in traditional markets and deploy it to acquire cryptocurrencies. In doing so, they provide traditional finance (TradFi) investors with a leveraged, publicly-listed proxy for digital asset exposure.
In the current market cycle, DATs have evolved into one of two major structural buyers of digital assets, alongside spot Bitcoin ETFs and related passive vehicles. Their significance extends beyond simple accumulation; they have become integral to a self-reinforcing "flywheel" effect powered by index inclusion.
The Index Inclusion Flywheel
The mechanism is powerful and cyclical:
This flywheel has turned DATs into a critical conduit, transforming traditional equity capital into direct, incremental demand for underlying assets like Bitcoin. MSCI's October 10th proposal threatens to cut the power to this entire engine.
Proposed Reclassification: From Company to Fund
On October 10, 2025, MSCI published a consultation titled “Digital Asset Treasury Companies.” The core proposal is to reclassify companies whose primary business is holding bitcoin or other digital assets as fund-like vehicles rather than operating companies. Crucially, the consultation suggests that if a firm’s digital asset holdings represent 50% or more of its total assets, it could be excluded from MSCI’s main equity indexes.
The timeline is set: the consultation remains open until December 31, 2025. A final decision is scheduled for January 15, 2026, with any resulting exclusions implemented as part of the February 2026 index review.
Quantifying the Potential Impact
The potential capital outflow is significant. Analysts at JPMorgan estimated that removing a flagship DAT from MSCI indexes could trigger approximately $2.8 billion in forced passive selling. This figure could balloon to as much as $8.8 billion if other major index providers follow MSCI’s lead and adopt similar exclusion rules.
This represents a fundamental shift from headline risk to structural risk. Index trackers, pension funds, and other passive vehicles would be compelled to sell these stocks not due to a view on Bitcoin, but because their investment mandates require strict adherence to index composition rules. Furthermore, future DATs would lose eligibility for passive index inclusion altogether, akin to how funds and ETFs are treated.
The day's events formed a perfect storm of overlapping crises:
This sequence suggests that while macro forces ignited the sell-off, the looming structural threat to a key buyer cohort has fundamentally altered the market's appetite to "buy the dip."
The potential exclusion of DATs from major indices is not merely a stock-specific issue; it attacks a core mechanism of capital inflow during this cycle.
DATs function as a vital bridge. Many institutional allocators—including passive funds and pension plans—face regulatory or operational constraints preventing direct cryptocurrency purchases. However, they can freely invest in broad market indices. When those indices contain a DAT, traditional capital is indirectly funneled into crypto. The DAT then leverages that equity value to buy more bitcoin, effectively multiplying the impact.
MSCI's move threatens this pipeline in three concrete ways:
This overhang has recalibrated market psychology. Savvy participants are now evaluating every price dip against the known risk of significant forced selling in early 2026, creating a persistent ceiling on bullish enthusiasm.
Since the October crash, three aligned forces have suppressed any meaningful recovery:
The result is a market characterized by sharp but fleeting rallies that quickly meet a wall of supply from sellers who are hedging, de-risking, or locking in losses. New buyers remain hesitant amid the uncertainty, while one of the previous cycle's most reliable buyers—the DATs themselves—operates under a cloud of existential threat.
The market narrative now converges on MSCI’s decision date of January 15, 2026, from which two broad scenarios emerge:
Scenario 1: Negative Outcome & Exclusion If MSCI classifies DATs as "funds" and excludes them from core indexes, we can expect:
Scenario 2: Positive or Nuanced Outcome If MSCI decides against exclusion or adopts a more nuanced framework that allows DATs to remain in benchmarks:
The events of October 10th delivered two stark lessons to crypto investors. First, cryptocurrency markets remain acutely vulnerable to exogenous macro shocks, as demonstrated by the tariff-induced liquidation cascade. Second, and perhaps more importantly, market structure is fragile and subject to change by seemingly distant TradFi rulemakers like MSCI.
For investors navigating this environment until mid-January:
The Future of DATs: Evolution Over Extinction
Even in a negative outcome where DATs are excluded from indices their model is unlikely to vanish entirely; instead it may evolve from Digital Asset Treasuries into Digital Asset Companies (DACs). Without the index-inclusion flywheel these entities would need to generate real incremental value beyond simple asset accumulation This could involve using their access public capital markets build products services or infrastructure that support broader ecosystem growth—akin early ecosystem supporters like Consensys did for Ethereum
Ultimately October wasn't random crash It was day market discovered foundational mechanism powering its rally was under formal review signaling new phase convergence between crypto traditional finance where rules governing indices can have profound downstream effects on digital asset prices
