"10/10 was caused by irresponsible marketing campaigns by certain companies." — Star Xu, CEO, OKX (January 31, 2026)
One year ago, on October 10, 2025, the cryptocurrency market suffered its worst single-day liquidation in history. Over $19 billion in leveraged positions were forcibly closed within 24 hours. More than 1.6 million trading accounts were wiped out. At the peak of the cascade, $3.21 billion vanished in 60 seconds. The trigger was a tariff announcement. The accelerant was a market structure that priced collateral reflexively against its own order books, permitted multi-asset cross-margining on volatile synthetic tokens, and offered retail leverage of up to 125x.
Twelve months later, the market sits at $81,600 per BTC — 33% below its pre-crash peak of $121,000 — and is reliving the same week under a new set of macro pressures. On October 7, 2026, $403 million in long positions were liquidated in a single hour. On October 8, U.S. spot Bitcoin ETFs recorded $487 million in net outflows, the largest since June. Brent crude sits at $105 per barrel. The Fed minutes signal further rate hikes. The question is not whether 10/10 can repeat. The question is whether the market's post-crash reforms are sufficient to prevent the same amplification mechanics from producing the same result.
At 14:57 UTC on October 10, 2025, President Trump announced 100% tariffs on all Chinese imports along with new export controls on critical software. Bitcoin traded at $121,000. Within minutes, selling pressure built across all risk assets. At 20:50 UTC, the liquidation cascade began.
According to analysis by Amberdata, $3.21 billion in positions were liquidated in the first 60 seconds. Over the following 40 minutes, $6.93 billion in positions were forcibly closed — a rate of $10.39 billion per hour, compared to $0.12 billion per hour in the preceding eight hours. Seventy percent of total damage occurred in that 40-minute window.
By the time the cascade ended 14 hours later, $19 billion in leveraged positions had been wiped across centralized exchanges. Bitcoin fell from $121,000 to $107,000. Ethereum fell to $3,551. Solana dropped to $174. Open interest across crypto futures markets contracted 43%, including a 57% decline on Hyperliquid. Order-book depth on BTC shrank more than 90% on key venues. Bid-ask spreads widened from single-digit basis points to double-digit percentages at extremes.
The event was approximately nine times larger than the worst single-day liquidation during the 2022 crash.
According to a post-mortem by FTI Consulting, the crash was not caused by fraud, insolvency, or the failure of a single institution — distinguishing it from the Terra/Luna and FTX collapses. Instead, it resulted from the convergence of three structural factors.
Leverage positioning. By early October, perpetual futures funding rates had climbed from approximately 10% annualized to nearly 30% by October 6, driven by an Ethereum rally. Open interest was elevated and concentrated in one direction.
Unified cross-margin mechanics. Major exchanges operated unified margin systems that tied portfolios to their weakest constituent asset. When synthetic collateral tokens — particularly USDe — dropped in value on Binance's spot order book, traders using USDe as cross-margin collateral saw their entire portfolio equity recalculated downward, triggering liquidations across unrelated positions.
Reflexive collateral pricing. Leveraged products priced collateral using the venue's own spot price. When Binance's order-book-derived price for USDe fell to approximately $0.60 — a 35% discount to peg — the platform's own thin book set the collateral value, which triggered liquidations, which generated more selling, which pushed the price lower. USDe maintained closer-to-peg pricing simultaneously on other exchanges and DeFi pools. The depeg was venue-specific; the liquidation cascade was market-wide.
Automatic deleveraging (ADL). Exchange ADL mechanisms forcibly closed profitable positions to maintain solvency, spreading losses to traders who had not been liquidated, eroding confidence, and amplifying the sell-off.
The dispute over causation has not resolved. OKX CEO Star Xu blamed Binance's 12% APY campaigns on USDe for creating leveraged loops in which traders converted stablecoins to USDe, farmed yield, and used USDe as collateral to borrow more — a cycle he called "irresponsible." Binance and Ethena countered that USDe "clearly can't have caused the liquidation cascade" because the depeg was isolated to Binance's own order book.
The 12 months since 10/10 have produced a set of incremental reforms. None constitutes a structural overhaul.
Collateral pricing methodology. Binance incorporated USDe's redemption price into its reference index and established a soft price floor. Exchanges no longer rely solely on their own spot order books to determine collateral values and have shifted toward multi-source, on-chain oracle feeds. According to LlamaRisk's analysis, this represents the most consequential change: venue-specific dislocations can no longer set collateral values unilaterally.
Index methodology. Binance rebuilt its index methodology by adding redemption prices to the index weights for USDe, WBETH, and BNSOL, and introduced a minimum USDe price threshold and tighter deviation guards.
Collateral haircuts. Several major venues increased discounts on synthetic and illiquid collateral and lowered maximum leverage on selected trading pairs. Specifics vary by exchange and have not been uniformly disclosed.
Regulated perpetual futures. On May 29, 2026, the CFTC approved the first regulated U.S. Bitcoin perpetual, the BTCPERP contract, listed by Kalshi. Ethereum launched June 4. XRP launched June 10. All are USD-settled. Margin sits with Kinetics FCM in customer-segregated accounts. Clearing runs through Kalshi Klear, a CFTC-regulated clearinghouse. The design limits leverage, includes volatility controls, and permits isolated margin only. According to CoinDesk, centralized exchanges processed $86.2 trillion in perpetual futures volume in 2025 — all of it on offshore platforms. Kalshi's contracts represent the first domestic, CFTC-regulated alternative.
Compensation. Binance is the only major exchange to have announced compensation for affected traders. Details of the program's scope and payout remain limited in public disclosures.
Offshore leverage limits remain high. Retail users on offshore exchanges can still access leverage of 50x to 125x on perpetual futures. The CFTC's proposed Regulation CTX and Regulation CAM, released October 5, 2026, would create a voluntary federal registration category for crypto exchanges offering retail leverage products, but the rulemaking is in comment period and years from implementation. The CLARITY Act failed a Senate cloture vote 49–50 on September 15, 2026.
Unified margin is still the default. Most major centralized exchanges continue to operate unified cross-margin systems. Isolated margin remains available but is not the default. Cross-margin mechanics still expose portfolios to contagion across uncorrelated positions when a single collateral asset reprices sharply.
Market maker liquidity commitments are informal. The October 10 crash revealed that visible liquidity — $103 million in order-book depth at 0.02 bps spread pre-crash — evaporated when needed. According to CoinDesk, market makers withdrew in the first minutes of the selloff. A BitMEX analysis published January 2026 found that market makers were "stuffed with coins" for months after the crash, slowing recovery. No major exchange has disclosed binding market-maker obligations or circuit breakers comparable to traditional equity markets.
No circuit breakers. Traditional equity markets have had automated trading halts since the 1987 crash. No major crypto exchange has implemented comparable circuit-breaker mechanisms that would pause trading during cascading liquidations.
The current selloff is occurring in the same calendar week as last year's crash, under a different macro configuration but a similar leverage structure.
Price. Bitcoin traded at $81,625 on October 8, 2026, down from a local high near $87,000 on October 3. Ethereum has declined in tandem.
Liquidations. On October 7, $403 million in long positions were liquidated in a single hour as Bitcoin fell toward $84,100. On October 3, $433 million in long liquidations occurred following an $87,000 rejection.
ETF flows. U.S. spot Bitcoin ETFs recorded $487 million in net outflows on October 7, the largest since June 25. BlackRock's IBIT led with $207.7 million, Fidelity's FBTC with $105.1 million, and ARK 21Shares' ARKB with $101.7 million. The outflows erased October's $321.6 million in prior net inflows.
Open interest. Aggregate Bitcoin futures open interest stands near $47.75 billion. According to CCN, Bitcoin open interest climbed 4% in seven days heading into the anniversary, compared with 4.1% in the week before the 2025 crash.
Funding rates. The average funding rate is +0.0069% per eight-hour period, with the predicted rate at +0.0074%. Four days prior, funding was negative at −0.0043%. By comparison, funding rates were near 30% annualized in the week before 10/10/2025. Current rates indicate less aggressive directional speculation than one year ago.
Macro backdrop. Brent crude trades at $105.21 per barrel. Fed minutes released October 8 signal the possibility of further rate hikes. The combination of energy costs, rates, and geopolitical uncertainty in the Middle East has created a risk-off environment across asset classes.
Structural difference. One signal suggests positioning may be less fragile than 2025: perpetual futures open interest fell 5.7% while dated futures (30OCT26 contracts) open interest rose 55.5%, according to Bit.com research. Leverage is migrating to dated contracts, which do not force chain-reaction closure through the same funding-rate mechanics as perpetuals.
The 12 months since October 10, 2025, have produced a set of reforms best described as partial. Collateral pricing is less reflexive. Index methodology is tighter. A regulated domestic perpetual exists for the first time. These changes matter at the margin.
The core architecture has not changed. Retail leverage of 50x or more remains available offshore. Unified cross-margin systems still permit contagion across uncorrelated assets. No major exchange has implemented circuit breakers. Market-maker obligations remain unwritten.
Current market conditions do not mirror October 2025 exactly. Funding rates are materially lower, suggesting less crowded directional positioning. But open interest is rebuilding into a falling market, ETF investors are exiting at the fastest rate in four months, and the macro backdrop — oil above $105, potential rate hikes — is applying pressure that did not exist a week ago.
The October 10 crash demonstrated that crypto market infrastructure can amplify a macro shock by an order of magnitude through leverage, reflexive pricing, and the absence of trading halts. Whether the same amplification mechanics activate this week depends on positioning that is not fully observable from public data. What is observable is that the structural conditions enabling such amplification remain largely intact.
