Key Highlights
- Arthur Hayes says the October 10 crash began on Binance due to a margin-marking flaw, not a coordinated scheme by CZ or market makers.
- A thin-liquidity exploit, cascading liquidations, and a Binance API outage caused altcoins to plunge 85–90% within minutes.
- Hayes expects no 2022-style contagion but warns that traders are now fearful, liquidity is thin, and confidence will take time to recover.
In a recent podcast appearance, BitMEX Co-Founder Arthur Hayes offered a detailed breakdown of the violent October 10 crypto market crash, rejecting conspiracy theories and instead pointing to a structural flaw in Binance’s margin-marking system that spiraled into a full-blown liquidity crisis.
Addressing the rumors circulating online, Hayes said the collapse “started on Binance for some idiosyncratic reasons,” but firmly denied that it resulted from a coordinated attempt by Binance Co-Founder Changpeng Zhao (CZ) or market makers to manipulate prices.
He pushed back against the idea of a “cabal of market makers” devising a secret plan to wipe out traders, saying the truth was far more mundane: traders simply did not understand the rules of the exchange they were using.
“There are a bunch of rules that every exchange operates under and they publish documents that nobody reads,” Hayes said, explaining that many traders only pay attention to these details once something breaks. In his view, this was one of those moments.
A margin-marking quirk triggered the cascade
Hayes explained that the root of the crash lay in how Binance handled cross-collateral margin positions. The exchange marked certain stablecoins and assets like Ethereum to its own internal markets, which were far less liquid than global venues such as Curve. This created an opening for an attacker to move prices with relatively small amounts of capital.
According to Hayes, someone exploited that thin internal liquidity. By dumping a modest amount of funds, they triggered an outsized price collapse in Binance’s margin collateral markets. That first price drop triggered a chain reaction of forced liquidations across Binance.
As the exchange began closing out positions, market makers rushed to pull back their own liquidity to protect themselves, which only made the order books thinner and the sell-off even more violent.
At the worst possible moment, Binance was also hit with an API outage. Traders suddenly couldn’t see their positions or place orders, leaving them completely blind as prices went into freefall. With virtually no liquidity left and forced selling accelerating on its own, many altcoins collapsed by 85% to 90% within minutes.
DeFi leverage structures crumbled as well
The damage wasn’t limited to centralized trading platforms. Hayes said that looping strategies on decentralized finance (DeFi) protocols, where traders stacked leverage on top of leverage, were wiped out instantly when collateral values plunged.
Several lending protocols suffered major failures, traders running delta-neutral strategies lost money across venues, and a number of market-making firms absorbed heavy losses after misjudging how Binance’s systems handled collateral.
The combined impact removed a significant amount of liquidity from the broader crypto market, pushing weaker assets toward zero and exposing how dependent many tokens are on paid market makers rather than organic demand.
Hayes doesn’t expect a 2022-style chain reaction
While the October 10 collapse revived memories of the contagion that began with Luna in 2022 and eventually toppled firms like 3AC and FTX, Hayes does not believe the industry is on the verge of another multi-month unwind.
He noted that although some smaller DeFi platforms may still harbor hidden vulnerabilities, he doesn’t expect major protocols to suffer catastrophic failures.
Instead, Hayes warned of a different kind of fallout: fear. “I think what’s going to affect is it’s going to cause a lot of traders to be very tepid in getting back into the market,” he said. He pointed out that many traders have now seen the “real value” of certain tokens, “basically close to zero”—once artificial liquidity disappears.
A market left cautious and thin
Hayes believes the biggest lingering effect of the crash will be psychological. With so much capital destroyed and confidence damaged, traders may hesitate to re-enter, even if prices attempt to recover. That hesitation, combined with the liquidity that was withdrawn during the crash, leaves the market vulnerable.
For now, he sees no grand conspiracy, just a familiar combination of misunderstood exchange mechanics, excessive leverage, and structural fragility. And, as Hayes noted bluntly, crypto traders once again paid the price for not reading the rules.
