BNB is the token at the centre of Binance's ecosystem, used for trading-fee discounts and as the fuel of BNB Chain, so its price carries a view on the exchange itself. On the afternoon of Thursday, October 29, it gave no sign of what was coming: it touched $754.29 in the 16:00 UTC quarter-hour, then drifted lower in small steps to $744.89 at 19:45, on quarter-hours mostly worth $400,000 to $800,000. The wider market was waiting for Amazon, Intel and Coinbase, which reported after the US close at 20:00 UTC.
The first two quarter-hours after 20:00 were weak but orderly: −0.68% to $739.84 on $5.36 million, then −1.10% to $731.69 on $9.58 million. The 20:30 candle was the break. It fell from $731.70 to a low of $689.00 and closed at $692.92, down 5.30% on $49.4 million and 120,380 trades, about 105 times the volume of the 19:45 quarter-hour, and the 20:45 candle reached $680.00, 8.7% below the pre-report price. According to Reuters, citing TRM Labs and Chainalysis, most of the theft took place over about 20 minutes late on Thursday; Binance's confirmation that it had suspended withdrawals reached the press later, with TechCrunch's report published at 22:27 UTC. The exchange put the total impact at about $6.3 billion, of which roughly $3 billion was frozen, and Glassnode said Binance's own BNB balance had been left untouched.
The rebound was almost as fast as the fall. The 21:00 quarter-hour rose 1.90% to $711.26 on $28.7 million, and the 21:15 candle reached $726.84, 6.9% above the low. It did not last: the token slipped to $705.92 by 21:30 and $698.46 by 23:45, and the 00:15 UTC candle on Friday fell 1.60% to $684.06, with a low of $682.16, on $19.3 million. That second test came while Binance was telling users they would not bear the losses, which it said it would cover from its SAFU emergency fund and its own money, and while Tether and Circle froze more than $2.3 billion of stablecoins linked to the attack.
The second low held $2.16 above the first, on less than half the volume of the 20:30 candle, and the selling faded from there. By 02:15 UTC the token was back at $714.68, it reached $720.00 in the 03:45 quarter-hour and ended the replay at $717.49, 3.7% below Thursday evening, after $342.8 million had changed hands in fourteen hours. The night shows how an exchange token works as a live verdict on the exchange: the price fell fastest before the full picture was public, recovered when the scale of the frozen funds and the promise to cover losses became clear, and settled at a discount that reflected the question still open, when withdrawals would reopen.
