Ethereum (ETH) London Hard Fork and Its Impact on BitMEX ETHUSD Perpetual, ETHUSDU21, and ETHU21 Futures Contracts

The Ethereum network is scheduled to undergo the London Hard Fork on August 5, 2021. This upgrade will affect three BitMEX contracts—ETHUSD Perpetual, ETHUSDU21, and ETHU21 Futures—alongside two BitMEX indices (.BETH and .BETHXBT). All markets will remain operational during the fork.

Impact on BitMEX Indices

BitMEX’s .BETH and .BETHXBT indices are constructed using the following constituent exchanges and weightings:

Index Binance Binance US Bitstamp Coinbase FTX Huobi Gemini Kraken OKEx Poloniex
.BETH 3.83% 9.08% 50.86% 16.38% 4.77% 15.08%
.BETHXBT 70.51% 6.69% 10.36% 3.61% 6.19% 2.64%

As of this announcement, no constituent exchanges have indicated plans to suspend ETH spot trading during the fork. BitMEX will monitor exchanges closely and remove any from the index if they pause ETH markets, aligning with their published schedules.

Key Considerations for Traders

  • Increased Volatility: Expect heightened price fluctuations during the fork.
  • Risk Management: Adjust positions and leverage to mitigate potential risks.
  • Index Adjustments: BitMEX reserves the right to modify indices swiftly to ensure market stability.
