The margin requirements for BCHUSD contracts will be increased from 2% (50x) to 4% (25x) for positions up to 100k contracts at 2020-11-14 1700 UTC. Please see the margin schedule for full details - https://support.kraken.com/hc/en-us/articles/360022632452-Margin-schedule-and-maximum-leverage
For technical background, please view the Kraken Blog post.
We will take a snapshot of all BCH client balances on Kraken Futures (including realized and unrealized PnL) at the time of the last common block right before the fork. If the criteria for Kraken to support Bitcoin Cash ABC is met, the equal amount of Bitcoin Cash ABC (as determined by the snapshot) will be credited to client's Kraken spot account.
We currently offer access to the Crypto Facilities BCHUSD Futures contracts; a Perpetual BCH:USD Futures, settling on the CF Bitcoin Cash-Dollar Spot Rate as well as a Monthly and Quarterly BCH:USD Futures, settling on the CF Bitcoin Cash-Dollar Settlement Price. Both indices are calculated based on BCH spot data from Bitstamp, Coinbase, Gemini and Kraken.
These contracts will settle to the CF Bitcoin Cash Dollar Spot Rate and CF Bitcoin Cash Dollar Settlement Price as determined by the Index Administrator - CF Benchmarks. In the event that CF Benchmarks launches an emergency benchmark index - as triggered by the provision in Section 4.2 of the CF Cryptocurrency Index Family Hard Fork Policy and this benchmark continues to be available at the time of contract settlement, then positions in the Perpetual BCH:USD futures as well as the Monthly and Quarterly BCH:USD Futures will settle to the sum of the benchmark indices.
Note that if the settlement rate reported by the Index is, for any reason, deemed to not adequately represent the underlying market, the Mark Risk Committee of Crypto Facilities reserves the right to select its own appropriate fair value settlement rate.
