Key Summary
- The SEC has approved Nasdaq PHLX to list Bitcoin index options, with cash settlement, European exercise, and a position limit of 24,000 contracts.
- Tracking the CME CF Bitcoin Real Time Index, a single contract has a notional value of approximately $76,000, and the settlement price is in BRRNY.
- Unlike ETF options such as IBIT, investors can trade BTC price exposure without holding spot or ETF shares.
Since the launch of IBIT options in late 2024, US investors wanting to bet on Bitcoin using options had to go through an ETF as an intermediary. The SEC's approval on May 22nd eliminates this intermediary layer.
Nasdaq PHLX has been approved to list Nasdaq Bitcoin Index Options, allowing investors to bet directly on the Bitcoin price index without touching the spot market or ETFs, with cash settlement on the maturity date.
CME pricing, European-style exercise, annual settlement
This option tracks the CME CF Bitcoin Real Time Index (BRTI) divided by 100, and the settlement price is BRRNY (CME CF Cryptocurrency Reference Rate New York variant) also divided by 100, officially named BRRNY-NOS.
BRRNY calculates daily trading data in sync with the US financial market closing time at 4 PM, 365 days a year, aggregating transaction data from multiple exchanges that comply with CME CF standards.
The contract uses a European-style exercise (exercise only on the expiry date), is cash-settled, and involves no physical delivery of Bitcoin or ETF shares. The position limit is 24,000 contracts, the minimum price unit is $0.01, and it follows the Penny Interval Program in sync with IBIT options. Based on the index level at the end of April, the notional value per contract is approximately $76,000. It's purely an index bet.
Expanding the Derivatives Market
In October 2024, the SEC approved IBIT to launch options on Nasdaq. In the same month, the NYSE and CBOE obtained options licenses for 11 Bitcoin spot ETFs. Subsequently, the NYSE removed the position cap on crypto ETF options, allowing products like IBIT to compete on par with traditional commodity ETFs.
CME also announced that it will launch Bitcoin volatility futures on June 1, allowing traders to directly bet on the price swings of BTC rather than its direction.
Index options fill another gap. ETF option prices are influenced by factors such as the ETF's premium/discount, redemption mechanisms, and position limits. Index options, on the other hand, are directly pegged to the CME's benchmark index, resulting in a cleaner structure. For institutions, this provides an additional hedging channel that bypasses ETF intermediaries.
Frequently Asked Questions
What are the differences between Nasdaq Bitcoin Index options and IBIT options?
IBIT options are based on the iShares Bitcoin Trust ETF, and their prices are affected by the ETF premium or discount. Index options directly track the CME CF Bitcoin Index, are cash-settled, and do not involve physical delivery of ETFs or Bitcoin, resulting in a simpler structure and lower transaction costs.
Can Taiwanese investors trade Nasdaq Bitcoin index options?
You must open an account through an overseas brokerage firm with a U.S. options trading license (such as Interactive Brokers). Taiwanese sub-brokerage firms typically do not support U.S. stock index options; you need to confirm the product range and eligibility criteria of individual brokerage firms.
