Ether Futures Frequently Asked Questions

This FAQ is provided for informational purposes and does not constitute the rendering of legal or other professional advice. Individuals and entities should in all cases seek advice from their independent legal and professional advisors regarding the matters discussed below.


Why is CME Group launching Ether futures?

As with any new product or service, we made the decision to launch Ether futures based on strong customer demand and a clearly articulated customer need.

Today, ether is the second largest cryptocurrency by both market capitalization and daily volume. Ether futures on a regulated, time-tested exchange can offer a way for investors to hedge risk exposure in the ether cash market – we’re creating a forward curve so investors can better manage price risk.

In May 2018, we introduced the CME CF Ether-Dollar Reference Rate (ETHUSD_RR) and CME CF Ether Real-Time Index (ETHUSD_RTI) to allow for ready access to real-time ether prices in US dollars.

What is the relationship between Ether futures and the underlying spot market?

CME Ether futures are based on the CME CF Ether-Dollar Reference Rate, ETHUSD_RR, which aggregates ether trading activity across major spot exchanges between 3:00 p.m. and 4:00 p.m. London time.

On which exchange are Ether futures listed?

Ether futures are listed and cleared on CME, a US-registered designated contract market (DCM) and derivatives clearing organization (DCO).

What regulation applies to the trading of Ether futures?

The trading and clearing of Ether futures is regulated by the Commodity Futures Trading Commission (CFTC), the regulatory body with exclusive jurisdiction over US Ether futures markets.

What accounting and other regulatory treatment is afforded to Ether futures in my local jurisdiction?

As with any other derivatives product, the accounting treatment of positions in Ether futures, and the general local regulatory treatment of trading in Ether derivatives, may differ by country and between competent jurisdictions. Market participants are responsible for complying with all applicable US and local requirements. Market participants, particularly those with no experience in trading Ether derivatives, should seek professional counsel as necessary and appropriate to their circumstances.

Which platforms support Ether futures trading?

The platforms include a central limit order book via the CME Globex platform and ex-pit trade submission for clearing via CME ClearPort and CME Direct.

Do I need a digital wallet to trade Ether futures?

No. You do not need a digital wallet, because Ether futures at CME Group are financially settled and therefore do not involve the exchange of ether.

In order to trade futures, you must open an account with a registered futures broker who will maintain your account and guarantee your trades. In the futures business, brokerage firms are known as either futures commission merchants (FCMs) or introducing broker (IBs). Learn more here.

How is the Ether futures daily settlement price determined?

CME Group staff determines the daily settlements for Ether futures based on trading activity on CME Globex between 14:59:00 and 15:00:00 Central Time (CT), the settlement period.

Tier 1: Each contract month settles to its volume-weighted average price (VWAP) of all trades that occur between 14:59:00 and 15:00:00 CT, the settlement period, rounded to the nearest tradable tick. If the VWAP is exactly in the middle of two tradable ticks, then the settlement will be the tradable price that is closer to the contract’s prior day settlement price.

Tier 2: If no trades occur on CME Globex between 14:59:00 and 15:00:00 CT, the settlement period, then the last trade (or the contract’s settlement price from the previous day in the absence of a last trade price) is used to determine whether to settle to the bid or the ask during this period.

  1. If the last trade price is outside of the bid/ask spread, then the contract month settles to the nearest bid or ask price.
  2. If the last trade price is within the bid/ask spread, or if a bid/ask spread is not available, then the contract month settles to the last trade price.

Tier 3: In the absence of any trade activity or bid/ask in a given contract month during the current trading day, the daily settlement price will be determined by applying the net change from the preceding contract month to the given contract month’s prior daily settlement price.

Are Ether futures subject to price limits?

Yes, Ether futures are subject to price limits on a dynamic basis. At the commencement of each trading day, Ether futures, are assigned a price limit variant which equals a percentage of the prior day’s exchange-determined settlement price, or a price deemed appropriate by the GCC. During the trading day, the dynamic variant is applied in rolling 60-minute look-back periods to establish dynamic lower and upper price fluctuation limits as follows:

  • The dynamic variant is subtracted from the highest trade and/or bid price during a look-back period to establish the lower price fluctuation limit
  • The dynamic variant is added to the lowest trade and/or offer price during a look-back period to establish the upper price fluctuation limit

How is the Ether futures final settlement price determined?

The final settlement value is based on the CME CF Ether-Dollar Reference Rate at 4:00 p.m. London time on the expiration day of the futures contract.

What is the maximum order size for Ether futures on CME Globex?

The maximum order size is 100 contracts.

Are options on Ether futures available for trading?

CME will not initially list options but will reassess introducing options once the futures market develops and as customer demand evolves.

CME CF Ether-Dollar Reference Rate (ETHUSD_RR)

What is the CME CF Ether-Dollar Reference Rate (ETHUSD_RR)?

Launched in 2018, the CME CF Ether-Dollar Reference Rate (ETHUSD_RR) is a daily reference rate of the US dollar price of one ether as of 4:00 p.m. London time.

Designed by CME Group and CF Benchmarks around the IOSCO Principles for Financial Benchmarks, ETHUSD_RR aggregates the trade flow of major ether spot exchanges during a specific calculation window into a once-a-day reference rate of the US dollar price of ether. Calculation rules are geared toward maximum transparency and real-time replicability in underlying spot markets.

When is the ETHUSD_RR published?

The ETHUSD_RR is published between 4:00 p.m. and 4:30 p.m. London time every day, including weekends and holidays.

Who is CF Benchmarks?

CF Benchmarks is the benchmark administrator for the ETHUSD_RR, authorized and regulated by the UK Financial Conduct Authority as a registered Benchmark Administrator. CF Benchmarks is not affiliated with CME Group.

What is the CME CF Ether-Dollar Real-Time Index (ETHUSD_RTI)?

The CME CF Ether-Dollar Real-Time Index (ETHUSD_RTI) aggregates global demand to buy and sell ether into a consolidated order book that reflects the fair, instantaneous US dollar price of ether. It is geared toward low latency and timeliness and is based on forward-looking input data.

How often is the CME CF Ether-Dollar Real-Time Index (ETHUSD_RTI) published?

The ETHUSD_RTI will be published approximately once per second of every day, including weekends and holidays.

What methodology is being used in calculating the rates?

Calendar Spreads

What calendar spreads does CME Group list?

CME Group will list all possible combinations of the listed months.

What are the ticker symbol conventions for calendar spread trading?

Buying the spread is equivalent to buying the deferred contract month. For example:

ETHF1 – ETHH1 is the Jan21/Mar21 spread. Buying this spread means buying the Mar21 contract and selling the Jan21 contract.

If you are long the Jan21 contract, buying the Jan/Mar spread will extend your expiration into March.

View contract month codes

What does the spread price signify? How are separate contract priced when I do a spread trade?

The price of the spread trade is the price of the deferred expiration less the price of the nearby expiration.  After the spread trade is done, the price of the two contracts will be determined using the following convention:

The nearby contract is priced at its daily settlement price on the previous day. The deferred contract is priced is nearby contract’s assigned price plus the spread price.

For example:

  • Bought ETHF1-ETHH1 @-100
  • Assuming ETHF1 prior settle = 455
  • Price of the two legs: sold ETHF1 @ 455, bought ETHH1 @ 455 + (-100) = 355.
