Amendments to NYMEX/COMEX Rule 589 (Special Price Fluctuation Limits) and NYMEX Rulebook Chapters for Certain NYMEX Energy Futures and Options Contracts

(This SER supersedes SER 7346 dated May 19, 2015 to reflect revised language in NYMEX/COMEX Rule 589.)

Effective Sunday, May 31, 2015 for trade date Monday, June 1, 2015, and pending all relevant CFTC regulatory review periods, the New York Mercantile Exchange, Inc. (“NYMEX”) and Commodity Exchange, Inc. (“COMEX”) (collectively, the “Exchanges”) will amend NYMEX/COMEX Rule 589 (Special Price Fluctuation Limits) to reflect the change from an unlimited number of price expansions per day to four price limit expansions per day. Following the fourth price limit level, there will be no further price limits in effect. In addition, for energy contracts, there shall be no special price fluctuation limits on the expiration day for an expiring energy contract.

Further, NYMEX will amend the special price fluctuation limits for 5 energy futures contracts.  These rulebook chapters will be amended to reflect changes to special price fluctuation limits in NYMEX/COMEX Rule 589.  In an effort to harmonize the price limit-related rules across all four of CME Group’s exchanges to the greatest extent possible, NYMEX is extracting the relevant rules from the energy product chapters to NYMEX/COMEX Rule 589.

The 5 energy futures contracts are as follows:
