The clearing house plans on making a change to all of the current Business Function Commodity Code (BFCC)
names that we have for Comex and Nymex products. Currently all Comex products are preceded with “CMX-“
and Nymex products preceded with “NYM-“. This system worked well as both exchanges only used 2 letter
codes to define products. Now with the expansion of Nymex product listings we cannot continue this trend.
Due to a 6 digit limitation to BFCC names we will need to make a change. Now all of the Comex products
will be started with “CX-“ and Nymex products will proceed with “NY-“.
These changes will be made for RTH June 25th.
For testing of these changes they will be in the testDev folder on the FTP site: ftp://ftp.cme.com/pub/span/data/cme/testDev/
If there are any questions about the change please contact the risk department at 312-648-3888.
