The CME issued a notice on the position limit, position limit aggregation, and large trader reporting rules for two new half month Platts based contracts on Japan/Korea LNG. There are couple points in the order that provide the opportunity to refresh position limit rules on the CME.
First, the large trader reporting limit (the level at which your positions will be reported by name to the CFTC) is only 25 contracts. It is likely anyone trading this contract will be subject to the broker reporting rules.
Second, these two contracts aggregate for position limit purposes up into the the full month JKM contract. Therefore, JKM (full month), JKF (front half month), and JKB (back half month) will all aggregate up into a single position for spot and all month accountability position limits.
It is important to remember that the aggregation rules for position limits as well as declining balance contract analysis are important component of your position limit analysis.
We would like this to be helpful to both US and non-US based firms trading in this and other CME products.
