Platts to change increments and timing guidelines for Asia LNG derivatives MOC from May 18
Platts, part of S&P Global Energy, is changing the timing and increments guidelines for the Asia Market on Close derivatives assessment process, effective May 18.
Platts first proposed the changes on Feb. 27, in a subscriber note available here , with the extended feedback period ending April 16.
Following an analysis of MOC data and market feedback, Platts will adjust the timing cut-off for the submission and subsequent publication of bids and offers to 16.15.00.000 SGT, from the current 16:10:00.000 SGT.
Platts will also allow counterparties to improve a maximum of 5 cents/MMBtu per 10 seconds for bids and offers submitted through the Platts Editorial Window, or eWindow, communication tool, and 5 cents/MMBtu per 20 seconds for bids and offers submitted through a Platts editor manually.
This compares with the current maximum of 5 cents/MMBtu per 20 seconds for bids and offers submitted through the Platts Editorial Window, or eWindow, communication tool, and 5 cents/MMBtu per 30 seconds for bids and offers submitted through a Platts editor manually.
In line with the above amendments, the maximum time allowed for participants to repeat a bid or offer following a trade in the Asia LNG derivatives MOC is proposed to be 10 seconds.
In this regard, and as an interim measure, Platts had adjusted incrementability guidelines on March 6, to allow bids and offers for Asia LNG derivatives to improve by up to 10 cents/MMBtu every 10 seconds, until further notice. The temporary change was implemented in response to heightened market volatility following vessel transit disruptions via the Strait of Hormuz.
The lifting of this interim measure will coincide with the May 18 implementation of these new incrementability guidelines.
The following table summarizes the changes:
