Platts proposes to change increments guideline for Asia LNG derivatives MOC
Platts, part of S&P Global Commodity Insights, is proposing to change the timing and increments guidelines for its Asia Market on Close derivatives assessment process, effective Nov. 17.
For the Asia LNG derivatives MOC, Platts proposes to allow for counterparties to improve a 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.
The maximum time allowed for participants to repeat a bid or offer for Asia LNG derivatives MOC following a trade would remain at 20 seconds.
The following table summarizes the proposed changes on eWindow:
| Product | Environment | Repeatability | Final State | Repeat/Change of an order which triggers extension of the window (extension trigger period) | Period of testing the repeatability of an order repeated/changed near the close (Extension state) | Current Max Increment/Frequency | Proposed Max Increment/Frequency |
| Asia LNG Derivatives (JKM, WIM, and their spread) | eWindow | Within 20 seconds | N/A | 16:29:40:000 to 16:30:00:000 | 16:30:01:000 to 16:31:00:999 | 10 c per 20 s | 5 c per 20 s |
Platts has established clearly defined timing and increment guidelines that apply when publishing bids and offers in the MOC process, in order to ensure an orderly and transparent price assessment process.
Guidelines for the publication of bids and offers in the MOC process are available in the Platts LNG Timing and Increment Guide, available here: https://www.spglobal.com/commodityinsights/plattscontent/_assets/_files/en/our-methodology/methodology-specifications/lngtiming.pdf .
