Platts Market on Close
What it is & why it matters

A structured and transparent methodology to determine commodity price assessments, operating on the principle that price is a function of time.

The MOC Process

The process involves market participants submitting firm bids, firm offers, and confirmed transactions to Platts editors. This information is published in real time via the Platts Editorial Window (eWindow).

Real-Time Data Visibility: The Platts eWindow

Platts eWindow interface

The eWindow provides the real-time flow of market information.

Process 1

Physical MOC (LNG)

Focused on transactions for physical delivery. Prices can be fixed outright or floating against benchmarks like JKM.

16:00
Singapore Time

Submission cut-off for Physical MOC (Asia).

Can companies trade published bids/offers?

YES

Trades are bilateral. A company can "click trade" on eWindow or inform editors. Parties negotiate directly, finalize, and report back.

Performance: Platts expects all reported LNG MOC trades to be physically performed. Reasonable substitutions allowed.

When MOC Orders are Submitted and Published
