Platts proposes MOC timing, increments guidelines for Brazil Refined Products assessments

Platts, part of S&P Global Energy, proposes introducing timing and increment guidelines for its Brazilian Domestic Refined Products Market On Close assessment process, effective July 1, 2026, to align with existing MOC practices for Platts Americas Refined Oil Products assessments.

The timing and increment guidelines will apply to all firm bids or offers reported directly to Platts for publication in Platts Brazil domestic gasoline and diesel MOCs.

Timing and increment guidelines are a key component of Platts assessment methodology, essential to an orderly and transparent publishing process.

When determining a final market assessment, Platts gives the highest priority to fully verifiable and transparent market information from entities that have been reviewed for participation in the MOC.

MOC timing, increments

To ensure sufficient time for all market information to be tested, participants should submit any firm bids and offers with complete information to Platts price reporters by phone, instant messenger, or email before 3:30 pm Brasilia time.

Counterparties may improve the price of their published bids or offers every 5 minutes, by a minimum increment of Real 5/cubic meter, and a maximum increment of Real 10/cubic meter.

No price change will be allowed in the final five minutes of the MOC, which concludes at 4:30 pm Brasilia time.

Participants may withdraw their bids or offers at any time during the MOC by communicating that to the Platts editorial team, so long as interest to trade against the previously published bid or offer has not already been received by Platts.

Participants must clearly communicate their expression of interest to trade a published bid or offer to Platts reporters, and counterparties are expected to promptly report confirmation of consummated trades back to Platts.

Participants who have submitted a firm bid or offer to Platts for publishing in the MOC are expected to remain contactable at all times prior to the close at 4:30 pm Brasilia time, unless the submitted firm bid or offer has been withdrawn.

Bids or offers that have traded in the MOC may be repeated at the same or a less competitive price; participants will have two minutes to do so after an initial expression of interest to trade is published.

All previously submitted firm bids or offers that have not been traded will be withdrawn at the 4:30 Brasilia time close.

Platts may adjust its timing and increment guidelines in the event of market volatility or a disruptive event.

The timing guidelines that will apply are listed in the table below:
