NEW DELHI, May 5 (Reuters) - Asia's naphtha refining profit margin gained on Monday after crude oil benchmarks declined on oil producers' group OPEC+ decision to accelerate output hikes.

The crack climbed to $104.73 per metric ton over Brent crude, the highest level since March 28. Price for second-half June naphtha plunged by $10 to $554.50 per ton.

"The sudden crash in naphtha price helped to widen petrochemical margins and improve demand for the feedstock, but outlook is still clouded by the on-going trade war, which will weigh down on the upcoming U.S. consumer summer demand for Chinese goods," LSEG Research said in a note.

The gasoline crack traded strongly at around $11 per barrel over Brent crude amid firm Indian demand.

In, Japan, ENEOS refinery was heard seeking gasoline cargo after some technical glitch at one of its units.
