Farmers in the Central Highlands, Vietnam’s largest coffee growing area, sold coffee COFVN-DAK at 30,300-31,000 dong ($1.30-$1.33) per kg on Thursday, compared with 30,500-31,400 dong last week.

"Local coffee growers have frozen their sales on falling prices," a Ho Chi Minh City-based trader said. "I don’t see any factors that help push up prices in the near term."

Traders in Vietnam offered 5 percent black and broken grade 2 robusta COFVN-G25-SAI at a $45 per tonne discount to the July contract, flat from last week.

The government’s General Statistics Office said on Monday Vietnam’s coffee exports in April will likely fall 14.4 percent from a year earlier to 140,000 tonnes.

"The decline in shipments from Vietnam in April doesn’t seem to have any impact on global prices as supplies from Brazil is still strong," the trader said.

Meanwhile, in Indonesia, premiums for the grade 4 defect 80 robusta COFID-G4-USD rose to $170 to the July contract on Thursday from $130 a week ago, according to a trader based in Lampung.

"Traders widened the premiums to compensate for the drop in benchmark prices," the trader said, adding that demand has also been strong.

July robusta coffee settled down $31, or 2.2%, at $1,376 per tonne on Wednesday, after dropping to 1,365, the lowest since February 2016.

Indonesia’s local government data released on Thursday showed exports from Lampung in April fell 49 percent from a year earlier to 4,326.3 tonnes.
