Trade in Asian coffee markets in Vietnam was sluggish amid post-holiday sentiment, while stocks in Indonesia remained low, traders said on Thursday.

Farmers in the Central Highlands, Vietnam’s largest coffee-growing area, sold coffee at 31,000-31,500 dong ($1.34-$1.36) per kg, compared with 32,300-32,500 dong range in the week before the Lunar New Year.

“Trading is yet to return normal after the long holiday,” said a trader based in the coffee belt. “Some of the buyers are hoarding the beans on expectations of higher prices.”

Meanwhile, farmers were not willing to sell beans at this price, which traders said was not enough to cover the production cost, while some growers have already sold passion fruits or durians, planted alongside coffee trees, to cover their needs.

Coffee exports from Vietnam, the world’s biggest producer of the robusta bean, dived 30.6% from a year earlier to 140,000 tonnes in January, official data showed on Wednesday.

May robusta coffee settled down $20, or 1.5%, at $1,317 per tonne on Wednesday.

Traders in Vietnam offered 5% black and broken grade 2 robusta at $80-$90 premium per tonne to the May contract on Thursday, compared with the $70-$80 premium to the March contract two weeks ago.

Meanwhile, Indonesia’s grade 4 defect 80 robusta beans were offered at premiums of $240-$250 to the March contract this week, a trader in Sumatra’s Lampung province said. In comparison, beans were offered with $220-$250 premiums two weeks ago.

“Trade is still quiet since supply is very limited,” the trader said.
