IN SHORT: Robasta premiums offered

Vietnamese robusta were offered at premiums to London futures for the first time since early February after farmers held back their stocks, while roasters sought to buy Indonesian beans at a bargain, dealers said on Friday.
Vietnam's grade 2, 5 percent black and broken robustas were quoted at premiums of $10 to $20 to London's May contract, versus discounts of up to $30 last week. The beans were last offered at premiums in early February.
