Bigger robusta bean harvests in Brasil and Vietnam are driving down coffee futures.
Robusta traded in London has fallen 26% since March... and will drop another 5% by Dec. 31.
Estimates are that Brasil's output will rise 14% to 14.5 million bags.
Though stockpiles are rising and futures slumping, consumers may not see price relief for 6 months.
Roasters and retailers must first deplete inventories purchased at higher costs.
