"I think it is a technical move. We went through yesterday's highs and there were a cluster of moving averages which got broken on the upside which added impetus to the move," one dealer said.

COFFEE
September arabica coffee settled up 1.15 cent, or 0.9 percent, at $1.3595 per lb, right around the 100-day moving average.
Dealers said the advance in prices was fueled by the recent strength of top grower Brazil's currency, which makes global prices less attractive in local currency terms to growers.
