* Oil prices plummeted more than 7% in response to the news on Thursday, encouraging Brazilian cane mills to produce sugar rather than biofuel ethanol.
* A softer Brazilian real, which hit a near one-month low against the dollar on Thursday, also weighed - encouraging Brazilian traders to sell dollar-denominated commodities like sugar.
* Added to this, sugar traders are still digesting signs of plentiful near-term supplies, such as massive recent deliveries of sugar against ICE futures contracts and large global stockpiles.

* The expectation that funds could rebuild their net short position is also weighing.
* Fund short-covering had helped to fuel a rebound in prices during the past couple of months, but the run-up has stalled and the speculative net short has begun to rise again.
