NEW YORK, July 21 (Reuters) - Robusta coffee futures on ICE fell nearly 5% on Monday to hit a 16-month low with newly harvested beans from Brazil and Indonesia ensuring that supplies remain ample while cocoa regained some ground after recent weakness.
COFFEE
* Robusta coffee LRCc2 settled down $161, or 4.8%, at $3,187 a metric ton.
* Brazilian robusta growers are offering their recently-harvested lots at significant discounts compared to robusta from Vietnam, Archer Consulting said in a note.
* Dealers noted the market's main focus remained on whether the U.S. would go ahead with the planned 50% tariff on imports on Brazilian coffee from August 1.
* Brazil's finance minister said on Monday his country would not give up negotiating with the U.S. but acknowledged that a trade deal may fail to be reached by August 1.
* About a third of U.S. coffee comes from Brazil and the tariffs, if they transpire, would all but halt the flow of Brazilian beans to the U.S., the world's top coffee drinker.
* Arabica coffee KCc2 lost 3.8% to $2.9195 per lb.
COCOA
* London cocoa LCCc2 settled up 145 pounds, or 2.9%, to 5,109 pounds per ton in a modest rebound after falling by around 4% last week on bearish second quarter grind data.
* Dealers said second quarter grind from Asia, Europe and North America showed an overall decline of around 10%, reinforcing concerns that the rise in prices last year has curbed demand.
* New York cocoa CCc1 rose 4.6% to $8,156 a ton.
* Many cocoa trees in Ivory Coast's key growing regions are flowering, with some showing small pods in a promising sign for the October to March main crop, farmers said on Monday, adding though that more sunshine is needed to boost growth.
SUGAR
* Raw sugar SBc1 settled down 0.45 cent, or 2.7%, at 16.37 cents per lb.
* Dealers said the failure of the market to stay above the 17-cent level reached on Friday - which could have sent speculators to cover more of their shorts - led to a downward consolidation.
* They noted early indications of a potential global surplus in the 2025/26 season with a strong monsoon boosting production in India and Thailand.
* White sugar LSUc1 fell 2.8% at $474.20 a ton.
