LONDON: Arabica coffee futures on ICE rose on Friday, heading back towards a four-year high hit a day earlier amid tightening supplies in top producer Brazil, improved demand and a stronger Brazilian real.

Arabica supplies are tightening as Brazil enters an off-year in its biennial crop cycle. There are also signs demand is recovering after results from coffee makers such as Starbucks , Keurig Dr Pepper and Tata Coffee.
Colombia's, the world's second-largest arabica producer, has discovered nine new, more aggressive variants of the fungus that causes coffee rust, a disease that can cause losses of between 30% and 80% in susceptible plant varieties.

May raw sugar, which expires on Friday, fell 1.5%, to 16.83 cents per lb. The contract hit a two-month peak of 17.98 on Tuesday.
Traders said that while nervousness about the cane crop on top producer Brazil persists, output in key regions of India and Thailand is improving and the global market should be more or less balanced this year.
Brazil's center-south cane crush in the new season will be the lowest since 2012, according to commodities trader and supply chain services firm Czarnikow, as below-average rains hurt cane development.
Dealers do not expect a large delivery against the May raws expiry, citing supply tightness in Brazil as one possible reason.
