September arabica coffee (KCU26) closed up +18.30 (+5.30%) on Tuesday, and September ICE robusta coffee (RMU26) closed up +85 (+2.32%).
Coffee prices added to Monday’s sharp gains on Tuesday, with arabica surging to a 6.5-month high. The slow pace of Brazil's coffee harvest is limiting coffee supplies and pushing prices sharply higher. Safras & Mercado reported last Friday that the Brazil 2026/27 coffee harvest was 90% completed as of August 12, behind 97% last year and the 5-year average of 94%. Brazil's arabica coffee harvest was 86% complete, behind last year's 95%. Meanwhile, the harvest among members of Cooxupe co-op was 74.6% complete as of August 7, behind last year's comparable figure of 80.4%, according to a report released last Wednesday.
