Nov. 2 (Bloomberg) -- Coffee rose the most in seven weeks in New York as a drop in the dollar and a holiday in Brazil, the world’s largest producer, eased selling pressure on the market.

The dollar fell as much as 0.8 percent against the euro. Because of a holiday in Brazil, many sellers didn’t work today, said Rodrigo Costa, a Newedge USA LLC institutional sales vice president in New York.

Coffee climbed “based on the dollar” and on the holiday in a key producer such as Brazil, Costa said.

Arabica-coffee futures for December delivery rose 6.85 cents, or 5.1 percent, to $1.4235 a pound on ICE Futures U.S. in New York, the biggest gain since Sept. 14. The price fell 1.2 percent last week.

“We’re having just a correction from last week, when everything went down dramatically, coffee as well,” Costa said.

Coffee has gained 27 percent this year amid tight supplies from Central America and Colombia, the world’s largest producer after Brazil and Vietnam.
