Coffee chains such as Starbucks, Tim Hortons, and Luckin Coffee have increased the prices of some drinks in China due to rising coffee bean costs and operational expenses. Starbucks raised prices by 1 to 2 yuan per drink, while Luckin Coffee increased prices by about 3 yuan for some drinks in December. The price of arabica beans, widely used by these chains, has reached a 10-year high of $2.56 a pound due to low inventory levels and production issues in top producers like Brazil and Colombia. Civil conflicts in Ethiopia and unfavorable weather conditions in Colombia have further increased the demand for coffee beans, leading to the price hikes.
