Commenting on the "shrinkflation" phenomenon, SMU Assistant Professor of Finance (Education) Aurobindo Ghosh said that "shrinkflation" typically occurs after significant inflation in both finished goods and raw materials. He said that Singapore, which relies heavily on imports for most food and consumer goods, is particularly vulnerable to this phenomenon. Asst Prof Ghosh also noted that milk powder, instant coffee and tea, ice cream, laundry detergent, and diapers are all everyday items purchased in bulk and pre-packaged. Therefore, they are more prone to "shrinkflation" compared to goods like rice, fruits, and vegetables, which are purchased by weight and priced per unit.
