The price for some intra-Asia container shipping services, such as the container shipping fee for China-to-Singapore freight, raised up to five-year high in mid-November 2020. Some Singapore consumers believed that annual major promotion of leading ecommerce sites in China and Singapore, especially the double-11 shopping festival, caused the rapid increase of China-to-Singapore container shipping cost. However, others speculated that there might be some supply-side changes causing the spike in sea shipping rate.
