Across all cities, a clear pattern emerges from the charts — if arrivals dip, prices surge. However, how is this price rise being managed, and who benefits from this? Charts 5A, 5B and 5C depict the difference between the wholesale price and retail price in all the months between Jan. 2017 and Nov. 2021. As can be observed, the price difference is peaking again in November 2021.

The graphs show that this is a routine practice almost every year-end when supplies drop and demand peaks.
