A price cap protects consumers from being overcharged, but it also cuts what a supplier earns per unit — so its effect depends entirely on whether supply can grow while the cap is on. The sanitiser case in the box is worth reading closely, because it shows both halves.
| Consumers | Suppliers | |
|---|---|---|
| Immediate effect | Pay no more than ₹100 for a 200 ml bottle; protected from hoarders and black-marketeers | Earn less per bottle than the shortage price they could have charged |
| Risk if supply cannot grow | A shortage: at the capped price more is wanted than is offered, so there are queues, rationing by the shopkeeper, or an illegal market at a higher price | Weaker incentive to produce; some may divert stock to the black market instead |
| What actually happened in 2020 | Sanitisers “soon became widely available at fair prices” | “Many companies started production” — new firms entered and total supply rose sharply |
