India's Diet Coke price jumps as Iran war disrupts aluminum can supply

The U.S.-Israeli war against Iran has shut the Strait of Hormuz, choking the flow of aluminum cans that Coca‑Cola uses for its Diet Coke cans in India. With the usual 300 ml cans scarce, the company turned to larger, more expensive cans sourced from Southeast Asia.

Coca‑Cola raised the price of Diet Coke by more than 10 percent, moving the standard 300 ml can from 40 rupees to a 330 ml can at 50 rupees—a 13.6 percent increase per millilitre. Some bottlers have briefly offered 200 ml glass bottles, which are even costlier. The shortage sparked unusual “Diet Coke parties” in the market, underscoring how a Middle‑East conflict can ripple into everyday consumer prices in one of the world’s largest soft‑drink markets.
