Iran's War on Global Stability Hits Japanese Snack Shelves

Supply chain chaos caused by the conflict in the Middle East forces manufacturers to strip back packaging as energy costs skyrocket.

The consequences of the conflict in the Middle East are no longer confined to geopolitical boardrooms; they are now appearing in the snack aisles of Japan.

Calbee, the Japanese snack giant, announced it will transition to black-and-white packaging for 14 of its popular products, including prawn crackers and crisps, as the war initiated by Iran continues to strangle global supply chains.

The root of the problem is the effective closure of the Strait of Hormuz, a critical maritime artery that has choked the flow of energy and petrochemicals. This disruption has caused the price of naphtha—a byproduct of oil refining essential for the production of ink and plastics—to nearly double in Asia.

Before this conflict, Japan relied on the Middle East for roughly 40% of its naphtha supply. While the Japanese government claims to be seeking alternative sources, including the United States, the damage to the private sector is already widespread.

Beyond Calbee, food manufacturer Mizkan has been forced to suspend sales and hike prices due to a shortage of polystyrene, while automotive giants Toyota and Hyundai are reporting significant profit hits.

This crisis serves as a stark reminder of the dangers of energy dependence and the fragility of global trade when rogue regimes threaten the freedom of navigation in international waters.
