Iran's closure of the Strait of Hormuz highlights Europe's dependency on narrow sea passages. Disruptions at Hormuz, Suez, Bab el-Mandeb, Malacca, Dover, Gibraltar, and Bosphorus lead to energy, fertilizer, and food price spikes.

Europe's economy relies heavily on these choke points for trade. Alternatives like the Cape of Good Hope and Arctic routes come with logistical and geopolitical challenges. The EU aims to bolster port security and diversify trade routes but acknowledges ongoing vulnerabilities.

Without viable alternatives, Europe must focus on reducing reliance on fossil fuels and diversifying supply chains.
