Start from a preset

Open one, then change anything in it.

• Strait of Hormuz closed for 3 monthsNo ship enters or leaves the Gulf, so crude, LNG, fertiliser and container trade must find another way or stop.
• Red Sea crisisContainer lines and car carriers avoid Bab el-Mandeb and the Red Sea for a year, as through 2024. Tankers and bulkers keep going.
• Venezuela blockadeA naval blockade stops every ship to and from Venezuela's ports for 3 months. Air and land routes stay open.
• Czech airspace closedCzech airspace is shut to all flights for 3 months, so Prague's air cargo and the flights over the country reroute or stop.
• Ukrainian rail corridor cutThe rail lines from Ukraine to Poland, Slovakia, Hungary, Romania and Moldova are cut for 3 months. Ports and roads stay open.
• Canada blockadeCanada's trade stops by sea, air, rail, road and pipeline, in both directions, for one month.
• Panama Canal drought restrictionsLow water at Gatún Lake holds the canal to 65% of its usual traffic for 6 months, as in 2023–24.
• Strait of Malacca closedNo ship passes the Strait of Malacca for 3 months, so trade between the Indian Ocean and East Asia goes round by Sunda, Lombok or further.
• Taiwan Strait closedShipping avoids the Taiwan Strait for 3 months and sails east of Taiwan instead. Taiwan's ports stay open.
