Strait of Hormuz Traffic Increases Amid Ongoing Tensions Between US and Iran

Ship traffic has picked up in the Strait of Hormuz since Iran and the US signed an interim deal to end a war that constricted global oil supplies and fueled inflation, but questions surrounding control of the vital waterway and whether vessels will be charged tolls to cross it could interfere with negotiations to forge a lasting peace. Tehran and Washington clashed over the Strait of Hormuz again this past weekend. Citing Israel's latest attacks on Lebanon, Iran declared that it reclosed the strait . The U.S. was quick to contest that. Maritime tracking data showed that dozens of ships passed through on Saturday and Sunday, though far fewer than the daily average before the war. President Donald Trump suggested the U.S. might impose its own tolls on strait crossings if a final deal with Iran was not reached during the countries' 60-day negotiating period. Passage was free before the war, but Iran last month established a new governmental authority to collect money from ships and has said it still expects vessels to register with the Persian Gulf Strait Authority. No one country owns the Strait of Hormuz, which borders both Iran and Oman. Last week's memorandum of understanding allowed Iran to manage the strait for now while holding discussions with Oman and six other Gulf states "to define the future administration and maritime services" of the waterway. Iran agreed not to charge transiting vessels tolls for 60 days. Legal experts and maritime associations have repeatedly stressed that a toll regime would upend decades of international trade precedent involving the world's waters. If the U.S. and Iran cement a final deal, analysts say it could take months for the flow of oil, natural gas, fertilizer and other commodities to return to prewar levels. Here's a closer look at the status of the Strait of Hormuz: Data and analytics company Kpler said its tracking confirmed 71 ships traveled through the strait between Friday and Sunday, with a peak of 35 crossings Saturday. In contrast, about 100 to 130 vessels a day made the journey before the U.S. and Israel launched strikes on Iran in late February, and Tehran responded with its own attacks and effective closure of the waterway. As part of the provisional Iran-U.S. framework, Iran said it would conduct demining work within 30 days and remove "technical and military obstacles" to shipping. Iran's lead negotiator and parliament speaker, Mohammad Bagher Qalibaf, told Iranian state media Monday that his country would manage the strait in accordance with international maritime law. The main central route of the Strait of Hormuz is still mined and remains closed. Ships have been using the smaller northern route, which goes through Iranian waters, and the southern route, which goes through Omani waters. But "caution is still clear" in the many vessels either sticking to Iran's prescribed route or trying to conceal their positions and identities by keeping their transponders off, Kpler said.
