Trump plans to block the Strait of Hormuz to pressure Iran, experts warn that enforcement will be difficult and may trigger retaliatory escalation

Mars Finance News, April 13 — U.S. President Donald Trump proposed a maritime blockade of the Strait of Hormuz to pressure Iran to make concessions in negotiations. The U.S. Central Command stated that the blockade would target ships entering and leaving Iranian ports and has set a start time.
Several security and military experts pointed out that a maritime blockade essentially constitutes acts of war, requiring a large naval force to maintain over a long period, and lacking a clear end path. Its execution is highly challenging and its sustainability is questionable.
Dana Stroul said that this operation cannot be completed alone and may be difficult to sustain in the medium to long term.
Analysis suggests that this move could trigger reciprocal retaliation from Iran. Former U.S. Navy Combatant Commander Gary Roughead warned that Iran might attack Gulf shipping or U.S. military infrastructure in the Middle East, increasing the risk of further regional conflict escalation.
Additionally, there are complex practical issues in executing the blockade, including whether to intercept or even sink third-country oil tankers, and how to handle energy transportation involving U.S. allies.
Mark Worner also questioned the actual effectiveness of this strategy, noting that Iran could still counter with mines or asymmetric means.
The Strait of Hormuz accounts for about 20% of global oil transportation, and the geopolitical risk has already driven oil prices sharply higher.
The market generally believes that if tensions persist, it will further intensify inflationary pressures and disrupt global energy and financial markets.
