The weekend figures, corroborated by Kpler tracking, highlight a cooling in maritime movement as geopolitical friction intensifies. While 13 vessels moved through the strait on Saturday, the drop to four the following day underscores the caution gripping the shipping industry. Total transit volume for the week ending August 21 saw 103 arrivals and 89 departures, yet the underlying trend remains one of sustained contraction.

This atmospheric shift follows an aggressive declaration from U.S. Treasury Secretary Bessent, who warned of an "economic D-Day" aimed at dismantling Iran’s financial and nuclear ambitions. Tehran responded with a vow to choke off regional oil exports entirely. Mohsen Rezaei, secretary of Iran's Supreme National Security Council, stated that if economic pressure persists, not a single drop of oil will exit the Persian Gulf. Despite these warnings, oil prices softened at the week's opening as traders weigh the potential for supply disruptions against the lack of specific details regarding the announced U.S. offensive.
