A widening dispute over how much oil is moving through the Strait of Hormuz is creating a murky picture of one of the world's most important energy corridors, particularly as the White House and independent shipping trackers offer dramatically different assessments of traffic through the waterway.
Ship-tracking service Kpler said traffic through the Strait of Hormuz "declined sharply" on Monday, with only five vessels crossing. That same day, the United States and Iran exchanged fire for the first time in a month, renewing concerns about the security of energy shipments from the Persian Gulf.
