CATALAYER PUBLIC MARKET ANALYSIS

Summary

Vice President JD Vance told reporters that tankers carrying more than 12 million barrels had crossed the Strait of Hormuz overnight, the first independent confirmation of ships moving under the U.S.-Iran interim agreement. WTI futures fell about 2% to $75.27 and Brent was around $78.11 on the day.

Market Impact

The confirmation of physical ship transits through Hormuz validated the market's repricing of supply-risk premia, with the rapid price decline showing how tightly crude had priced in closure risk. Before the conflict the strait handled roughly 14 million barrels of crude and 6 million barrels of refined products daily. This analysis is informational and avoids any directional trading claims.
