Iran's Islamic Revolutionary Guard Corps reported that 20 merchant vessels transited the Strait of Hormuz within a 24-hour period [1].
This movement occurs amid heightened regional tensions and disputes over sanctions. The IRGC's assertion of control over the narrow waterway between Iran and Oman serves as a signal of its ability to regulate critical global shipping lanes.
According to a spokesperson for the IRGC, the number of ships passing through the strait reached 20 in a single day [1]. This report follows previous statements regarding the necessity of Iranian oversight for maritime traffic. An Iranian official and IRGC representative said that ships crossing Hormuz need IRGC approval, and that the organization has reopened the waterway under its supervision [2].
The IRGC has specifically noted the passage of vessels from various nations. An IRGC official said that Chinese vessels were allowed to transit safely through the strait overnight [3]. These movements are presented by Tehran as evidence that the waterway remains open for commercial use provided that IRGC protocols are followed.
The reported traffic follows a period of volatility in the region. On April 17, 2026, reports indicated that the IRGC was actively managing the passage of ships as part of a broader strategic posture [2]. The IRGC continues to maintain that its supervision is necessary to ensure security in the corridor.
While some reports suggested a higher number of transits, the IRGC's specific count of 20 ships remains the verified figure from the primary reporting channels [1]. The organization maintains that this level of activity demonstrates a stable flow of commerce under its authority.
“"According to the IRGC, 20 ships have passed through the Strait of Hormuz in the last 24 hours."”
The IRGC's public accounting of ship transits is a strategic communication intended to project authority over one of the world's most critical oil chokepoints. By emphasizing that the strait is 'open' but requires 'approval,' Iran reinforces its role as the regional gatekeeper, using maritime access as a lever in its ongoing diplomatic and economic disputes with the U.S. and other international powers.
