US President Donald Trump has threatened to impose a full blockade on the Strait of Hormuz, even as Iran already restricts access to the crucial waterway, in a move aimed at increasing pressure on Tehran during ongoing conflict.
While Iran has not completely shut the strait, it has limited passage by charging high tolls and allowing selective transit, including continued exports of its own oil. Analysts say Trump’s strategy is to cut off a key revenue stream for Iran by halting its oil shipments entirely, thereby weakening its ability to fund military operations.
However, such a move carries significant global risks, as the strait is a vital route for international oil supply, and any disruption could trigger sharp increases in energy prices worldwide.
The US has so far avoided a full blockade to prevent market shocks, even allowing some Iranian oil to flow and temporarily easing sanctions to stabilize prices. Trump’s latest threat signals a shift toward maximizing economic and strategic leverage over Iran, even at the cost of potential volatility in global oil markets.
