The United States and Iran have resumed a cycle of direct military attacks, triggering a closure of the Strait of Hormuz and a sharp decline in maritime traffic. According to reports from UOL Notícias and Correio da Manhã, this escalation involves new waves of U.S. strikes against Iranian targets, while Valor Econômico confirms that shipping volume through the Strait of Hormuz has dropped to its lowest level in five weeks.
Strait of Hormuz Closure and Global Shipping Disruptions
Iran has moved to close the Strait of Hormuz as part of its response to the intensifying conflict with the U.S., according to O POVO+. This strategic move targets one of the world’s most critical oil transit chokepoints.

The impact on global trade is already measurable. Valor Econômico reports that traffic through the strait has fallen to the lowest level seen in five weeks. Because a significant portion of the world’s petroleum passes through this narrow waterway, any prolonged closure typically triggers volatility in global energy markets.
Did you know? The Strait of Hormuz is the only operational exit for oil exports from Saudi Arabia, Iraq, the UAE, and Kuwait, making it a primary lever for Iranian geopolitical pressure.
U.S. Military Capacity and the Risk of Attrition
The U.S. has launched a new wave of attacks against Iran, as detailed by UOL Notícias. However, the intensity of this engagement is creating internal concerns regarding long-term readiness.
According to R7, the intensification of this war puts the overall military capacity of the United States at risk. The report suggests that the resource drain and operational tempo of the current conflict could compromise the U.S. ability to respond to other future conflicts globally.

| Resource Drain | Risk to future military capacity | R7 |
Future Trends in Middle East Maritime Security
The current pattern of “exchange of attacks” noted by Correio da Manhã suggests a shift toward a war of attrition. If the Strait of Hormuz remains restricted, shipping companies will likely seek alternative routes or increase insurance premiums for “war risk” zones.
The U.S. military must balance the immediate need to neutralize Iranian threats with the strategic necessity of maintaining a global presence. As R7 highlights, the risk is not just the current battle, but the depletion of munitions and personnel required for other theaters of operation.
Pro Tip: Investors monitoring this conflict should track “Brent Crude” futures and maritime insurance rates, as these often react faster than official government statements regarding the Strait of Hormuz.
