The Tadawul All Share Index closed 0.40% in the red on Tuesday as Iran-aligned Houthis declared a naval blockade on Saudi maritime traffic in the Red Sea, threatening global energy supplies and trade in the Middle East.
Crude oil soared to $90.778 per barrel as traders balanced escalating conflict and volatility in the Middle East amid news of a potential 10-day ceasefire proposed by mediators to resume negotiations between Iran and the US.
"With the Gulf's primary maritime outlet largely closed, the market is increasingly dependent on Saudi Arabia's East-West pipeline and Red Sea terminals to maintain export flows. Any disruption at Bab el-Mandeb would therefore threaten not only Saudi shipments but one of the few remaining routes capable of compensating for the severe reduction in Hormuz traffic," Rystad Energy senior vice president and head of geopolitical analysis Jorge Leon commented. "If a ceasefire does not materialize and Hormuz remains largely closed while the Houthi threat to Red Sea shipping intensifies, the risk of a significant rebound in oil prices would be substantial."
