Oil prices surged and Asian stock markets declined Monday following an announcement by US President Donald Trump regarding a naval blockade of Iran.
Blockade Announcement Rattles Markets
Brent crude, the international benchmark for oil prices, rose more than 8 percent on Sunday, exceeding $103 a barrel. This marked the first time the price surpassed $100 since Tuesday, when it reached $111 a barrel.
President Trump announced the planned blockade after ceasefire talks between US and Iranian officials collapsed over the weekend. But, US Central Command later clarified that the blockade would focus on vessels traveling to and from Iran, stating that other maritime traffic would not be impeded.
Traffic Already Reduced
The planned US action follows a period of already restricted traffic through the Strait of Hormuz. After US-Israeli strikes on Iran prompted a de facto blockade by Tehran, only 17 vessels crossed the strait on Saturday, a significant decrease from the roughly 130 daily transits recorded before the conflict began more than six weeks ago.
Asian markets reacted negatively to the news. Japan’s Nikkei 225 fell 0.9 percent in morning trading, and South Korea’s KOSPI dropped by more than 1 percent. US stock futures also experienced a decline, falling approximately 0.8 percent.
