The mixed showing underscored the tense market mood as investors this week seesawed between hope for an imminent end to the war and fear that it might not come soon.
“The thing is, a ceasefire is a funny term to use in conjunction with a blockade and rolling tensions and animosities,” said Vishnu Varathan, Mizuho’s head of macro strategy for APAC.
Iran on Thursday flaunted its tightened grip over the key Strait of Hormuz with a video of commandos in a speedboat storming a huge cargo ship, while US President Donald Trump said he had ordered the Navy to “shoot and kill” Iranian boats laying mines in the strait, and step up demining activity.
Trump’s comments came just days after he said he would indefinitely extend what had been a two-week ceasefire with Iran to allow for further peace talks.
“It’s not going to be a linear de-escalation of violence and oil prices and volatility around the entire supply shock,” said Varathan.
“[Investors] have just been looking for excuses to put on optimistic trades opportunistically. I don’t think anybody in the market truly believes that this will be over in a week or two.” (Reuters/Xinhua)
