07:48 AM EDT, 08/11/2026 (MT Newswires) -- US equity markets were mostly trending higher before the open Tuesday as investors weigh fading optimism that the US and Iran would reach a quick resolution to their conflict and reopen the Strait of Hormuz.

In a social media post Monday, President Donald Trump demanded compensation from Iran for casualties caused by its conflicts, attacks and suppression of protests.

"I see that representatives of the Islamic Republic of Iran are asking for compensation for the damage done to them during the last five month military conflict," according to Trump. "I am likewise demanding compensation from Iran, for all of the people that they have killed and gravely wounded with their roadside bombs and many conflicts, for which they are famous, as led initially by General Soleimani."

Iranian Foreign Minister Abbas Araghchi recently said there was no possibility of restarting negotiations with the US over a peace deal until it stops violating the memorandum of understanding signed between the two countries in June and compensates Tehran for those breaches, according to Iran-based Tasnim News Agency.

Trump recently indicated to the media that he's prepared to exert greater economic pressure on Iran instead of launching another military attack.
