Canadian stocks changed little on Monday after the U.S. seizure of an Iranian vessel threatened the ongoing two-week ceasefire, triggering renewed war concerns in the gulf and driving crude oil supply disruption concerns.
After opening below the previous week's close, today the benchmark S&P/TSX Composite Index regained ground early in the session but quickly lost the momentum. The index traded modestly lower for much of the day before gaining towards the end of the session and settling at 34,360.03, up by 13.74 points (or 0.04%).
Six of the 11 sectors posted gains today, with the healthcare sector leading the pack.
The Middle East conflict took different turns over the past few days, leading to a surge in oil prices today.
The two-week ceasefire, which U.S. President Donald Trump announced earlier this month, is set to lapse on April 22.
To utilize this period to find ways to chart a course for peace talks in future, a U.S. delegation led by Vice President JD Vance met its Iranian counterparts in Islamabad, Pakistan. However, the negotiations did not yield any breakthrough with Trump calling the meet "a failure".
Quickly, Trump ordered U.S. naval forces stationed near Iran to block all vessels transiting to and from Iranian ports in an effort to cripple Iran's economy (which is largely dependent on oil exports), and thereby compel the nation to agree to U.S. terms and conditions.
In retaliation, Iran tightened its control over the Strait of Hormuz. As a result, oil and energy carrying ships remained stranded at sea.
This weekend, Trump confirmed a second round of negotiations with Iran with a team headed by Vance heading to Pakistan on Monday, renewing expectations of a resolution to the crisis in the near-term.
Shipping analytics firm Kpler stated that over 20 vessels passed through the strait on Saturday.
However, yesterday, Trump announced via Truth Social that U.S. naval forces seized an Iran-flagged vessel, Touska, that did not respond to "fair warning calls" to halt.
Accusing U.S. forces of attacking and boarding its ship, Iran called it a blatant act of violation of the proclaimed ceasefire and vowed a fitting response.
In an interview with Fox News, Trump reaffirmed that an agreement with Iran could be signed today. ABC News quoted Trump as stating that a deal with Iran will happen one way or another.
Trump also threatened Iran to soon come to a deal with the U.S., failing which U.S. forces would destroy Iranian bridges and power plants.
However, uncertainty remains on when the negotiations will happen as Iran has not yet confirmed sending its delegation, adding that the U.S. is placing "excessive demands," while Reuters cited an anonymous source confirming that Vance is yet to depart for Pakistan.
Reuters and the New York Post separately quoted anonymous Iranian officials as stating that Iran is considering attending the talks.
