What caused the stock market collapse today?
The bleeding markets came as a result of the failure of the US-Iranian talks in Islamabad over the weekend. US Vice President and chief negotiator J.D. Vance announced in a press conference on Sunday that he and his team would return to Washington without an agreement as Iran refused to accept what he described as America’s “best and final offer.”
Meanwhile, Iran blamed the failure on “unreasonable demands” made by the United States, which included references to the Strait of Hormuz and Tehran’s nuclear programme.
Later in the day, US President Donald Trump criticized Iran over the talks and announced that the US Navy would begin a blockade of ships entering and exiting the Strait of Hormuz starting at 10 a.m. (local time) on Monday.

He said that he did not care if Iran returned to the table or not, adding that Tehran’s capabilities had been exhausted and defeated. “Iran is in a very bad situation,” he told reporters on Sunday evening.
“With the failure of US-Iran peace talks and Trump announcing the US naval blockade in the Strait of Hormuz, uncertainty has risen and with it crude oil prices. Brent at $103 has emerged as another threat to the economy and markets,” VK Vijayakumar, chief investment strategist at Geojit Investments Limited, told news agency PTI.
This development “triggered a clear sense of risk aversion in global markets,” said Hariprasad K, research analyst and founder of Livelong Wealth.
In addition, Asian markets, including South Korea’s benchmark Kospi and Japan’s Nikkei 225, also traded lower.
