The Iran-U.S. situation experienced a dramatic turnaround within 48 hours, shifting from "on the brink of war" to "signals of a ceasefire," triggering intense volatility in global markets. On April 1, Iranian President Ebrahim Raisi sent a clear signal that he is "ready to end the war but hopes to obtain guarantees," prompting the White House to immediately announce that President Trump will deliver a nationwide address on the Iran situation at 9 p.m. Eastern Time on April 2. This news drove U.S. stocks higher across the board— the S&P 500 rose about 2.9%, the Nasdaq gained approximately 3.8%, and crypto-related stocks also strengthened, with Coinbase up 8.60% and Robinhood up 6.61%. Bitcoin retook the $68,000 level, Ethereum broke through $2,100, gold and silver moved upward in tandem, while crude oil prices fell in response.
