    Oil surges 5% on Iran sanctions shift; Nasdaq drops 5%

    Question

    Oil surges 5% on Iran sanctions shift; Nasdaq drops 5%

    Direct answer

    A sudden shift in U.S. policy regarding Iran sanctions has sent oil prices up 5%, creating an immediate inflationary shock. This has triggered a massive 5% selloff in the Nasdaq, as investors flee high-valuation tech stocks in favor of energy and defensive positions. The volatility was exacerbated by a circuit breaker in South Korea following Samsung's earnings, highlighting the fragile state of global tech sentiment despite strong fundamental data.
