Global Market Today: Asian stocks dip at open as oil edges higher

Asian stocks opened lower, with MSCI regional gauge falling as much as 0.2%, while S&P 500 futures edged down after megacap tech stocks slid and US bond yields rose. Brent crude traded above $78 per barrel as the US issued a 60-day license allowing Iran to sell oil internationally, supporting diplomatic efforts. Concerns about return on investment from massive AI spending by hyperscalers and Federal Reserve Chair Kevin Warsh's hawkish tone also weighed on sentiment, while SpaceX slid around 16% on a planned bond sale of at least $20 billion.
