Stock futures erased earlier gains after Treasury Secretary Scott Bessent signaled that 15% tariffs on US imports would likely take effect this week. The announcement came as markets grappled with the fallout from the Iran conflict, which has already sent oil prices higher and weighed on investor sentiment.

S&P 500 futures remained flat at 8 a.m., while Nasdaq 100 contracts rose 0.2%. The index has slipped 0.9% since the US and Israel first struck Iran over the weekend. Broadcom Inc.'s earnings after the close remain a key focus for traders assessing technology sector strength.

Market strategists noted the surprising resilience of equities despite Middle East tensions. Michael O'Rourke of JonesTrading observed that dip buying has limited losses, while David Solomon of Goldman Sachs expressed surprise at the market's "benign" reaction. Traders now await the 8:15 a.m. labor market report and S&P Global PMI data at 9:45 a.m. before parsing Broadcom's earnings for clues about tech sector demand.
