US sector ETFs open mostly lower; regional banks ETF down 1%

The uniformity of the early weakness matters more than the size of any single move: when regional banks, broader banks and utilities slip together, it reads less as a sector story than as a broad risk-off opening, with utilities — typically a defensive holding — failing to decouple. Regional banks remain the segment most sensitive to deposit and credit sentiment, so their underperformance is the line worth tracking. Whether utilities keep falling alongside cyclicals, rather than catching defensive bids, is the open question for the session.
