US stock futures open lower, with Wall Street bracing for a potentially weak start to September as Treasury yields rise. Several outlets attribute the decline to a jump in yields, which can reduce the appeal of equities relative to bonds and tighten financial conditions.

The coverage also points to broader, seasonal context: September has historically been a challenging month for equities. In this framing, investors remain cautious at the turn of the month, monitoring yields and other macro signals that could influence market direction. While outlets emphasize yields as the immediate driver, they also situate the move within recurring patterns and expectations around September’s market performance.
