The yield on the 10-year Treasury note rose 3 basis points to 4.79% early Tuesday. Higher yields make borrowing more expensive and put pressure on stock valuations.
Kathleen Brooks, research director at XTB, said investors had grown used to the Iran conflict being more of an economic standoff. The return of actual military strikes adds a new risk for markets to price in.
Investors are watching a busy week of economic data. The Job Openings and Labor Turnover Survey releases Tuesday, giving the first look at the labor market before Friday’s monthly jobs report.
Manufacturing data from S&P Global and the Institute for Supply Management will also drop this week.
On the earnings front, Dell and Palo Alto Networks are set to report results. Their numbers could show how companies are spending on technology and cloud services.
Stock futures entered September with double-digit year-to-date returns still intact. But rising oil, higher yields, and a shaky geopolitical backdrop have put investors on guard as the historically weak month begins.
