Despite the war disrupting the market, the confidence of large American corporate CEOs in the economy remains strong.

Despite global uncertainty and the war with Iran pushing up energy prices and disrupting markets, the confidence of chief executives of large American companies rose in the first quarter. According to the survey results released on Wednesday, the Business Roundtable's "CEO Economic Outlook Index" rose 9 points to 89, the highest level in over a year. A reading above 50 indicates growing expectations for capital spending, sales, and hiring in the next 6 months. The survey was conducted from February 23 to March 6, collecting responses from 169 CEOs. The survey was conducted after the U.S. Supreme Court overturned multiple broad tariff measures by President Donald Trump, and during the attacks by the U.S. and Israel on Iran. "These results demonstrate the impact of last year's tax reform, responsible deregulation, and the resilience of the U.S. economy," said Business Roundtable chairman and Cisco chairman and CEO Chuck Robbins in a statement. "We look forward to continuing to work with the Trump administration and Congress in the coming months to promote policies that will bring long-term growth." The survey showed improvements in companies' hiring plans, but still about one-third of CEOs said they plan to reduce the number of employees in the coming months.
