US benchmark equity indexes ended higher Tuesday as Wall Street evaluated remarks by a Federal Reserve governor and the latest economic data.

* Fed Governor Lisa Cook said that while the US economy remains on "a firm footing," uncertainty has increased significantly since the start of the year as changes to trade policy begin to weigh.

* "I do not express views on the (Trump) administration's policies. But I do study the economic implications, which appear to be increasing the likelihood of both higher inflation and labor-market cooling," Cook said. "Heightened uncertainty poses risks to both price stability and unemployment."

* The Organization for Economic Co-operation and Development lowered its global and US economic growth projections for 2025 and 2026 amid significant trade barriers, elevated policy uncertainty and deteriorating confidence. The latest outlook assumes that tariff rates as of mid-May remain intact despite ongoing legal challenges, according to the report.

* "Weakened economic prospects will be felt around the world, with almost no exception," OECD chief economist Alvaro Pereira said. "Lower growth and less trade will hit incomes and slow job growth."

* July West Texas Intermediate crude oil closed up $0.93 to settle at $63.45 per barrel, while August Brent crude, the global benchmark, was last seen up $1.07 to $65.70. Wildfires cut into supply from Alberta's oil sands and talks to end Iran's nuclear ambitions and lift sanctions on its exports faltered.

* Dollar General (DG) shares jumped 16% after the discount retailer raised its full-year revenue and same-store sales growth outlook as it recorded better-than-expected fiscal Q1 results.

* FactSet Research Systems (FDS) appointed Sanoke Viswanathan as chief executive officer, effective in early September, replacing Phil Snow. FactSet shares fell 4.8%.
