U.S. stock index futures were slightly higher Tuesday morning, following a volatile session on Wall Street as an intensifying trade dispute exacerbated concerns about global growth.

At around 01:45 a.m. ET, Dow futures rose 9 points, indicating a positive open of more than 52 points. Futures on the S&P and Nasdaq were both seen slightly higher.

Market focus has shifted to monetary policy this week, with a flurry of central banks across the world set to announce whether to adjust interest rate settings.

Meanwhile, comments from the Federal Reserve on Monday raised expectations that the U.S. central bank is moving closer to a rate cut.
