Futures indexes are in the red ahead of the Wall Street open, with PPI data on the horizon.

US futures are in the red ahead of Wall Street's opening, with market attention focused on the US Producer Price Index (PPI) data to be released at 15:30 GMT. Concerns surrounding Trump's trade policies continue to be a major focal point in the markets.

Trump's warning that the US would retaliate with a 200% tariff on all wine imports from the EU if they do not immediately lift their tariffs on whiskey has intensified selling on Wall Street. The producer prices are expected to rise by 0.3% month-over-month and 3.3% year-over-year in February, following a 3.5% annual increase in January. Currently, S&P 500 futures are down 0.27%, Dow Jones futures are down 0.20%, and Nasdaq 100 futures have decreased by 0.5%.
