US Stock Markets Live Updates: Dow futures tank 800 points on Greenland tariff crisis

US Stock Market Live Updates: Futures on Wall Street have tanked ahead of the resumption of regular trading after Monday's holiday. The Dow Jones futures are down nearly 750 points, while those on the S&P 500 are down 110. The Nasdaq futures are down close to 500 points. This will be the first reaction of Wall Street to US President Donald Trump's threat of imposing 10% tariff on February 1 on European allies for non-compliance for his plans to acquire Greenland. That tariff is set to rise to 25%

by June if a deal is not reached by then. The European members are also preparing a set of countermeasures against the US ahead of an important meeting tomorrow.

While global markets remain in risk-off mode, appetite for haven assets has only increased. Gold and Silver prices have made new highs in the global markets. All eyes will also be on the US Supreme Court today as to whether or not it hears the legality of Trump tariffs.

Watch this space for all the Live updates on Wall Street moves, global market reactions and key developments shaping US trade policy.
