Trump's tariffs may rise to 15% this week, and US stock futures will give up the "peace talks" positive gains. On March 4th, according to Golden Ten Data, US stock index futures gave up their previous gains in early Wednesday trading. Previously, the Trump administration signaled that a 15% global import tariff may take effect this week, adding new disruptive factors to the already volatile market caused by the US Iran war. At present, traders are still digesting the impact of the war on oil prices and inflation, which had put pressure on the market on Tuesday. Earlier, boosted by a report in The New York Times, futures briefly rose. The report stated that Iranian intelligence personnel have contacted the Central Intelligence Agency of the United States to discuss the conditions for ending the conflict. Michael O'Rourke, Chief Market Strategist at Jones Trading, said: "Two days of buying on dips have limited the S&P 500 index's decline this week. The mechanical reaction of the stock market to oil prices has squeezed out previous anxieties about AI and private credit from the market mentality. ”Goldman Sachs Chairman Solomon was surprised by the market's "mild" response to the situation in the Middle East. Wall Street strategists warn against relying on so-called 'Trump put options' on the issue of the US Iran war, as the consequences of the conflict may be difficult to control.
