According to CoinMeta, investment and live reporting, a summary of American foreign exchange news on September 1st indicated that despite the commencement of trade, the war in Iran had not ended, and fighting had resumed. The US dollar rose, Treasury yields climbed, the US stock market fell, and crude oil prices soared above $90 due to the intensification of the US-Iran conflict, increasing market concerns about disruptions to Middle Eastern oil supply. The United States counterattacked attacks aimed at US military and commercial vessels, and the key shipping route through the Strait of Hormuz once again became a focal point of market attention. Rising energy prices exacerbated inflation concerns, while the latest manufacturing data showed a slowdown in growth, with cost pressures remaining. This is an unfavorable combination for both the Federal Reserve and investors. The US dollar strengthened against all major currencies, with the largest gains against the New Zealand dollar and Swiss franc. The euro performed relatively well but still declined. US bond market yields generally rose, with the 10-year Treasury yield climbing to 4.80%, approaching the psychological barrier of 5%. Against this backdrop, the US stock market faced pressure, with the Nasdaq and Russell 2000 indices leading the declines, and technology and software stocks performing poorly.
