On Wednesday (February 28th), the US dollar index showed an inverted V-shaped trend, continuing to strengthen in the Asian and European markets before falling all the way back and finally closing up 0.125% at 103.94. The benchmark 10-year US Treasury yield fluctuated and fell, closing at 4.271%, while the 2-year US Treasury yield, which is most sensitive to the Federal Reserve's policy rate, closed at 4.644%.

Gold prices rose slightly on Wednesday (February 28), with the United States slightly reducing its fourth quarter economic growth rate to provide support. However, the increase in gold prices was limited as traders focused on key economic data and comments from Federal Reserve officials on the rate cut schedule.

US crude oil futures rose and fell on Wednesday (February 28), despite news that OPEC+may extend production cuts supporting oil prices to nearly three and a half months high. However, Federal Reserve decision-makers insisted on not lowering interest rates in the near future, and the increase in US crude oil inventories further put pressure on oil prices, causing them to recoup their gains in the late trading session.
