Tonight, the global financial market's attention will be focused on the Federal Reserve's interest rate decision, which is expected to have a significant impact on the gold market. The market generally expects the Federal Reserve to announce a rate cut at this meeting, but the magnitude of the cut -25 basis points or 50 basis points - remains uncertain. This decision will not only affect the value of the US dollar, but also indirectly impact the gold market through its impact on global economic expectations.
