黄金守住隔夜涨幅稳于4100美元上方，美国9月PPI上升6.3%

The 6.3% increase in U.S. PPI in September showed that upstream inflationary pressures are still strong, but gold still held on to overnight gains and remained above $4,100, indicating that the market's short-term reaction to inflation data has not weakened the resilience of precious metals. It is worth noting that this price performance may reflect that traders pay more attention to real interest rate expectations or risk aversion than a single inflation indicator. It will be necessary to observe how the market digests the interaction between this data and the Fed's policy signal.
