According to Deep Tide TechFlow news on May 15, as reported by Jin10, the U.S. retail sales data and producer price index will be released tonight at 20:30. Following that, at 20:40, Federal Reserve Chairman Powell will deliver a speech. The market expects Powell to provide signals for interest rate cuts, but analysts believe he is more likely to focus on evaluating the Federal Reserve's monetary policy framework. From a technical perspective, if gold cannot return to the $3168-$3170 range, it may further dip to $3100. Investors' expectations for interest rate cuts by the Federal Reserve this year have now dropped to about 50 basis points, far below last month's expectations.
