Gold ETFs have seen significant inflows. If gold fails to return above $3300 per ounce, it may test June lows [4][6]. - **Silver**: Strong US employment data and tariff - related inflation concerns have influenced the market. The supply - demand gap in 2025 is expected, but weak industrial demand and high inventories limit price increases.
