Core Viewpoint - The recent fluctuations in the gold market are attributed to a combination of geopolitical tensions, trade tariff developments, and monetary policy discussions, highlighting gold's multifaceted nature as a commodity, financial asset, and currency [5]. Commodity Attributes - The impact of tariffs on gold prices has become more pronounced, particularly due to the U.S. imposing a new "reciprocal tariff" of 39% on Swiss gold bars, which led to a temporary halt in gold shipments from Swiss refineries to the U.S. [7] - A subsequent reversal occurred when the White House announced an exemption for imported gold bars from tariffs, causing a significant drop in the New York-London gold premium, although it remained above normal levels, indicating ongoing market uncertainty [7]. Financial Attributes - The market has experienced fluctuating sentiments regarding U.S.-Russia relations, with optimism about potential talks being tempered by President Trump's comments, reflecting the complexities of geopolitical dynamics and their influence on risk sentiment [9]. - The ongoing conflict in Ukraine and central bank gold purchases are contributing to a shift away from globalization, with the likelihood of immediate peace agreements being low due to competing interests among major powers [9]. Monetary Attributes - The independence of the Federal Reserve is not expected to be a major market driver in the short term, as current Chairman Powell's term is nearing its end, and the selection of a new chair will take time [11]. - A potential risk lies in the upcoming FOMC meeting, where a rate cut could lead to the reintroduction of interest-bearing Treasury issuance, possibly pushing 10-year U.S. Treasury yields towards 5%, which would exert downward pressure on gold prices [11]. Market Outlook - Despite short-term expectations of geopolitical easing and tariff exemptions boosting risk sentiment, the trends of de-globalization and weakening dollar credibility persist, making the gold-silver ratio at 85-90 more attractive for long positions compared to high-priced gold [13].
