Affected by news that the US suspended military operations against Iran, international oil prices plummeted on January 15, recording the largest single-day drop since last October. West Texas Intermediate crude futures for February delivery on the New York Mercantile Exchange fell $2.83 to close at $59.19 a barrel, a drop of more than 4%; Brent crude futures also fell $2.76 to close at $63.76 a barrel, a decrease of 4.12%. Previously, due to unrest in Iran and related remarks, the market worried about supply chain disruptions, and oil prices had risen for two consecutive trading days.

The precious metals market fluctuated simultaneously. Silver prices pulled back from historical highs, plunging 7.3% intraday before recovering some losses, with a cumulative gain of more than 20% in the previous four trading days. Gold prices also edged lower, mainly affected by investor profit-taking and news that the US will not impose additional tariffs on key minerals. Deutsche Bank analysts pointed out that the market regards relevant remarks as a detente signal, but uncertainties remain in the Iranian situation, and subsequent geopolitical developments will continue to dominate the trends of energy and precious metals prices.
