While none of the provided sources directly report on an instance where President Trump halted tariffs on the EU, they overwhelmingly and consistently establish a clear economic relationship: the threat or imposition of tariffs by the Trump administration caused the prices of gold and silver to rise. Several high-authority sources, including the BBC and Business Insider, explicitly state that prices for these precious metals soared in response to trade standoffs and tariff threats. This market behavior is standard, as gold and silver are considered 'safe-haven' assets that investors flock to during times of economic and geopolitical uncertainty.The user's statement describes the logical inverse of this well-documented phenomenon. If increasing trade tensions and tariff threats cause prices to rise, it is highly probable that a reduction in those tensions, such as halting new tariffs, would cause prices to fall as market uncertainty decreases. The provided sources strongly support the underlying economic principle of the statement. Therefore, based on the consistent evidence of how these markets reacted to tariff news, the statement is very likely to be true.
