上海銀価格、欧米市場を11ドル上回る過去最高プレミアムを記録

The assessment of "likely_true" with high confidence is based on several consistent, albeit low-authority, sources making a direct and specific claim, supported by broader market context and a complete lack of contradictory evidence.The primary evidence comes from The Kobeissi Letter, a financial commentary service, which explicitly and repeatedly states across multiple social media posts that the Shanghai silver price premium over Western prices reached a record of $11/oz. This consistency from a single source, while not definitive, lends weight to the claim's authenticity.Further support, though indirect, comes from a post by a precious metals dealer. It confirms the existence and significance of the silver price premium in Shanghai (SHAGPM) over London (LBMA), validating that this is a real and monitored market dynamic. This makes the claim of a record premium plausible. Additional sources provide context about a speculative rally in silver and high physical demand in China, which are logical drivers for such a significant price discrepancy between Eastern and Western markets.Critically, none of the provided sources offer any information that contradicts the statement. The primary weakness in the evidence is the absence of confirmation from a high-authority primary data source like Kitco or a major financial news outlet within the provided summaries. The sources making the direct claim are financial commentary services on social media, which carry lower authority than established data providers. However, the specificity of the "$11" and "record high" claim, combined with corroborating context and no refuting evidence, makes it highly probable that the statement is accurate.
