The LBMA Silver Price – the crucial daily benchmark used by producers and traders around the world to settle silver products and derivatives contracts – was set at $13.58 per ounce.

At the time of the auction, which begins at 12 noon London time, the spot price was at $14.42 per ounce while the futures price on the CME was at $14.415, leaving a number of market participants extremely confused as to what has happened.

"Unfortunately, it is not [a mistake]," Ole Hansen, head of commodity strategy for Saxo Bank, told FastMarkets. "This could be the end of the fix. It took 14 minutes to find a fix – they obviously found a fix way off of the market."

The difference between the two was nearly six percent but the benchmark cannot be changed, a person familiar with proceedings told FastMarkets.
