This document explains how GoldSilver.ai calculates the price premium of precious metals traded in Shanghai relative to international benchmark prices.
The Shanghai premium measures the price difference between domestic precious metal prices in China and internationally traded benchmark prices.
It is used to quantify regional price divergence between the Chinese physical metals market and global wholesale markets.
GoldSilver.ai compares domestic Shanghai prices to internationally traded benchmark prices representing global wholesale metal markets.
These benchmarks reflect international trading activity in major financial centres such as London and New York and serve as the global reference price for wholesale metal.
Domestic Shanghai prices are typically quoted in Chinese yuan, while international benchmark prices are quoted in US dollars.
To calculate the premium, prices must be converted into the same currency using prevailing foreign exchange rates.
The Shanghai premium reflects price divergence between regional and international markets. It does not represent a trading cost or fee, but rather a market pricing difference.
For explanation of the economic drivers and market meaning of Shanghai price premiums, see the live Shanghai price pages.
