Shanghai Premium Calculation Methodology

This document explains how GoldSilver.ai calculates the price premium of precious metals traded in Shanghai relative to international benchmark prices.

Definition

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.

Core Calculation Formula

Shanghai Premium = Domestic Shanghai Price − International Benchmark Price

Percentage Premium

Premium % = (Shanghai Price − International Price) ÷ International Price × 100

International Benchmark Reference

GoldSilver.ai compares domestic Shanghai prices to internationally traded benchmark prices representing global wholesale metal markets.

  • Gold benchmark reference: XAU/USD
  • Silver benchmark reference: XAG/USD

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.

Currency Normalisation

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.

Data Inputs

  • Shanghai domestic precious metal price benchmarks
  • International benchmark price references (XAU/USD, XAG/USD)
  • Foreign exchange rates for currency conversion

Interpretation

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.
