Quantify how much a regional gold price differs from a comparable global benchmark after converting the benchmark into the same currency and unit.
This structure lets you separate a simple FX conversion from any additional benchmark adjustment you deliberately model.
Regional gold prices can differ from international benchmarks because of local supply and demand, taxes, import restrictions, premiums, logistics and market structure. The World Gold Council publishes local premium/discount series for India and China and describes them as directional, theoretical measures. 1
The measured gap can combine several market effects. A premium percentage is an observation about prices under your selected assumptions, not a single identified fee.
Yes. That is a regional discount versus the chosen benchmark.
Some analyses want to include a known benchmark-specific adjustment separately from the FX conversion.
No.
