Gold Price Parity Formula

USD per gram = USD per troy oz ÷ 31.1034768

Target Parity = USD per gram × FX × Target Weight × (Target Purity ÷ Reference Purity)

The parity model assumes the reference and target quotations represent equivalent gold exposure after the stated purity and unit adjustments.

What Gold Price Parity Means

Parity is a normalized theoretical price, not a guaranteed transaction price. A real market can differ because of taxes, premiums, dealer spreads, logistics, liquidity and other commercial factors.

Why Purity Matters

A 75% gold item should not be compared directly with a 99.99% benchmark by gross weight. The purity adjustment converts the reference metal content into an equivalent target basis.

Use matched quotations and timestamps when analyzing short-lived cross-market differences.

Frequently Asked Questions

Can I compare a 24K benchmark with an 18K product?

Yes, provided the target price is interpreted as the total price for the entered target weight and purity.

Does parity include retail premiums?

No. It is a normalized benchmark.

Is a parity gap automatically arbitrage?

No. Transaction and market constraints can eliminate an apparent gap.
