What Is a Premium?
When you buy a 10 oz gold bar, the price you pay is usually the spot price of gold (per troy ounce, times 10) plus a premium. The premium is the extra amount that covers the cost of refining, assaying, minting or casting, packaging, distribution, and dealer margin. It is often expressed as a percentage over spot or as a dollar amount per ounce.
The World Gold Council and other sources use "premium" in this way when discussing physical gold demand. Premiums vary by product size, brand, and market conditions. They are not set by a single authority; they emerge from dealer competition and supply and demand.
Why 10 oz Bars Have Lower Premiums Than 1 oz
Larger bars tend to have lower per-ounce premiums because many costs are fixed per bar rather than per ounce. One assay certificate, one set of packaging, one shipment, and one dealer transaction apply to the whole bar. Spreading those costs over 10 ounces instead of 1 ounce reduces the premium per ounce. Refining and casting costs also scale in favor of larger bars.
Under normal market conditions, 10 oz bars from recognized refiners often trade at premiums in the 1.5% to 3% range over spot. 1 oz bars might be 3% to 8% or more. Kilo bars can be 1% to 2%. These ranges are illustrative; actual premiums depend on dealer, brand, and timing.
What Drives Premiums Higher or Lower
Premiums widen when demand for physical bars rises relative to supply, or when dealers face higher funding or inventory risk. Geopolitical or financial stress often increases retail demand for gold; at the same time, refiners and distributors may have limited immediate supply. In those periods, premiums on 1 oz and 10 oz bars can rise. Historically, 1 oz premiums have been more volatile than 10 oz, sometimes spiking into double digits while 10 oz premiums increase more moderately.
Premiums tighten when demand normalizes, supply catches up, and dealers compete for orders. Calm markets and normal inventory levels usually support premiums at the lower end of the typical range. Seasonal or event-driven demand (e.g., year-end, tax-related selling) can cause shorter-term moves.
Quality and Brand
Bars from LBMA-accredited refiners and well-known mints (e.g., Royal Mint, U.S. Mint for coins; PAMP, Valcambi, Perth Mint for bars) often command a small premium over generic or lesser-known products. That reflects recognition, liquidity, and buyer preference. For 10 oz bars, the brand spread is usually narrower than for 1 oz products.
How to Use This Information
Premium levels are informational. They help you compare dealers and products and understand why the all-in price for a 10 oz bar differs from 10 times the spot price. For current spot and product pricing context, see a gold pricing page. Shopping multiple dealers and buying when markets are not in crisis mode can help you obtain competitive pricing. Avoiding hardcoded price expectations and using current market price references (e.g., spot plus a typical premium range) keeps analysis educational rather than promotional.
