What moves this premium

The metric large bar, 32.15 troy ounces of .999 fine silver, where metric weights are customary. Its premium behaviour has historically tracked the 100 oz bar: low per ounce in normal markets, and a wholesale-tightness signal when it rises. Together the two large bars have usually anchored the bottom of the silver premium ladder. The benchmark takes standard kilo bars of every refiner, cast or minted; themed and collector designs and graded pieces are left out where they can be identified.

The Retail Premium Index

Questions buyers ask

How many ounces are in a 1 kilo silver bar?

A kilogram of silver is 32.15 troy ounces, a little under a third of a 100 oz bar. The premium on this page is stated per ounce, as it is for every product in the index, so the kilo bar and the 100 oz bar can be read side by side.

Is the kilo bar premium different from the 100 oz bar premium?

The two have historically tracked each other closely. Both are large, plain, .999 fine bars, and both have usually sat near the bottom of the silver ladder in this index. The kilo suits buyers who think in metric weights, and that preference can move its premium slightly against the 100 oz bar in a given month.

Who makes 1 kilo silver bars?

Refiners around the world, private and government-owned, and this series averages them rather than following one maker. Kilo bars are usually cast or minted to the same .999 standard and carry the name of the refiner, the weight and often a serial number. The series reads as the market for generic kilo silver, not for one brand.

How to read this page

The Retail Premium Index publishes the average premium paid on retail orders at SD Bullion, month by month, for each benchmark bullion product. A premium is what a buyer pays above the metal value of the piece, as a share of that value; a dollar figure is shown only where the record carries it. It includes the mint's and the distributor's charges as well as the dealer's, so it is not a measure of dealer margin.

A premium can also be negative: when the metal price moves very fast, some products have sold for less than the metal in them, and the series shows that as it happened.

Where next

The Retail Premium Index is a free public resource published for educational purposes only. It is compiled from real transaction records and from market data we license, using the methods described on the methodology page, and we correct it when we find errors. It is not a price quote, an offer to buy or sell, or investment advice, and it may not match figures compiled by other dealers or from other sources, whose products, pricing and methods differ from ours. The methods, the products covered and the period covered may change over time; nothing about the continuation, consistency or method of the index is guaranteed, and any figure may be revised or withdrawn. Past premiums do not indicate future premiums. The figures come from one retailer's own records of completed orders, and for the months before March 2019 from estimates of what the metal was worth at the time of each sale.
