What Is the Difference Between London Silver and COMEX Silver?

2026-11-12 14:26:22 | 44

London silver and COMEX silver are both important parts of the global silver market, but they differ in their trading methods, pricing mechanisms, and delivery arrangements. In simple terms, London silver is primarily traded over the counter (OTC), with a focus on spot transactions, while COMEX silver mainly refers to standardized silver futures contracts traded on COMEX, part of CME Group. Although prices in the two markets influence each other, they are not always identical.

What Is the Difference Between London Silver and COMEX Silver

Trading Methods: OTC vs. Exchange-Traded Markets

London silver is primarily traded in the London OTC precious metals market. Buyers and sellers typically conduct transactions through market participants such as banks and market makers, rather than through a centralized exchange. Transactions can be settled through either unallocated or allocated accounts.

For retail traders, the XAGUSD product shown on platforms such as MT4 and MT5 is in some cases offered in the form of a CFD. This does not mean that retail traders are directly participating in the LBMA wholesale spot market.

COMEX silver, by contrast, is traded through a centralized exchange. All orders are entered into the CME Globex electronic trading system, where market participants trade standardized futures contracts. Each contract has clearly defined specifications, including its trading unit, quotation method, delivery months, and delivery rules. Trading and clearing are also conducted under the exchange's established procedures.

The key distinction is that London silver is primarily an OTC spot market, whereas COMEX silver is primarily a market for standardized futures contracts.

Pricing Mechanisms and Delivery Arrangements

Prices in the London silver market are primarily determined by bilateral quotes and transactions between market participants, with the LBMA Silver Price serving as an important international benchmark. Independently administered by ICE Benchmark Administration (IBA), the benchmark is established through an electronic auction at 12:00 London time on each London business day and is quoted in US dollars per troy ounce.

COMEX silver prices, on the other hand, are determined by buy and sell orders and executed trades on the exchange. Since silver futures are available in different delivery months, prices can vary from one contract to another. Traders should therefore pay attention to the specific futures contract when checking market prices.

In terms of delivery, the London market uses unallocated and allocated accounts to manage silver holdings and ownership interests. Standard COMEX silver futures contracts have a trading unit of 5,000 troy ounces and provide for physical delivery. Therefore, it is incorrect to assume that every London silver transaction requires the physical movement of silver bars, or that COMEX silver futures can only be settled in cash.

Why Do London Silver and COMEX Silver Prices Differ

Why Do London Silver and COMEX Silver Prices Differ?

Prices in the two markets are generally closely correlated, but their quotations do not necessarily match exactly.

The main reasons include:

· Differences in time horizon: London spot quotations reflect prevailing market conditions, while COMEX futures prices also factor in contract maturity and the cost of carrying a position.

· Different delivery locations: The two markets have different delivery locations, transportation requirements, and delivery arrangements.

· Changes in supply, demand, and liquidity: Shifts in physical supply, delivery demand, and trading activity in a particular market can all affect prices.

· Financing and holding costs: Interest rates, storage, insurance, and financing costs can influence the spread between spot and futures prices.

For example, suppose the London spot silver price is quoted at USD 53.02 per troy ounce, while a COMEX silver futures contract for a particular delivery month is quoted at USD 52.97 per troy ounce. The difference is USD 0.05 per troy ounce. This spread can be analyzed in terms of the futures contract's maturity, financing costs, and delivery conditions. It does not necessarily mean that either market is quoting an incorrect price.

Which Silver Price Should Investors Follow?

Prices in the two markets can be used as references for one another, but one market's quotation should not be applied directly when placing orders in the other. In actual trading, investors should refer to the prices displayed on their trading platforms and consider the specifications of the products they are trading.

Upway Global provides OTC spot silver trading services, allowing investors to trade on silver price movements through its trading platforms. When choosing a trading product, investors should look beyond international silver prices and understand the platform's pricing method, trading costs, and risk management rules. This helps avoid applying the trading mechanisms of the London or COMEX markets directly to other silver products.
