What Is Silver (XAG)? The Metal as a Tradable Asset

For thousands of years people have dug a soft, bright metal out of the ground and used it in two very different ways. It was money they could carry, and it is a material that carries electricity better than any other metal. The same metal ends up in coins and in solar panels, in jewelry and in the circuit boards of phones, which makes it a tradable asset whose price answers to investors and factories at once.

Owning it has always been awkward. A coin or bar comes from a dealer who charges more than the quoted price, it has to be stored and insured somewhere, and the quoted price itself depends on which screen you look at. A dealer chart, a futures exchange and a currency quote can show three different numbers in the same minute. For a trader who keeps savings in stablecoins, every one of those routes also starts with moving money back into dollars.

Crypto exchanges now list contracts that follow the price of commodities while no metal changes hands. A perpetual contract has no expiry date, settles in a stablecoin such as USDT, and lets you trade the price rising or falling from the balance you already hold.

BloFin lists silver as the XAGUSDT Perpetual, a contract that settles in USDT and allows up to 100x leverage.

What is silver (XAG)?

Silver is a precious metal, chemical symbol Ag, that trades as an asset priced in US dollars per troy ounce. In currency markets it carries the code XAG, and a dollar quote for XAG is the price of one troy ounce. Investors hold it as a store of value, while industry buys most of it as a raw material.

The code comes from the International Organization for Standardization (ISO). Its standard ISO 4217, the list of currency codes, gives silver the letters XAG and the number 961 (source: SIX ISO 4217 currency list). The X marks one of the special codes the standard keeps for supranational currencies, precious metals and other units outside the national list, and the AG comes from silver's chemical symbol. The standard defines each of these metal units as one troy ounce, so one XAG is one troy ounce of silver (source: ISO 4217 on Wikipedia). Gold works the same way: its code is XAU, which is why the two metals sit side by side on so many currency screens.

In chemistry, silver is element 47, and its English name goes back to the Anglo-Saxon word "siolfur" (source: Royal Society of Chemistry). For a trader, the more useful facts are about how it is measured and graded, because every price you will see refers to a specific weight of a specific purity.

The large bars that change hands between banks in London must be at least 999.0 parts per thousand silver and weigh about 1,000 troy ounces, roughly 32 kilograms (source: LBMA Good Delivery rules). Sterling silver, used for jewelry and tableware, is 92.5% silver with the rest usually copper (source: Royal Society of Chemistry). Price quotes always refer to fine silver, and contracts that settle in cash never hand you a bar.

Why silver is both a monetary and an industrial metal

Silver earns its price from two kinds of buyer at once. Investors buy coins, bars and funds as a store of value, the role silver played as money for centuries, while manufacturers use it in electronics and solar panels. In 2025 industrial users took about 58% of all the silver the world bought, 657.4 million ounces (source: Silver Institute, World Silver Survey 2026).

The industrial half rests on physics. Silver conducts electricity better than any other metal, which is why a little of it sits inside almost every electronic device you use (source: Silver Institute, September 2021). That demand is large but sensitive to price. Industrial use fell 3% in 2025 after four years of growth. Electrical and electronics demand was down 2%, and solar makers cut the silver in each panel as the metal got more expensive (source: Silver Institute, World Silver Survey 2026).

The monetary half is far older: silver mining had started by around 3000 BC (source: Royal Society of Chemistry). Early silver coins underpinned the economies of some ancient Mediterranean civilizations (source: Royal Society of Chemistry). The story of how silver served as money, and why governments stopped minting it, runs from those first coins to the 20th century. The investment buyers never left, though: coin and bar demand rose 14% in 2025 even as total demand slipped 2% (source: Silver Institute, World Silver Survey 2026).

Those two groups of buyers react to different news. Fear of inflation or a weaker dollar tends to send the monetary buyers into silver alongside gold, while a slowdown in factories and building work hits the industrial half, even on days when gold holds up. So silver often behaves like gold with an extra layer of business-cycle risk on top, and its swings tend to be larger in both directions.

How big the silver market is next to gold

By value the silver market is far smaller than gold's, and by weight it is far larger. At the October 30, 2026 spot prices, the 846.6 million ounces mined in 2025 were worth about $41.5 billion. Gold's 2025 output was worth about $458.1 billion, roughly 11 times as much, though miners dug up about 7.2 times more silver by weight.

Three inputs go into that comparison. The Silver Institute puts 2025 silver mine output at 846.6 million ounces, up 3% on the year (source: Silver Institute, World Silver Survey 2026), and the World Gold Council's first full-year count put gold mine output at 3,672 tonnes (source: World Gold Council, Gold Demand Trends 2025). Late in the US session on October 30, spot silver traded near $49.015 an ounce and spot gold near $3,879.90 (source: Kitco PM report, October 30, 2026).

A tonne holds about 32,151 troy ounces, because a troy ounce weighs 31.1034768 grams (source: NIST conversion factors for precious metals). That makes gold's 3,672 tonnes about 118.1 million ounces, worth $458.1 billion at $3,879.90 each. Silver's 846.6 million ounces at $49.015 come to $41.5 billion, and in tonnes they weigh about 26,332, or 7.2 times gold's output. Metals Focus, which supplies the council's mine data, has since raised its estimates by about 470 tonnes in total since 2013, so gold's 2025 figure may end up somewhat higher (source: World Gold Council, Gold Demand Trends Q3 2026).

The difference in value per ounce explains most of the gap, since one ounce of gold bought about 79 ounces of silver at those prices. A cheap ounce makes silver easy to buy in small amounts. The iShares Silver Trust alone held about 506.7 million ounces on November 2, 2026 (source: iShares Silver Trust), close to 60% of a full year's mine output. Gold versus silver as a holding compares the two metals on volatility, storage cost and what each one is for.

What the silver price is made of

The silver price is usually one of three numbers. Spot silver is the dollar price of metal for immediate delivery, and futures on the Commodity Exchange (COMEX) price metal delivered in a set month. A crypto exchange shows the mark price of a perpetual such as the XAGUSDT Perpetual, quoted in USDT. The three move together but rarely match.

Spot silver has no single exchange of its own and trades over the counter, dealer to dealer. The closest thing to an official spot reading is the LBMA Silver Price, set in an electronic auction run by ICE Benchmark Administration (source: LBMA Silver Price). The step-by-step account of how the silver price is set follows that auction and the futures market together.

The futures price comes from COMEX, which is part of CME Group. CME describes the COMEX 5,000-ounce contract as the global benchmark, and CME's smaller 100-ounce contract settles in cash against that contract's daily settlement price (source: Reuters via Kitco, August 11, 2026). The contract closest to expiry is called the front month, and it is the futures price many charts show when they say "silver".

Three things keep the numbers apart. Time is the first: a futures contract for metal months away usually costs a little more than spot, because whoever holds the metal until then pays to store, insure and finance it. Currency is the second, since the XAGUSDT Perpetual is quoted in USDT, a stablecoin that trades close to one dollar, though its price can drift slightly from it. The moment of the reading is the third. On October 30, 2026, spot silver stood near $50.080 in the Kitco morning report and near $49.015 in the late-session report, a gap of $1.065, or 2.13%, inside a single day (source: Kitco AM report, October 30, 2026; Kitco PM report, October 30, 2026).

So when two websites show different silver prices, check which series each one shows and when it was read before you assume one is wrong. The difference between spot and futures is called the basis, and it has its own explainer.

Silver fell to what was then its lowest level of the year on Friday, October 30, 2026 (source: Kitco AM report, October 30, 2026), nine months after its all-time high on January 29, 2026 (source: Silver Institute, World Silver Survey 2026). The slide from that peak through October has its own page, and named bank and analyst calls, with their bull, base and bear cases, are collected separately.

Key silver terms

A handful of words come up whenever silver is in the news: the fix, COMEX, the LBMA, EFP, contango, backwardation and the gold/silver ratio. Each one names a part of how silver is priced or traded, and once you know them a market report reads in one pass, from London's benchmark auction to the shape of the futures prices.

Contango and backwardation describe the same thing from two sides: the difference between the futures price and spot. When that difference flips from positive to negative, traders read it as a sign of tight physical supply, which is why silver reports mention it so often.

Ways to get silver exposure

Silver exposure comes in four main forms: buy physical bullion, buy shares of a silver exchange-traded fund (ETF), buy shares of silver mining companies, or trade a derivative such as COMEX futures or the XAGUSDT Perpetual. Only bullion puts metal in your hands. The others give you the price, each with its own costs, hours and minimum size.

At the late October 30, 2026 spot price of $49.015 an ounce, the smallest common unit of each route looked very different in size:

Bullion is the most direct route and the most expensive to run. Dealers sell coins and small bars above the spot price, you pay again to store and insure them, and when you sell, the dealer's buying price sits below spot. The large London bars are what banks and funds trade, and they are far beyond most private budgets.

An ETF trades like a share on a stock exchange and holds the metal for you. The iShares Silver Trust tracks the LBMA Silver Price and had 561,050,000 shares backed by 506,677,774.50 ounces on November 2, 2026, so each share stood for about 0.903 ounce (source: iShares Silver Trust). You buy it through a broker, in dollars, while the stock market is open.

Mining shares give you a company, and the company gives you silver plus everything else it carries: its costs, its debts and its management. They often carry the price of other metals too, since most silver comes out of the ground as a by-product of mining lead, zinc, copper and gold (source: Royal Society of Chemistry). A miner's shares can rise or fall on a bad quarter or a failed mine while silver itself is flat.

Derivatives give you the price alone. A standard COMEX contract covers 5,000 ounces, while CME's 100-ounce contract has traded around the clock since September 2026, and 2,387 of those contracts changed hands on the first weekend of round-the-clock trading (source: Kitco, September 14, 2026). BloFin lists no silver spot pair and no silver token, so on BloFin your route to silver is the XAGUSDT Perpetual, where the smallest order, 0.01 XAG, carries the price exposure of one-hundredth of an ounce.

Every way to invest in silver compares these routes side by side on cost, hours, leverage and ownership, and whether silver is a good investment sets out the case for and against holding it at all.

The live mark price, current funding rate and open orders are on the XAGUSDT Perpetual page.

How the XAG perpetual tracks silver

The XAGUSDT Perpetual is a USDT-margined contract on BloFin that follows the price of silver and has no expiry date, and it gives you no metal and no claim on any vault. BloFin values open positions at a mark price that follows an index price for silver, and that figure decides your unrealized profit and loss and when a position is liquidated.

Longs and shorts exchange a funding payment every four hours, at 12AM, 4AM, 8AM, 12PM, 4PM and 8PM UTC (source: BloFin XAG contract details).

Every contract term is set out in the guide to the XAG-USDT perpetual, and silver trading strategies shows how traders build positions on the contract.

Frequently asked questions

How many grams are in a troy ounce?

A troy ounce is 31.1034768 grams, about 9.7% heavier than the everyday ounce used for food (source: NIST conversion factors for precious metals; Troy weight on Wikipedia). Dollar prices for silver are quoted per troy ounce, so a silver price of $49 an ounce means $49 for 31.1 grams. A kilogram of silver holds about 32.15 troy ounces, which is the conversion to use when a bar is stamped in kilograms.

Where does most of the world's silver come from?

Most mined silver is a by-product. It is extracted from lead-zinc, copper, gold and copper-nickel ores as miners dig for those metals (source: Royal Society of Chemistry). In 2025, higher by-product output from copper mines in Peru was one of the main reasons global mine production rose 3% (source: Silver Institute, World Silver Survey 2026). Because so much output depends on other metals, silver supply often responds slowly when the silver price itself rises.

Is silver rarer than gold?

Silver is the more common of the two metals. In the Earth's crust, silver averages about 0.055 parts per million and gold about 0.0013 parts per million, which makes silver roughly 42 times as abundant (source: Royal Society of Chemistry; Royal Society of Chemistry, gold). Crustal abundance describes what sits in rock, while mine output describes what is dug up each year. In 2025 miners produced about 7.2 times more silver than gold by weight, on Silver Institute and World Gold Council counts. On both measures gold is the scarcer metal.

Does holding silver earn any income?

Silver pays no interest or dividend, so any return comes from the price alone. Every route also carries a holding cost: storage and insurance for bullion, and an annual fee for an ETF. On a perpetual, funding payments can cost or pay you every four hours, depending on which side of the market you hold. Over a long holding period those costs add up, which is why the price has to rise just for you to break even.

Is XAG a real currency?

XAG is listed in ISO 4217 beside national currencies, but no country issues it and no central bank manages it. Its code is one of the X codes the standard keeps for precious metals and other special units, alongside gold's XAU (source: ISO 4217 on Wikipedia). In practice, XAG is a unit of measure, one troy ounce of silver, used so that banks and trading systems can quote silver the same way they quote currency pairs.

Nothing in this article constitutes financial advice, and nothing in it is a recommendation to buy, sell or hold silver in any form. Silver can fall sharply in a single session, as it did on October 30, 2026, and because industry buys most of it, a slowdown in manufacturing can push the price down even when gold holds. Bullion carries dealer premiums and storage costs, and an ETF charges a fee. On the XAGUSDT Perpetual, funding is paid or charged every four hours, and high leverage can liquidate your whole margin on a move of a few percent. Past performance does not indicate future results.
