What it means
In the days before electronic screens, traders met in person on an exchange floor. The "ring" was a raised circular space, and members sat or stood around it to buy and sell.
Prices were agreed by shouting and by hand signals, and deals were struck on the spot. The system relied on trust and speed.
When a trader called out a price, another could accept it immediately, and the trade was binding. Clerks then recorded the details and passed them to the clearing process, which confirmed the trade and handled settlement.
On the London Metal Exchange, ring trading has a particular structure. Each metal is traded in short, fixed sessions, and the prices set during these sessions are used as official reference prices across the global metals industry.
Traders often work for banks and trading houses, buying and selling for clients as well as for their own accounts, and they must follow the exchange's rules on conduct and record keeping. Ring trading offers real advantages.
Prices form in the open, and traders can read the mood of the market from the volume and tone of the shouting. Face-to-face contact can also make it easier to build trust and to handle large or unusual trades.
It also has drawbacks. It is expensive to maintain a trading floor, and trading is limited to set hours and to people who can be physically present.
Electronic platforms are faster, cheaper and open to participants anywhere in the world, so most exchanges have replaced rings with screens. Even where the floor survives, it often runs alongside electronic trading, and prices from the two venues are closely linked.
Today the phrase is used mainly in the context of metals and in market history, and a finance professional reading about it should understand it as a traditional way to create prices.
In practice
Real-world examples.
Example
A copper dealer on a metals exchange calls out a bid for 25 tonnes during the short copper session. Another dealer accepts it by raising a hand, and clerks record the trade, which is later cleared. The whole exchange takes only a few seconds.
Example
A mining company wants a benchmark price for its output. Its treasurer uses the official price set in the exchange's ring session, which is published for the whole industry to see. Many physical supply contracts are priced as a premium or discount to that reference.
Example
A university lecturer explains price discovery to her students by describing how traders in a ring shout bids and offers. She contrasts it with a modern electronic order book, where the same process happens on screen. The class discusses what was gained and what was lost in the change.
Case study
Seen in the real world.
Brasswell Metals is a fictional trading firm used in an illustrative scenario. For many years it sent four dealers to sit in the exchange's ring and trade on behalf of customers.
As electronic trading grew, Brasswell found that many clients preferred to place orders on screens, where fees were lower and trades could be made at any time. The cost of keeping four dealers on the floor was about $1,200,000 a year, and their share of the firm's trades fell to less than a fifth. The firm reduced its ring team to two dealers and moved most of its business onto an electronic platform.
It kept a small presence in the ring to serve clients who needed help with large or complex trades. The illustrative case shows how a traditional method can survive alongside technology, even when it is no longer the main route to the market.
Watch out
Common mistakes.
- Assuming ring trading is the same as all open outcry. Ring trading is one form, in which dealers sit or stand around a ring, while other markets use pits.
- Thinking it is obsolete everywhere. A few markets still use it alongside electronic trading, although it is much less common. Where it survives, it is usually valued for its reference prices and for large, negotiated deals.
- Believing ring prices are only for ring members. Official prices from ring sessions are published and used widely. Producers, consumers and banks all refer to them in contracts.
Questions
People also ask.
Where is ring trading best known?
It is most associated with the London Metal Exchange, which has traded metals in rings for a long time.
Why did most exchanges stop using rings?
Electronic trading is cheaper, faster and available to participants worldwide. It also leaves a complete digital record of every order and trade.
How is a trade made in a ring?
A dealer calls out or signals a price, another dealer accepts, and the trade is recorded for clearing. The clearing house then guarantees that both sides meet their obligations.
