Voice Brokered Market

A voice brokered market is a trading venue where prices are negotiated verbally or in text chat between dealers and brokers, without the intermediation of an automated matching engine. A human broker—employed by a brokerage firm—takes calls from multiple dealers simultaneously, relays their prices and orders, and negotiates terms until a trade is struck. This model persists in less liquid markets, large block trades, and certain asset classes where information and relationship are more valuable than split-second execution speed.

The broker as information hub

In a voice brokered market, the broker is not a dealer—the broker does not put capital at risk and takes the opposite side of trades. Instead, the broker is an information aggregator and negotiator. A dealer at Bank A calls his broker at a voice brokerage firm (say, Tullett Prebon or ICAP) and says, “I’m looking to buy 100 million euros—what are the axe prices?” The broker, knowing his network of clients, might have heard earlier from dealers at Bank B, Bank C, and Bank D that they are offering euros. The broker relays: “I have 50 million offered at 1.0960, and I can ask for more.”

The dealer at Bank A says, “I’ll take 50 at 1.0960.” The broker calls Bank B’s dealer, confirms the trade, and records it. The two counterparties do not speak directly; the broker is the middleman. This separation protects both dealers from signalling their identities too early and allows the broker to warehouse information: which institutions are looking to buy, which are looking to sell, and at what prices.

The broker’s revenue is a commission per trade, usually a small basis-point fee (0.1–0.5 basis points per trade, plus sometimes a fixed fee per deal). Because the broker moves high volume—handling hundreds or thousands of trades per day across a specialised market segment—this commission adds up.

Speed vs. information richness

The defining trade-off of voice broking is speed for depth. On an electronic broking system like EBS, a dealer hits a two-way price in milliseconds and the trade is done. On a voice market, the entire process—finding counterparties, negotiating terms, confirming details—takes five minutes to an hour. This is why electronic venues have cannibalised the most liquid, standardised segments of global markets: major FX pairs, liquid government bonds, large-cap equities. For these, speed dominates.

But voice broking persists in illiquid and bespoke markets. Consider emerging-market bonds, esoteric derivatives, or large block trades in less-liquid equities. On an electronic system, a dealer trying to sell 100 million dollars of an emerging-market government bond might see a two-way quote of bid 99.50, ask 99.52. The spread is tight, but it reflects the dealer’s real inventory and risk appetite—often pessimistic if the market is stressed. A voice broker, by contrast, can phone a dozen larger investors (pension funds, insurance companies) and say, “I have a real seller of 100 million EM bonds. What’s your order?” Several may respond: “I’m interested at 99.45, and I can take 50 million.” After negotiation, the dealer and investors might agree at 99.48 on a 60 million size. The voice broker has found a better price than the electronic bid—and has arranged a trade that would not have happened on a pure electronic system because the demand was not continuously posted.

The human element and relationship value

Voice broking is predicated on trust and relationship. A broker who has worked with the same twenty-five dealers for ten years knows their trading styles, their risk appetites, and their likely interest in particular instruments. When a dealer says, “I want to buy high-beta tech exposure and I’m patient,” the broker mentally flags tech-focused salespeople at hedge funds and asset managers. When another dealer says, “I’ve got a forced seller of illiquid corporate bonds,” the broker knows which insurance companies and value investors might be interested.

This relationship capital is why voice brokers can charge commissions at all, despite electronic venues offering near-zero spreads. The broker is selling information, connectivity, and the ability to move large, illiquid inventory that would tie up capital on an electronic system.

Chat and electronic voice broking

Modern voice broking has partially automated itself. Rather than phoning dealers one by one, brokers now use dedicated chat platforms (sometimes called “messaging brokers”) where a broker types or uses voice to negotiate. Systems like Bloomberg chat or dedicated dealer platforms allow a broker to broadcast an indication (“I have a seller of 500M EM sovereigns”) to a group of dealers simultaneously, then manage the responses and negotiations in a half-electronic, half-manual process.

These platforms preserve the information richness and relationship element of voice broking while adding some speed. A dealer in Tokyo can message a broker in London without a time-zone delay, and the broker can manage conversations with multiple parties in parallel. But it is still slower than a fully electronic exchange, because human judgment, reputation, and negotiation remain central.

Regulation and manipulation

Voice broking has historically been opaque to regulators. Unlike electronic exchanges, where every trade is time-stamped and recorded automatically, voice broking relied on brokers’ records and traders’ written confirmations. This opacity created opportunities for manipulation. During the LIBOR scandal (mid-2000s to early 2010s), traders at major banks allegedly colluded with brokers and each other to move benchmark interest rates through coordinated voice-brokered trades and rate submissions.

Since then, regulators have imposed recording requirements: voice brokers and dealers must record telephone conversations, and chat-based broking platforms create electronic audit trails. The UK Financial Conduct Authority and the US SEC have also imposed “voice broker” regulations that require brokers to be registered, to have compliance controls, and to document their communications. This has reduced—though not eliminated—the potential for collusion.

Where voice broking endures

Voice broking remains dominant in specific markets:

• Large block trades in equities, where a hedge fund or asset manager wants to unload 200M USD of a stock without shocking the market, and enlists a voice broker to find a counterparty willing to absorb the block at a negotiated price.
• Illiquid fixed income: emerging-market bonds, high-yield credit in stressed periods, structured products, and derivatives where electronic liquidity is sparse and negotiation is essential.
• Forex derivatives: options and exotic forwards where there is no standardised electronic market, and dealers must negotiate pricing and terms with each other via brokers.
• Equities in smaller or less-developed markets, where electronic exchange infrastructure is nascent and dealer-to-dealer voice trading is still the backbone.
