What it means
Most bonds do not trade on an exchange the way shares do. A single company may have a dozen different bonds outstanding, each with its own maturity and coupon, and many of them go days without a single trade.
That fragmentation is why the market relies on intermediaries who can find the other side of a trade rather than on a central order book. There are two broad models.
A pure broker acts as an agent, matching a buyer with a seller and charging a commission without ever owning the bond, while a dealer or broker-dealer takes the bond onto its own book and resells it, earning the spread between its buying and selling prices. The distinction matters because a dealer carries price risk and an agent does not.
A third variety, the inter-dealer broker, sits between the large dealing banks themselves. Their role is to let one bank sell a large position without revealing its identity to competitors, which reduces the risk that the market moves against the seller before the trade is done.
Anonymity is the product being sold. For a corporate treasurer or a finance director, the practical question is how the broker is paid.
An explicit commission is transparent and easy to compare, while compensation embedded in the price is harder to see and can be larger than it looks. Asking for the commission and the price separately is the single most useful habit when dealing in bonds.
Electronic platforms have taken over much of the routine business, particularly in government bonds and large, frequently traded corporate issues. Human brokers remain important for illiquid bonds, unusual sizes and stressed markets, precisely the situations where a screen shows no meaningful price.
The role has narrowed rather than disappeared.
In practice
Real-world examples.
Example
A corporate treasurer wants to sell $5 million of a thinly traded utility bond. Her broker spends two days finding a single insurance buyer willing to take the whole block, avoiding the price damage of breaking it into small pieces.
Example
A pension fund uses an inter-dealer broker to exit a large government bond position without revealing its identity. The anonymity keeps other dealers from marking prices down in anticipation of the sale.
Example
A family office compares two quotes on the same bond and finds one broker charging an explicit $2,000 commission and another quoting a price 0.4% worse with no visible fee. On a $1 million trade the second is the more expensive route at $4,000 of embedded cost.
Formula
Calculation
Broker compensation from a spread = (Selling price per bond - Buying price per bond) x Number of bonds, where bond prices are quoted as a percentage of face value.
A broker-dealer is asked to help an insurance company sell $2,000,000 of face value in a corporate bond. Since each bond has a face value of $1,000, that is 2,000 bonds. The dealer buys the position from the insurer at a price of 98.50 and later sells it to a pension fund at 99.25.
Buying price per bond = 98.50% x $1,000 = $985.00
Selling price per bond = 99.25% x $1,000 = $992.50
Spread per bond = $992.50 - $985.00 = $7.50
Total compensation = 2,000 x $7.50 = $15,000
As a percentage of face value, that is 0.75% of $2,000,000, which equals $15,000 and confirms the arithmetic. Had the same trade been done on an agency basis at a stated commission of $1.50 per $1,000 of face value, the broker would have earned 2,000 x $1.50 = $3,000, with the price difference passing to the client instead.Case study
Seen in the real world.
Brightwater Credit Partners is a fictional asset manager used purely to illustrate how bond broking compensation works. Its dealing desk placed all of its corporate bond trades through a single relationship broker who quoted net prices, meaning no commission line ever appeared on the confirmations. The head of operations liked the simplicity and assumed the firm was paying nothing for execution.
During an annual review, an analyst compared the firm's execution prices with independent pricing data on the day of each trade. Across roughly $40,000,000 of turnover in a year, the average difference against the reference price was about 0.35%, implying an embedded cost of around $140,000 that had never appeared as a fee anywhere in the accounts.
In this illustrative case Brightwater did not conclude that the broker had behaved improperly, since net pricing is a normal market convention. It did change its policy to require at least two competing quotes on any trade above $1,000,000 and to record the reference price at the time of dealing. The measured execution cost fell by roughly a third in the following year.
Watch out
Common mistakes.
- Assuming a trade with no visible commission is free. Compensation is often embedded in the price, and an embedded cost can easily exceed a stated commission on the same trade.
- Treating brokers and dealers as identical. A broker acts as an agent and never owns the bond, while a dealer buys it onto its own book and carries the price risk.
- Judging a broker only on price for a single trade. The ability to find a buyer for an illiquid position at a fair level is worth far more over time than a few cents on an easy trade.
Questions
People also ask.
How do I compare two bond quotes properly?
Ask each counterparty to state the price and any commission separately, and compare both against an independent reference price for that bond on the same day.
Do I still need a bond broker if electronic platforms exist?
For liquid government bonds and standard sizes, often not, but for unusual bonds, very large blocks or unsettled markets a broker still adds real value.
What is an inter-dealer broker?
An intermediary that arranges trades between the dealing banks themselves, with anonymity as the main service so that a large seller does not move the market against itself.
