In financial markets, “market makers” may sound like magicians behind the scenes, but their role is far from smoke and mirrors. These participants provide liquidity, match buyers and sellers, and help create a smoother trading experience. Yet, their influence on best execution—the ability to get the best terms on trades—can sometimes feel complex to understand. In this blog, let’s dive into how market makers operate and how they impact best execution for investors. Are market makers driving order execution outcomes more than expected?

A market maker is essentially a financial firm or individual who actively buys and sells securities, often to support continuous trading. Imagine a store that always has stock and can instantly meet customer demand; that’s what market makers do for securities.
They hold inventories of stocks, currencies, or other assets and quote both “bid” (buy) and “ask” (sell) prices. By doing so, they create a marketplace where trades can happen smoothly and more frequently.
Without market makers, the buying and selling of securities would be much slower, often resulting in greater price fluctuations. Their constant presence on both sides of the trade ensures that there’s someone willing to buy when you want to sell, or vice versa.
Market makers reduce the likelihood of gaps in trading activity, stabilizing markets by ensuring trades happen more easily and with lower costs. This stability is essential for best execution because it allows trades to go through without major delays or price slippage.
Market makers have a direct hand in the pricing of trades. Since they offer both buying and selling prices, they control the “spread”—the difference between the bid and ask prices. The size of this spread impacts how favorable your trade terms are. A smaller spread means less cost to the trader, while a larger spread can make trades pricier.
So, why does the spread vary? It often depends on the asset’s liquidity and the level of market activity. For highly liquid assets, such as major stocks or popular currency pairs, spreads are typically narrower.
With less-liquid assets, however, market makers might widen the spread to cover the risk of holding that asset. This spread difference can make achieving best execution more challenging when trading in low-liquidity markets, as investors may end up paying a little extra to complete their trades.
To get the best possible trade terms, it’s useful to monitor the spreads offered by different market makers. Working with brokers who offer competitive spreads or trading during times of high market activity (such as during overlapping trading hours for currencies) can help you get a better deal. It’s a good idea to consult a financial expert for guidance on timing trades to optimize pricing and minimize costs.
Liquidity is the lifeblood of any active market. Market makers are essentially the “liquidity providers” who keep this lifeblood flowing by holding and trading large quantities of assets. By constantly buying and selling, they ensure there’s always a counterparty available, reducing the time and cost involved in executing trades.
Consider a market with low liquidity, like a rural grocery store that only stocks items when people ask for them. You may need to wait for that item, or you might pay a higher price because of low supply. Market makers prevent this issue in financial markets by holding large quantities of assets, making trades faster and keeping prices fairer.
For investors, having adequate liquidity is crucial for best execution. High liquidity means lower spreads, faster trades, and a greater likelihood of getting the desired price. Working with a reliable broker who connects you to top market makers can improve your trade outcomes, particularly when dealing with assets that aren’t traded frequently.
Always check if your broker is connected to reputable market makers and consider consulting a financial advisor to understand the best liquidity options for your investment strategy.
Market makers may seem like invisible players in the trading game, but their influence on best execution is anything but hidden. They create the trading environment, setting prices, offering liquidity, and sometimes introducing challenges. Understanding how they work, why they set prices as they do, and how to leverage their role can improve your trading results.
