<p>A liquidity provider is an institution that supplies continuous buy and sell quotes to brokers, enabling them to execute client trades without delay. In the foreign‑exchange market, these entities are typically banks, non‑bank financial firms, or specialized liquidity aggregators that connect to the <a href="/NewSite/encyclopedia/interbank-market/" class="ency-link">interbank market</a> and offer competitive pricing.</p>

<h2>How It Works</h2>
<p>When a trader places an order through a broker, the broker routes the request to one or more liquidity providers. The provider returns a bid (price to buy) and an ask (price to sell) based on current market conditions. The broker then selects the best available quote, adds its markup or commission, and executes the trade on behalf of the client.</p>
<ul>
<li><strong>Quote aggregation:</strong> Providers stream real‑time prices from multiple sources.</li>
<li><strong>Order matching:</strong> The broker matches the client order to the provider’s quote.</li>
<li><strong>Execution:</strong> The trade is filled instantly, often with minimal slippage.</li>
<li><strong>Risk management:</strong> Providers hedge their exposure in the interbank market to maintain stable pricing.</li>
</ul>

<h2>Why It Matters</h2>
<p>Liquidity providers are essential for tight spreads, fast execution, and reliable pricing in forex trading. Without them, brokers would struggle to offer competitive rates, leading to higher costs and increased slippage for traders.</p>
<p>For example, a retail trader buying EUR/USD through an <a href="/NewSite/encyclopedia/stp-broker/" class="ency-link">STP broker</a> sees a spread of 0.8 pips because the broker accesses quotes from several top‑tier liquidity providers. If those providers withdrew, the broker would have to widen the spread significantly or risk being unable to fill the order, directly impacting the trader’s profitability.</p>
