Block Trading Explained: Avoiding Slippage with Privately Negotiated Trades

·

A block trade is a privately negotiated purchase or sale of large blocks of assets settled over the counter. Block trades enable traders to buy or sell vast quantities of shares, derivatives, bonds, or cryptocurrencies without affecting an asset’s market price due to slippage.

This article explores block trading, its benefits, and how traders use it to execute large positions discreetly and efficiently.

What Is Block Trading?

Block trading is an over-the-counter (OTC) method where high-net-worth participants trade large asset volumes without causing market price fluctuations. Typically used by institutional investors, hedge funds, or wealthy individuals, block trades are executed privately to avoid public order books.

How Block Trading Works

  1. Request-for-Quote (RFQ): Traders submit an RFQ to a block trading platform (often a broker-dealer).
  2. Market Maker Quotes: The platform splits the trade into smaller blocks, and market makers provide execution prices.
  3. OTC Execution: If accepted, the trade settles OTC, bypassing public order books and ensuring price certainty.
