Question · Q3 2025
Simon Clinch asked about the mix of credit volumes, the reasons and sustainability behind the surge in block trade sizes and the shrinking of smaller trade sizes, and whether the squeezing of the dealer-to-client portion of the market is a persistent trend or cyclical.
Answer
CEO Chris Concannon explained that smaller trades are driven by portfolio trading (large notionally, small line items) and the growth of SMA accounts, where automation tools are heavily used. He expects smaller tickets to continue growing, partly due to larger trades being broken down by credit algos. For larger block trades, he attributed their growth to historically low volatility and tight spreads, making blocks an attractive risk exchange tool for dealers and clients. He anticipates that with a return to normal volatility, larger blocks will also be broken into smaller tickets, aligning with electronic transformation trends.
