Buy-Side Traders Favor Separate OMS and EMS Over Integrated Solutions

Order management systems (OMS) and execution management systems (EMS) remain the backbone of buy-side trading infrastructure, enabling firms to manage orders, execute trades, and analyze performance with precision. Despite technological advancements blurring the lines between the two, a recent North American study by Crisil Coalition Greenwich reveals a clear preference among buy-side traders for separate OMS and EMS platforms over integrated solutions.

Specialized systems offer greater control, flexibility, and customization—qualities that outweigh the convenience and potential cost savings of consolidated platforms. "The benefits of specialized systems seem to outweigh these advantages for now," says Jesse Forster, Senior Analyst at Crisil Coalition Greenwich. The demand for tailored solutions underscores the buy-side's prioritization of performance over simplicity.
