Charles River and Neptune Networks Announce Strategic Collaboration to Provide Fixed Income Inventory Data to Buy-side

May 21, 2019

Boston — May 21, 2019 — Charles River Development, a State Street Company, and Neptune Networks Ltd. (Neptune), today announced a strategic collaboration that will provide buy-side clients of Charles River’s Order and Execution Management System (OEMS) with aggregated, real-time fixed income axes and inventory. Neptune provides technology solutions that enable real-time connectivity and deliver high-quality bond market data from sell-side banks to buy-side clients.

The collaboration is the latest addition to Charles River’s growing ecosystem of global liquidity venues, data, analytics, third party apps, and benchmark providers. Buy-side firms can configure and scale the Charles River platform to optimally support their asset mix, investment process and execution priorities.

“Collaborating with Neptune underscores Charles River’s commitment to offering our clients the most diverse and comprehensive platform available for managing their fixed income products and portfolios,” said John Plansky, CEO Charles River. “Neptune’s innovative approach to standardizing massive volumes of unstructured data and aggregating liquidity across multiple dealers enables our clients to make faster and more informed trading decisions in highly fragmented and illiquid fixed income markets.”

Since its 2016 launch, Neptune has grown rapidly with 28 dealers on the platform, over USD210B of gross notional and more than 60,000 axe/inventory items updated in real time across 30,000 individual bonds daily.

In addition to Investment Grade, High Yield, Emerging Markets and Rates, Neptune now quotes MBS and Munis, and has recently added bilateral messaging to further digitize the fixed income trading lifecycle. By providing a facility for direct exchange of axe and inventory information, Neptune enables greater transparency and trading efficiencies between bond dealers and investment firms.

“Connectivity to the Charles River OEMS will benefit our mutual buy-side clients by automating time consuming price discovery and liquidity aggregation,” said Byron Cooper-Fogarty, Neptune’s Head of Sales. “Portfolio managers can quickly target axes and inventory of interest, enabling faster decision making and fewer missed trading opportunities. The inventory data captured in the Charles River OEMS also aids clients in demonstrating and documenting MiFID II-mandated best execution requirements.”
