Bloomberg has completed its first fully automated Japanese Government Bond (JGB) Market-on-Close transaction following the launch of a new trading workflow. Built around BB3P (Hikene Trading), the designated Market-on-Close reference rate for JGBs, the workflow streamlines execution, reduces tracking error, and delivers greater certainty by executing trades at a predetermined market close.
Available as part of Bloomberg Electronic Markets, the workflow combines the Bid/Offer List Trading functionality with Rule Builder, Bloomberg’s trade automation tool, enabling clients to define execution criteria and automate order routing based on predefined conditions within an integrated order and execution management workflow, through TSOX.
“The ability to combine Market-on-Close execution with rule-based automation is a significant step forward for the JGB markets. By accelerating time to market and enabling more systematic execution at the BB3P market reference, this workflow will help minimize transaction costs, reduce manual intervention, and deliver more consistent, optimized outcomes for investors, particularly during high-volume periods. It is an exciting development for one of the highest volume bond markets in Asia, and we were pleased to collaborate with Bloomberg on introducing the protocol.”
-Yudhveer Chaudhry, Head of Emerging Markets, FX, Commodities & Digital Assets at BlackRock
