Broadridge Financial Solutions launches TAP to digitize Japan's TBA mortgage AOT processes

Broadridge brings TAP to Japan’s mortgage‑backed securities market

Digitalising AOT for TBA mortgage trading

Broadridge Financial Solutions is rolling out its Mortgage‑Backed Securities Trade Assignment Portal (TAP) in Japan after Nissay Asset Management implements the platform, marking the first adoption of the solution by a Japanese asset manager. The portal automates Assignment of Trade (AOT) processes for To‑Be‑Announced (TBA) mortgage‑backed securities, replacing email‑based workflows with instant creation and electronic signing of contract documents, simultaneous distribution of AOT letters to multiple recipients, and secure cloud storage of completed records.

The TAP provides real‑time tracking of AOT progress and delivers audit‑ready controls that cut manual touchpoints and shorten processing times, freeing traders to focus on planning, execution and analysis. Broadridge presents the deployment as a transformation from a traditionally manual, fragmented AOT cycle to a connected digital workflow that boosts automation and transparency across counterparties. Nissay positions the portal as preserving existing broker relationships and core operational practices while scaling TBA trading activity more efficiently.

Broadridge frames the Nissay rollout as an initial node in a broader network play where connected workflows across market participants reduce errors and settlement friction. The firm highlights that digitising AOTs is intended to improve client reporting and compliance oversight firmwide, supporting operational agility as trading volumes grow and regulatory expectations for recordkeeping and control tighten.

Why Nissay adopts the Trade Assignment Portal

Nissay Asset Management, part of Nippon Life Group and established in 1995, selects Broadridge’s TAP to relieve staff of administrative tasks and increase operational agility. The firm says the portal streamlines day‑to‑day AOT activities while maintaining established processes, enabling it to reallocate resources toward higher‑value investor initiatives and client outcomes.

Regional rollout and industry context

The deployment arrives as Japan’s asset management industry faces pressure to reduce routine, manual tasks and redirect resources to innovation and client servicing. Broadridge is expanding digital AOT capabilities across Asia, aiming to build a wider network that improves settlement efficiency, reduces error rates and supports scalable, compliant operations for institutional market participants.
