London, 3 November 2025 – Propellant Digital (“Propellant”), a leading technology provider in fixed income data analytics, has appointed Elizabeth Brooks Callaghan as Senior Advisor, Business Development and Strategy. This appointment further strengthens Propellant’s leadership team and reflects the company’s rapid growth across global fixed income markets.
Elizabeth’s deep expertise in senior industry collaboration, regulatory strategy, and market structure will help Propellant accelerate its momentum and expand its global reach. This announcement comes shortly after the launch of Propellant’s Global Fixed Income Technology Solution, which enables firms to connect to multi-jurisdictional transparency venues through a single, unified platform.
In her new role, Elizabeth will advise on senior stakeholder engagement and strategic growth, working closely with the team to support Propellant’s focus on transparency, seamless market data consolidation, and advanced technology solutions.
Before joining Propellant, she served as Chief Strategy Officer of Etrading Software and as Senior Director of the International Capital Market Association (ICMA), where she helped design the EU’s bond transparency framework under MiFID II.

Elizabeth Brooks Callaghan, Senior Advisor, Business Development and Strategy, stated:
“After taking a career break from the end of January until now, I’m thrilled to be joining Propellant, where I’ll help equip market participants today—not tomorrow—with the data-driven tools they need to navigate and prepare for the upcoming transparency regimes coming into effect in December 2025 in the UK and March 2026 in the EU, and beyond. Propellant’s global suite of products supports firms worldwide in meeting evolving regulatory requirements and enhancing transparency across markets.
