Welcome to ABC Score™ Lab


A New Chapter in Financial Transparency and Informed Decision-Making

Global PSSL CIC is entering a new phase, with ABC Score™ Lab (Assess–Balance–Calibrate) becoming our principal workstream. The Lab will develop and test practical approaches to strengthen transparency, governance and informed decision-making across the wider financial system.

As part of this transition, we have suspended the Global PSSL Secretariat, College of Advisors and existing working teams. The Global PSSL Principles remain in place, while ABC Score™ will continue to be maintained and developed.

We will be refreshing this website soon to reflect our new direction and the broader work of ABC Score Lab.

Update no. 2: Global PSSL in Washington, DC (ecosystem risks and learning points)

Global PSSL CIC has published its second follow-up paper from the October Washington, DC workshop, exploring ecosystem risks in securities lending and how they connect to the wider post-issuance phase of finance.

The paper draws on discussions with asset owners and market participants who offered thoughtful reflections on how different activities interact across the market. It is available [here].

A key learning point is that securities lending sits within a broader system that includes use of proceeds, short selling, collateral movements and derivatives. Recognising these links helps all parties identify practical opportunities to strengthen governance and support more resilient markets. Recent legal developments in the United States also show how post-issuance frameworks continue to evolve, creating further space for shared reflection.

The findings now contribute to the Beyond Issuance initiative and support the early development of ABC Score™, an impartial governance-focused tool designed to help market actors assess post-issuance behaviour in a constructive way.

About Global PSSL

Global Principles for Sustainable Securities Lending (Global PSSL) is the fundamental global mechanism for aligning securities lending with transparency and sustainable finance. It has been co-created by Dr Radek Stech, prominent asset owners, asset managers, sovereign wealth funds, banks, hedge funds other stakeholders committed to positive change since 2018. Global PSSL has received significant funding from the Economic and Social Research Council (ESRC), part of UK Research and Innovation, through the Sustainable Finance – Law – Stakeholders (SFLS) Network at Exeter Law School in addition to some financial assistance from some industry stakeholders. The ESRC grant request was designed based on earlier engagement with stakeholders shaping values-based banking, green bonds and sustainable project finance as well as continuous contact, research and discussions with staff from the World Bank (the official partner on the grant). In order to preserve its impartiality, the Global PSSL framework is based within its own independent community interest company.
