Paul Greff's Blueprint for Transforming a $130B Ohio Public Employees Retirement System Pension Fund

Angelo Calvello, host of Institutional Edge, interviews Paul Greff, Chief Investment Officer of Ohio Public Employees Retirement System (OPERS) since 2018, about his comprehensive transformation of the $130 billion pension fund. Greff describes building a "failure-tolerant" culture of open innovation that encourages intelligent risk-taking, breaks down silos, and surfaces problems early. From 2018 to 2023, he restructured the portfolio by unwinding the 10% hedge fund allocation, moving from 35% to 55% internally managed assets, achieving a measurable reduction of fees, and consolidating multiple risk systems into one unified platform accessible to all staff. Paul Greff is the Chief Investment Officer at Ohio Public Employees Retirement System (OPERS), a position he has held since 2018. Before becoming CIO, Paul served as Deputy CIO for two years and spent seven years as Head of Global Bonds at OPERS. Prior to joining OPERS, he was Senior Managing Director and Head of Global Fixed Income at State Street Global Advisors. With 36 years of institutional investing experience across public and private markets, Paul brings deep expertise in derivatives, fixed income, and multi-asset class portfolio management. He is a CFA charterholder.
