National Pension Service of Korea (NPS), thought to be the world’s third largest pension fund, has expanded its agreement with BNY Mellon to include middle office, accounting and risk solutions, delivered through BNY Mellon’s OMNI platform. NPS appointed BNY Mellon in 2018 as its global custodian for its fixed income portfolios, which were recently onboarded. State Street provides middle- and back-office services for NPS’ global equities portfolios.
