NYC Reassessing BlackRock Pension Mandate; Final Call Expected Under Mamdani
NYC may rebid BlackRock’s $42.3B pension mandate over climate-risk concerns, with the decision set to be handled under Mayor-elect Zohran Mamdani.
New York City Comptroller Brad Lander has called for a major review of BlackRock’s role in managing retirement money for city workers, setting up an early test for Mayor-elect Zohran Mamdani. In a memo sent November 25 to pension trustees, Lander said the firm has stepped back from holding U.S. companies accountable for climate-related financial risks and may no longer align with the funds’ long-term interests.
BlackRock oversees about $42.3 billion in assets for the city’s retirement systems, which serve roughly 800,000 current and former municipal employees. The firm is the largest external manager in the portfolio, giving it significant influence over how climate exposure, emission regulation, and long-range energy risk translate into investment decisions.
Lander pointed to BlackRock’s recent policy change that limits how it engages with corporate leaders on issues like emissions disclosure. The firm told federal officials earlier this year that it would avoid urging companies to adjust climate policies — a shift that followed pressure from Republican critics who argued big asset managers were interfering with business strategy. Lander called the approach shortsighted and warned that failing to assess climate-related financial threats undermines fiduciary responsibility.
His recommendation does not cut ties outright. Instead, he wants pension trustees to open the contract to competition for U.S. equity mandates, while keeping BlackRock in place for international index strategies. He also advised maintaining $8 billion in index investments run by State Street and dropping managers such as Fidelity and PanAgora, which he said show the same reluctance to address material climate risks.
The timing places the decision squarely in front of Mamdani once he takes office on January 1. New appointees from his administration will sit on or influence the boards that vote on pension contracts, meaning the incoming mayor will help decide how one of the nation’s largest public retirement systems responds to climate-risk concerns. For Mamdani — who campaigned on financial fairness and accountability — the pension issue is becoming one of the first major questions of his term.
The debate also reflects a broader national split. Several Republican-led states have withdrawn assets from BlackRock, arguing the company has been too aggressive on environmental oversight. New York’s potential rebid would make it one of the first large Democratic-aligned systems to act for the opposite reason — saying that not addressing climate exposure puts workers’ savings at risk.
Environmental finance advocates say the outcome will signal how the city plans to defend pension stability in a changing market. They argue that climate-driven disruptions are not political speculation but real investment risks with long time horizons — exactly the period pension funds must manage.
Decisions on the BlackRock contract are expected after the administration changes hands, making this one of the earliest financial choices that will define how Mamdani governs a system responsible for the retirement security of hundreds of thousands of New Yorkers.
