(Bloomberg) – BlackRock Inc. is currently grappling with an unexpected issue. Their prominent manager is a candidate for the Federal Reserve chair position, which complicates the future of their rapidly expanding active fixed income fund within the vast $14 trillion ETF sector.
Rick Rieder, an executive at BlackRock, has reportedly become a leading contender for President Trump’s nomination to lead the Federal Reserve, with an announcement anticipated next week. Prediction market platform Polymarket shows him as the frontrunner, boasting a 38% chance of being nominated.
This situation raises concerns about his flagship product, the iShares Flexible Income ETF (BINC), which has quickly gathered over $16 billion in assets in under three years. Its remarkable ascent on the active bond ETF ranking is, as Bloomberg Intelligence notes, partly due to Rieder’s influence. Todd Thorne, a senior analyst at Strategas, pointed out that while BlackRock has many skilled portfolio managers, Rieder is the public face of this fund.
“This represents ‘key man risk,’” Son mentioned on Bloomberg TV. “If you’re promoting this ETF that Rick manages and it’s performing incredibly well, losing him could change things drastically. I mean, I don’t know, but maybe people might reconsider their investments.”
BINC, while noteworthy, constitutes just a small portion of BlackRock’s total assets, which hit $14 trillion by the end of 2025. In contrast, the assets managed by Rieder in his fixed income division total around $2.7 trillion.
However, the striking growth of BINC makes it unique, and CEO Larry Fink has praised its performance in the recent earnings call, highlighting how ETFs have helped drive substantial inflows for BlackRock last year.
The strong returns are also boosting these inflows. The ETF capitalizes on a variety of fixed income sectors and locations, with significant investments in high-yield bonds and securitized products such as agency and commercial mortgage-backed securities. It boasts an average yield of around 5.7% and has seen over a 23% total return since its inception in May 2023, whereas the Bloomberg Composite Index returned about 13% in the same timeframe.
A BlackRock spokesperson opted not to provide a comment.
Rick Rieder has been with BlackRock since 2009, following a lengthy tenure at Lehman Brothers. Although he hasn’t worked with the Federal Reserve directly, he’s had a role in its Financial Markets Investor Advisory Committee and the Treasury Borrowing Advisory Committee, experiences that I think caught President Trump’s attention.
Rieder is recognized on Wall Street, but ETF industry expert Dave Nadig believes his potential move won’t trigger a mass withdrawal of funds similar to what happened after Bill Gross left PIMCO. When Gross departed in 2014, it resulted in a loss exceeding $100 billion for the firm.
“I don’t see Rick as the ‘big call guy’ that Bill Gross was, but he is more engaged with specific funds,” Nadig explained. He believes any outflows resulting from Rieder’s exit would likely redirect into other BlackRock offerings.
Nadig also noted that the context of a leader’s departure matters, suggesting that stepping up to the Federal Reserve would be a positive move for BlackRock, rather than leaving for a competing asset management firm.
Rieder is among several notable active managers reshaping the ETF landscape in recent years, moving away from the perception of ETFs as merely low-margin index trackers. For instance, strategist Tom Lee has attracted nearly $5 billion into his ETFs, while analyst Dan Ives has brought over $1 billion into his Wedbush AI Revolution ETF.
Thorne pointed out that the issue of “key man risk” will become increasingly important as more prominent managers enter the ETF space. A case in point is Cathie Wood of Ark Investment Management, whose tech-focused fund has thrived during the pandemic.
“What if Cathie decides to leave or something changes?” Son asked. “This is going to be a fascinating development over the next three decades as established players like these enter the ETF market and potentially lose key talent.”
