In 2025, Social Security’s combined trust funds earned a 2.6% annual effective interest rate, per the Social Security Administration. That same year, the S&P 500 returned roughly 16%, and a standard 60/40 portfolio returned nearly 15%, per the Morningstar US Moderate Target Allocation Index. That gap is the entire argument BlackRock (NYSE:BLK) CEO Larry Fink is making.

Why the Return Is So Low by Design

The 2.6% is the result of legal design. Social Security’s trust funds must invest exclusively in US Treasury securities, and the program runs largely pay-as-you-go: today’s payroll taxes fund today’s benefits, with the trust funds holding the surplus in government bonds. The result is stability and predictability, with almost no participation in economic growth. Since 1989, a dollar in the US stock market has grown more than 15 times the value of a dollar tied to median wages.

What Fink Actually Proposed

In his 2026 Annual Chairman’s Letter to Investors, released March 23, Fink, who runs the world’s largest asset manager with $14 trillion under management, made his most direct case yet. “Social Security provides stability, but it doesn’t allow most Americans to build wealth in a way that grows with their country,” he wrote. “In effect, workers lend money to the government and receive defined benefits in return… What it doesn’t do is let people grow their benefits along with the broader economy.”

He was clear about what he is not saying. He refused the word “privatization,” is not proposing to move all of Social Security into stocks, and is not touching guaranteed benefits, calling the program “one of the most effective poverty-prevention programs in history.” Fink is amplifying a bipartisan proposal from Senators Bill Cassidy (R-Louisiana) and Tim Kaine (D-Virginia). Their plan creates a new $1.5 trillion investment fund that supplements the existing trust funds. The current funds stay intact and keep buying Treasuries. The new fund, modeled on the federal Thrift Savings Plan, invests in a diversified mix of stocks and bonds, seeded by $1.5 trillion the Treasury borrows. It gets 75 years to grow, then repays the Treasury and supplements payroll-tax revenue. No current or near-retirement beneficiary sees any change.

Why the Urgency Is Real

The Congressional Budget Office’s February 2026 projection has the trust fund depleting in 2032, two years sooner than previously expected, triggering automatic benefit cuts of at least 20-23%. More than 70 million Americans rely on Social Security, and the Bipartisan Policy Center estimates a $25 trillion shortfall over 75 years. Congress has not meaningfully touched the program since 1983. As the Bipartisan Policy Center’s Emerson Sprick put it, the stakes are higher now than at that last major revision.

The Pushback

Alicia Munnell of Boston College’s Center for Retirement Research called the plan “a huge and risky financial maneuver with very little payoff,” arguing that returns are capped by borrowing costs and the plan diverts attention from the real revenue-benefit imbalance. Gopi Shah Goda of the Brookings Institution warned that borrowing $1.5 trillion would likely raise interest rates by lifting Treasury supply and pushing yields up. Sita Slavov of George Mason University objects to borrowing rather than raising payroll taxes, which directly support the program.

The Conflict of Interest

Fink runs the firm that would likely benefit. If government retirement money flowed into diversified stocks and bonds, asset managers would earn fees, and BlackRock, which already runs the Thrift Savings Plan and numerous state pensions, is the natural beneficiary. Fink did not acknowledge this in his letter. The conflict is real, though it does not automatically invalidate the argument, and BlackRock’s TSP management has been broadly successful.

The Bull Case Isn’t Frivolous

Fink points to working models: Australia’s superannuation system, which produced one of the world’s highest retirement savings rates; Japan’s NISA program, which added 10 million new investors and helped lift the Nikkei from 28,000 to 50,000; roughly six million US state and local employees already relying on diversified public pensions that have generally outperformed Social Security’s Treasury-only approach; and the federal Thrift Savings Plan itself, which has managed diversified money for federal workers for decades.

What You Should Actually Do

The 2032 deadline is real, and a 20-23% automatic cut is the baseline if Congress does nothing. Maximize your own savings now. In 2026, the 401(k) contribution limit is $23,500 ($31,000 for those 50 and up with catch-up).

Delaying Social Security is the most risk-free “investment” a retiree has: benefits grow about 8% for each year you wait past full retirement age. Build the emergency fund first. BlackRock’s own research shows workers with dedicated emergency savings are more than 70% more likely to contribute to their retirement plans.

Congress last restructured Social Security in 1983. The 2032 deadline may be the next forcing function, and whether the answer is Fink’s endorsed plan or something else, doing nothing is not an option. That debate will not resolve before 2032. Your own retirement planning cannot wait for that.
