Senators Bill Cassidy and Tim Kaine introduced a plan to address Social Security's looming funding shortfall by creating a $1.5 trillion investment fund focused on stocks and risk assets. The proposal aims to maintain current benefits without tax hikes or cuts, despite projections that the Social Security trust fund will be depleted by 2032, leading to a 22% reduction in benefits unless changes occur, according to fortune.com.
The Cassidy-Kaine plan involves the federal government borrowing $1.5 trillion to invest in the stock market, targeting higher returns than Treasury bonds over a 75-year horizon. Additionally, the plan calls for $25.1 trillion in borrowing to cover the gap between Social Security's revenue and benefits during this period. The investment fund's returns would then be used to repay the $26.6 trillion in total new debt, as outlined by fortune.com.
This approach is notable because it avoids direct cuts to benefits or tax increases, relying instead on market gains and substantial borrowing. However, simulations by Boston College’s Center for Retirement Research suggest the plan is unlikely to succeed, highlighting the risks of depending on stock market returns to fund Social Security. The proposal contrasts with traditional methods of addressing the shortfall, which often involve benefit reductions or tax changes, per fortune.com.
The Social Security trust fund’s projected insolvency by 2032 underscores the urgency of reform, with the Cassidy-Kaine plan representing one of the most significant federal borrowing proposals in recent history. The senators’ proposal was detailed in June 2026, marking a critical moment in the debate over the program’s sustainability, according to fortune.com.
