ICMM board member Lee Tate recently attended the 2026 Pension Research Council Symposium, hosted at the Wharton School of the University of Pennsylvania. The annual symposium brings together leading researchers, economists, and policy experts to examine pressing challenges at the intersection of public finance and retirement security.
This year’s symposium — titled Public Debt and Retirement Security — featured thirteen presentations spanning fiscal policy, pension investment strategy, Social Security reform, sovereign debt politics, and intergenerational financial risk. Tate’s participation reflects ICMM’s ongoing commitment to staying at the forefront of research and policy conversations that shape financial wellbeing for low- to moderate-income individuals and families.
Symposium Overview
The 2026 Pension Research Council Symposium examined the growing relationship between public debt, demographic change, and retirement security in the United States and globally. Across the presentations, speakers explored how aging populations, rising healthcare and retirement costs, persistent federal deficits, and growing interest payments are reshaping the long-term fiscal outlook. Several presenters also discussed how these pressures are influencing pension systems, government policy choices, financial markets, and household retirement planning. Although the presenters approached the topic from different academic and policy perspectives, several broad themes emerged consistently throughout the symposium. Population aging was widely identified as one of the primary drivers of future fiscal pressure, particularly through rising Social Security and Medicare expenditures. Many presenters also emphasized that high and growing debt levels can reduce economic flexibility, increase vulnerability to future crises, and complicate long-term retirement security planning. At the same time, there was broad recognition that retirement systems are deeply interconnected with larger political, economic, and demographic trends. Speakers emphasized that challenges facing retirement systems are deeply interconnected with broader political, economic, and demographic trends — and that earlier, more gradual policy adjustments tend to produce better outcomes than delayed responses to structural imbalances.
The following summaries provide a brief overview of five presentations selected from the symposium (There were 13 presentations. They can be viewed on YouTube: 2026 Symposium: Public Debt and Retirement Security).
Selected Presentations
Global Pension Asset Allocations and Debt Markets
Karen Lewis examined how rising public debt levels and changing financial conditions are influencing global pension investment strategies and capital markets. Her presentation focused on the important role pension systems play as large institutional investors, particularly in government bond markets. She discussed how pension funds are increasingly operating in an environment shaped by higher debt levels, uncertain long-term growth, changing interest-rate conditions, and market volatility. The presentation also explored how pension asset allocations have evolved internationally, including shifts between equities, fixed income investments, and alternative assets as funds attempt to balance long-term returns with funding stability and risk management.
- Government bond markets remain central to pension investment strategies
- Pension systems are increasingly influenced by rising global debt levels
- Pension funds are balancing return expectations against growing market uncertainty
- Asset allocation is growing more complex in a higher-debt environment
- Long-term fiscal conditions directly affect pension funding stability and investment returns
Population Aging and the Long-Term Federal Debt Outlook
Karen Dynan discussed how population aging is contributing to the long-term rise in federal debt and creating growing fiscal pressures for the United States. She noted that federal debt is already roughly the size of the US economy and is projected to continue increasing substantially in coming decades. The presentation emphasized that rising Social Security and Medicare spending, combined with a declining ratio of workers to retirees and growing interest costs on federal debt, are key drivers of projected deficits. Dynan also reviewed several factors that could potentially improve the fiscal outlook—such as stronger productivity growth, artificial intelligence, lower interest rates, or inflation—but concluded that none of these factors alone are likely to fully offset the nation’s long-term structural fiscal imbalance.
- Population aging is a major contributor to rising federal debt
- Social Security and Medicare spending are projected to grow significantly
- Interest payments are consuming a larger share of the federal budget
- Economic growth and productivity gains may help but are unlikely to solve the problem entirely
- Earlier policy action generally allows for more gradual, manageable transitions
Social Security’s Role in the Federal Debt Explosion: Past, Present, and the Reform Imperative
Romina Boccia and Ivane Nachkebia focused specifically on Social Security and its relationship to long-term federal debt growth. The presenters argued that Social Security has been operating with cash-flow deficits since 2010 and that these deficits contribute directly to federal borrowing. Their presentation challenged common public assumptions regarding the Social Security Trust Fund, arguing that the trust fund largely reflects internal government accounting rather than independently saved financial assets available to pay future benefits. The presentation also examined how demographic changes, rising life expectancy, wage-indexed benefit growth, and the current structure of the program contribute to long-term cost pressures. International retirement reforms implemented in countries such as Canada, Sweden, Germany, and New Zealand were reviewed as examples of how other nations have responded to similar fiscal and demographic challenges
- Social Security cash-flow deficits have contributed to federal borrowing for many years
- The presenters argued that the trust fund does not fully eliminate long-term financing concerns.
- Demographic trends and program design both contribute to rising costs
- Several countries have already implemented significant retirement-system reforms
- Delayed reform may increase future fiscal and political pressures
The Politics of Sovereign Debt (and Retirement)
Layna Mosley examined sovereign debt through a political economy lens, focusing on how political institutions, public trust, financial markets, and fiscal decision-making shape a country’s ability to manage rising debt burdens. The presentation argued that sovereign debt challenges are not simply technical budget problems, but are deeply connected to democratic governance, institutional credibility, and political incentives. Mosley discussed how governments often face “incentives to delay adjustment” because both “tax increases and spending cuts [are] perceived as unpopular.” She also explored whether the United States remains “exceptional” because of the dollar’s global reserve currency role and the long-standing assumption of “zero (or near zero) risk of default.” At the same time, the presentation noted growing concerns about “institutional erosion, reduced transparency, disregard for rule of law,” and “growing debt servicing burdens.” Mosley further highlighted the political sensitivity surrounding retirement systems and fiscal adjustment, particularly as governments weigh borrowing, tax increases, and spending reductions in response to growing deficits.
- Sovereign debt challenges are shaped by political institutions and public trust as well as economic conditions
- Policymakers often delay adjustment because spending cuts and tax increases are politically unpopular
- The dollar’s reserve currency advantage may not be permanent
- Concerns about institutional credibility, fiscal transparency, and debt servicing costs are increasingly important in sovereign debt discussions
- Retirement programs become especially politically sensitive during periods of rising debt
Federal Debt and the Future of Retirement
Kent Smetters examined how federal debt affects long-term economic growth, retirement systems, and intergenerational fairness. His presentation emphasized that public debt is not simply a budget statistic, but a broader economic issue tied to savings, investment, inflation, and the long-term transfer of financial burdens across generations. Smetters argued that focusing only on “explicit” Treasury debt can understate the government’s total long-term obligations because large entitlement commitments such as Social Security and Medicare create significant “implicit debt” as well. He also discussed how high debt levels can increase economic vulnerability if investor confidence weakens, potentially creating self-reinforcing financial stress. The presentation explored how slowing labor-force growth, demographic pressures, and rising entitlement obligations may complicate the future fiscal outlook even if technological advances such as artificial intelligence improve productivity.
- Public debt affects investment, economic growth, and retirement security
- Government debt includes both explicit Treasury debt and large implicit entitlement obligations
- Rising debt may create growing intergenerational financial pressures
- High debt levels can increase vulnerability to shifts in investor confidence
- Slowing labor-force growth and demographic change may intensify long-term fiscal challenges
