JPMorgan warns deficits, aging populations to lift global interest rates
Rising global debt loads are keeping focus on what could push borrowing costs higher through the end of 2026. JPMorgan says weakening fiscal discipline and aging populations are emerging as two of the strongest pressures on interest rates across major economies.
Highlights
- JPMorgan forecasts that global deficits and de-population will raise borrowing costs, with public debt reaching $100 trillion and sustained elevated deficits.
- The bank warns U.S. debt and political resistance to fiscal consolidation will increase term premiums on long-dated bonds, though the U.S. retains relative fiscal space during crises.
- JPMorgan projects demographic change will drive higher demand for pensions, healthcare, and infrastructure, implying rising public debt beyond 2031 and exposing a $600 billion Social Security funding gap by 2032.
JPMorgan note outlines pressures on borrowing costs
As reported by Fortune, a note from JPMorgan led by Joyce Chang identifies deficits and de-population as two of the six forces shaping the global economy, alongside deregulation, de-carbonization, de-globalization and de-dollarization. The bank argues that these two factors are likely to put upward pressure on borrowing rates around the world.On fiscal policy, the note says a global breakdown in discipline is occurring as public debt reaches $100 trillion and elevated deficits push rates higher. JPMorgan adds that governments have relied heavily on fiscal stimulus during the Iran crisis, while failing to pair spending increases or tax cuts with clear measures to rebuild fiscal space.
The bank says the U.S. faces a larger stock of debt, higher interest rates and little political will for near-term fiscal consolidation, a mix that points to a higher term premium on long-dated bonds. At the same time, it says the U.S. economy has so far avoided major damage because it retains more fiscal space than many other countries and is still viewed as the safest and strongest market during geopolitical upheaval.
Aging trends add to long-term debt risks
JPMorgan also highlights demographic change in advanced economies, where falling birth rates and aging populations are shrinking the labor force that supports a growing retired population. That trend is raising expected demand for pensions and healthcare at the same time governments face heavier investment needs in defense, renewable energy and infrastructure.Without offsetting steps such as higher revenue, cuts in other spending or changes in the interest rate-growth balance, the bank says these pressures imply a substantial rise in public debt across jurisdictions beyond 2031. It also points to the U.S. Social Security funding gap, saying neither political party is expected to act before the projected 2032 cliff, a shortfall that could require about $600 billion in additional debt issuance as well as deeper spending cuts and higher taxes.
JPMorgan says demographic pressures may also reduce savings and lower equilibrium returns, leaving even funded systems under strain. In the bank's view, the demographic dividend that defined the past 40 years is ending, making de-population an underappreciated risk for global rates markets.
Our earlier article on Fitch’s negative outlook revision for Cranston, Rhode Island focused on mounting fiscal strain driven by rising expenditures without matching revenue growth. It highlighted how growing pension liabilities and elevated debt levels can put municipal bond ratings under closer scrutiny as officials try to stabilize finances amid a mixed economic backdrop.
