The Shifting Tides of Fiscal Discipline and Demographic Decline

The world’s economy is at a critical juncture, facing a perfect storm of fiscal recklessness and demographic decline that threatens to upend global economic stability. J.P. Morgan’s recent warning about the impending spike in interest rates due to dwindling populations and diminishing fiscal discipline serves as a stark reminder that the era of easy borrowing is coming to an abrupt end.

The six D’s outlined by JPMorgan – deficits, deregulation, de-carbonization, de-population, de-globalization, and de-dollarization – are all contributing to a perfect storm of fiscal instability. However, it’s the two most pressing concerns – deficits and de-population – that will have the most profound impact on borrowing rates worldwide.

Global public debt has reached an unprecedented $100 trillion. The conventional wisdom suggests that as governments accumulate more debt, they become less creditworthy, prompting central banks to increase money supply to reduce the value of the debt and create inflation. However, this simplistic view overlooks the complexity of modern fiscal policies. Governments have been relying heavily on fiscal stimulus – increased spending or tax cuts – during times of crisis, such as the 1979 Iran hostage crisis. These increases in deficits come without well-identified offsets, leaving few signs of rebuilding fiscal space.

The US economy, the largest and safest in a time of global turmoil, is particularly precarious. The unsustainable US fiscal deficit has not yet caused significant damage to the economy, thanks to its relatively robust fiscal space compared to other countries. However, any dramatic setbacks – military, political, energy security, or economic – that undermine America’s status as the strongest nation could have far-reaching consequences for the debt outlook.

Advanced economies are facing a pressing demographic challenge: declining birth rates and aging populations. This shift will lead to a smaller labor supply to pay for goods and services needed by an older, non-working population. Demand for pension and healthcare expenditures will rise, while demand for public investments such as defense, renewable energy, and infrastructure will intensify. Without offsetting measures like higher government revenues or spending cuts, these pressures imply a substantial increase in public debt across jurisdictions beyond 2031.

The Committee for a Responsible Federal Budget’s Social Security Countdown stands at seven years and ten months, with neither political party expected to act until the cliff is met in 2032. Addressing the shortfall would require issuing approximately $600 billion in debt and potentially further spending cuts and higher taxes. The demographic challenges will lower savings, highlighting the risk that aging populations and longevity could drive down equilibrium returns, even for funded systems.

The demographic dividend of the last 40 years is ending, and de-population is an underappreciated risk that will reduce savings and contribute to higher interest rates. As governments grapple with these twin challenges, they must confront the reality that the era of easy borrowing is over. Fiscal discipline and demographic stability are essential for sustained economic growth. The world’s policymakers would do well to take heed of J.P. Morgan’s warning and take decisive action to address these pressing issues before it’s too late.

The global economy stands at a crossroads, with two paths diverging: one marked by fiscal responsibility and demographic sustainability, the other by reckless spending and population decline. The choice is clear – but will policymakers have the courage to act?
