The Great Misallocation: Debt Soars, Productivity Stalls

(Analysis) The OECD’s Global Debt Report 2025, released today, paints a sobering picture of a world awash in debt—$77 trillion in sovereign bonds and $35 trillion in corporate bonds by year’s end—yet alarmingly detached from the productive investments needed to sustain economic vitality.

This unprecedented borrowing, rather than fueling long-term growth, has largely financed refinancing operations, shareholder payouts, and recovery from past crises.

As Western economic scholars have long cautioned, such a trajectory risks undermining stability and prosperity. What does this mean for the global economy? A synthesis of their insights reveals a system teetering on the edge of fragility.

Sovereign Debt: A Keynesian Dilemma Meets Hayekian Warnings

John Maynard Keynes, the architect of modern fiscal interventionism, argued that government borrowing could stabilize economies during downturns, as seen post-2008 and during the COVID-19 pandemic.

The OECD data reflects this legacy: sovereign debt in OECD countries has soared from  $14 trillion in 2023 to a projected $17 trillion in 2025, with the U.S. ($4.9 trillion) and China ($2.1 trillion) leading the charge.

Yet Keynes also emphasized that such deficits should pave the way for investment-led growth—a condition unmet here.

The report notes that much of this debt has not funded infrastructure or innovation but rather plugged fiscal gaps and refinanced old obligations at rising costs, with interest payments now outstripping defense spending at 3.3% of GDP.

Friedrich Hayek, Keynes’s intellectual rival, would see this as a harbinger of malinvestment. His Austrian School perspective warns that excessive borrowing distorts price signals and resource allocation, creating bubbles that inevitably burst.

The OECD’s observation that 42% of sovereign debt matures in the next three years—amid doubled borrowing costs since 2021—echoes Hayek’s fears of a reckoning.

Governments face a refinancing cliff, potentially triggering the “negative feedback loop” of rising rates and sluggish growth that Hayek cautioned against.

Corporate Debt: Schumpeter’s Innovation Stifled

Joseph Schumpeter, the champion of creative destruction, viewed debt as a tool for entrepreneurial risk-taking—financing the innovations that drive capitalism forward.

Yet the OECD reveals a stark deviation: corporate bond debt hit $35 trillion in 2024, with issuances since 2009 ($12.9 trillion) dwarfing investments ($8.4 trillion).

Non-financial firms, doubling their debt since 2008, have prioritized refinancing and shareholder dividends over productive capacity.

Schumpeter might argue this misallocation stifles the “gales of creative destruction,” leaving firms ill-equipped to generate the returns needed to service their obligations as 38% of this debt matures by 2028.

Milton Friedman’s monetarist lens adds another layer of concern. He stressed the destabilizing effects of loose credit when unmoored from real economic output.

The OECD’s critique—“companies used the low interest rate era to prioritize financial operations”—suggests a Friedman-esque disconnect between monetary expansion and tangible growth, risking inflation or asset bubbles as central banks unwind their 19% share of sovereign bonds (down from 29% in 2021).

Emerging Markets: Stiglitz’s Inequality Trap

Joseph Stiglitz, a modern critic of global financial architecture, would highlight the report’s findings on emerging markets, where sovereign debt has tripled to $12 trillion since 2007.

China’s 45% share of 2024 issuance underscores its rise, but the broader trend reflects what Stiglitz calls an unequal burden: developing economies borrow heavily yet lack the fiscal space of richer nations to invest productively.

With growth projected at a modest 3.2% through 2025—below historical norms—these countries face a debt trap, exacerbated by a shifting investor base (households and foreign buyers now hold 45% of OECD debt, up from 34% in 2021), which could demand higher yields and deepen volatility.

A Piketty Perspective: Debt as Inequality Amplifier

Thomas Piketty, whose work ties capital accumulation to inequality, might interpret this debt surge as a symptom of wealth concentration.

The OECD notes that corporate borrowing has enriched shareholders rather than workers or innovation, while sovereign debt refinances past largesse rather than future equity.

As interest burdens rise—consuming budgets that could fund social goods—Piketty would argue this entrenches disparities, with the top 1% benefiting from financial maneuvers while public services erode.

The Path Forward: Krugman’s Pragmatism vs. Rogoff’s Austerity

Paul Krugman, a Keynesian pragmatist, might advocate for strategic borrowing to jolt economies out of stagnation, especially for climate transition (sustainable bonds hit $325 billion).

He’d likely endorse the OECD’s call to redirect debt toward “productivity-enhancing” investments, arguing that growth can outpace debt if targeted wisely.

Yet Kenneth Rogoff, co-author of This Time Is Different, would counter that debt-to-GDP ratios nearing 85% in OECD countries signal a tipping point.

His historical analysis suggests that such levels often precede crises unless paired with austerity—a politically fraught prospect given aging populations and defense needs.

Conclusion: A Call for Recalibration

The OECD’s 2025 report is a clarion call: record-breaking debt issuance, unmoored from investment, imperils global stability.

Keynes and Krugman urge strategic spending; Hayek and Rogoff demand restraint; Schumpeter and Stiglitz seek purpose in capital flows.

Together, they frame a stark reality—without a pivot to productive use, this debt mountain risks collapsing under its own weight.

Governments and firms must heed the OECD’s advice: prioritize growth-enhancing investments and reform financial incentives. The alternative—a cascade of defaults or stagnation—looms as a threat too grave to ignore.
