Investors in government bonds are like Titanic passengers who didn't worry immediately after hitting the iceberg. High government debt and deficits are the "icebergs" we've already hit, but the market remains complacent, not realizing the imminent danger to the financial system.
Governments with high debt cannot simultaneously keep yields low, maintain a strong currency, and avoid austerity. Guest Alberto Gallo argues one of these pillars must break, with currency debasement being the most likely initial outcome, followed by a potential credit market crisis.
The credit market is like a Jenga tower with government bonds at the base and risky private debt at the top. When government yields were near zero, investors were forced up this tower for returns. Now, with safe government bonds offering high yields, the incentive to hold illiquid, risky private debt is collapsing.
The AI infrastructure boom, the second largest capex event in U.S. history, is heavily funded by private credit. Over 40% of this market is concentrated in the tech and software sector, with a similar percentage of borrowers being free-cash-flow negative, creating a massive, concentrated credit risk.
About 10% of private credit funds use 'Payment-in-Kind' (PIK) structures, where companies pay interest with more debt instead of cash. These are 'Schrödinger's defaults'—not technically in default but lacking the cash flow to service their debt, hiding potential losses until a refinancing event.
Life insurers are the largest holders of private credit. Because their policyholders are guaranteed by state governments, a wave of defaults in opaque private credit assets could trigger bailouts. This creates a hidden contagion path where private market losses are ultimately passed on to the taxpayer.
Hyperscalers finance their data center buildout off-balance-sheet through third parties that borrow at high rates. This strategy keeps massive capex and leverage off their own books, protecting their investment-grade credit ratings and making it easier to walk away from excess capacity if demand falters.
While corporate bond yields seem attractive, this is almost entirely due to high government rates. The actual credit spread—the premium investors receive for taking default risk—is at a multi-decade low. Investors are being poorly compensated for the risk they are taking on corporate balance sheets.
