US federal debt nears $40tn as deficits, interest costs and private credit defaults strain markets

US federal debt is nearing $40trn, with the Treasury’s tally at about $39.987trn as of 17 August, set against $5.17trn of consumer borrowing and $14.45trn in non-financial corporate debt in Q1, up roughly 5% year on year. July’s budget figures showed a $432.31bn monthly deficit, although a weekend calendar shift pulled around $99bn of August benefits into July, trimming the adjusted shortfall to about $333bn; even then it was 18% higher than a year earlier. July spending reached $766.31bn, a 22% rise from July 2025, or roughly $677.31bn excluding that timing effect. Tariff refunds of $33.38bn pushed net tariff revenue to negative $8.55bn, after earlier monthly collections of roughly $30bn to $40bn. Interest remains a growing strain: July interest paid was $117.57bn versus roughly $185bn in June, and interest expense over the first 10 months of FY2026 hit about $1.17trn, up 15.5%.

Attention is also on the $1.4trn private credit market, around 10% of non-financial corporate debt, where Fitch put the US default rate at 6% at end-May and recorded 14 defaults in May alone. A Blue Owl fund posted a 2.8% Q2 default rate, while reported defaults at Ares, Blackstone, Blue Owl, and Golub were at their highest since 2021, alongside five-year highs in nonperforming loans at other funds. Software exposure is large, at 20% or more of outstanding debt at many private credit funds. In commodities, gold traded above $4,400 an ounce and silver above $65, while central banks bought 289 metric tons of gold in Q2, nearly five times Q1.

US Debt Milestone and Fiscal Pressure on Derivatives Markets

We are staring directly at a historic $40 trillion U.S. national debt milestone that will inevitably reshape the derivatives landscape in the coming weeks. With the federal deficit already hitting $1.8 trillion for fiscal year 2026 and interest expenses climbing past $1.1 trillion, the fiscal pressure is reaching a boiling point. As derivative traders, we must prepare for heightened volatility as the market realizes the Federal Reserve has very little room to maneuver.

The real danger lies in the $1.4 trillion private credit market, where defaults are starting to quietly climb. Much like the subprime mortgage crisis in 2008—which triggered a global collapse despite representing only about 13% of the housing market—private credit now makes up 10% of corporate debt and is showing severe stress. We need to position ourselves for a potential liquidity squeeze as these hidden defaults begin to leak into the broader financial system.

Credit Strategies, Metals Momentum, and Portfolio Protection

To capitalize on these deteriorating credit conditions, we should target bearish option strategies on Business Development Companies (BDCs) and high-yield debt instruments. Recent reports show major players like Blue Owl experiencing five-year high default rates of 2.8%, while Fitch tracked a staggering 6% overall private credit default rate earlier this year. Buying out-of-the-money puts on credit-heavy ETFs and major private lenders offers a high-reward asymmetry as internal watch lists continue to grow.

At the same time, we must leverage the unprecedented momentum in precious metals, with gold holding strong above $4,400 and silver surpassing $65. Central banks bought a massive 289 metric tons of gold in the second quarter of 2026 alone, demonstrating a global flight from the dollar. Going long on gold call options or utilizing bull call spreads will allow us to ride this macro wave while hedging against systemic banking risks.

Finally, we must brace for sudden market swings by purchasing long-dated VIX call options to protect our portfolios. The combination of massive corporate debt, which sits at $14.45 trillion, and potential AI disruptions in the heavily leveraged software sector could trigger a sudden sell-off. Hedging our positions now ensures we are prepared when the slow accumulation of debt risks suddenly turns into a rapid market correction.
