Despite an outwardly calm market, a significant dislocation is developing in global credit markets, marked by record trading in credit derivatives. In the first quarter of 2026, trading volumes for derivatives protecting high-grade and junk-rated bonds in the US and Europe surged to nearly $4.5 trillion. This represents a 36% increase over the previous record, set when former US President Donald Trump imposed trade tariffs. This surge is attributed to investor anxieties regarding corporate defaults, fueled by the war in Iran and the disruptive impact of artificial intelligence on established industries.
The underlying issues contributing to this instability are substantial. The US national debt has reached $40 trillion, with daily interest payments totaling $3 billion, or $1.2 trillion annually. Interest expenses are currently the fastest-growing component of federal outlays, outpacing tax receipts and GDP growth. This escalating debt burden, combined with the Federal Reserve's balance sheet reduction efforts, which have historically destabilized credit markets, suggests that previous assumptions of sustained low interest rates are no longer valid. The 30-year Treasury yield is at its highest since 2001, and broader bond yields are at quarter-century highs.
Key indicators are flashing red for the credit market. Credit spreads, particularly between hyperscaler bonds and Treasuries, are widening, and the cost of insuring against default for these companies is increasing. This is seen as an early warning sign of a potential credit bubble collapse. The broader credit bubble includes $1.6 trillion in Private Credit, $1.4 trillion in CLO debt, $1.5 trillion in Junk Bonds, $1.4 trillion in Margin Debt, and $18.8 trillion in consumer debt. AI-related debt, while a segment, is critical as it accounts for roughly half of US earnings and GDP growth; a continued widening of its credit spreads could drastically alter market narratives around AI, productivity, and earnings momentum. The financial system, with the Fed's balance sheet near $7 trillion, is ill-equipped for another crisis, as bailouts may be met with hesitation and delayed intervention.
The global bond market is experiencing a significant sell-off, driven by renewed fighting in the Middle East pushing oil prices past $91 a barrel and anticipation of further interest rate hikes. On September 1, 2026, Japan's 10-year benchmark yield hit 3% for the first time since 1996, and the US 10-year Treasury yield reached 4.79%, its highest since early 2025. Britain's 10-year yield surpassed 5.24%, its highest since 2008, and Germany's 10-year yield rose to a 15-year high of 3.36%. These rising yields put pressure on tech companies heavily borrowing for AI investments, impacting stock markets, as evidenced by declines in US stock futures, Europe's STOXX 600 index, and Hong Kong's Hang Seng. Traders are now pricing in a 65% chance of a Fed rate hike in September, with further hikes expected from the European Central Bank.
