Guilty by association?

European investment-grade credit has underperformed US credit mainly because sovereign volatility has spilled over into European corporate bonds, not because European companies have materially weakened.

• Government bond volatility intensified as the 10-year US Treasury yield reached 5.36%, while 30-year UK Gilts reached 6% and 10-year German Bunds 5.36%.
• France’s projected 2027 deficit declines only from 5.4% to 5.0% of GDP, public debt rises to 121.7% of GDP, and the OAT-Bund spread touched 150 basis points; Italy’s 10-year yield rose nearly 50 basis points in September.
• US investment-grade spreads widened only 4 basis points in September, versus 12 basis points for European investment grade, while European high-yield spreads widened 41 basis points compared with 48 basis points in the US.
• European bank fundamentals remained strong in the ECB’s second-quarter 2026 data: CET1 capital was 16.0%, return on equity 10.7%, non-performing loans 2.17%, and the liquidity coverage ratio about 155%; European high-yield defaults fell to 0.5% in September.
• European funds nevertheless recorded approximately $2.7 billion of outflows in the week ended 16 September and another $1.9 billion in the final reporting week of September, while European high-yield and investment-grade markets have much less AI and hyperscaler exposure than the US.

Takeaway: The repricing may offer additional yield without a comparable rise in corporate credit risk, but spreads could remain under pressure if sovereign volatility and weak market technicals persist.
