US Treasury Yields Diverge as French Political Unrest Sparks Flight to Safety

U.S. Treasury yields showed a notable divergence on Tuesday, with short-dated borrowing costs rising while longer-term yields declined. The move reflects a flight to safety by investors amid escalating political unrest in France, which is causing turmoil in European sovereign debt markets.

European Turmoil Pressures Bonds

A sharp escalation in civil unrest in France triggered a significant sell-off in the country's government bonds. The rout sent French sovereign yields to their largest single-day spike in nearly a month and pushed the cost of insuring French debt against default to its highest level since the 2013 sovereign debt crisis.

According to market data, five-year French credit default swaps (CDS) neared 79.05 basis points. The instability quickly spread to other European markets, with Germany's benchmark 10-year Bund yield climbing to 3.450%. This uncertainty is driving demand for the perceived safety of long-dated U.S. government debt.

A Split in the US Yield Curve

The U.S. bond market reflected this global dynamic, with yields moving in opposite directions depending on their maturity.

• The two-year Treasury yield, which is highly sensitive to Federal Reserve policy expectations, rose to 4.778%.
• The five-year Treasury yield also edged up to 4.934%.
• In contrast, the benchmark 10-year Treasury yield fell to 5.119%.
• The 30-year Treasury yield dropped to 5.446%, indicating strong institutional demand for long-duration assets.

"Investor appetite for bonds may be weighing on yields despite firmer crude oil prices," said Elias Haddad, global head of markets strategy at Brown Brothers Harriman, commenting on the demand for longer-dated Treasuries.

Fed Outlook and Market Headwinds

Beyond the geopolitical risks, investors are also weighing central bank policy and heavy corporate debt issuance. Money markets continue to price in a high probability that the Federal Reserve will keep its benchmark interest rate unchanged at its upcoming policy meeting on October 27-28, following cautious commentary from policymakers.

At the same time, the U.S. bond market is absorbing a massive supply of new corporate debt. Multi-billion-dollar bond sales from technology firms, aimed at funding artificial intelligence infrastructure, are competing with government debt for investor capital and adding a complex variable to the market.
