Global Bond Yields Stabilize After U.S.-Iran Tensions Trigger Sharp Sell-Off

U.S. Treasury and eurozone government bond yields held steady on Friday, providing a moment of calm for fixed-income markets after experiencing their most significant two-day spike in months. The pause follows a sharp sell-off triggered by fears that a military escalation between Washington and Tehran could unleash a new wave of energy-driven inflation.

Geopolitical Shock Hits Markets

The sudden repricing in bond markets came after the United States and Iran exchanged heavy military strikes, effectively shattering a fragile June 17 ceasefire. According to reports, the conflict involved U.S. strikes on Iranian targets, followed by retaliatory attacks by Tehran on American assets in Kuwait and Bahrain.

This escalation has severely disrupted maritime traffic through the Strait of Hormuz, a critical chokepoint for global oil shipments. The immediate market reaction saw Brent crude prices surge back toward $78 a barrel, forcing investors to rapidly reassess near-term economic outlooks.

Inflation Fears Resurface

The spike in energy prices has directly challenged the prevailing market narrative that cooling inflation would allow major central banks to maintain a neutral monetary policy stance. The prospect of higher energy costs feeding into headline inflation has upended those assumptions, leading investors to sell off government bonds, which causes their yields to rise.

The yield on the benchmark 10-year U.S. Treasury note eased slightly to 4.54%, consolidating near a two-month high. Other key benchmarks also held near recent peaks:

• The 2-year U.S. Treasury yield, which is highly sensitive to Federal Reserve rate expectations, hovered at 4.18%.
• Germany’s 10-year Bund yield, the benchmark for the eurozone, held near a seven-week high at 3.033%.
