Global Bond Yields Stabilize After U.S.-Iran Clash Sparks Inflation Fears

Global government bond yields steadied on Friday, capping a volatile week where escalating military conflict between the United States and Iran triggered the largest spike in borrowing costs in months. The sell-off in fixed-income markets was fueled by concerns that rising energy prices, a direct consequence of the geopolitical flare-up, will reignite inflationary pressures.

Market Reaction and Key Levels

Bond markets caught their breath after a sharp two-day rout. The yield on the benchmark 10-year U.S. Treasury note eased slightly to 4.54%, consolidating near a two-month high reached earlier in the week.

Other key benchmarks reflected a similar pause:

• The 2-year U.S. Treasury yield, which is highly sensitive to Federal Reserve interest 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%.

Geopolitical Shock Rewrites Inflation Outlook

The market turbulence followed the collapse of a fragile June 17 ceasefire. According to reports, the U.S. conducted strikes on Iranian targets, which was followed by retaliatory attacks from Tehran on American assets in Kuwait and Bahrain.

The conflict sent shockwaves through energy markets, threatening maritime transit through the critical Strait of Hormuz. The disruption caused Brent crude oil prices to surge back toward $78 a barrel, forcing investors to rapidly reassess near-term inflation projections.

Shift in Central Bank Expectations

Prior to this week's events, bond markets had been rallying on the assumption that moderating inflation would allow major central banks like the Federal Reserve to maintain a neutral policy stance. The sudden prospect of a sustained period of higher energy costs has thrown that assumption into question, forcing a repricing of risk across fixed-income assets.
