Global Bond Yields Stabilize After U.S.-Iran Clashes Trigger Sharpest Sell-Off in Months

Global government bond yields stabilized on Friday, providing a moment of calm for fixed-income markets after experiencing their most significant two-day sell-off in months. The sharp rise in yields was triggered by an escalation in military hostilities between the United States and Iran, which has stoked investor fears of a new wave of inflation fueled by surging energy prices.

Yields Consolidate Near Highs

Following the sharp sell-off on Wednesday and Thursday, major sovereign bond yields held near recent peaks. According to market data on Friday:

• The benchmark 10-year U.S. Treasury note yield eased slightly to 4.54%, consolidating near a two-month high.
• The 2-year U.S. Treasury yield, which is highly sensitive to Federal Reserve policy expectations, hovered at 4.18%.
• Germany’s 10-year Bund yield, the benchmark for the eurozone, was trading at 3.033%, holding close to a seven-week high.

This period of stabilization follows a dramatic spike earlier in the week, as investors rapidly repriced risk in response to the geopolitical flare-up.

Geopolitical Tensions Rewrite Inflation Outlook

The bond market turmoil was a direct reaction to the collapse of a fragile June 17 ceasefire between Washington and Tehran. The situation escalated after the U.S. launched strikes against Iranian targets, prompting retaliatory attacks by Iran on American assets in Kuwait and Bahrain.

This conflict immediately threatened maritime security in the Strait of Hormuz, a critical chokepoint for global oil shipments. The disruption sent Brent crude prices surging back toward $78 a barrel, abruptly altering the near-term outlook for inflation. Prior to this week's events, bond markets had been pricing in the likelihood that moderating inflation would allow major central banks to maintain a neutral policy stance. Those assumptions are now being seriously questioned.
