Bond Yields Soar as Geopolitics Fuel Inflation Fears

Government bond yields have surged to their highest levels in mid-August 2026 across the US, UK, and eurozone. The rise is attributed not to changes in Federal Reserve policy but to inflation fears caused by geopolitical instability.

The recent surge in Brent crude oil prices has been a significant catalyst for the bond selloff. With prices reaching nearly $90 per barrel, Brent crude has climbed 2.6% in a single session and approximately 13% over the preceding week following stalled US-Iran peace negotiations.

Despite the Federal Reserve keeping policy rates steady, long-term borrowing costs are increasing. The US bond market alone holds over $58 trillion in assets, making it a major force that can move independently of any institution's decisions.
