Global government bond markets are on track for their steepest monthly decline in years during March 2026, driven by a prolonged Middle East conflict that has sent oil prices soaring and reignited fears of persistent inflation coupled with slowing economic growth. The selloff represents a rapid repricing of interest-rate expectations and a broad retreat from fixed-income assets worldwide.
Yields have climbed sharply across major economies. In the United States, the two-year Treasury yield is set for a rise of approximately 50 basis points this month—its largest increase since October 2024—while the 10-year yield has climbed about 44 basis points to roughly 4.39%. The moves in Europe have been even more pronounced. The UK’s two-year gilt yield has jumped 98 basis points, marking its biggest monthly increase since the 2022 market turmoil. Germany’s two-year yield rose 69 basis points, with its 10-year yield reaching a 15-year high of 3.13% last week.
The primary catalyst is a historic surge in oil prices, with crude climbing above $100 per barrel from around $70 in late February, marking its largest monthly percentage increase in decades. While initial market reactions centered on inflation risks, analysts note a growing focus on the potential hit to global economic growth from sustained high energy costs.
This has led to a significant reset in monetary policy expectations. Markets have largely abandoned earlier forecasts for interest rate cuts by the Federal Reserve in 2026. In Europe, investors now anticipate the European Central Bank and the Bank of England to deliver two to three rate hikes this year, a sharp reversal from prior expectations of easing.
Asian markets showed divergence in response. South Korea's Kospi index plunged 1.53% at the open, with the Korean won sliding to its weakest level against the US dollar since 2009, reflecting the country's high sensitivity to external energy shocks. Japan and Australia also saw declines. In contrast, Chinese markets demonstrated relative resilience, with the CSI 300 gaining 0.4%. This is attributed to China's strong crude stockpiles, expansion in green energy, and subdued inflation, with its two-year bond yields falling more than 11 basis points in March.
The geopolitical situation remains fluid, with US President Donald Trump indicating a willingness to consider ending the war without first reopening the Strait of Hormuz—a chokepoint for about one-fifth of global oil supply. While this helped ease Brent crude to around $111.56 and WTI to about $101.90, prices remain historically elevated, ensuring that the geopolitical risk premium in energy markets stays heavy and continues to drive global financial volatility.
