A global sell-off in government bonds has intensified, driven by a surge in oil prices and concerns over inflation and impending interest rate hikes. Brent crude climbed to $106.31 a barrel, following President Donald Trump's rejection of Iran's latest proposal regarding the Strait of Hormuz, which further fueled inflation worries. This oil price rise, coupled with hawkish comments from Federal Reserve officials, is pushing bond yields higher worldwide.

US Treasury yields are experiencing significant increases, with the rate-sensitive two-year bonds rising five basis points to 4.90% and the 10-year yield climbing four basis points to 5.20%. The 30-year Treasury bond yield, more susceptible to geopolitical risks, also moved up to 5.5162%. This broad sell-off is not confined to the US, as sovereign bond yields in Japan, Australia, and South Korea have also fallen, and European bonds like UK gilts and German Bunds are also under pressure.

Market analysts like Damien McColough of Westpac Banking Corp attribute the bearish sentiment to the hawkish Fed messaging and oil prices staying above $100. Swap markets are now pricing in at least three more interest rate hikes from the Fed next year, with a potential for a fourth. The bond market is nearing a curve inversion, where the 10-year yield could fall below shorter maturities, a phenomenon often indicating an impending economic slowdown. The ongoing developments in the Middle East, particularly around the Strait of Hormuz, are expected to remain a primary focus for markets, influencing future bond movements and Federal Reserve decisions.
