Oil prices surged and government bond yields climbed Monday as President Trump escalated threats against Iran, raising fears of potential Middle East supply disruptions. Trump warned he would destroy all of Iran's power plants if Tehran doesn't reopen the Strait of Hormuz by Tuesday evening, a deadline he moved from the previous 10-day window. Front-month WTI crude oil futures rose 0.9% to $112.53 per barrel and Brent crude climbed 1.7% to $110.84. This spike in energy costs weighed heavily on bond markets, pushing yields higher. The 10-year Japanese government bond yield jumped 2 basis points to 2.400% and the U.S. 10-year Treasury yield increased 4 basis points to 4.3575%, reflecting concerns that higher oil prices could fuel inflation and delay central bank rate cuts.
