Japanese government bond (JGB) yields rose on Thursday as higher oil prices, triggered by escalating tensions between the United States and Iran, stoked inflation concerns and reinforced investor worries over Japan's fiscal outlook.
According to Reuters, crude oil prices extended gains for a fourth straight session after a fresh wave of U.S. strikes on Iranian military installations heightened fears of a broader conflict and potential supply disruptions through the Strait of Hormuz. The rise in energy prices added to expectations that inflationary pressures could remain elevated.
