A bond market rally following the US-Iran ceasefire has sparked hope for cheaper borrowing for Japanese companies, with Bridgestone Corp. postponing its planned bond sale to monitor conditions. The move reflects anticipation that sustained peace could lower yields on Japanese government bonds (JGBs), which fell by up to 5 basis points to 2.355% after President Trump's announcement. A 20% drop in the number of Japanese corporate bond deals prepared so far this year underscores the market's sensitivity to yield movements.
