TOKYO, July 22 (Reuters) - Japanese government bond futures rose on Monday as heightened tensions following Iran’s seizure of a British oil tanker boosted demand for safe-haven assets.

The 10-year JGB yield was flat at minus 0.140%. The two-year JGB yield was also unchanged, at minus 0.205%.
The 30-year JGB yield rose 0.5 basis point to 0.375%, while the 40-year JGB yield rose 1 basis point to 0.415%. (Reporting by the Tokyo Markets Team; Editing by Subhranshu Sahu)
