U.S. 10‑year Treasury yield rose 3.2 bps to 4.386% after earlier falling to 4.314%, its lowest since April 27.
Yield increase followed reports that Iran rejected a U.S. plan to reopen the Strait of Hormuz, a key route for ~20% of global oil and LNG.
Crude oil prices rose, with U.S. WTI at $95.10/barrel (session high $97.46) and Brent at $100.65/barrel (down 0.61% from $102.49).
Earlier yields had dropped when a limited temporary cease‑fire was being discussed, but reversed as tensions persisted.
