Why did Treasury yields rise after Trump's renewed threats against Iran?

Treasury yields rose because Trump's threats of military action against Iran over Hezbollah's attacks on Israel stoked fears of escalating Middle East tensions, pushing oil prices higher and prompting investors to reassess inflation risks—complicating the Federal Reserve's efforts to tame inflation; additionally, the bond market was playing catch-up after Friday's cash-market holiday, and hawkish messaging from Fed Chairman Kevin Warsh reinforced expectations of a potential rate hike by September.

What specific oil price movements and Treasury yield changes were reported following Trump's statements?

Following Trump's social media threats, Brent crude climbed as much as 2.2% to $82.30 a barrel and West Texas Intermediate neared $77; meanwhile, 10-year Treasury yields rose as much as five basis points to 4.50% in Asia on Monday, and two-year yields—most sensitive to policy changes—climbed to 4.22%.
