Are war-driven deficit fears pushing long-term government bond yields higher?
Core argument: The 30-year Treasury yield rose to close to 4.90%, its highest in a month, as investors worried the Iran war will lift spending and swell budget deficits across countries.
Investors are growing worried that the Iran war will drive up expenditures and swell budget deficits in countries around the world, sparking a selloff in long-term government bonds. The move has driven the 30-year Treasury yield to close to 4.90%, the highest in a month, as markets are already worrying over oil-driven inflation fret governments will need to borrow more to pay for defense spending and to shield households from higher energy costs. More broadly, global bonds have surrendered their year-to-date gains. Bond yields have spiked from the UK to Germany to Australia to Japan. A wave of government borrowing globally could put further pressure on the $31 trillion US Treasury market, should investors opt for higher yields elsewhere. Bloomberg’s gauge of Treasuries returns has almost wiped out its gains for this year.
