The escalating war in Iran, triggered by U.S.-Israeli strikes that killed Supreme Leader Ayatollah Khamenei, has plunged global markets into chaos, trapping U.S. Treasuries investors in a brutal stagflationary oil dilemma. U.S. Treasuries, fresh off their best month since last year with 10-year yields dipping below 4%, saw a dramatic reversal as oil prices surged past $70 per barrel (Brent up 13% year-on-year), reviving inflation fears and sparking a bond sell-off.
Market Reversal Explained
Bond markets flipped from safe-haven buying frenzy to panic selling. 2-year Treasury yields jumped 10 basis points to 3.48%, while 10-year yields soared to 4.03%—the biggest daily slump since October—erasing recent gains. Investors now debate: pile into Treasuries for geopolitical risk-off protection amid stock slumps, or dump them fearing oil-driven inflation that could halt Fed rate cuts or even spark hikes.
Oil’s inflationary punch is stark—a $10/barrel rise adds 0.2% to annual inflation, pushing the Fed’s gauge from 3% higher amid hot January producer prices. Analysts like Mizuho warn $100-130 oil could kill rate cuts entirely, echoing Russia’s 2022 Ukraine invasion shock.
Investor Dilemma Deepens
The “bull case” for bonds persists via AI job disruption threats bolstering long-term safe-haven demand, but persistent oil spikes threaten broader price pressures. Rabobank notes oil’s shift from deflationary to highly inflationary, complicating central bank paths worldwide. Rate-cut bets trimmed sharply, with June Fed easing odds slashed as yields on German bonds and others followed suit.
