What happened
The 10-year Treasury yield (US10Y) surged to 5.24% on Monday, its highest since 2007, after Trump rejected Iran's ceasefire offer, reigniting oil and inflation fears. The 30-year bond yield climbed to 5.56% — a level not seen since 2004 — as part of a month-long rout that has added 46 basis points to the 10-year alone. Iran had proposed a seven-day plan to reopen the Strait of Hormuz — briefly giving markets hope for lower oil prices; Trump called the offer unacceptable. Brent crude jumped back toward $98 a barrel — briefly crossing $100 intraday — stoking the fear that energy-driven inflation will push the Fed to raise rates beyond its current 3.75%–4.00% target.
Why it matters
Treasury yields set the price of borrowing across the economy — when they rise, mortgages, car loans and corporate debt all get more expensive. The 30-year fixed mortgage rate has hit roughly 7.5%, a two-year high, pricing millions of buyers out of the housing market. At above 5%, the 10-year Treasury now yields more than the stock market's earnings for the first time since the dot-com era, squeezing share valuations. Any further Iran escalation could drive yields — and everyday borrowing costs — still higher.
