Renewed fighting with Iran is pushing oil, mortgage rates, and government borrowing costs up at the same time, which is bad for anyone with a loan, a house payment, or money in stocks.

• Mortgage rates hit their highest level since mid-2025 after new Middle East attacks lifted oil prices.
• Investors are selling US government debt, sending the 10-year yield to a 19-month high and making everything more expensive to borrow.
• Trump calls the Iran fight a "little war," while senior military leaders formally objected that a long campaign is not sustainable with current ships, planes, and people.
• A new Venezuela oil deal was announced, but it would take years to reach refineries and will not cut gas prices soon.
• Big money keeps flowing into AI data centers — Anthropic signed a $35 billion cloud deal with Nvidia-backed Lambda — while the national debt tops $40 trillion and interest alone runs about $1 trillion a year.

Outlook: If the strikes continue and bond yields stay high, borrowing costs will keep climbing and stocks will stay under pressure despite strong corporate profits.
