Wars raise mortgage rates via oil

A regional war (here, involving Iran) can push oil prices up, which raises inflation and risk premia and quickly filters into higher long‑term borrowing costs—lifting 30‑year mortgage rates and undermining housing affordability even as inventory rises. That transmission means foreign conflicts can have immediate, measurable effects on ordinary homebuyers and local housing markets. — Makes explicit that foreign military events are a direct driver of domestic housing affordability and therefore a relevant factor in political debate over both foreign policy and housing policy.
