Iran war cost hits $47 billion; Trump mulls post-election strikes

What happened

The cost of the U.S. war against Iran has risen to over $47 billion, according to a Pentagon estimate reported by Reuters. The Hill adds that this is an increase of more than $3 billion since last month, with munition replacement as the largest cost component. President Trump is considering launching strikes against Iran after the U.S. midterm elections, and food and household brands warn of more price hikes as war costs bite.

What it means for markets

Rising war costs and potential post-election strikes add uncertainty for energy markets, likely supporting crude oil prices. Consumer staples companies flagging further price hikes suggest persistent inflation pressure, which could weigh on consumer discretionary stocks and keep Treasury yields elevated.

What to watch

• Any post-election strike decision by President Trump
