Oil prices tumbled Tuesday as traders once again priced in a U.S.-Iran agreement before anyone had actually signed one. Treasury Secretary Scott Bessent said a deal could come Tuesday or Wednesday, while Secretary of State Marco Rubio said talks involving Iran and Oman had made progress. President Donald Trump went further, calling an agreement to reopen the strait and denuclearize Iran “imminent.” Iran is also seeking control over inbound shipping and visibility over outbound traffic, with the ability to intervene when it sees fit. Oil has spent months whipping between peace headlines and missile strikes while physical flows remain badly impaired.
