Oil prices extended their retreat Monday as traders processed the U.S.-Iran ceasefire agreement, with Brent crude sliding in a second consecutive session and the war-risk premium that had buoyed energy markets over recent weeks quietly disappearing into the settlement tape.

Equity markets offered no clear direction. Stocks traded mixed after a strong run the session prior, with the energy sector absorbing the most visible pressure as the supply-disruption scenario that had been priced into contracts began to look like a false alarm.

The ceasefire, confirmed over the weekend, removed the primary catalyst traders had been citing for elevated crude valuations — the threat of Iranian export disruption or a broader regional supply shock. With that threat off the table, the arithmetic changed quickly.

The New York Times reported the moves on June 16, 2026, noting markets were still digesting the terms of the deal.
