Bitcoin stayed volatile on Monday after Iran rejected reports of a binding 60-day deadline in its memorandum of understanding (MoU) with the U.S., undercutting an earlier market bounce tied to claims of a ceasefire extension. Iran’s Foreign Ministry spokesperson Esmaeil Baqaei said on August 17 that the MoU contained only a 60-day discussion window on sanctions relief and the nuclear issue, not an ultimatum, and said that period had become irrelevant because of what Tehran called “blatant and widespread violation” of the ceasefire. Oil rose above $83 a barrel as tensions around the Strait of Hormuz intensified, adding pressure to risk sentiment.

Al Arabiya reported the U.S. and Iran had agreed to extend the 60-day ceasefire due to expire Monday, though the report said there was no independent confirmation.
