Bitcoin rose above $64,600, trading at $64,611 after moving between $64,005 and $64,926, as U.S. President Donald Trump said Washington was not in talks with Iran and oil stayed elevated amid conflicting claims over the Strait of Hormuz, a key global energy shipping route. Trump said no U.S.-Iran negotiations were underway or scheduled and wrote that the naval blockade remained in force while the strait was open and operating, with water mines removed or detonated. Iran disputed that account. Reuters said chief negotiator Mohammad Baqer Qalibaf maintained the waterway would remain closed until Washington met conditions in a June 17 interim agreement, including lifting the U.S. blockade of Iranian ports, removing oil sanctions, releasing frozen Iranian assets, and ending U.S. military threats and operations. Brent crude rose 0.7% to $91.46 per barrel and U.S. West Texas Intermediate gained 0.9% to $85.25, extending oil's advance to a third session. Strategy, the largest publicly traded corporate holder of Bitcoin, reported no Bitcoin purchases or sales between Aug. 10 and Aug. 16, leaving its holdings at 840,447 BTC acquired for $63.36 billion at an average price of $75,385 per coin. The pause followed two straight weeks of disposals. Markets were also watching an Aug. 19 White House meeting expected to include crypto firms and regulators including the SEC (U.S. securities regulator) and CFTC (U.S. derivatives regulator), as debate over the Digital Asset Market CLARITY Act continued.
