President Donald Trump is scheduled to make an unspecified Oval Office announcement at 2 p.m. ET on Sept. 28, according to White House guidance, while markets focus on its possible connection to Iran and the Strait of Hormuz. Trump said Saturday he rejected Tehran's seven-day proposal to reopen the strait in exchange for the lifting of a U.S. naval blockade, oil sanctions and the release of roughly $12 billion in frozen assets. Oil rose more than 1% when markets reopened Sunday evening, while bitcoin fell about 1.5% to near $83,000 after reaching a weekly close of $84,472, its highest since January. The crypto market is also entering a data-heavy week, with PCE inflation, payrolls, manufacturing and consumer-confidence reports due alongside recent Federal Reserve tightening. Bitcoin was near $83,300 after Monday's decline, while U.S. spot bitcoin ETFs attracted roughly $2.4 billion last week, their strongest week since October 2025, according to Scott Melker.
