Oil plunged over 10% as Iran briefly reopened the Strait of Hormuz during an Israel-Lebanon ceasefire, lifting broader peace hopes, though ING warned 13 million barrels per day remain disrupted. The hope that the Middle East conflict may be nearing an end helped power a stock rally, alongside strong bank earnings and upbeat CEO comments, as the Nasdaq posted its longest winning streak since 2021. Domestically, U.S. jobless claims fell to 207,000, signaling labor resilience, but continuing claims rose to 1.818 million. Meanwhile, China is hardening its legal toolkit ahead of Trump’s May 14-15 Beijing visit.

On Thursday, Live Nation was ruled as a Monopoly in a Victory for States, raising potential breakup pressures.
