Bitcoin began Friday, October 1, at $84,000 and rallied toward $87,000 after disappointing U.S. jobs data reduced expectations for Federal Reserve rate hikes. The cryptocurrency later returned to its starting price, adding and losing $50 billion during the day as markets reacted to a reported tanker strike in the Strait of Hormuz. UKMTO (United Kingdom Maritime Trade Operations), a Royal Navy-run center monitoring threats to merchant shipping, said a tanker was hit at 11:22 UTC during an outbound transit. The impact caused a small fire and power loss, but the crew extinguished the blaze and continued sailing; no casualties or pollution were reported. UKMTO did not identify the vessel or attacker, while viral posts on X blamed Iran and authorities continued investigating. The incident followed a fire on the Kuwait-flagged supertanker Kazimah III a day earlier, and Seatrade said vessels faced at least 16 attacks in the strait during September. Bitcoin was rejected near $87,000 for the third time in two weeks, following peaks on September 22 and 23. Oil prices moved far less, with U.S. crude spot near $93.70 and Brent spot near $106.30, both up less than 0.25% on the latest candles. Brent futures had earlier fallen 2.89% to $99.35 amid reports that European Union and International Energy Agency members were considering stockpile releases. Emirates NBD senior economist Daniel Richards said renewed U.S. military deployments were sustaining the oil risk premium. Axios reported that Washington had sent two additional Patriot missile batteries to Saudi Arabia and Qatar and was moving a third carrier strike group into the region. President Donald Trump has also said he is considering renewed bombing, a threat that has weighed on oil and Bitcoin markets for weeks. Traders are now watching whether Bitcoin can break above $87,000 while the Strait of Hormuz remains under attack.
