The CoinDesk 100 index rose 0.67% to 1,926.99, but its rally narrowed sharply, with 38 of 100 constituents lower on the day. Over 24 hours, 87 constituents were higher and 13 lower, indicating that the weakening emerged in the past few hours rather than on Tuesday. Major cryptocurrencies diverged, with XRP gaining 3.3% to $1.62. Brent crude fell below $100 for the first time since Sept. 9, trading at $99.13 after reaching $108 in mid-September. The decline followed hopes for a U.S.-Iran deal, with a Qatari mediator holding talks with U.S. officials in New York and Iranian President Masoud Pezeshkian scheduled to address the UN General Assembly later today. Gold fell 0.85% to $4,321 and silver declined 2.2% to $65.53, while the dollar index rose 0.21% to 100.76 and U.S. equity futures were little changed. The retreat in oil removed the remaining energy-driven inflation concern that followed the Federal Reserve's Sept. 16 rate rise, while crypto remained one of the few markets with a bid.
