Bitcoin climbed more than 2% to $81,411 ahead of the Federal Reserve's interest rate decision, with Ether at $2,490 and other major altcoins including Solana and XRP also gaining over 2%. The rally comes as the 10-year Treasury yield pulled back to 5%, a 36-basis-point drop since October 7, easing financial conditions and boosting risk appetite in crypto markets. Fed Chair Jerome Powell's comments on inflation will be closely watched, with consumer price inflation exceeding expectations for two consecutive months and oil prices near $100. Any acknowledgment of easing financial conditions could influence rate hike bets, while elevated energy prices limit room for growth-over-inflation bias from the central bank. In other developments, Google is set to preview its new Multi-Party Compute security system designed to help banks and financial institutions safeguard cryptocurrencies and tokenized assets amid growing AI threats. Meanwhile, Bitcoin treasury company Datavault AI plunged nearly 50% after revealing it could not access its bitcoin held on exchange Biconomy since June and would need to restate financial results.
