The Bank of Japan is expected to maintain its pledge to keep raising interest rates at next week's policy meeting, while emphasizing that any additional moves will depend on how the economy responds to each hike, BlockBeats reported on December 12, citing three unnamed sources. BOJ Governor Kazuo Ueda has effectively signaled a December rate increase, and markets have almost fully priced in a move from 0.5% to 0.75%, with focus now on how far the central bank can lift rates toward a neutral level. The sources said the BOJ may internally revise its estimate of how far the current policy rate is from the neutral rate but will avoid using that estimate as its main communication tool for the future tightening path because of forecasting challenges. Instead, the BOJ will explain that upcoming decisions will be guided by how past hikes have affected bank lending, corporate funding conditions and other economic activity, with one source saying Japan's very low real interest rates allow the central bank to proceed with rate hikes in several stages, a view shared by the other two sources.

A wallet described as a "BTC OG insider whale" transferred 5,152 BTC, valued at about $476.68 million, to a new address on December 12, BlockBeats reported citing Onchain Lens. The on-chain move was detected roughly five minutes after execution, and all funds were consolidated into the single newly generated wallet.

BTC OG insider whale continued to add to a 5x leveraged ETH long position in the past 30 minutes, taking the holding to 151,094.5 ETH (约 4.92 亿美元) on December 12, according to Hyperinsight. The average entry price is 3185.05 美元, and the unrealized profit per coin is 1050 万美元, Hyperinsight said.

On December 12, Anza's Vice President of Core Engineering Brennan Watt said at the Solana Breakpoint conference that proposal SIMD-0389 is designed to reduce Solana account creation rent by 10x, with potential to expand the cut to 100x, BlockBeats reported. In the Solana network, Account Rent is a storage fee required to keep an account's data permanently on-chain. Anza's analysis of the safety slowdown mechanism, which was discussed recently at SolanaConf, indicates the change could unlock broader adoption by reclaiming hundreds of millions of dormant SOL while maintaining network security.

The U.S. dollar weakened on December 8 as markets looked ahead to this week's Federal Reserve policy decision, which many expect will again result in a rate cut, BlockBeats reported citing Jin10. Deutsche Bank analysts wrote in a report that the Fed is likely to announce on Wednesday its third and final 25-basis-point rate cut of 2025, adding that the decision may not be unanimous. The analysts said Chair Jerome Powell's press conference and accompanying statement will be key, and they expect him to signal a short-term pause in easing by stressing that the threshold for further cuts in early 2026 is very high.
