Masamichi Adachi, Chief Japan Economist at UBS Global Research, commented that it seems justified for the Bank of Japan to raise interest rates in the coming months. He stated that Japan's real interest rates are negative, making the financial environment very loose. The inflation dynamics seem to support the view that the central bank should reduce its loose policy, as long-term inflation expectations are expected to continue to rise towards 2.0%. He also expects the government to seek fiscal expansion, which could mean higher inflation pressures. UBS expects the Bank of Japan to raise its policy rate by 25 basis points in January, but does not rule out the possibility of a rate hike in December. (FXStreet)

Osamu Takashima, chief exchange rate strategist at Citibank, said that Sanae Takahashi claims to be the successor of former Prime Minister Shinzo Abe. However, there are too many differences between 10 years ago and now. Ten years ago, Japan faced pressure from deflation and had a strong exchange rate. However, now Japan is facing issues of inflation and a weak exchange rate. Therefore, the situation is completely opposite to 10 years ago. Especially in terms of the Bank of Japan's monetary policy, I do not think she will pressure the Bank of Japan to refrain from raising interest rates. The issues in the Japanese economy are inflation and a weak yen, both of which are unwelcome among the Japanese people. Therefore, if she exerts political pressure on the Bank of Japan and the yen further depreciates, inflation will worsen. She may lose the support of the Japanese people. For her, this would be an extremely risky game. 

On October 21st, according to 4E observations, Federal Reserve Board member Michael Barr warned that the newly passed GENIUS Act may allow stablecoins to use Bitcoin as a reserve asset, thereby weakening their stability. Barr pointed out that although the Act does not directly support Bitcoin reserves, any exchange medium adopted by foreign governments or considered a qualified asset could potentially make El Salvador's case a loophole.

 during the Asian trading session, US Treasury yields fell slightly, with the 10-year Treasury yield falling below 4%. Pepperstone analyst Michael Brown stated in a report, "I find it difficult to prove that the two-year (US Treasury yield) will be significantly below 3.50%, and the ten-year (US Treasury yield) will be significantly below 4.00%, because the performance of the United States is better than other countries, inflation continues to rise, and overall risk appetite is positive." He said that without major, potentially unexpected macroeconomic downside risks, the expected room for further increase in US Treasury yields will weaken, especially for long-term bonds.

 according to on-chain analyst @ai_9684xtpa monitoring, SpaceX transferred $268 million worth of BTC again after three months. Among them, 1187 BTC have been transferred to address bc1qq...4sduw, and 1208 BTC have been transferred to address bc1qj7...6kqef. Currently, both receiving addresses have not been transferred or sold. However, it is worth noting that in July, SpaceX's sudden transfer was marked by Arkham as a Coinbase Prime Custody address, so this may just be wallet management.

On October 21st, Matrixport shared the following market views: The 21-week moving average has once again become a key observation point for the trend of Bitcoin. This level has always been seen as an important dividing line for bull and bear conversions: when the price is above it, it often means the market is shifting from bearish to bullish; while breaking below it usually indicates that the market is entering a correction phase. If Bitcoin fails to regain this level for a long time, the current consolidation trend may further evolve into a deeper pullback. The current pullback magnitude is still relatively mild, and in the context of the widespread expectation that the Federal Reserve will continue to cut interest rates, the overall trend may remain manageable unless there is a clear weakening of the US economy. From historical experience, the ideal entry point often occurs when Bitcoin briefly falls below this moving average, then rises back above it and maintains it for a long time. Until this signal appears, investors should remain cautious.
