 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.

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.
