BlockBeats News, August 25th. Bitcoin surged to $81,265 on Tuesday before falling back, dropping to as low as $78,111 and once again failing to hold above the $80,000 level. Gold also weakened in tandem, with spot gold dropping nearly 2% to $4,605 per ounce, after earlier rising to $4,697, hitting a new high since mid-May.Market trends show that the retreat in U.S. bond yields did not continue to drive up Bitcoin and gold, but instead led to a divergence where U.S. stocks strengthened while cryptocurrencies and gold weakened. The S&P 500 rose by 0.2%, the Nasdaq Composite rose by 0.5%; at the same time, the U.S. 30-year Treasury yield fell below 5.2%, approaching the low since August 7th.Analysis believes that the recent changes in U.S. bond yields remain a key driving factor in the crypto market. The U.S. Treasury Department previously expanded the scale of long-term Treasury repurchases to alleviate the upward pressure on long-end yields, but in the current inflation environment, the Fed's room for interest rate cuts remains limited.Currently, the market expects a 61.9% probability that the Fed will keep rates unchanged in September. In the short term, the market focus is shifting from U.S. bonds to U.S. July PCE inflation data and the Jackson Hole Symposium. Nvidia will release its earnings report after Wednesday's market close, which could also become a new catalyst for volatility in risk assets.
