Factors leading to this decline:

1. The Federal Reserve's downward revision of data has raised questions about its authenticity, causing panic sell-offs in the U.S. stock and cryptocurrency markets, resulting in asset price declines.

2. Trump has once again criticized the Federal Reserve for data falsification, escalating tensions between the government and the Federal Reserve, raising concerns about its independence and policy fairness (he has long criticized the Federal Reserve's monetary policy and called for interest rate cuts).

3. Federal Reserve Governor Quarles' early resignation provides an opportunity for Trump to appoint candidates that align with his ideology, impacting the future policies and internal dynamics of the Federal Reserve.

4. The market bets on a 89.8% probability of an interest rate cut in September. While interest rate cuts are favorable in the long term, short-term concerns over data and macroeconomic uncertainty have led to panic selling in the market, and asset prices may continue to fall, with the extent of the decline depending on multiple subsequent factors.
