According to Woofun AI, the S&P 500 index has once again touched an all-time high (ATH), yet Bitcoin has failed to follow suit in step with this strong macro market performance. This divergence between assets is not coincidental; historical experience deeply demonstrates that the single dimension of "rising risk appetite" alone cannot explain the current market divergence. The core contradiction lies in the essential difference in sensitivity to liquidity and interest rate environments across different assets.

On October 6, driven by both falling oil prices and declining U.S. Treasury bond yields, the S&P 500 index climbed strongly above 7,840 points, setting a new record. Data shows the index has broken through this key level, with the 10-year Treasury yield dropping about 2.1 basis points to 5.28%. Optimism about the artificial intelligence sector and the upcoming earnings season further pushed the index higher, while the recent strengthening and subsequent pullback of the U.S. dollar also boosted sentiment across various dollar-denominated markets. Although long-term borrowing costs remain elevated, with the 30-year Treasury yield approaching 5.66% on that day, this did not fully offset short-term positives — it merely failed to return the market to the low-yield environment needed for previous cryptocurrency rallies.

For Bitcoin, this record is more context than conclusion. Investors are increasing risk exposure in leading stocks, but the key question is whether lower yields and a weakening dollar can persist long enough to materially affect BTC. Our analysis points out that the dollar's role in Bitcoin's macro environment has a more sustained impact than several rounds of strong stock market performance. The new high in the S&P 500 is merely a data point, not an independent signal for BTC movement. For example, the August 2025 market should be viewed as a complete cycle; treating every new high as a trigger would be an exaggeration.

Woofun AI's compiled data shows that the current 10-year Treasury yield remains above 5%, far from the rate environment of the 2020–21 bull market, and the dollar's depreciation is merely a brief reaction after strengthening, with its long-term trend still unclear. Historical case reviews reveal enormous differences in BTC performance under different macro environments. In February 2020, when the S&P 500 set a record, Bitcoin was priced at around $9,600. Then the COVID-19 pandemic struck, investors turned to cash assets, and Bitcoin fell sharply in tandem with stocks — that record was actually a marker of the end of a market phase. In contrast, August 2020 was completely different: interest rates were low, central banks provided massive liquidity, and the dollar was depreciating. Although BTC did not rise in a straight line after the S&P 500 record, the subsequent months propelled it into the 2020–21 bull market cycle. The difference between February and August 2020 stems from the different market environments at the time the records were formed.

On January 3, 2022, the S&P 500 once again set a closing high, with Bitcoin priced at around $46,500. At that time, the market already expected the Federal Reserve to tighten monetary policy, bond yields were rising, and the cost of capital was increasing. Against the backdrop of rising rates, Bitcoin's rebound efforts ultimately ended in a larger decline, as investors reassessed the value of risk assets. The situation in January 2024 was different again: after the U.S. spot Bitcoin ETF (IBIT.US) began trading, Bitcoin initially pulled back due to early buyers taking profits and the market adapting to structural changes, then went on to set a new all-time high in March. This shows that even when the stock market belongs to the broader market as a whole, cryptocurrency-specific catalysts can dominate BTC's direction.

Comprehensive assessment suggests a historical pattern: when the stock market is strong and financial conditions are loose, or when there is strong crypto demand, Bitcoin tends to perform well; once a liquidity shock or policy tightening occurs, BTC faces difficulties. The common ground between the current situation and favorable environments is that financial stress has eased somewhat — falling oil prices reduce inflation concerns, and lower yields and a weakening dollar give stocks room to rise. However, the 10-year Treasury yield remains above 5%, far from the 2020–21 rate environment. Bitcoin's own momentum is equally critical; sustained spot buying signals are fundamentally different from moves driven primarily by futures leverage or short position liquidation, and its own market data is at least as important as S&P 500 performance.

The new S&P 500 high reflects stock investors' willingness to take on more risk as yield and dollar pressures ease. Previous record periods show that in the face of the same market events, Bitcoin may rally, lag, or decline. Future changes in yields, the dollar exchange rate, and Bitcoin's own demand will determine whether the trend is driven by the stock market or evolves into a broader shift in overall risk appetite.
