Crypto–Equity Correlation and Implied Versus Realized Volatility
Summary
This commentary compares Bitcoin and Ether market behavior with US equities and gold. It uses rolling 30-day return correlations to describe crypto’s renewed relationship with equities and gold after correlations had been near zero in July. It also compares realized volatility based on 30-day daily returns with option-implied volatility estimates for Bitcoin and Ether and the VIX as an equity volatility measure.
The commentary reports that crypto and equities saw higher realized volatility near the end of August, while implied volatility did not rise in parallel. As a result, the implied-to-realized volatility ratio fell for each asset; equities nevertheless retained a higher ratio than crypto. The figures are descriptive and cover a particular period, so they do not establish that these relationships will persist or provide a trading rule. The text does not explain the precise calculation details or show numerical series beyond the reported correlation coefficient, making the findings useful as a market snapshot rather than a reproducible test.
Key ideas
- Crypto return correlations with US equities and gold rose from near-zero levels reported for July.
- The commentary measures correlation over rolling 30-day windows.
- Bitcoin and Ether realized volatility had been trending down before rising near the end of August.
- Implied volatility changed less than realized volatility during that late-August increase.
- The implied-to-realized volatility ratio remained higher for equities than for crypto in the period discussed.
