Bitcoin correlation regimes across equities and gold
Daily, weekly, rolling-window, and lead-lag readings from late April 2013 through March 2020 show when bitcoin’s link to the S&P 500 tightened, when gold and yields failed as a stable offset, and when shared selloffs undercut a safe-haven-claim.
- On daily prices from late April 2013 through March 2020, bitcoin’s Pearson correlation with the S&P 500 was 0.85, while gold and the dollar-yuan pair each printed 0.52.
- Calendar-year bitcoin-equity correlations changed sign more than once, and shared selloffs in late 2018 and March 2020 were used to reject a sample-period safe-haven-claim.
- Weekly return correlations were weaker than price-level correlations, while a late-sample three-month window showed a 0.84 daily equity link and a sharper inverse link with the VIX.
- The suggested intermarket-analysis use was to track the currently strongest related market, keep a trend model aligned with that market’s direction, and treat the measured links as average tendencies that can reverse.
Twelve markets and several windows
The study measured bitcoin’s links to twelve related markets across sub-periods, using contemporaneous, lead-lag, and intradaily windows to see which relationships were strongest. Intermarket-analysis placed bitcoin next to related prices, volatility, yields, and currency pairs rather than treating the name as an isolated series. Correlation-analysis then checked how those series moved together across fixed, rolling, and shifted windows so a diversification story could be tested instead of assumed.
The full-sample daily map
On daily prices from late April 2013 through March 2020, bitcoin’s Pearson correlation with the S&P 500 was 0.85, while gold and the dollar-yuan pair each printed 0.52. Those scores describe an average tendency across the whole stretch. They do not fix the next market-regime.
Sign flips, crash windows, and broken linear clouds
Calendar-year bitcoin-equity correlations changed sign more than once, which is why a rolling-window matters: the moving lookback shows whether a link is stable or only appears in one calendar stretch or stress episode. Near the end of the sample, the three-month daily reading versus the S&P 500 rose to 0.84 after weaker one- and two-year windows.
Shared selloffs in late 2018 and March 2020, when bitcoin fell in tandem with global equities, were used to reject the sample-period claim that bitcoin behaved as an equity safe haven. A safe-haven-claim is treated here as a hypothesis to test, not a standing label.
A seven-year weekly scatter of bitcoin against the S&P 500 showed an r-squared of 0.72, but the linear cloud broke down below 2,000 and above 10,000. A March 2020 15-minute futures overlay still tracked the equity index, with bitcoin lagging peaks by about 45 minutes.
Gold, yields, and lead-lag
Gold’s multiyear daily correlation with bitcoin was only moderately positive and flipped negative in several yearly windows. The seven-year link to 10-year Treasury yields was effectively zero.
Over the two years ending March 2020, weekly-return lead-lag scores were higher when bitcoin was treated as the leading series versus gold and the S&P 500. Shifting one series in time tested whether it typically moved before or after the other market. Bitcoin’s own autocorrelation stayed elevated through three weekly lags, a mark of trend persistence in its recent changes.
Weaker return links and a larger typical move
Correlations of weekly returns were weaker than price-level correlations across the board. That price-versus-return-correlation gap appears because percentage changes strip out shared trends. The three-month window into early 2020 showed a sharp rise in the inverse link with the VIX.
In the 2013-2020 daily sample, bitcoin’s typical absolute percent move was about five times that of the S&P 500 or gold, and the 95th percentile daily change was 9.91 percent.
Aligning a trend model with the strongest related market
The suggested intermarket use was to track the currently strongest related market and keep a trend model aligned with that market’s direction, while treating the measured links as average tendencies that can reverse.
