Bitcoin Mining and Native Inventory Market Efficiency Correlations
Crypto is an uncorrelated asset class, in response to its proponents, and as such must contribute to portfolio diversification. Nonetheless, research has shown that this claim hasn’t held up particularly well.
We examined the connection between the place bitcoin mining was carried out and the way the efficiency of the native fairness markets correlated with bitcoin costs and located that in the US particularly, the efficiency of the S&P 500 and bitcoin costs have exhibited a optimistic correlation during the last 5 years.
As a result of the US and China are the place most bitcoin mining has been carried out during the last 5 years, we used the S&P 500, Cling Seng, and Shanghai Composite indices as our regional proxies. We calculated the rolling nine-month correlation between bitcoin returns and every of the three indices utilizing weekly knowledge. We then in contrast that with the bitcoin hash price by nation from September 2019—which is way back to dependable information go—to January 2022.The bitcoin hash price measures the computational energy of the bitcoin blockchain and is a proxy for a way a lot bitcoin mining is being executed.
Previous to November 2020, China accounted for greater than 60% of bitcoin mining. However fast-forward to November 2021 and China’s share had plunged to about 15% in response to authorities steps to cut back bitcoin mining. Over the identical time interval, the US climbed from representing about 10% of worldwide bitcoin mining to greater than 35%.

Bitcoin Mining Distribution by Nation, 2019 to 2022
These traits make the November 2020 to November 2021 time-frame a wonderful window into how bitcoin-prices-to-index correlations alter as bitcoin mining ebbs and flows. We discovered that as US crypto mining spiked between November 2020 and November 2021, bitcoin’s correlation with the S&P 500 rose to 0.39 from 0.28. However as crypto mining plummeted in China throughout the identical interval, bitcoin’s correlation with the 2 Chinese language indices fell additionally. The Cling Seng’s and Shanghai Composite’s bitcoin correlation declined to -0.14 from 0.21 and to -0.44 from 0.09, respectively.
Bitcoin Correlations with Fairness Indices
| November 2020 | November 2021 | |
| S&P 500 | 0.283 | 0.386 |
| Cling Seng | 0.213 | –0.138 |
| Shanghai Composite | 0.085 | –0.437 |
The outcomes counsel the extra bitcoin is mined in a selected nation, the larger the correlation between the cryptocurrency and native fairness markets. As bitcoin mining declines in a area, the correlation between bitcoin and native inventory markets subsides as effectively.
Relating to annual correlations between bitcoin costs and the indices in query, our speculation holds up there too. The extra bitcoin mining in a locale, the larger the correlation between the worth of bitcoin and native inventory markets. This relationship was strongest with the S&P 500 and Shanghai Composite and fewer so with the Cling Seng over the complete time interval.
Annual Correlations: Bitcoin and Fairness Indices
| 2016 | 2017 | 2018 | 2019 | 2020 | 2021 | 2022 | |
| S&P 500 | –0.174 | –0.119 | –0.045 | 0.064 | 0.155 | 0.186 | 0.747 |
| Cling Seng | –0.289 | –0.378 | 0.010 | 0.011 | 0.148 | –0.190 | 0.400 |
| Shanghai Composite | 0.014 | 0.253 | 0.096 | 0.122 | 0.169 | –0.390 | –0.040 |
In whole, our outcomes point out that the place bitcoin is mined might have an effect on the way it strikes and which inventory indices it strikes with. And this impacts what kind of diversification advantages bitcoin might or might not carry to a portfolio.
