In this study, conducted by Marcin Włodarczyk and his colleagues, the cross-correlations between the cryptocurrency market and traditional financial markets are measured in the period from January 2020 to October 2022. The study focuses on the two most liquid and highest-capitalized cryptocurrencies, Bitcoin and Ethereum, along with instruments representing stock indices, Forex, and commodities. The aim of the research is to determine whether the cryptocurrency market still maintains its autonomy or if it has aligned with traditional financial markets at the expense of its independence. The researchers used a $q$-dependent detrended cross-correlation coefficient based on high-frequency 10-second data in a rolling window to examine dependence on various time scales, different fluctuation magnitudes, and different market periods. The results indicate that since the March 2020 Covid-19 panic, there is a strong indication that the dynamics of Bitcoin and Ethereum price changes are no longer independent but instead related to traditional financial markets. This coupling is especially evident in 2022 when Bitcoin and Ethereum's coupling to US tech stocks is observed during a market bear phase. Furthermore, cryptocurrencies have begun reacting to economic data such as Consumer Price Index readings similarly to traditional instruments. Such spontaneous coupling of previously independent degrees of freedom can be interpreted as a kind of phase transition resembling collective phenomena typical for complex systems. These results suggest that cryptocurrencies cannot be considered safe havens for financial investments. The authors note some limitations that may have influenced their conclusions; only two principal cryptocurrencies were studied (Bitcoin and Ethereum), which do not define the entire market. Additionally, they acknowledge that their analysis includes only a small fraction of available traditional financial instruments; however, they believe these choices are among the most observed and influential ones in global economics. Overall, this study brings strong indications that after twelve years of maturation processes, cryptocurrencies have become another part of global financial markets. While this direction may not align with early cryptocurrency creators' visions, it does allow investors to broaden their investment possibilities. As inter-market couplings may not last forever due to complexity allowing flexible reactions by systems to external perturbations and internal processes; future studies must continue investigating cross-market dependencies within cryptocurrency research while also considering energy consumption within this market.
There was a study about how cryptocurrency (like Bitcoin and Ethereum) is related to regular money markets. The researchers wanted to see if cryptocurrency is still independent or if it's becoming more like regular money. They used a special way of measuring this relationship over time. The results showed that since the COVID-19 pandemic started, cryptocurrency has become more connected to regular money markets. This means that they are not as different from each other as they used to be. It's important to keep studying this relationship in the future.
Definitions
- Cryptocurrency - digital or virtual currency that uses cryptography for security and operates independently of a central bank. 2. Market - a place where goods or services are bought and sold. 3. Independence - the state of being free from outside control or influence.
Cryptocurrency Market Coupling with Traditional Financial Markets: A Study
In a recent study conducted by Marcin Włodarczyk and his colleagues, the cross-correlations between the cryptocurrency market and traditional financial markets were measured in the period from January 2020 to October 2022. The researchers focused on two of the most liquid and highest-capitalized cryptocurrencies, Bitcoin and Ethereum, along with instruments representing stock indices, Forex, and commodities.
The Aim of the Research
The aim of this research was to determine whether or not the cryptocurrency market still maintains its autonomy or if it has aligned with traditional financial markets at the expense of its independence. To do this, they used a $q$-dependent detrended cross-correlation coefficient based on high-frequency 10-second data in a rolling window to examine dependence on various time scales, different fluctuation magnitudes, and different market periods.
The Results
The results indicate that since March 2020 when Covid-19 panic began spreading across global markets there is strong evidence that Bitcoin’s and Ethereum’s price changes are no longer independent but instead related to traditional financial markets. This coupling is especially evident during 2022 when Bitcoin and Ethereum's coupling to US tech stocks is observed during a bear phase. Furthermore, cryptocurrencies have begun reacting similarly to economic data such as Consumer Price Index readings as traditional instruments do.

Limitations
The authors note some limitations which may have influenced their conclusions; only two principal cryptocurrencies were studied (Bitcoin & Ethereum), which does not define the entire market. Additionally they acknowledge that their analysis includes only a small fraction of available traditional financial instruments; however they believe these choices are among the most observed & influential ones in global economics.
Conclusion
Overall this study brings strong indications that after twelve years of maturation processes cryptocurrencies have become another part of global financial markets. While this direction may not align with early cryptocurrency creators' visions it does allow investors to broaden their investment possibilities.
In this study the cross-correlations between the cryptocurrency market represented by the two most liquid and highest-capitalized cryptocurrencies: bitcoin and ethereum, on the one side, and the instruments representing the traditional financial markets: stock indices, Forex, commodities, on the other side, are measured in the period: January 2020--October 2022. Our purpose is to address the question whether the cryptocurrency market still preserves its autonomy with respect to the traditional financial markets or it has already aligned with them in expense of its independence. We are motivated by the fact that some previous related studies gave mixed results. By calculating the $q$-dependent detrended cross-correlation coefficient based on the high frequency 10 s data in the rolling window, the dependence on various time scales, different fluctuation magnitudes, and different market periods are examined. There is a strong indication that the dynamics of the bitcoin and ethereum price changes since the March 2020 Covid-19 panic is no longer independent. Instead, it is related to the dynamics of the traditional financial markets, which is especially evident now in 2022, when the bitcoin and ethereum coupling to the US tech stocks is observed during the market bear phase. It is also worth emphasizing that the cryptocurrencies have begun to react to the economic data such as the Consumer Price Index readings in a similar way as traditional instruments. Such a spontaneous coupling of the so far independent degrees of freedom can be interpreted as a kind of phase transition that resembles the collective phenomena typical for the complex systems. Our results indicate that the cryptocurrencies cannot be considered as a safe haven for the financial investments.
