The Impact of Financial Innovation on the Stability of the Financial System: An Empirical Analysis Using Virtual Currency as an Example

The impact of financial innovation on the stability of the financial system is a subject of extensive research and interest in both academic and market circles. This study focuses on virtual currency, particularly Bitcoin, as a representative of financial innovation to empirically analyze its influence on the financial system's stability. Virtual currencies, including Bitcoin, are digital assets created and exchanged using cryptography and distributed ledger technology, providing decentralized and secure transactions. Financial innovation, driven by technological advances and market demands, encompasses various emerging financial products and technologies, such as blockchain, smart contracts, and digital assets, with the potential to enhance financial efficiency and inclusion. This research explores the relationship between Bitcoin price volatility and risk, identifies price bubbles, and studies its interaction with traditional financial assets. The GARCH(1,1) model is employed to analyze the conditional variance dynamics, and the results suggest that past prices and returns significantly influence current conditional variance. However, residual analysis indicates no significant autocorrelation or heteroscedasticity in the residual sequence. These findings offer insights into Bitcoin's impact on financial market stability, highlighting its potential as an additional hedging tool in portfolio management and market analysis. Nonetheless, the decentralized and minimally regulated nature of virtual currencies poses risks that require policy attention to maintain financial stability. Despite providing valuable insights, this study has limitations, such as not considering the impact of other economic indicators. Future research should delve into additional factors and mechanisms to comprehensively assess virtual currencies' influence on financial system stability. Policymakers are urged to implement relevant measures to mitigate the excessive impact of financial innovation products on domestic financial markets.
