(2001)所提出的 Bound Testing檢定加密貨幣、穩定幣和解釋變數間是否存在長期共整合關係,同時利用誤差修正模型(Error Correction Model)來識別短期互動方向,最後分別探討COVID-19疫情前後彼此間關聯是否發生變化。實證結果發現,加密貨幣不管在長期下與利率、避險資產黃金,抑或是短期內與恐慌指數VIX的互動,都凸顯加密貨幣帶給投資組合的避險效益有限。然而在穩定幣上,除了可以提供交易者在加密貨幣市況不佳時暫避風頭,本文更發現穩定幣短期下能夠在熊市或市場情緒恐慌之際,吸引資金流入,甚至在疫情後與利率的連結產生轉變,被投資者視為避風港。不過,由於加密貨幣與穩定幣屬於新興領域,市場信心度受負面消息影響甚巨,購買者仍須時刻注意。
Since the emergence of cryptocurrency, its decentralized and unregulated features have attracted the interest of many investors, leading to a surge of research on the topic. Despite the low correlation or hedging ability of cryptocurrencies with traditional financial markets, their high volatility has often made investors cautious. To address this issue, stablecoins linked to assets with stable prices were introduced in 2014 to serve as a safe haven for cryptocurrency. After the outbreak of COVID-19, the injection of massive amounts of funds into the market by the US government`s quantitative easing policy and consecutive rate cuts pushed up the prices of cryptocurrencies, setting new historical highs one after another. But in March 2022, the Federal Reserve announced the resumption of interest rate hikes and balance sheet reduction to combat persistent inflation. This caused a sharp decline in the overall market capitalization of cryptocurrencies, and brought stablecoins back into the spotlight.Unlike previous literature, this paper compares both cryptocurrencies and stablecoins, examining their reactions to traditional financial markets, common trading assets, and different variables. The research method first confirms the stationarity of variable sequences using the unit root test, then combining the ARDL (Autoregressive Distributed Lag Model) model with the Bound Testing proposed by Pesaran and Shin (1999) and Pesaran et al. (2001) to investigate the existence of long-term cointegration relationships among cryptocurrencies, stablecoins, and explanatory variables. The Error Correction Model is used to identify short-term interactive directions, and the changes in their correlation before and after the COVID-19 pandemic are separately explored.Empirical results show that cryptocurrencies have limited hedging benefits for investment portfolios in the long run, regardless of their interactions with interest rates, hedge assets such as gold, or the short-term interaction with the VIX index. On the other hand, stablecoins not only provide traders with a safe haven during adverse cryptocurrency market conditions, but also attract capital inflows during bear markets or market panic in the short term. Moreover, the link between stablecoins and interest rates underwent a change after the pandemic, making them more appealing to investors as a safe haven. However, as cryptocurrencies and stablecoins are still emerging fields, their market confidence is highly affected by negative news, and buyers need to remain vigilant.參考文獻 Baur, D. G., & Hoang, L.
