We investigate intraday hedging and the safe haven role of Bitcoin for stocks, currencies, and oil. The hedge concept depends on non-correlation or negative interaction, on average, while the safe haven concept depends on non-correlation or negative correlation in times of market turmoil. We look at Bitcoin’s ability to be a hedge or safe haven asset with standard financial assets by considering a short investment horizon using high frequency data. Accordingly, we propose a new measure, the q-detrending moving average cross-correlation coefficient, to characterise intraday market interdependence between Bitcoin and these assets during medium and extreme movements. During medium fluctuations, Bitcoin is a weak hedge against currencies, oil, and stocks. During high fluctuations, we find a negative relationship between Bitcoin and oil, meaning Bitcoin can serve as a safe haven against extreme down movements in this market. However, Bitcoin is a weak safe haven asset for the other two markets.
