This paper investigated the relationship between cryptocurrencies and emerging stock market indices using fractional integration and co-integration technique. Particularly, fractional integration is applied to examine stochastic properties of individual assets and fractional cointegration to analyse bivariate connectedness. Our findings unveil the absence of mean reversion in majority cases which indicates high persistence in series. Furthermore, bivariate analysis reveals disconnection between cryptocurrencies prices and stock indices. Surprisingly, a different picture emerges on using conditional volatility instead of prices. Like, conditional volatility-based estimation uncovers evidence of mean reversion in univariate analysis as expected. There is some evidence of cointegration on volatility grounds between cryptocurrencies and emerging stock market indices. Our findings implies that investment decision regarding digital currencies should be taken cautiously. As cryptocurrencies are extremely volatile with high degree of persistence which can make them counterproductive.

Exchange rate volatility has emerged as a significant challenge for Asian emerging markets since the adoption of the liberalization process. This study examines the influence of central bank transparency on exchange rate volatility using a sample of ten important Asian emerging markets. The study uses a fixed effect regression model covering the Asian financial crisis, global financial crisis, banking crisis, and taper tantrum episodes. Results show that an increase in central bank transparency has a stabilizing effect on exchange rate volatility, and this effect remains even after controlling for various internal and external factors. The uncertainty of US monetary policy increases exchange rate volatility, while US economic policy uncertainty contributes only during the global financial crisis. Interestingly, central bank transparency buffers the effects of the global financial crisis, indicating that it plays a facilitating role in maintaining financial stability. Studies that examine the role of central bank transparency in curbing exchange rate volatility, which is a crucial issue in these markets, are rare in emerging markets’ context. This research offers interesting findings by using a variety of robustness checks.
