This paper analyzes the stability of stablecoins and proposes a framework to test for absolute and relative stability of stablecoins. Based on high-frequency data, we find strong evidence of excess price variations. While Bitcoin is a likely source of this excess volatility because stablecoin returns, volatility and volumes are highly correlated with corresponding Bitcoin time-series, we also demonstrate through a quasi-natural experiment that stablecoins increase the trading volume of Bitcoin. The findings suggest stablecoins play a key role in cryptocurrency markets. GRAPHICAL ABSTRACT

Buy-now-pay-later (BNPL) arrangements have rapidly emerged as a short-term debt option, and like other innovative and disruptive Fintech, challenge existing regulation. BNPL arrangements avoided prescribed ‘responsible lending’ legislative obligations, which applied to similar short-term credit products. Instead, BNPL relies on ‘responsible spending’ in providing a potentially cheaper option than alternatives such as credit cards. We describe the interplay of regulation and responsibility with BNPL. A survey investigates whether a key demographic (young adults) have an appetite or skill for responsible use. We analyse the preference for BNPL relative to credit cards and the role of financial literacy and traits including propensity to plan and save. The findings suggest that financial literacy reduces perceived BNPL benefits and that lower financial literacy is associated with more benefits and less risks.

Bitcoin is defined as digital money within a decentralized peer-to-peer payment network. It is a hybrid between precious metals with intrinsic value and fiat cu

The Bitcoin futures market has grown rapidly since its 2017 introduction. Along with enabling institutional traders to access a regulated cryptocurrency product, futures provide a means to improve market efficiency by shorting Bitcoin. We examine trading behavior in Bitcoin futures utilizing the Commodity Futures Trading Commission Commitment of Traders report. Leveraged money traders tend to hold the largest positions, be net short, and their trading behavior plays a key role in the Bitcoin futures market. Our empirical results show that leveraged money traders display market timing ability, largely by adjusting their short positions. It seems that other trader types follow this “smart money” in adjusting their own positions in subsequent periods. We also demonstrate that it is possible to construct profitable trading strategies based on observed variations in leveraged money positions.
