Stablecoins are rapidly expanding as money-like assets for payments, trading, settlement, and cross-border transfer. In response, policymakers are moving quickly to develop new regulatory frameworks to safeguard the monetary and financial system. This article develops a forward-looking,...

This paper examines how digital financial platform engagement influences financial inclusion in the Philippines and explores how financial institutions are deploying artificial intelligence (AI) in enhancing these platforms. It combines nationally representative data from the World Bank Global...

Around three quarters of Bitcoin transactions take place off-chain. Despite their significance, the vast majority of the empirical literature on cryptocurrencies focuses on on-chain transactions. This paper presents one of the first analysis of both on- and off-chain demand- and supply-side...

Programmability is at the heart of ongoing work on the future of money and payments by central banks around the world. Despite its potential, there is growing concern that programmability conflicts with the provision of "good" money. This paper overviews key principles of "good" money and argues...

Cryptocurrencies play a central role in modern financial markets; however, geopolitical tensions and environmental concerns raise critical questions about their stability and informational efficiency. This study distinguishes between green cryptocurrencies (GCs), based on low-energy validation...

This SAFE White Paper presents a structured economic framework for assessing asset-backed stablecoins in their capacity as privately issued, fiscally anchored monetary instruments. Specifically, we evaluate the implications of stablecoins for financial intermediation, sovereign debt markets, and...

We study how the type of money used in blockchain-based trade affects interest rates, investment, and welfare. Stablecoins in our model are backed by safe assets, while banks issue deposits (both traditional and tokenized) to fund a portfolio of safe and risky assets. Deposit insurance creates a...

We propose a theory of stablecoin disintermediation, whereby stablecoins not only erode banks' deposit franchises but also transmit liquidity stress to the banking system. Using transaction-level data linking onchain transactions to wholesale interbank payments, we document the first evidence of...

This study examines the use of Filtered Historical Simulation (FHS) to estimate tail risk in cryptocurrency markets for the optimization of robustness in this area under model misspecification. An ARMA-GARCH model is employed on the daily returns on Binance Coin and Litecoin in order to compare...

This paper investigates the dependence structure between returns and trading volumes for five major cryptocurrencies: Bitcoin, Cardano, Ethereum, Litecoin, and Ripple. Using a copula-based framework, we focus on a mixture of the Joe copula and its 90-degree rotation to capture asymmetric...

In this paper, we propose a novel optimization model for portfolio selection that integrates the classical mean-variance criterion with a second-order Tsallis entropy term. This approach enables a trade-off between expected return, risk, and diversification, extending Markowitz's theory to...

This study investigates the return propagation dynamics between cryptocurrencies and emerging market sectoral indices (EMSI), focusing on portfolio impact from Bitcoin, Ethereum, and two gold-backed cryptocurrencies (PAXG and X8X). Using data from 2019 to 2024, we apply a novel DCC-GARCH-based...
