Decentralized dealers? Examining DEX liquidity provision (BIS)
The Bank for International Settlements (BIS) published a paper that explores the role of participants in providing liquidity on decentralized exchanges (DEXs). DEXes allow participants to buy and sell assets without the need for intermediaries, in theory democratizing liquidity provision. However, using data from the largest DEX (Uniswap V3), it shows that liquidity provision, rather than being the purview of a diffused set of market participants, is confined predominantly to a small group of sophisticated ones. These participants submit orders that mimic bids and asks and are able to extract significantly higher profits compared to their unsophisticated counterparts. They also exhibit considerable skill, extracting higher profits during periods of high volatility by capturing a higher share of trading without incurring additional adverse selection.

The proof-of-stake protocol and run risk (OFR)
The U.S. Treasury Office of Financial Research (OFR) published a paper that examines the scenarios that can increase run risk of crypto-assets, such as Ethereum (ETH), that use proof-of-stake (POW) protocols to validate transactions. It finds that while proof-of-work (POW) protocols are more energy intensive and less scalable, POS requires more capital, and a significant drop in a POS-based crypto-asset price may cause validators to exit their investments. Their exit may impair the tradability of the crypto asset, which in turn may cause more validators to exit, resembling a bank run. In the case of Ethereum, such an event would disrupt activity relying on the Ethereum network, including many crypto firms and DeFi networks. The authors also show that the use of margin only exacerbates this run risk during price declines. If a price decline is steep enough to cause a margin call for investors, those investors must either post additional collateral or sell crypto assets, which could further depress prices.

Retail fast payment systems as a catalyst for digital finance (BIS)
The BIS published a paper that sheds light on how fast payment systems (FPSs) influence the diffusion of digital finance apps, based on a rich dataset on app downloads and use for 86,163 apps in 95 countries over 2012–22. It identifies various mechanisms through which FPS drive finance app adoption, like stimulating competition and innovation in payments, fostering digital finance adoption via learning effects and expanding access to financial services, particularly in emerging market and developing economies (EMDEs) and low income countries (LICs). This effect is particularly evident for apps by technological disrupters, such as fintechs or big techs, relative to those of incumbent financial institutions. Finally, we identify some characteristics of FPS that further amplify digital finance adoption such as the active role of the central bank, open membership and real-time settlement.
