Analysis of DeFi Oracles Staff discussion paper 2024-10 Xun Deng, Sidi Mohamed Beillahi, Cyrus Minwalla, Han Du, Andreas Veneris, Fan Long Oracles are constructs used in decentralized finance to price assets relative to each other. However, oracles contain defects that could lead to manipulation attacks. Such attacks exploit pricing models embedded within oracles to defraud creators and users. We automatically verify defects, which if mitigated, improves the security of digital currency.

Procyclicality in Central Counterparty Margin Models: A Conceptual Tool Kit and the Key Parameters Staff discussion paper 2023-34 Alper Odabasioglu Regulators need to provide effective procyclicality guidance, and central counterparties must design and calibrate their margin systems and procyclicality frameworks appropriately. To serve these needs, we provide a novel conceptual tool kit. Further, we highlight that the focus should be on the key margin system parameters in determining procyclicality.
