摘要

为应对 2007-2009 年全球金融危机，到目前为止，大多数金融交易都必须通过中央交易对手方进行清算，并采用动态保证金设定机制。高额追加保证金可以降低动荡市场中的交易对手风险，但同时也会增加流动性风险，加剧系统性风险。在本文中，我们构建了一个理论模型来应对这一挑战，并推导出一个最优保证金设置政策，将其视为一个随机控制问题。我们的分析表明，适应性反周期方法优于纯粹的风险敏感策略，主要是通过最大限度地减少清算机构的预期损失。

Dynamic margin optimization

In response to the Global Financial Crisis of 2007–2009, by now, most of the financial transactions must be cleared through central counterparties operating a dynamic margin setting mechanism. High margin calls can reduce counterparty risk in a turbulent market, but at the same time, increase liquidity risk and escalate systemic risk. In this paper, we construct a theoretical model to address this challenge, deriving an optimal margin setting policy framed as a stochastic control problem. Our analysis reveals that an adaptive, countercyclical approach is superior to a purely risk-sensitive strategy, primarily by minimizing the expected loss for the clearing institution.
