| Abstract: | Transactions denominated in U.S. dollars flow around the clock and around the globe, filling the pipelines that support commerce. On a typical day, more than $14 trillion of dollar-denominated payments is routed through the banking system. Critical to a well-functioning economy are the timing and smooth flow of dollars for large-value transactions and the infrastructure that enables that dollar flow. This financial market infrastructure provides essential economic services??plumbing? for the economy?and is made up of a variety of entities. In this post, we describe this financial market infrastructure, providing a simple map of its main entities and describing the flow of U.S. dollar payments among these entities. A more detailed study of intraday liquidity flows has been released by the Payments Risk Committee. |

| Abstract: | In time-series analysis, the term "lead-lag effect" is used to describe a delayed effect on a given time series caused by another time series. lead-lag effects are ubiquitous in practice and are specifically critical in formulating investment strategies in high-frequency trading. At present, there are three major challenges in analyzing the lead-lag effects. First, in practical applications, not all time series are observed synchronously. Second, the size of the relevant dataset and rate of change of the environment is increasingly faster, and it is becoming more difficult to complete the computation within a particular time limit. Third, some lead-lag effects are time-varying and only last for a short period, and their delay lengths are often affected by external factors. In this paper, we propose NAPLES (Negative And Positive lead-lag EStimator), a new statistical measure that resolves all these problems. Through experiments on artificial and real datasets, we demonstrate that NAPLES has a strong correlation with the actual lead-lag effects, including those triggered by significant macroeconomic announcements. |
