European Central Bank — Securities Settlement Statistics (SST)
Securities Settlement Statistics (SST) is an official dataset published by the European Central Bank via its Data Portal, covering securities settlement activity across the euro area or EU. It is distributed as the SST dataflow through the SDMX 2.1 REST API, with a single endpoint serving XML (SDMX-ML), CSV, and JSON formats. Users can extract specific series using a key path together with startPeriod, endPeriod, or lastNObservations filters. The same series can also be browsed and charted interactively on the ECB Data Portal, making the dataset useful for economic and financial market analysis.Securities Settlement Statistics (SST) — official time series from the European Central Bank Data Portal, published as the SST dataflow over SDMX 2.1 REST.
