European Central Bank — Financial market data - yield curve (YC)
This dataset provides euro area yield curve time series published by the European Central Bank as the YC dataflow, part of the ECB Data Portal. Data is delivered through an SDMX 2.1 REST endpoint offering XML (SDMX-ML), CSV, and JSON formats. Users can extract specific series using a key path combined with startPeriod, endPeriod, and lastNObservations filters, allowing targeted retrieval of yield curve observations without downloading the full dataset. The same series can also be browsed and charted interactively on the ECB Data Portal, making the dataset useful for financial market analysis and monetary policy research across the euro area.”}Financial market data - yield curve (YC) — official time series from the European Central Bank Data Portal, published as the YC dataflow over SDMX 2.1 REST. One endpoint serves XML (SDMX-ML), CSV (?format=csvdata) and JSON (?format=jsondata); extract exactly the series you need with a key path and startPeriod / endPeriod / lastNObservations filters.
