European Central Bank — Trade weights (WTS)
The Trade Weights (WTS) dataset is an official time series published by the European Central Bank Data Portal as the WTS dataflow over the SDMX 2.1 REST API. It provides trade-weight data used in calculating effective exchange rates for euro area economic analysis. A single endpoint serves multiple formats, including XML (SDMX-ML), CSV (via ?format=csvdata), and JSON (via ?format=jsondata). Users can extract specific series using a key path combined with startPeriod, endPeriod, and lastNObservations filters. The same underlying series can also be browsed and charted interactively through the ECB Data Portal website, without requiring authentication for access.Trade weights (WTS) — official time series from the European Central Bank Data Portal, published as the WTS dataflow over SDMX 2.1 REST.
