How this daily figure is produced
ETCurrency samples Argentina's USD/ARS parallel market throughout the day from peer-to-peer stablecoin order books and, where available, community submissions. Each sample is filtered for outliers and aggregated into a single buy and sell quote; the figures above are the first, highest, lowest and last of those aggregated quotes for Sep 18, 2026 (UTC).
USDT peer-to-peer prices closely track cash dollar prices in most parallel markets but are not identical to them: payment-method fees, merchant margins and local demand for stablecoins can all add a few tenths of a percent.
