Argentina's informal dollar rate, known as the blue dollar, traded at a narrow premium to the official exchange rate on Wednesday, reflecting a continued compression of the parallel market spread.
The official rate stood at 1,520 pesos for sale, while the blue dollar was quoted at 1,570 pesos for sale, according to local market data.
This minimal gap indicates that market participants are increasingly relying on the official channel, reducing the arbitrage opportunities that have historically driven demand for the informal currency.
The convergence of the two rates suggests that recent monetary policy measures and capital controls are having a stabilizing effect on the peso.
Traders have been cautious, with the US dollar index holding firm at a one-month high of 101.45, which typically exerts downward pressure on emerging market currencies.
However, the Argentine peso has shown resilience, with the blue dollar failing to break above the 1,570 level despite broader greenback strength.
