Argentina's benchmark Merval index fell 0.89% to 3,248,428 on Tuesday, marking a second consecutive session of weakness as investor optimism regarding an MSCI upgrade continued to dissipate.

The pullback represents a retreat from recent record highs, signaling that market participants are recalibrating expectations for foreign inflows tied to global index inclusion.

The decline in equity sentiment was not mirrored in the currency market, where the Argentine peso held steady against the dollar.

This divergence suggests that while equity valuations are sensitive to the fading upgrade narrative, the local currency remains supported by broader macroeconomic stability or central bank intervention, decoupling the two asset classes in the short term.

The Merval's retreat comes amid a broader backdrop of risk-off sentiment in emerging markets.

Selling pressure has intensified in US equity markets, with large-cap technology stocks leading declines, while major indices across the Gulf also closed lower.
