Peso Strain and Merval Slump Reveal Argentina’s Underlying Struggles
Argentina’s Central Bank fixed the official USD/ARS rate at 1,339.53 on September 25, yet traders paid around 1,400 pesos in the parallel market.
This gap reflects deep dollar scarcity and sustained demand outside official channels. Global liquidity tightened as the U.S. Dollar Index hovered at 98.36, pushing emerging markets into risk-off mode.
The S&P Merval plunged 4.1 percent to close at 1,767,848 points, driven by heavy peso sales by the Central Bank and ongoing doubts over reserve adequacy.
Daily trading volume climbed above its 20-day average, confirming the strength of the sell-off. On the daily chart, the index traded below its 50- and 200-day moving averages, and the MACD remained negative, signaling clear downward momentum.
The RSI rested near 41, while narrowing Bollinger Bands pointed to reduced volatility after recent wild swings. Behind these figures lies a story of political and fiscal uncertainty.

Argentina prepares for midterm elections on October 26 amid rising public debt and sluggish tax revenues. Last week’s U.S. Treasury announcement of a conditional $20 billion swap line offered brief relief but failed to solve the structural shortage of dollars.
Grain exporters, once key providers of dollar inflows, now face delayed farm-tax reform payments, further tightening the supply of hard currency.
Shorter-term charts painted a similar picture. On the four-hour timeframe, the Merval tested support at 1,666,883 points and remained below the Ichimoku cloud, highlighting persistent resistance overhead.
The MACD histogram shrank toward zero, suggesting the downtrend might pause, while the stochastic RSI edged out of oversold territory, hinting at a possible bounce if auction pressures ease.

Regional markets mirrored these strains. Brazilian and Mexican indexes fell under the weight of broader emerging-market selling, and flat oil prices offered little help to commodity-linked currencies.
Currency Jitters Drive Outflows From Argentina ETF
ETF flows into the Global X MSCI Argentina ETF continued their slow drip of outflows as investors shifted focus to currency risk rather than equity gains.
Top five Merval winners yesterday included Loma Negra (+3.27 percent), IRSA (+2.70 percent), Trans Gas Sur (+1.59 percent), YPF (+0.39 percent), and Cresud (+0.36 percent).
On the losing side, Metrogas fell 3.96 percent, Edenor dropped 3.78 percent, Comercial del Plata lost 2.17 percent, Trans Gas Norte slid 2.06 percent, and Telecom Argentina declined 2.02 percent.
Argentina’s financial authorities face a stark choice. Continued central-bank interventions will cap official currency losses but risk depleting reserves further.
Without fresh external funding or clear fiscal policy direction, parallel market premiums and equity volatility are likely to persist.
Markets now await clearer signals on farm-tax reform and external support to gauge whether this strain can ease or will intensify ahead of critical political deadlines.
