Background on Key Figures and Context

The Argentine peso has experienced a significant 5.49% depreciation against the US dollar this week, closing at 1,467.41 pesos per greenback following a period of market volatility after the ruling party’s defeat in Buenos Aires’ legislative elections.

This is the largest weekly depreciation of the peso since late 2023, when former ultraliberal president Javier Milei was in office. The defeat by 14 points of the ruling party, led by candidates from peronist governor Axel Kicillof in Buenos Aires—the country’s most populous province—triggered uncertainty about the government’s prospects in the national legislative elections on October 26. The government had hoped to gain seats in a Congress where it is currently in the minority to push through reforms.

Market Reactions and Government Interventions

The peso plummeted at the start of trading on Monday following the aforementioned defeat. The currency’s quote neared the upper limit of the floating band established by the government at 1,471 pesos per dollar.

In response to this week’s market turbulence, the Argentine government initiated interventions in the foreign exchange market using funds from the National Treasury to support the peso, as an agreement with the International Monetary Fund (IMF) signed in April restricts central bank intervention until the currency’s quote reaches the band’s ceiling.

Inflation and Market Sentiment

Despite the positive August inflation rate of -1.9%—matching July’s level—market anxiety persisted, as many analysts believe the peso is overvalued. This sentiment was further fueled by Argentine stocks trading on Wall Street losing up to 30% in certain shares and the Merval index, measuring leading Argentine equities, declining 11.90% over the week in the Buenos Aires stock exchange.

Political and Corruption Scandal Context

Market pressure intensified amid a corruption scandal involving President Milei’s sister, Karina Milei, who also serves as the Secretary General of the Presidency.

This month, for the first time, Congress overturned a presidential veto on increased funding for disability services. The following week, lawmakers will debate two more vetoes concerning financing for pediatric hospitals and universities.

IMF Support and Funds Received

This week, the government received further backing from the IMF through its spokesperson, Julie Kozack, who acknowledged “the significant progress made in reducing inflation.” Argentina has already received approximately 14,000 million dollars from the new IMF loan.
