The Argentine peso reached a new all-time low against the US dollar: the currency has lost an astonishing 99.8% of its value since 2009.

Next, we'll discuss what explains this decline, how it impacts Argentinians, and what's needed to reverse it.

Why did the Argentine peso register a new all-time low against the dollar?

A record low is the lowest level a currency reaches against another throughout its entire trading history. The Argentine peso hit that point against the dollar, marking one of the biggest currency collapses in modern economic history.

The monthly chart for the ARS/USD pair shows a near-vertical decline over the years. In 2010, 1 dollar was worth just over 3 pesos. Today, the official exchange rate is around 1,480 pesos per dollar, although the parallel market typically shows a wider gap.

This devaluation is not an isolated event. On the contrary, it results from recurring cycles of uncontrolled monetary expansion to finance fiscal deficits. Furthermore, capital controls and the loss of international reserves have exacerbated the currency's deterioration.

The administration of Javier Milei, which began in December 2023, implemented a strong orthodox adjustment. It cut public spending, eliminated subsidies, and carried out an initial devaluation . As a result, monthly inflation fell from hyperinflationary levels to more manageable figures.

However, the two-year chart reveals that depreciation continued, albeit at a more moderate pace. The currency remains under pressure from the gap between inflation and the exchange rate. Furthermore, the need to accumulate reserves continues to put pressure on the peso.

How does this downturn affect Argentina's economy?

The loss of value directly impacts citizens' wallets. For Argentinians, it means a constant erosion of the purchasing power of wages and savings in pesos. Furthermore, many families are seeing their incomes rapidly disappear.

This scenario is driving the informal dollarization of the economy. As a result, many prefer to hold physical dollars or cryptocurrencies like stablecoins as a hedge. Businesses, meanwhile, face enormous difficulties in planning long-term investments in such an uncertain environment.

Internationally, such a weak peso makes imports more expensive , complicating trade relations and impacting part of the external debt. Argentina, rich in soybeans, lithium, and gas, sees its ability to attract foreign investment limited by exchange rate risk.

Experts agree that a profound structural reform is needed. This includes permanent fiscal discipline, central bank independence, and trade liberalization. Only in this way, they argue, can the cycle of crises that has plagued the country for decades be broken.

Meanwhile, the peso's record low serves as a global reminder. Although the government averted an immediate collapse, the road to stability remains long. Recent history illustrates how a currency's fall impacts the daily lives of millions.
