On the Eve of Peso Collapse: Argentinians Use Cryptocurrency to Preserve Their Last Value

As the midterm elections approach, Argentine President Javier Milei is tightening foreign exchange controls to support the peso exchange rate, while Argentine citizens like Ruben López are turning to cryptocurrencies to protect their savings.

A new strategy has emerged: using stablecoins pegged 1:1 to the US dollar to leverage the difference between Argentina’s official exchange rate and the parallel market rate. Currently, the peso’s value under the official rate is about 7% higher than in the parallel market. Cryptocurrency brokers explain the process as follows: first, buy US dollars and immediately exchange them for stablecoins; then, convert the stablecoins into pesos at the cheaper parallel market rate. This arbitrage operation, known as “rulo,” can quickly earn up to 4% profit per transaction.

“I do this trade every day,” said López, a stockbroker in Buenos Aires, who uses cryptocurrencies to hedge against inflation.

This cryptocurrency operation reflects a shift in how Argentines are coping with a new wave of economic turmoil. Ahead of the October 26 election, Argentina is depleting its US dollar reserves to boost the peso and prevent the exchange rate from breaking out of its trading band. Even with substantial US support, investors still expect the peso to depreciate further after the election.

Recently, the Central Bank of Argentina issued new regulations prohibiting citizens from reselling US dollars within 90 days to curb rapid arbitrage trading, and the “rulo” arbitrage model emerged almost immediately. On October 9, trading platform Ripio reported, “The trading volume of stablecoins against the peso surged 40% in a single week,” attributing this to “users profiting from exchange rate fluctuations and market opportunities.”

For some Argentines, such operations are a necessity. After all, the country has defaulted on its debt three times this century. When Milei was elected in 2023, he promised to end these financial woes. He has indeed achieved some results, such as reducing the annual inflation rate from nearly 300% to about 30%; but the peso has still depreciated sharply, partly due to Milei’s currency devaluation policy upon taking office and partly due to increased investor concerns about the upcoming election.

The “rulo” arbitrage phenomenon indicates that the role of cryptocurrency in Argentina has fundamentally changed: from a novelty that once piqued the curiosity of citizens—including Milei himself—to a financial tool for protecting savings. In the United States, cryptocurrencies are often used as speculative instruments; but in Latin America, they have become a choice for seeking stability. In countries like Argentina, Venezuela, and Bolivia, crypto technology helps people circumvent the triple pressures of “currency volatility, high inflation, and strict foreign exchange controls.”

“We provide users with channels to buy cryptocurrencies with pesos or dollars and then sell for profit—that’s our daily business,” said Manuel Beaudroit, CEO of local crypto exchange Belo. “Obviously, the exchange rate difference can bring considerable profits.” He mentioned that in recent weeks, traders could earn 3%-4% per transaction, but also cautioned that “this level of return is very rare.”

Other trading platforms have seen similar situations. Another local platform, Lemon Cash, reported that on October 1, the day the Central Bank of Argentina’s 90-day dollar resale ban took effect, its total crypto trading volume (including buying, selling, and exchanging) surged 50% above average levels.

“Stablecoins are undoubtedly a tool for obtaining cheaper US dollars,” said Julián Colombo, head of Argentina at another trading platform, Bitso. “Cryptocurrencies are still in a regulatory gray area; the government has not yet clarified how to regulate stablecoins or restrict their liquidity, which has created the conditions for the rise of ‘rulo’ arbitrage.”

However, the growth in stablecoin trading is not solely due to arbitrage. As the Milei administration faces a critical election and the economy comes under renewed pressure, many Argentines are also using cryptocurrencies as a hedge against the potential further devaluation of the peso.

“Inflation and political uncertainty have made us more conservative, so I don’t have any peso savings or investments—I only use pesos for daily expenses,” said Nicole Connor, head of the Argentine ‘Women in Crypto Alliance.’ “All my savings are in cryptocurrencies and stablecoins, and I try to earn returns through them.”

Nevertheless, cryptocurrency operations are not without risk. In Argentina, stock market trading is tax-free, but profits from cryptocurrency trading are subject to a tax of up to 15%; in addition, frequent trading may attract the attention of banks, which often require proof of funds for users making repeated large transfers.

But analysts believe that as economic difficulties persist, Argentina’s reliance on stablecoins may deepen; across Latin America, more and more people are using such tools to protect their assets against fiscal turmoil and election shocks.

“Stablecoins will always exist,” said stockbroker López. “The US dollar occupies an important position in Argentine society and daily life because it is our safe haven against local currency risk.”
