Milei vowed to close Argentina’s central bank — But will he do it?

The challenge of replacing Argentina's peso with the United States dollar (and potentially Bitcoin) will be great, but it's not insurmountable.

The image of a presidential candidate destroying a model of the central bank with a sledgehammer will not leave Argentines' memories for a long time. But once President-elect Javier Milei is seated on the throne on Dec. 10, will he still have the courage to follow a winding and risky path?

Argentina carries — with its nine defaults — the title of world champion in the category of defaulting on risk. It is currently the International Monetary Fund's largest creditor, and with a credit risk assigned by Fitch Ratings as CCC — fourth from the bottom score — it needs to fundamentally change its economy.

I'm no fortune teller, but I can offer some insight into the process. Let’s start by recognizing that it is not impossible for a country to live without a central bank. Currently, there are 198 countries and 180 currencies. Ten percent of them do not use their own currency.

Another important reality is that the IMF does not have “monetary” in its name unintentionally. It likes central banks, and aArgentina’s main creditor, its opinion will be very important in the process.

We also have Argentina's monetary base. According to the county's latest balance sheet, that figure stands at $7.7 billion. (That's 220,000 Bitcoin, for those keeping track, and just slightly more than MicroStrategy's $6.9 billion valuation.) For comparison, the U.S. monetary base is greater than $5 trillion.

That figure suggests the challenge of replacing the monetary base will be great, but not insurmountable. One of the difficulties of exchanging currency is obtaining paper money for day-to-day activities, but we in the crypto world know that both stablecoins and Bitcoin can help a lot in this process.

It would make sense if Milei uses the blueprint established by El Salvador. That would mean first adopting the U.S. dollar, and to subsequently begin accepting Bitcoin.

A currency generally requires “legal tender” status, which means that all establishments in the country are required to accept it. Milei may institute a major policy change in this regard. If he is really a liberal (the classical term for “libertarian”), he may allow the market to decide which currencies succeed.

It is well known that Argentines keep a large amount of savings in dollars outside of their country. The numbers are uncertain, but it could be in the range of S100 billion to $300 billion. But what is really important is that, under the new exchange-rate rules of this new government, that money may feel comfortable returning to the country.
