Argentina's Senate voted 46 to 22 on Thursday, September 24, 2026, to fundamentally reshape the central bank's mission. The reform strips the Banco Central de la República Argentina of nearly all its powers except one: protecting the peso's value. It's a stark reversal of decades of monetary policy that allowed governments to raid the central bank's coffers at will.
The bill eliminates the central bank's ability to lend to the national government, provinces, and municipalities. Gone are the two mechanisms past administrations exploited: adelantos transitorios (short-term cash advances) and letras intransferibles (non-tradable IOUs). The central bank can no longer purchase government bonds at issuance, though it may trade them on open markets at actual prices. These weren't minor accounting adjustments—they were the financial plumbing through which successive governments, including President Javier Milei's own administration, had siphoned money from the bank to cover budget shortfalls.
The Institutional Overhaul
The reform rewrites the central bank's charter, scrapping its previous mandate to pursue financial stability, jobs, and economic development with social equity. That broader agenda is now history. The bank's single, laser-focused goal is currency preservation. Milei presented the measure in a national television address on July 30, framing it as essential to ending inflation. "The end of inflation begins," he declared on social media, celebrating what amounts to a constitutional constraint on monetary adventurism.
The Senate modified one critical provision before passage. The Chamber of Deputies had passed the bill on August 26 by 144 votes to 102, with 9 abstentions, requiring a two-thirds supermajority in both chambers to remove bank officials. Senators changed that standard. Now the president can appoint and remove bank leadership with approval from just 37 of 72 Senate votes—an absolute majority. Bank officials will serve six-year terms renewable once. Senator Agustín Monteverde of Milei's La Libertad Avanza party said the blocs had agreed to these revised leadership rules. The measure passed the Senate's revised article 66 to 2, with Peronist support.
The law also seals the central bank's international reserves from creditor seizure while requiring yearly profits to settle old Treasury debts still unpaid to the bank. Profits from a weaker peso or higher gold prices—previously sent to the Treasury as dividends—must now remain in the bank's capital. The president loses his unilateral power to remove bank officials, and the Economy Ministry loses its board seat.
The IMF Reckoning
On the same day, Argentina made its first principal repayment under its IMF program, transferring approximately US$793 million on Friday, September 25. The payment equaled 583.3 million special drawing rights (SDRs), calculated at the IMF's rate of US$1.36008 per SDR on that date. At the central bank's official exchange rate of 1,518.74 pesos per dollar on September 24, the sum reached 1.2 trillion pesos.
This repayment represents one-twelfth of the SDR 7 billion (roughly US$9.5 billion at current rates) that Argentina drew in March 2022 under its Extended Fund Facility. The IMF structures such loans as twelve half-yearly slices, with principal repayment beginning four and a half years after each drawing. Argentina paid SDR 1.71 billion in interest and fees from January through August 2026, but this marks the first principal slice.
Argentina remains the IMF's largest debtor, owing approximately SDR 42.6 billion—roughly US$58 billion—as of August 2026. The debt spans multiple administrations. President Mauricio Macri's government took the largest IMF loan in history in 2018, approved at SDR 40.7 billion. Before that program ended in 2020, Argentina had drawn SDR 31.9 billion. President Alberto Fernández's administration refinanced that debt in 2022 with a new extended loan of SDR 31.9 billion. Milei's government negotiated a third arrangement in April 2025 for SDR 15.3 billion, marketed as US$20 billion, of which approximately SDR 11.5 billion has been disbursed.
Reserves Under Pressure
The Treasury funded the IMF repayment by drawing on its dollar deposits at the central bank—US$2.23 billion as of September 22. The Treasury uses those dollars to purchase SDRs, then transfers them to the Fund. This mechanism lowers gross reserves by roughly the payment amount while leaving net reserves unchanged, according to analysts. Gross reserves closed at US$48.845 billion on Thursday, September 24, their lowest level that month. They'd fallen US$481 million on Wednesday, partly due to a US$100 million payment to CAF, a Latin American development bank.
An IMF staff team arrived on Monday, September 21, for the third review of the 2025 program, led by Joyce Wong on her first review as mission chief for Argentina. The team is verifying budget and reserve targets with the economy ministry and central bank. Economy Minister Luis Caputo was in New York with Milei for the United Nations General Assembly. If staff agree and the Executive Board approves, Argentina can draw SDR 636 million, roughly US$865 million, to refill Treasury deposits. No staff-level agreement had been announced by Friday.
Finance Secretary Federico Furiase declared on Monday that the targets were "super cumplidas"—more than met. The next IMF bill arrives in early November: SDR 636 million in interest and charges. A second principal slice of SDR 250 million, about US$340 million, is due December 24. On January 9, 2027, Argentina owes bondholders approximately US$4.3 billion on Globales and Bonares bonds from its 2020 restructuring. The IMF projects Argentina's total payments at roughly US$7.7 billion in 2027 and US$9.6 billion in 2028, at current SDR rates.
Why This Matters:
Argentina's central bank reform represents a hard-learned lesson about the fiscal costs of monetary discretion. By constitutionally binding the central bank to a single mandate—currency preservation—Milei's government is attempting to eliminate the institutional mechanism through which decades of politicians extracted resources to cover spending they couldn't justify to voters. The reform doesn't promise immediate price relief; it changes the rules for the long term. For Argentines earning, saving, or paying rent in pesos, it's a structural commitment that governments can no longer simply print their way out of fiscal crises. The simultaneous IMF repayment, while manageable, underscores Argentina's continued debt burden and the limited room for error. With US$58 billion owed to the Fund and billions more due to bondholders in coming months, the government's ability to maintain spending discipline—not just monetary discipline—will determine whether this reform succeeds or becomes another broken promise.
