Argentina’s Monetary Report Card: Promise versus Delivery under Milei

Javier Milei won by promising to abolish the central bank and scrap the peso. He kept neither, and now runs the most hands-on monetary regime in the hemisphere. Inflation still collapsed, from 25 percent a month to near 2. The revolution he sold did not do it. A budget surplus propped up by elections and borrowed dollars did, lashed to an exchange-rate band that floats on the very inflation it is meant to kill. The win is real. Nothing makes it last.

Monthly inflation ran at 25.5% in December 2023. Javier Milei had campaigned on three monetary commitments, each stated without qualification: dollarization of the economy, closure of the Banco Central de la República Argentina, and a deficit of zero. Days after the November 2023 runoff the office of the president-elect reaffirmed that the closure of the central bank “no es un asunto negociable.” The inaugural address carried the fiscal pledge in three words, “no hay plata.”

An economic argument sat beneath the rhetoric. Argentina had removed thirteen zeros from its currency across four reforms between 1969 and 1992, defaulted on sovereign debt nine times since independence, and entered 2023 with annual inflation above 200% and a central bank financing the Treasury directly. In that setting the promise amounted to credibility imported wholesale.

Neither institutional commitment survived. Four successive peso regimes arrived in their place, and monthly inflation printed 2.1% in May 2026.

Three questions order the grade that follows: whether confidence in the peso returned, what anchored it, and whether the arrangement now in force can keep holding it.

The scrub

Scrub the headline print

On 1 January 2026 the current regime entered force. Indexation is its defining feature: the band’s maximal monthly depreciation at month T equals headline CPI inflation at month T−2. Permitted depreciation widened from 2.5% in January 2026 to 3.4% in May while headline inflation fell from 2.9% to 2.1%. A band that widens during disinflation is the procyclical loosening indexation implies.

Headline inflation has printed at or above 2% in every month since September 2025, nine consecutive prints. Real transactional balances remain below where they stood at the start of the program. The core print of 1.9% in May is the first below that line. Disinflation that stalls at a 2% floor while the nominal anchor moves with lagged prices is a different object from disinflation that converges.

The verdict

The record reads in four states. Delivered: the disinflation from 25.5% to 2.1% per month, the parallel premium from triple digits to near parity, a fiscal surplus held every month since January 2024, and the legibility of the monetary aggregate restored. Reversed: dollarization and the closure of the central bank, replaced by an actively managed peso regime. Partial: the cepo, lifted for individuals in April 2025 and still binding on corporates. Held by discretion: the surplus, whose deficit rule remains a pending IMF benchmark, and the reserve position, negative on net and financed by borrowed buffers.

Falsifiable by design, this reading may already be meeting its falsifier. A corridor that held through a genuine political shock, with the budget loosening and the disinflation surviving, would weaken the claim that the anchor is borrowed. Core inflation breaking decisively below 2% under the band would weaken the inertia mechanism, and the May core print of 1.9% is the first below that line. Pre-registered for the December 2026 print, the persistence-break test is the scheduled adjudication of both. Until those prints exist, the verdict stands as the evidence leaves it. Disinflation is real, and the institution that would make it last is still the one promise the program has not kept.

Method

Data are frozen at the May 2026 consumer-price print, and every figure here is computed on that vintage. That freeze is itself a fact about the regime, since the band indexes to a CPI whose methodology is under political dispute, still carrying expenditure weights from the 2004–05 household survey, its scheduled rebasing shelved after the resignation of INDEC’s director in February 2026. A regime indexed to that number has to be read against a stated vintage of it.

Base money, reserves, and the official and parallel exchange rates come from the BCRA; consumer prices from INDEC; the reserve path, the maturity schedule, and Fund credit from IMF Country Report 2026/105, documentary rather than pipeline-estimated and flagged as such at the source line of each figure.
