Argentina's 99.8% Peso Collapse: Is Milei's "Bitter Medicine" Working, or Is the Market About to Call His Bluff?

A 2T Economics Deep Dive

I've been staring at the same chart for a week now, and I still don't like what it's telling me. Since 2009, the Argentine peso has lost 99.8% of its value against the dollar — the sharpest devaluation on record for the currency. If you'd swapped dollars for pesos back in 2010, three pesos would have bought you one greenback. Today, that same dollar buys you a number so large it barely fits the headline.

The evidence suggests this isn't just a chart problem. It's a governability problem. Javier Milei rode into the Casa Rosada with approval ratings north of 50%, promising to torch the old playbook of subsidies, deficit spending, and currency controls. Today, his approval is hovering closer to 40%, after bottoming out around 36% earlier this year. Health and education spending have been slashed, informal employment has hit record highs, and dozens of legacy manufacturers have shuttered plants.

So here's the question every investor with capital parked in Argentine bonds, ADRs, or peso-denominated assets actually needs answered: is this a temporary, necessary correction, or the early tremors of a structural crisis?

A boots-on-the-ground perspective reveals it's genuinely both — and pretending otherwise, in either direction, is how people lose money on this trade.

The Bear Case: What the Household Balance Sheet Actually Looks Like

Let's not sugarcoat this. The social cost of the Milei shock has been real, and it shows up in hard numbers, not just political rhetoric.

Healthcare and public services took the first hit. In his opening year, Milei's government cut health spending by roughly 48%. That's not a rounding error — that's a household in Buenos Aires losing access to a subsidized clinic overnight. As private insurance became unaffordable for a population with shrinking purchasing power, Argentines flooded back into an already-underfunded public hospital system. More demand, less funding — a combination that eventually forced the legislature to reverse course and vote through renewed health spending increases, a tacit admission that the initial cuts overshot.

Subsidy withdrawal hollowed out household budgets. Electricity, water, gas, and fuel subsidies were pulled aggressively, and a wave of public infrastructure projects — the kind of highway, port, and grid investment that normally pulls foreign capital into a developing economy — were simply frozen. That's not a neutral line-item cut. Public works function like a jobs program and an investment thesis rolled into one: contractors get paid, workers spend locally, tax revenue flows back to the state. Freeze that, and you freeze a multiplier effect the economy was leaning on.

The industrial base is bleeding. This is the part that should worry anyone thinking about Argentina as a manufacturing or nearshoring play. More than 200 traditional footwear manufacturers have closed in recent years. A major domestic producer that supplied private-label and licensed athletic footwear for global brands shut down a plant this year and shifted production abroad. Argentina's largest tire manufacturer has moved part of its production offshore as well. The pattern is consistent: decades of protectionist tariffs and subsidies had propped up margins for legacy Argentine industry. Strip those protections away in favor of trade liberalization, and companies that can't compete on cost simply relocate or die.

Informality is at a record high. Argentina's informal labor market now sits at 44.2% — the highest in the series' history — with roughly 6 million workers operating off the books. That's a fiscal death spiral in slow motion: informal workers don't pay income tax, the state's revenue base shrinks, the pension system comes under more strain, and public investment capacity shrinks further, which in turn pushes more displaced industrial workers into informal, lower-quality jobs. Headline unemployment sits around 7%, but that number is doing a lot of heavy lifting — the underlying labor quality has clearly deteriorated.

And then there's the corruption overhang. Milei built his entire brand on being the outsider who'd tear down the "political caste." That narrative has taken real damage from allegations involving people close to him — including reports of influence-peddling tied to his inner circle, and a crypto-token promotion scandal that raised questions about who benefited from the hype. For a libertarian outsider whose entire value proposition was I'm not one of them, these stories cut deeper than they would for a conventional politician.

The Bull Case: What the Bears Are Conveniently Leaving Out

Here's where I have to push back on the doom narrative, because a lot of the loudest commentary is either historically illiterate or arguing in bad faith.

Context matters — Milei didn't build this crisis, he inherited it. The "worst devaluation in history" framing measures from 2009, running through the Cristina Fernández de Kirchner, Alberto Fernández, and Mauricio Macri administrations. Blaming a president roughly two years into office for a currency collapse fifteen years in the making is, frankly, a lazy read. If anything, on the inflation side, Milei may be the administration doing the least damage of the last decade.

Inflation is actually cooperating. Annual inflation is running around 33%, but the more telling number is the trendline: last month's print came in at 1.9%, undershooting expectations of roughly 2%. The government's own year-end projection sits near 30% annualized. Compare that to 2023, the year before Milei took office, when Argentina posted 200% annual inflation. That is not a rounding error — that's a different macroeconomic universe. Whatever else you think of the shock therapy, the disinflation trajectory is real and it's fast.

The peso might actually be overvalued right now — which sounds like a strange thing to say about a currency that's lost 99.8% of its value, but stick with me. A stronger-than-expected peso is starting to squeeze two sectors that badly need a competitive exchange rate: agricultural and mineral exporters, and inbound tourism. Visitors who found Buenos Aires a bargain destination a few years ago are now finding it considerably more expensive in dollar terms. That's a genuine trade-off — currency stabilization helps domestic purchasing power but erodes export and tourism competitiveness. There's no free lunch here, and Milei's team knows it.

3% growth without a stimulus binge is not nothing. Anyone can juice GDP growth with expansionary spending — deficit-financed infrastructure booms have goosed headline growth numbers plenty of times in economic history, including in the United States during periods of heavy federal spending. The catch is always the same: unequal, debt-fueled growth that eventually requires painful deleveraging. Argentina posting 3% projected annual growth while running fiscal discipline and a primary surplus is a meaningfully different — and more durable — kind of number.

The credit markets are voting with their feet. Both Fitch Ratings and S&P Global Ratings have upgraded Argentina's sovereign credit rating this year. That matters more than any political poll, because it's the signal that determines whether pension funds, sovereign wealth funds, and institutional allocators are willing to put capital back into Argentine debt. Rating upgrades tend to be self-reinforcing: better ratings attract more foreign investment, more investment supports currency stability and lower inflation, lower inflation allows for lower interest rates, and lower rates unlock consumer and small-business credit — auto loans, mortgages, working capital — that actually circulates through the real economy.

Skin in the Game: My Actual Read

I'll say the quiet part out loud: I think Argentina needed a shock. Fifteen years of price controls, runaway subsidies, and fiscal irresponsibility under both Kirchnerist and, later, even the ostensibly market-friendly Macri administration were not producing a sustainable outcome. Something had to give.

But "necessary" doesn't mean "correctly calibrated." Where I think Milei has genuinely erred is treating health and education as line-item expenses rather than investments. You don't build a competitive, high-productivity economy by gutting university funding and public health infrastructure — you get strikes, brain drain, and a workforce that can't move up the value chain. Similarly, stripping every protection from strategically important industries risks a level of deindustrialization that will be extremely difficult to reverse once supply chains and skilled labor pools relocate elsewhere for good.

There's also a harder truth in the disinflation story that Milei's supporters tend to gloss over: it's not particularly difficult to bring inflation down when you've simultaneously gutted the purchasing power of the poorest households, cut subsidies on essentials, and pushed millions into informal, subsistence-level work. Reduced consumption from the bottom of the income distribution mechanically reduces demand-pull inflation. That's not a monetary policy triumph — that's disinflation achieved by excluding your most vulnerable citizens from the consumption economy. It's a legitimate critique, and investors underwriting the "Milei turnaround" thesis should price that fragility in.

Heading into next year's presidential election, the main opposition threat is Axel Kicillof — a former economy minister (2013–2015) and current governor of Buenos Aires Province, generally seen as a protégé of Cristina Kirchner but actively trying to rebrand himself as a more moderate, technocratic center-left alternative, distancing himself from the Fernández-era track record. Whether Argentine voters, even at 40% approval for the incumbent, are willing to hand the keys back to anything resembling the old Peronist playbook remains genuinely uncertain.

The Bottom Line for Investors

• Devaluation context: 99.8% peso depreciation since 2009 — but the bulk of that predates Milei; recent trend is disinflationary, not accelerating.

• Inflation trajectory: From ~200% annualized (2023) to a projected ~30% this year — one of the fastest disinflations in modern sovereign history.

• Growth: ~3% projected, achieved under fiscal discipline and a primary surplus, not stimulus.

• Credit signal: Both Fitch and S&P Global have upgraded Argentina's rating in the current cycle.

• Structural risk: Record informality (44.2%), a wave of manufacturing closures, and a real corruption overhang tied to Milei's inner circle.

• Political risk: Approval near 40%, a rebounding but far from dominant position heading into next year's election against a rebranded Peronist challenger.

This is not a clean story, and anyone selling you a one-line thesis — "Argentina is an economic miracle" or "Argentina is collapsing" — is selling you something simplified enough to be wrong. The disinflation and credit-rating trajectory are genuinely investable signals. The informality, industrial hollowing-out, and corruption exposure are genuinely investable risks. Position sizing, not conviction, is what should separate the investors who do well on this trade from the ones who get burned by it.

If you want to go deeper on how currency crises like this one typically resolve — and how often the "this time it's different" narrative turns out to be exactly wrong — I'd point you toward "This Time Is Different: Eight Centuries of Financial Folly" by Carmen Reinhart and Kenneth Rogoff. It's the single best historical framework I know of for separating genuine structural turnarounds from the early innings of the next default cycle, and it's essential reading before you size any position in Argentine risk.
