Argentine inflation did not begin with the 2001 collapse, Peronism, or Javier Milei's presidency. Its historical preconditions emerged as the new state struggled to consolidate taxation, banking and a national currency in an economy strongly exposed to agricultural export receipts and foreign capital. The crisis of 1890 exposed vulnerabilities in credit and exchange-rate commitments. Chronic inflation, however, became a persistent feature principally after the Second World War; the break of 1975 pushed inflation into a different regime; 1989–90 brought hyperinflation; convertibility suppressed inflation during 1991–2001 but could not remove fiscal and external fragilities; and subsequent decades saw renewed interactions among foreign-exchange scarcity, deficits, debt and collapsing confidence in the peso. [1][2][3][4]

This long history has no satisfactory single-cause explanation. Public financing deficits, shifting external borrowing conditions, currency depreciation, imported intermediate goods, wage-price indexation, bank and central-bank liabilities, monetary substitution into dollars and political distributional conflict have all mattered, in varying combinations. Some episodes were dominated by monetary financing; others by currency and sovereign-debt crises despite attempts to restrict money growth. Understanding why a stabilization succeeded temporarily but later broke down requires separating its immediate nominal effects from the fiscal, banking, external and social arrangements needed to sustain it. [3][4][5]

1. Independence, customs revenue and monetary fragmentation

Nineteenth-century Argentina had to construct a functioning territorial state, a common tax base and a national market simultaneously. Buenos Aires commanded crucial customs revenues, while provincial governments depended on different fiscal structures and financing arrangements. Foreign coins, bank-issued liabilities and local instruments circulated alongside one another. There was no single, reliably accepted unit in which all long-term financial obligations could be denominated.

The cattle economy and the subsequent expansion of grain cultivation in the Pampas brought export earnings and helped finance railways, ports and imported machinery. That productive advantage did not confer financial autonomy. International credit, terms of trade and capital movements strongly influenced domestic solvency. The initial instability was not continuous high inflation from independence onward. It was an underdeveloped institutional capacity to absorb shocks to external financing and the fiscal position without repeated crises of banking and monetary credibility. [1][2]

2. Monetary unification and the Baring crisis, 1881–1891

The monetary reform of 1881 established a national currency linked to gold and sought to make monetary commitments intelligible to domestic savers and international investors. Convertibility was short-lived, and fragile banking arrangements persisted. Investment and public commitments increasingly depended on continued foreign capital inflows. When confidence reversed in 1890–91, banking stress, capital outflows, debt concerns and pressure on currency convertibility arrived together. The Baring crisis in London demonstrated the international importance of Argentine financial exposures. [1][2]

This was not yet the late-twentieth-century inflation regime. It was a failure to make liabilities payable in a stable medium during an external financing reversal. The Caja de Conversión and Banco de la Nación became important institutional responses. A lasting problem was visible: a country may expand production and infrastructure rapidly yet remain exposed to financial crises if its debts, exchange commitments and external financing needs are poorly matched.

3. Export prosperity and the limits of gold, 1900–1930

Early twentieth-century Argentina achieved high income per head, large-scale immigration, rapid urbanization and exceptional agro-export integration. Gold-based monetary rules gave domestic and foreign creditors an apparent guarantee of stability. They also made credit conditions dependent on the balance of payments. When gold and capital flowed in, lending and demand could expand. When external financing reversed, domestic credit and employment absorbed the contraction.

The gold arrangement was suspended during the First World War, partly restored and abandoned in December 1929. The Great Depression weakened export prices, damaged fiscal revenues and hurt domestic banks and workers. Greater nominal stability than in the later hyperinflation decades therefore coexisted with substantial vulnerability to output, employment and financial shocks. An economy need not be inflationary to be structurally fragile. [1][2]

4. The 1930s and the foundation of the central bank

The international collapse of agriculture and credit strengthened exchange controls and import-substituting industrial activity. In 1935 the Banco Central de la República Argentina was created as an initially mixed public-private institution responsible for currency issuance, reserves, banking oversight and countercyclical operations. Raúl Prebisch played an important role in its early operation. The new institution addressed the monetary fragmentation of the nineteenth century and the inability of automatic gold-standard adjustment to absorb severe external shocks. [1][6]

A lender of last resort can prevent a bank panic from becoming a generalized collapse in payments. But central-bank discretion also creates recurrent questions: when should credit be expanded, when should the Treasury be financed, how should exchange-rate pressure be handled, and who bears the cost of defending the currency? The BCRA did not automatically generate the inflation of later decades. Policy incentives, fiscal capacity and institutional rules shaped its use by successive governments.

5. Peronism, industrialization and distributional pressure, 1946–1955

War-era shortages of imports had encouraged domestic manufacturing. The first Peronist administration expanded collective bargaining, social protection and state intervention while using administered prices, foreign-exchange arrangements and trade policies to redirect resources. Manufacturing increased urban employment, but it also needed imported equipment, fuel and components. Much of the foreign-exchange supply continued to depend on agriculture. [3][7]

The resulting conflict was not merely one of state spending versus markets. Wage growth sustained demand and political legitimacy; industrial firms needed capital and intermediate goods; producers of export commodities reacted to exchange-rate and pricing policies; and the public sector sought to finance investment and social commitments. An overvalued currency could stimulate imports while weakening export incentives. A depreciation restored some export competitiveness but increased domestic costs and prompted wage renegotiation. Inflation reflected the interaction of financing, productivity, external scarcity and bargaining. Redistribution is not inherently inflationary; its effects depend on fiscal financing, supply capacity and the external constraint.

6. Stop-go growth and chronic inflation, 1955–1974

Governments after 1955 repeatedly combined stabilization plans, selective industrial support, capital controls, exchange-rate changes and wage policies. Economists described a stop-go economy: a period of rising output and consumption raised import demand; once foreign exchange became scarce, authorities depreciated the currency, restricted imports or contracted demand. Depreciation then raised the peso prices of tradable food and imported inputs, and workers and businesses sought to restore previous real incomes. The external correction was progressively eroded by domestic price adjustments. [3][4]

Daniel Heymann and Adrián Ramos find that annual CPI inflation between 1945 and 1974 was below 10% in only three years, but—with the exception of 1959—remained below 100%. Stabilization efforts in the late 1950s and in 1967–70 sometimes reduced inflation considerably. The absence of durable fiscal, external and distributional agreements meant that renewed growth could once again encounter the same foreign-exchange and wage-price constraints. [3][4]

7. The Rodrigazo of 1975 and the shift to high inflation

In June 1975, under President Isabel Perón, Economy Minister Celestino Rodrigo introduced major adjustments to the exchange rate and regulated prices amid fiscal imbalances, wage demands, political conflict and difficult external conditions. The Rodrigazo did not create every later problem, but it marked the shift from chronic inflation measured largely in tens of percentage points to a far more volatile process that would repeatedly reach triple digits. [3][4]

A devaluation immediately alters relative prices: importers must spend more pesos for the same dollars, exporters obtain more local currency per unit sold, and internationally tradable products can become costlier at home. These effects do not automatically imply permanently accelerating inflation. Persistence develops when wage contracts, commercial pricing, financing needs and expectations repeatedly react to the initial shock without a credible nominal anchor. The Rodrigazo disrupted confidence in price-setting agreements and increased incentives for shorter contracts and indexation.

8. The military dictatorship, financial liberalization and external debt

The dictatorship that began in March 1976 reshaped financial regulation and the relationship between banks, firms and foreign financing. Reforms in 1977 increased the role of private intermediation, interest rates and capital flows. The pre-announced exchange-rate adjustment schedule, known as the tablita, was designed to anchor price expectations. When domestic inflation exceeded scheduled depreciation, the real exchange rate appreciated, making imports relatively attractive and exports less competitive. financing positions became more dependent on continuous refinancing. [7][8]

Banking strains and foreign-currency borrowing amplified the vulnerability. If firms, banks or the public sector owed dollars while earning pesos, a sharp depreciation could undermine solvency even without an immediate increase in real indebtedness. The Latin American debt crisis of 1982 intensified these strains. Foreign borrowing was therefore not a neutral alternative to money creation. It could temporarily relieve financing pressure while increasing the cost of the next exchange-rate correction.

9. Democracy, the Austral Plan and unstable contracts, 1983–1988

Raúl Alfonsín's democratic government inherited foreign debt, accelerating inflation, weak investment and major demands for institutional reconstruction after military rule. The 1985 Austral Plan introduced a new currency and combined fiscal and monetary restrictions with price and wage coordination. It initially reduced inflation and gave contracts a new reference point. The durability of the achievement was undermined by recurring fiscal strain, changing administered prices and difficulties aligning wages, the exchange rate and credit conditions. [3][9]

Past inflation was increasingly embedded in current pricing. Frequent indexation and compressed contract horizons meant that each new inflation reading quickly influenced wages and prices. But inertia did not remove the need to finance the state. A price freeze without a sustainable budget eventually broke down. Restricting money while central-bank liabilities and public debt continued to compound also transferred rather than eliminated the financing problem. Understanding the difference between inertia and the flow of new fiscal and monetary pressure is essential to explaining the failure of successive plans.

10. Hyperinflation in 1989–90: collapsing demand for pesos

In 1989, households and businesses increasingly refused to hold pesos for more than very short periods. Wages were rapidly spent or converted into dollars and goods; suppliers shortened their quotation intervals; taxes lost purchasing power between accrual and collection. The BCRA's own 1989 annual report identified chronic inflationary financing of public deficits and the dynamics of remunerated banking and monetary liabilities as central contributors. Interest obligations could expand future money creation and debt needs precisely when inflation was rising. [5][9][10]

Hyperinflation is not simply ordinary inflation multiplied. Currency demand collapses, money circulates more rapidly and attempts to finance spending through issuance yield diminishing real resources. Paul Beckerman's historical study emphasizes the distress of government and central-bank balance sheets, short-term borrowing and high interest rates preceding the breakdown. The crisis accelerated the transition of presidential authority from Alfonsín to Carlos Menem and caused severe real-income and social losses. [5][9][10]

Transmission chain
  1. Fiscal gaps and interest on public liabilities
  2. repeated refinancing needs
  3. money issuance or short-term borrowing
  1. Falling trust in pesos
  2. rapid conversion into goods and dollars
  3. weaker money demand
  4. faster price adjustment
  1. Depreciation and inflation
  2. erosion of real tax collections
  3. additional pressure on public financing

These channels reinforced one another but were not identical. Lower primary spending alone could not immediately resolve all central-bank financing burdens; money restrictions without a debt solution could produce a refinancing crisis.

11. Convertibility in 1991: actual disinflation and a rigid anchor

The April 1991 Convertibility Law tied the austral to the dollar at 10,000 australes per dollar. With the introduction of the new peso in 1992, the practical parity became one peso for one dollar. The system constrained discretionary issuance and linked monetary liabilities closely to reserves. Exchange-rate stability became a visible rule for contracts, wages and prices. Inflation fell markedly: the IMF Independent Evaluation Office recorded December-to-December inflation of 84% in 1991, 17.6% in 1992, 7.4% in 1993 and 3.9% in 1994. [11][12]

This was genuine disinflation accompanied for part of the decade by economic and credit expansion. But an exchange-rate rule that stabilizes prices removes the ability to adjust the nominal exchange rate when external conditions change. Domestic prices, wages, employment, production and government financing must absorb shocks instead. As debts, deposits and pricing contracts were organized around dollar parity, abandoning it became progressively more disruptive. Price stability in the early years and long-run regime solvency were separate questions. [11][12]

12. The road to 2001: low inflation did not imply solvency

The Mexican financial crisis, turbulence in emerging markets, the strengthening of the dollar and Brazil's 1999 devaluation created an increasingly difficult external environment. A peso fixed to the dollar was relatively expensive against important trading partners. Recession from 1998 weakened tax receipts and increased the debt burden relative to output. Creditors demanded higher yields and refinancing became harder. Public debt sustainability, bank deposits and confidence in the parity were tied together. [11][12][13]

The 2001 corralito restricted deposit withdrawals, Argentina defaulted on part of its sovereign debt, and the parity ended in 2002. The peso subsequently weakened to approximately 3.90 per dollar by mid-2002 according to the IMF. The crisis destroyed employment, financial wealth and confidence. The IMF's independent evaluation identified failures in crisis management, notably the lack of a workable exit strategy when the existing currency arrangement had become increasingly difficult to maintain. A country can experience deep economic collapse without contemporaneous high inflation if the problem is debt and exchange-rate rigidity. [11][13]

13. After 2002: depreciation, redistribution and recovery

Leaving convertibility generated inflation through depreciation and relative-price adjustment while restoring some competitiveness for domestic production and exports. The effects were highly unequal. Dollar debtors and creditors, businesses with imported inputs, exporters, employees and savers were exposed differently to the restructuring and conversion of contracts. The nominal exchange rate is also a distributional price: its movement changes who receives foreign-exchange income and who pays higher domestic costs. [11][13]

Recovery drew on unused productive capacity, a newly competitive exchange rate, stronger commodity prices and a rebound in employment and revenue. Rapid growth after collapse did not prove that the chronic inflation problem had disappeared. It showed how a severely depressed economy can recover when demand, exports and productive utilization rise together. Durable stabilization still required credible public financing, price-setting institutions and confidence in domestic savings.

14. The 2007–2015 period and statistical credibility

Domestic-demand expansion, subsidies and public commitments interacted with growing restrictions on foreign exchange and the availability of external financing. Multiple exchange rates and controls increasingly affected importers, exporters, investors and households differently. Administrative restrictions could delay certain demands for dollars without making underlying foreign-exchange scarcity disappear. Informal markets therefore carried information that the official parity alone could not supply.

A further cost was the deterioration of official statistics. The OECD documents serious weaknesses in Argentine statistical production during 2007–15. The IMF issued a formal declaration of censure in 2013 over the reliability of CPI and GDP data; it was removed in 2016 after methodological and institutional changes. Inflation series spanning this period should not be joined mechanically with later nationally representative CPI observations without acknowledging scope and quality limitations. A loss of trust in statistics undermines wage bargaining, indexed contracts and the credibility of disinflation promises. [14][15]

15. Macri, external borrowing and the 2018 reversal

Mauricio Macri's government sought to normalize relations with international creditors, liberalize trade and exchange arrangements and adopt an inflation-targeting framework. Gradual fiscal adjustment relied substantially on continued market access. Portfolio capital inflows offered temporary financing but also created exposure to sudden reversal. A serious drought and a deterioration in international financial conditions helped precipitate the 2018 peso crisis. High interest rates could not durably stabilize the currency once investors doubted the refinancing capacity of the state and the sustainability of the debt path. [16][17]

The 2018 IMF stand-by arrangement ultimately authorized approximately US$57 billion, of which roughly US$45 billion was disbursed. Authorization and actual disbursement must not be confused. The Fund's own ex-post evaluation concluded that the program did not achieve its main objectives; only four of twelve scheduled reviews were completed. The crisis demonstrated how currency and sovereign-debt stress can reignite inflation even during policies explicitly intended to restrict money growth. [16][17]

16. Pandemic, drought and the final acceleration of 2020–2023

The pandemic sharply reduced activity and expanded demand for emergency government support in an economy already facing limited external borrowing opportunities. Monetary financing, central-bank liabilities and the later recovery of private demand complicated stabilization. International energy and food shocks also mattered, but countries exposed to similar global prices did not reproduce Argentina's inflation rates: domestic financing, monetary credibility and foreign-exchange arrangements remained decisive.

The 2022–23 drought cut agricultural foreign-exchange receipts. Foreign-exchange restrictions, delayed increases in regulated tariffs and pressure on parallel exchange rates intensified the dislocation of relative prices. By December 2023 monthly CPI inflation reached 25.5% and the calendar-year increase was 211.4%. Neither figure can identify a single cause: financing, expectations, reserve scarcity, exchange-rate changes and regulated-price adjustments interacted. [18][19]

17. Stabilization beginning in late 2023

After Javier Milei became president in December 2023, the macroeconomic program made fiscal balance and restrictions on monetary financing central objectives. An initial major currency depreciation and the correction of regulated prices raised many peso costs immediately. Spending restraint, tight monetary conditions and exchange-rate changes sought to slow the subsequent rate of price increases. The initial disinflation was accompanied by contraction in activity and real-income stress for parts of the population in 2024. [19][20]

A falling rate of inflation should not be confused with falling absolute prices. Stabilization means prices rise more slowly, not necessarily that previously accumulated increases reverse. Its durability depends on continued financing discipline, usable foreign-exchange reserves, the demand for peso assets, banking balance-sheet management and political acceptance of adjustment. Supporters of a strong fiscal anchor emphasize ending fiscal dominance; critics examine distributional effects, real exchange-rate appreciation and restricted credit. These are separate empirical questions rather than reasons to collapse a broad policy experience into a political verdict. [19][20]

18. Observations through September 2026

Official calendar-year CPI inflation declined from 211.4% in December 2023 to 117.8% in December 2024 and 31.5% in December 2025. These figures describe observed year-end results, not forecasts. INDEC reported 1.9% monthly inflation for September 2026 on 13 October. Monthly and annual rates are not directly comparable, and the September observation does not establish the outcome for all of 2026. [18][19][20][21]

In May 2026 the IMF projected year-end inflation of around 25%, conditional on fiscal and monetary discipline. That was a forecast, not an observed figure. The Fund also noted that disinflation had slowed during the first quarter, including a 3.4% monthly rise in March, and that reserve accumulation remained important. The private forecasters surveyed by the BCRA at the end of September expected 1.9% inflation for that month, subsequently matched by the official observation; their survey is not the central bank's own forecast. [20][21][22]

19. Poverty, wages and the difference between stabilization and welfare

Inflation is especially damaging to households whose earnings are paid at intervals while food, transport, utilities and rents change more frequently. Lower-income families generally have fewer opportunities to protect savings through foreign-currency or interest-bearing assets. Pensioners depend on indexation rules; small businesses face inventory replacement costs; wage earners can lose purchasing power between collective bargaining rounds. High inflation redistributes resources opaquely, but abrupt subsidy withdrawal and fiscal adjustment can also impose substantial immediate costs. [4][19]

INDEC's urban poverty measure reached 52.9% of persons in the first half of 2024, fell to 38.1% in the second half of 2024 and 28.2% in the second half of 2025, and stood at 32.3% in the first half of 2026. The observations concern 31 urban agglomerations, and comparisons across different halves of the year require caution about seasonality and measurement. The pattern is not proof that any single policy caused the entire change. It does show why real wages, employment and household purchasing power cannot be replaced by the inflation rate or fiscal balance as indicators of welfare. [23][24]

20. Fiscal finance, money creation and the central-bank balance sheet

The monetary explanation identifies a binding accounting constraint. If public spending and interest cannot be financed by taxes or sustainable voluntary lending, monetary issuance can become a source of financing. In an economy where demand for pesos is weak, this source quickly loses purchasing power. But it does not follow that every price responds immediately or mechanically to the stock of base money. Velocity, bank liabilities, real activity, private credit, expected depreciation and confidence determine how a monetary shock is transmitted. [5][10][16]

A proper fiscal explanation also distinguishes the primary deficit, interest expenditure, Treasury issuance, sterilization costs and central-bank liabilities. Lowering the primary deficit may not immediately resolve high debt service, foreign-currency exposure or looming refinancing needs. Conversely, monetary expansion during a recovery in real money demand is not mechanically equivalent to issuance during a run away from the currency. Durable stabilization requires consistency across budgets, debt maturities, exchange rates, bank balance sheets and the willingness of households and firms to save in pesos. [5][10][20]

21. The foreign-exchange constraint

Argentina needs foreign currency to import machinery, intermediate goods, some energy and pharmaceuticals; service foreign debt; and settle international investment transactions. Its foreign-exchange earnings remain heavily exposed to agricultural harvests and commodity prices, even as energy, mining and services have become more important. When the supply of dollars falls, peso depreciation can raise imported-input costs and domestic tradable-goods prices, while increasing the local-currency burden of foreign debt.

Exchange controls may preserve reserves temporarily, but different access prices can create parallel markets and incentives to alter export settlement and import timing. Abrupt liberalization without credible reserves and fiscal arrangements can also trigger capital flight. There is no contradiction between fiscal balance and the need for coherent exchange-rate institutions. A balanced central-government cash flow reduces one source of monetary pressure, but does not automatically provide dollars for debt maturities and external shocks. The IMF's 2026 program assessment continued to emphasize reserve accumulation. [16][20]

Transmission chain
  1. Falling export earnings or capital outflows
  2. dollar scarcity
  3. peso depreciation
  4. higher imported input and tradable-goods prices
  1. Wage and contract adjustment + expectations of further depreciation
  2. repeated repricing
  3. additional demand for dollars
  1. Credible fiscal balance + sustained demand for pesos + predictable access to foreign exchange
  2. reduced monetary-financing pressure and more durable disinflation

The regional mechanism links export revenue generation to domestic currency demand and import-intensive activity. The geographic categories below describe transmission channels, not measured provincial contributions, a precise origin-destination freight network or a claim that every location has the same economic exposure. The historical export and foreign-credit dependence and the contemporary reserve problem are documented in the cited monetary histories and IMF reviews. [1][2][16][20]

22. Informal dollarization and the legacy of hyperinflation

For many Argentines the dollar has become more than a foreign currency: it serves as a preferred benchmark for long-term savings, property transactions and household wealth. Repeated monetary reforms, depreciation, deposit restrictions, inflation and failed exchange-rate promises reinforced this behavior. Currency preferences established over decades do not immediately disappear when monthly inflation falls. [3][11][13]

This creates a macroeconomic paradox. Dollar savings protect private wealth from peso depreciation, yet widespread avoidance of peso assets reduces local money demand and weakens the central bank's ability to smooth disturbances. Foreign-currency banking deposits also require careful matching of bank assets and liabilities. Proposals for formal dollarization must answer operational questions about conversion rates, available dollars, central-bank liabilities, emergency liquidity and the adjustment mechanism following external shocks. Replacing a unit of account is not itself a solution for fiscal solvency.

23. Federalism, subsidies and the political economy of adjustment

Argentina's federal structure complicates stabilization. Provinces have fiscal commitments and depend in varying degrees on transfers, shared taxes and local revenue. Electricity, transport and other regulated prices differ in social and regional impact. Removing a subsidy can improve the budget while immediately increasing measured inflation and household expenses. The long-run effect depends on how the subsidy had been financed, on the timing of new price adjustments and on responses from wage bargaining and monetary policy.

Stabilization therefore involves competing claims on national income. Organized workers seek real wage protection; exporters prefer a competitive exchange rate; urban consumers resist food-price rises; manufacturers need access to imported components; bondholders demand credible repayment; and provincial governments must maintain services. A durable settlement requires fiscal and bargaining institutions that process these conflicts across administrations rather than relying exclusively on a single announcement of austerity or monetary discipline.

24. Competing theories and their period-specific explanatory power

Monetarist approaches emphasize issuance and nominal anchors. Fiscal theories focus on long-run public solvency, including central-bank liabilities. Latin American structuralist approaches highlight foreign-exchange constraints in economies with concentrated export revenues and import-intensive industrial growth. Inertial inflation theories examine backward-looking indexation and contract setting. Political-economy explanations place distributional conflict and the inability to commit to durable rules at the center of the problem. [3][4][5][10]

Argentine evidence requires distinguishing these theories rather than assuming each is equally important in every period. The 1989 collapse hinged on monetary financing, financial distress and currency demand. In 1991 exchange-rate anchoring broke expectations; in 2001 a rigid currency and unsustainable debt produced collapse despite price stability; in 2018 external borrowing and capital reversals were central; in 2023 fiscal finance, drought, reserve shortages and exchange adjustment interacted; and in 2024–26 lower inflation coexisted with continuing questions about reserves, growth and household income. The dominant mechanism shifts with balance sheets, institutions and external circumstances.

25. The 2026 test and the requirements for durable monetary stability

Observed disinflation in 2024–25 demonstrates the capacity to reduce price growth under a stronger fiscal restriction. It does not yet establish that the longer historical process has ended. Durable stabilization would require financing public commitments without recurrent monetization, increasing usable reserves, reducing foreign-currency debt vulnerabilities, restoring productive investment and credit, and allowing exchange-rate adjustments without systemic panic. No single condition automatically supplies the others.

The IMF's May 2026 assessment acknowledged progress in inflation and fiscal accounts while emphasizing reserve rebuilding, political risks and social protection. The BCRA survey released in October showed private expectations of only 1.5% GDP growth in 2026, below the IMF's 3.5% projection published in May; differing dates and assumptions make these conditional forecasts rather than rival measurements of a known outcome. Productivity, employment, crop outcomes, international prices, provincial finance and the credibility of peso contracts will all affect the eventual inflation path. [20][22]

Argentina's history is neither a mechanically repeated failure nor a linear rise in prices attributable to one government. It is a series of fiscal, exchange-rate, financial and distributional choices under different external conditions. The country has repeatedly demonstrated the ability to generate wealth, stop severe inflation for extended periods and recover production after crisis. The unresolved question is whether current disinflation can be converted into lasting demand for its currency, stable fiscal institutions and growth with sufficient foreign-exchange capacity to avoid another cycle of debt, dollar flight and depreciation.
