No country’s financial system can be understood without its history, and Peru’s is dominated by a single searing event: the hyperinflation of the late 1980s, when prices rose so fast that the national currency effectively collapsed. That trauma — and the radical reforms that followed it — explains almost everything distinctive about Peruvian finance today: the fierce commitment to macroeconomic discipline, the independence of the central bank, the lingering dollarization, the openness to markets. But the story runs deeper, from the silver and guano booms that tied Peru’s fortunes to commodities and external markets, through a twentieth century of instability and failed experiments, to the catastrophe of the 1980s, the wrenching ‘Fujishock’ stabilization of the 1990s, and the long era of orthodoxy that made Peru an emerging-market success on macro even as its politics stayed turbulent. This module traces that road — how a country learned, the hard way, to value stability above almost everything, and what that hard-won stability did and did not deliver.
Peru’s financial history begins, like much of its economic history, with what could be dug out of the ground or scraped off its coast. Under Spanish colonial rule, Peru was one of the great silver economies of the world, its mines (above all the legendary Potosí, in territory then administered from Lima) feeding bullion into a global empire — an early lesson that Peru’s prosperity would rise and fall with the value of its commodities and the demands of distant markets. After independence in the nineteenth century, a new boom arrived in the unlikely form of guano, the nitrogen-rich seabird droppings that became a prized fertilizer; for a few decades, guano exports filled the national treasury and financed the state.
The guano era set a pattern that recurs through Peruvian history and that this track will trace into the present: a commodity windfall brings a surge of revenue, the boom is mismanaged or squandered or simply ends when prices fall or the resource is exhausted, and the country is left exposed — often having borrowed against the boom. Guano gave way to debt and, eventually, national crisis. The deep lesson encoded in this history is commodity dependence: an economy whose fortunes are tethered to the prices of things it extracts — once silver and guano, today copper and gold — is inherently cyclical and externally vulnerable. That vulnerability shapes Peruvian finance to this day, and it is the oldest theme in the country’s economic story.
The twentieth century brought Peru repeated swings between economic models, none of which delivered lasting stability. There were periods of liberal, export-led growth and periods of state-led development; there were oligarchic governments and, in the 1960s and 1970s, an ambitious military government that nationalized industries, expropriated large estates in a sweeping land reform, and expanded the role of the state across the economy. Each swing left its mark, but the broader picture was one of instability: an economy that could not escape its commodity dependence, a state whose finances were chronically strained, and a society marked by deep inequality between a modernizing coast and a poorer, often indigenous interior.
By the late 1970s and into the 1980s, these strains were compounding. The state had taken on heavy debts, the economy struggled, and successive governments reached for short-term fixes — printing money, controlling prices, borrowing more — that papered over problems while building toward a reckoning. Layered on top, from around 1980, was the eruption of a brutal internal conflict, as a violent insurgency and the state’s response plunged parts of the country into years of bloodshed and fear, deepening the sense of a state losing control. This is the troubled inheritance into which the catastrophe of the late 1980s arrived: an economy already fragile, a state already strained, and a society already under enormous stress. The hyperinflation did not come from nowhere; it was the culmination of decades of accumulated instability.
In the second half of the 1980s, Peru experienced one of the worst hyperinflations in modern history. A government pursuing heterodox policies — expanding spending, controlling prices, and ultimately financing deficits by printing money — lost control of inflation entirely, and prices began to rise not by percent per year but by enormous multiples, accelerating into a self-feeding spiral. When inflation reaches such extremes, money stops doing its job: it cannot store value for even a few days, prices must be re-marked constantly, people rush to spend cash the moment they receive it or flee into dollars and goods, and ordinary economic life becomes a frantic struggle against a melting currency.
The human and financial consequences were devastating. Savings held in the local currency were wiped out; real wages collapsed; the formal financial system, which cannot function without stable money, was hollowed out; and the trust that any monetary system depends on was shattered. It is hard to overstate how formative this episode was for the Peruvian relationship with money. A generation learned, viscerally, that their own currency could betray them utterly — which is why, as Module 1 noted, the dollar became a refuge and why dollarization proved so persistent. And it is why the overriding lesson Peru drew was that nothing matters more than monetary stability: not growth, not redistribution, not industrial policy, but first and above all, never again letting inflation destroy the currency. That conviction, forged in catastrophe, is the foundation of the modern Peruvian financial system.
The response to the catastrophe was as radical as the crisis. At the start of the 1990s, a new government imposed a drastic stabilization and a sweeping program of market reforms, a shock so abrupt it entered the language as the “Fujishock.” Prices were freed, subsidies slashed, the budget brought under control, and the money-printing that had fueled the hyperinflation halted — brutal medicine that caused real short-term hardship but did break the inflationary spiral. Alongside stabilization came structural reform along the lines then being urged across the developing world: opening the economy to trade and foreign investment, privatizing state-owned enterprises, and rolling back the heavy state interventionism of the previous decades.
This was Peru’s pivot to a more market-oriented model, and assessing it honestly requires holding competing truths together, as the track always insists. On one hand, the reforms genuinely ended the hyperinflation, restored a functioning currency, reopened the economy, and laid the foundation for the long stretch of growth and stability that followed — an achievement that transformed the country’s economic prospects. On the other, the stabilization imposed severe hardship on the poor in the short run, the privatizations were uneven and sometimes tainted, the reform era unfolded under a government that grew increasingly authoritarian and was later mired in corruption, and the market model did little to address the deep informality and inequality that persisted beneath the restored macroeconomic order. The Fujishock saved the currency and reopened the economy; it did not, and was not designed to, resolve the structural divide between formal and informal that Module 1 placed at the center of the story.
What turned a one-time stabilization into a durable regime was the construction of institutions designed to lock in monetary discipline permanently. The centerpiece, introduced in Module 1, is the independence of the Banco Central de Reserva del Perú (BCRP). Reformers understood that the hyperinflation had happened because the government could finance itself by printing money; the cure was to legally separate the central bank from that temptation, giving it independence and a clear, narrow mandate to maintain monetary stability rather than to fund the treasury. Over time the BCRP adopted modern inflation targeting — publicly committing to keep inflation low and within a stated range — and earned a credibility that has anchored expectations ever since.
Around the central bank grew the rest of the modern apparatus: a unified financial supervisor, the SBS (overseeing banks, insurance, and pensions, as later modules detail), a securities regulator, and a framework of prudent fiscal rules meant to keep public debt low and save windfall revenue from commodity booms for leaner times. The cumulative effect was a reputation for orthodoxy that made Peru, over the following decades, one of the more macroeconomically credible economies in Latin America — able to attract investment, borrow at reasonable rates, and weather global shocks better than many peers. This institutional architecture is the positive legacy of the trauma: a country that, having seen money destroyed, built unusually strong guardrails to protect it. The guardrails are real and worth crediting — even as the track keeps insisting that they govern the macroeconomic ceiling, not the informal floor beneath it.
The decades since the reforms have revealed one of the most striking features of modern Peru, a divergence that the comparative lens makes vivid: a remarkably stable macroeconomy coexisting with a remarkably fragile political state. On the economic side, the story is largely a success: sustained growth for long stretches, low and stable inflation, falling poverty over the boom years, declining dollarization, and a hard-won reputation for fiscal and monetary prudence. By the standards of emerging markets, Peru’s macroeconomic management has been genuinely impressive and durable.
On the political side, the story is turbulence: a rapid succession of presidents, repeated corruption scandals reaching the highest levels, recurring clashes between the executive and the legislature, impeachments and dissolutions, and bouts of unrest — a political class in near-permanent crisis. What makes this so instructive is that the two stories have, for long periods, run on separate tracks: the economy kept growing and the currency kept its value even as governments rose and fell, because the institutions of macroeconomic stability — above all the independent central bank — were insulated from the political chaos by design. This is a genuine and underappreciated achievement of institutional engineering, and also a warning. Macroeconomic stability has bought Peru time and credibility, but it cannot substitute indefinitely for political stability or for resolving the structural problems — informality, inequality, thin development — that politics has failed to address. The stable economy and the fragile state are the central paradox the capstone will return to.
Peru’s financial history is the story of how a country learned to value stability above all else. It begins with commodity dependence — silver, then guano, today copper and gold — an economy tethered to the prices of what it extracts and the demands of distant markets, inherently cyclical and externally exposed. It runs through a turbulent twentieth century of swinging models and accumulating strain, into the defining catastrophe of the late-1980s hyperinflation, which destroyed savings, hollowed out finance, and taught a generation that their own currency could betray them — the trauma behind the dollarization of Module 1.
From that catastrophe came the radical Fujishock stabilization and market reforms of the 1990s, which ended the inflation and reopened the economy at real human cost and under a troubled government, and then the construction of durable institutions of stability — above all an independent central bank — that locked in monetary discipline and made Peru an emerging-market macro success. The enduring paradox is the divergence between a stable economy and a fragile state: macroeconomic credibility insulated from political chaos, a genuine achievement that nonetheless cannot indefinitely substitute for the political and structural reform Peru still lacks. With this history in hand — and the conviction it bred that stability matters above all — the next module turns to the economy, values, and culture the system sits inside.
History is only useful if it explains the present. These questions ask what the hyperinflation, the Fujishock, and the institutions built afterwards actually determine about how Peruvian finance works today.
This module argues at the level of structure rather than statistics, which is deliberate: the shape of Peruvian finance changes slowly, while the numbers that describe it move every month.
