Inflation has a peculiar characteristic: it is both one of the most closely measured economic phenomena in the world and one of those whose perception most stubbornly escapes statistics.

National statistical institutes calculate indices. Central banks monitor monthly variations. Economists distinguish between headline inflation, core inflation, base effects and expectations. Governments scrutinize movements of a few tenths of a percentage point with almost clinical attention. But for households, inflation never appears in the form of an index. It appears in the price of bread, fuel, rent, electricity, an airline ticket or a restaurant meal.

That gap explains part of the economic unease of the 2020s.

After the global shock that followed the pandemic, major economies gradually moved away from the exceptional inflation rates reached in 2021, 2022 and 2023. Yet the repeatedly announced return to normal has never really looked like a return to the world that existed before. By June 2026, annual inflation across the OECD still stood at 4.2%. Food inflation was 3.4%, core inflation 3.6%, and energy inflation 11.7%. Behind those averages lay considerable dispersion: nine OECD countries had inflation at or below 2%, while others were still facing much stronger price increases.

The world is therefore no longer confronting a single, homogeneous inflationary wave.

It is confronting multiple inflations.

The Great Misunderstanding of Disinflation

To understand the current landscape, one distinction matters above all.

Disinflation is not deflation.

When inflation falls from 9% to 3%, prices generally do not fall. They continue rising, only more slowly. A family that saw its cost of living increase sharply between 2021 and 2024 does not recover its former purchasing power simply because annual inflation returns to 2% or 3%.

Higher prices remain embedded in the general price level.

That statistical mechanism explains why economists can declare victory over inflation while large parts of the population do not experience it as such. The inflation rate measures the speed of change; consumers remember the level.

That divergence has deeply marked Western economies. In the United States, consumer prices were still rising by 3.5% year on year in June 2026, even after a significant monthly decline partly driven by lower energy prices. Inflation excluding food and energy was more moderate, at 2.6%, but shelter costs were still up 3.3% over the year.

In the euro area, the path has been different but the conclusion similar. After the enormous energy disruptions caused by the breakdown of Russian supplies and the restructuring of Europe’s energy market, inflation had fallen sharply. Yet it climbed back to 2.9% in July 2026 according to Eurostat’s flash estimate. Energy prices were then rising by 10% year on year, while services inflation stood at 3.3%.

The numbers change.

The vulnerability remains.

A Decade That Had Forgotten Inflation

The current situation appears even more striking because the developed world had emerged from an almost opposite era.

For much of the 2010s, central banks in advanced economies worried less about excessive inflation than about its absence. Interest rates were extremely low, sometimes negative. Asset-purchase programs multiplied. In Japan and Europe, monetary authorities struggled to push inflation up toward their targets.

Then, in only a few years, the problem changed completely.

The pandemic simultaneously disrupted supply and transformed demand. Lockdowns interrupted production chains, congested ports, created shortages of components and dislocated logistics networks optimized over decades around the principle of just-in-time delivery. At the same time, governments deployed massive fiscal support and central banks maintained extraordinarily accommodative monetary conditions.

When economies reopened, demand returned faster than some production capacity.

Then the war in Ukraine hit energy, agricultural and fertilizer markets. European gas, oil, grain and many other commodities transmitted the shock across thousands of value chains.

Inflation was no longer only monetary, energy-driven or logistical.

It had become systemic.

And when the initial disruptions began to fade, part of the price pressure had already spread into wages, rents, services and inflation expectations.

That was the moment when central banks abruptly changed direction.

The Price of Stability

The Federal Reserve, the European Central Bank, the Bank of England and many other institutions raised interest rates at a pace that would have seemed improbable only a few years earlier.

The logic was conventional: slow credit growth, moderate demand, prevent inflation expectations from becoming unanchored and, if necessary, accept slower economic growth in order to preserve monetary stability.

But higher interest rates do not produce oil. They do not build housing. They do not reopen a blocked maritime strait, manufacture semiconductors or harvest wheat.

Monetary policy acts primarily on demand and financial conditions. Yet a growing share of contemporary inflationary pressure also comes from supply.

That is where the problem becomes political.

A central bank can make mortgages more expensive to slow the economy. It cannot stop a war from raising energy prices. It can weaken investment demand. It cannot eliminate the effect of drought on harvests. It can weigh on wages and employment. It cannot instantly rebuild a fragmented industrial supply chain.

Fighting inflation therefore becomes an arbitration between different forms of economic pain.

America: Inflation After Inflation

In the United States, the shock of the 2020s produced a political transformation as significant as the economic one.

Strong domestic demand, government transfers, tight labor markets, logistics disruptions and later energy shocks combined to produce an inflationary surge not seen for decades. The disinflation that followed was substantial, but it did not erase the cumulative increase in the cost of living.

The American case illustrates perfectly the difference between macroeconomic data and social experience.

A household does not necessarily compare the price of groceries with the previous month. It compares it mentally with what the same basket cost three or five years earlier. Likewise, a young household trying to buy a home is not only concerned with current inflation. It simultaneously faces the level of property prices and the cost of borrowing.

Inflation can therefore fall while leaving behind an economy that still feels structurally more expensive.

And the memory of prices eventually becomes political.

Europe: The Return of the Energy Constraint

Europe experienced a different kind of inflation.

Its energy dependence, particularly visible after Russia’s invasion of Ukraine, exposed households and businesses directly to fluctuations in international markets.

Governments absorbed part of the shock through price caps, subsidies, tax reductions and other interventions in energy markets. These policies limited the immediate transmission to consumers, but they also transferred part of the cost onto public finances.

The European experience is a reminder of a basic reality: a country’s inflation rate does not depend solely on monetary policy.

It also depends on its energy geography, electricity mix, infrastructure, dependence on imports, tax system, wage-setting mechanisms and even the structure of its housing market.

Two countries sharing the same currency can therefore experience inflation in markedly different ways.

The currency is common.

The real economy never is.

China: When the Problem Is Almost the Opposite

At the other end of the spectrum stands China.

While much of the world was trying to contain prices, Beijing had to deal for years with relatively weak domestic demand, a prolonged property crisis, pressure on producer prices and the risk of a deflationary dynamic.

In July 2026, China’s consumer price index was rising by only 0.5% year on year. Food prices were down 1.5%, while inflation excluding food and energy stood at 0.9%. Over the first seven months of the year, average CPI inflation was just 0.9%.

At first sight, such low inflation might seem enviable.

It is not necessarily so.

Persistently weak inflation can signal insufficient demand. If companies expect prices to remain weak, they may cut investment. If households believe certain goods will be cheaper tomorrow, they may postpone purchases. And when prices stagnate while debts remain nominally unchanged, the real burden of debt increases.

Excessive inflation destroys purchasing power.

Deflation can paralyze an economy.

Between the two lies the narrow zone of stability that central banks seek.

Japan: The Paradox of an Inflation Long Desired

Japan offers yet another story.

For decades, the Japanese economy lived with extremely low inflation and, at times, outright deflation. The Bank of Japan experimented with extraordinary monetary policies to generate what other central banks were trying to prevent: a sustained rise in prices accompanied by stronger wage growth.

The emergence of higher inflation in the 2020s therefore had a very different meaning.

What constitutes a problem in Ankara or Buenos Aires can, within limits, be interpreted in Tokyo as evidence that an economy is finally escaping a deflationary equilibrium that lasted for a generation.

In June 2026, Japanese inflation stood at 1.7%, among the lowest rates in the G7.

The same number never tells the same story in every country.

Turkey: When Inflation Becomes a System

Turkey takes the discussion to another level.

In July 2026, consumer prices were still rising by 31.75% year on year. Food prices were up 37.53%, while the category including housing, water, electricity, gas and other fuels increased by 40.32%. These rates were far below earlier peaks — annual inflation had still been 61.78% in July 2024 — but they continued to describe an economy in which price instability deeply shapes everyday decisions.

At such levels, inflation gradually ceases to be simply a macroeconomic variable.

It changes behavior.

Companies shorten pricing horizons. Households look for ways to protect savings. Contracts are renegotiated more frequently. The national currency itself becomes an object of arbitrage. Property, gold, foreign currencies and other assets may be sought less for their return than for their perceived ability to preserve value.

Inflation then starts producing its own mechanisms of persistence.

The more economic agents expect prices to rise, the more they adapt their behavior to that expectation. And the more those behaviors help reproduce the very inflation they fear.

Monetary credibility becomes an economic resource.

Argentina: Living With a Currency That Slips Away

Argentina pushes this logic even further.

Few modern societies have accumulated such extensive experience of monetary instability. Devaluations, fiscal deficits, monetary financing, exchange controls, debt restructurings and repeated losses of confidence in the national currency have gradually shaped economic behavior.

In an economy suffering from chronic inflation, prices stop being durable information.

They become temporary signals.

Households spend more quickly. Companies constantly adjust their prices. Savers look for foreign currencies or assets capable of preserving value. Wage negotiations become continuous. Time itself acquires an economic cost.

The strong disinflation more recently achieved is therefore more than a statistical improvement. In June 2026, Argentina’s CPI was still rising by 1.9% in a single month.

Bringing inflation under lasting control means rebuilding something far harder to create than money itself: confidence in that money.

In Emerging Economies, the Exchange Rate Enters the Shopping Basket

For many emerging and developing countries, inflation has an additional dimension: the national currency.

An economy dependent on imported oil, grain, medicine, machinery or fertilizer can experience rising prices even when domestic demand remains weak.

A depreciating exchange rate makes imports more expensive.

Fuel prices rise. Transport becomes costlier. Agricultural inputs increase. Companies pass those costs on. Workers demand compensation. The central bank may raise interest rates to defend the currency and contain inflation.

An external shock gradually becomes domestic.

This mechanism is particularly important in many African economies where food represents a much larger share of household budgets than it does in richer countries.

A global increase in the price of wheat or oil therefore does not mean the same thing in Paris, Lagos, Cairo or Nairobi.

In a high-income economy, it may reduce savings or alter discretionary consumption.

For a much poorer household, it can directly affect the quantity or quality of food available.

The same percentage of inflation does not carry the same social cost.

Inflation Is Also a Question of Class

Price indices necessarily rely on average consumption baskets.

But no household consumes exactly the average basket.

A lower-income family generally spends a greater proportion of its income on food, housing, energy and transport. A wealthier household has more diversified consumption and greater saving capacity.

When inflation is concentrated in essential goods, it becomes mechanically more regressive.

Two people living in the same country can therefore experience two different inflations.

A homeowner does not experience rising rents in the same way as someone looking for an apartment. A person who drives every day does not experience an oil-price surge in the same way as someone who works from home. Someone whose wealth is invested in assets that may appreciate has protection mechanisms unavailable to a worker living mainly on current income.

Inflation silently redistributes wealth.

Between creditors and debtors.

Between owners and tenants.

Between workers whose wages are indexed and those whose wages are not.

Between generations.

Between states capable of subsidizing a shock and those with little fiscal room.

That is why inflation so quickly becomes political.

Geopolitics Returns to Prices

For several decades, globalization exerted powerful disinflationary forces.

Production moved toward the most competitive regions. Value chains were optimized. Logistics costs fell. China integrated into the world economy. Hundreds of millions of workers entered global production networks. Companies searched for the cheapest supplier, sometimes on the other side of the planet.

That model has not disappeared.

But it is increasingly constrained by another logic.

Governments now speak of industrial sovereignty, friend-shoring, de-risking, energy security, critical minerals, strategic capacity and supply-chain resilience.

Resilience has a price.

Building two supply chains instead of one may be safer, but it is rarely cheaper. Producing domestically a component that was previously imported may strengthen sovereignty while raising costs. Maintaining strategic inventories reduces vulnerability to disruption but ties up capital.

The world is gradually rediscovering that part of its low inflation was obtained in exchange for deep interdependence.

It now wants to reduce that interdependence without giving up the prices that interdependence made possible.

That equation will be difficult.

Climate Enters the Price Index

Another force is acting more slowly but may become structural.

Climate change is already affecting agricultural yields, water availability, infrastructure, insurance and some energy systems. Droughts, floods, wildfires, heat waves and harvest failures can all produce temporary shocks in food prices.

Taken individually, each event may appear temporary.

Their multiplication may not be.

The energy transition itself has a complicated relationship with inflation. In the long term, more diversified energy systems that rely less on imported fossil fuels may reduce some vulnerabilities. In the short term, however, the infrastructure required for the transition demands enormous quantities of copper, lithium, nickel, grid equipment, industrial machinery and capital.

Decarbonization has an upfront cost.

The absence of decarbonization has another.

The Return of the Physical World

One of the most important lessons of inflation in the 2020s may be the brutal return of the physical world to economic thinking.

For years, advanced economies could give the impression that wealth was primarily about finance, services, software and intangible assets.

Then a series of events reminded them that everything still rests on material infrastructure.

A stranded ship can disrupt an industrial chain.

A closed pipeline can alter the inflation rate of an entire continent.

A failed harvest can trigger social tension.

A semiconductor plant can become a geopolitical asset.

A maritime strait can determine the price of oil.

An inadequate power grid can slow a technological revolution.

Inflation is often the price at which an economy discovers its own dependencies.

A New Normal?

The International Monetary Fund now expects global headline inflation to edge up slightly in 2026 before resuming its decline in 2027. The institution continues to highlight risks linked to commodity prices, geopolitical tensions, financial conditions and fragmentation of the global economy.

The question is therefore no longer simply when inflation will return to 2%.

It is whether the economic environment that made the great moderation of previous decades possible still exists.

The 2010s combined deep globalization, relatively accessible energy, weak wage growth in several advanced economies, abundant capital, highly optimized supply chains and considerable confidence in the geopolitical stability of major trade routes.

The 2020s present a different landscape.

States are rearming. Industrial policy is returning. Trade barriers are multiplying. Supply chains are being reorganized according to geopolitical criteria. Investment requirements in energy, infrastructure, defense and artificial intelligence are becoming enormous. Aging societies are gradually changing the balance between workers and retirees. Public finances carry high debt burdens. And conflicts can at any moment disrupt energy, commodity or maritime transport markets.

None of these forces guarantees persistently high inflation.

But together, they make the world less naturally disinflationary than it once was.

The Price of the World

There is, ultimately, no single global inflation.

There is an archipelago of inflations connected to one another.

America is dealing with the aftermath of powerful demand and the cost of housing. Europe remains exposed to its energy environment. China is often trying to revive prices rather than suppress them. Japan is attempting to convert moderate inflation into sustained wage growth. Turkey is pursuing a difficult disinflation after years of instability. Argentina is trying to rebuild confidence in the very idea of its currency. Much of the emerging world, meanwhile, continues to absorb the price of commodities, the price of the dollar and the price of its own monetary vulnerabilities.

These stories appear different.

Yet they describe the same transformation.

Inflation is not only the amount of money chasing the amount of goods. It is also a reflection of a society’s productive structure, demographics, energy system, institutions, currency, commercial dependencies and position in the international system.

It reveals the vulnerabilities that growth can hide.

And when it returns, it forces societies to choose what they most want to protect: purchasing power, employment, growth, the currency, public finances or sovereignty.

For decades, part of the world had come to treat price stability as an almost natural characteristic of modern economies.

The 2020s have reminded us that it never was.

Stability has conditions.

And when the world changes, its price changes with it.
