Imported inflation
When the rest of the world sneezes, your CPI catches a cold.
In plain words
When Russia invaded Ukraine in February 2022, European gas prices rose 10-fold within months. European central banks hadn't changed anything about their domestic policy — but European CPI hit double digits. The price shock was almost entirely imported: higher costs for energy and food that originated in global commodity markets, not in domestic wage dynamics or demand conditions. This is imported inflation: price pressure that arrives at the border in the form of higher import costs and then propagates through the economy. The World Bank Commodity Markets Outlook is the best regular assessment of the global commodity prices that drive imported inflation worldwide.
How imported inflation transmits to consumers
Imported inflation passes through in two waves. The first wave is direct and fast (1–3 months): energy bills rise, petrol costs more, imported food gets more expensive at the supermarket. The second wave is indirect and slow (3–12 months): higher energy and material costs push up manufacturing costs, which push up retail goods prices. Transport costs rise, affecting everything. Then — potentially — workers demand higher wages to compensate for the cost-of-living rise, starting a domestic wage-price dynamic on top of the imported shock. The ECB Economic Bulletin's 2022 analyses documented this transmission in detail for the euro area. The IMF working paper on exchange rates and prices provides the empirical framework.
Policy challenge: you can't import your way to 2%
Imported inflation creates a genuine policy dilemma. Raising interest rates addresses domestic demand but cannot stop foreign commodity price increases. Yet if the central bank ignores imported inflation, wages may rise in response to higher living costs, converting a temporary external shock into a persistent domestic one. The ECB, BoE, and Fed all faced this dilemma in 2022–2023. The consensus answer: "look through" direct commodity price effects but respond if second-round wage and pricing behaviour suggests the shock is becoming entrenched. The BIS Annual Economic Report 2022 provides the most thorough post-mortem of the imported inflation episode.

Common misreadings
Imported inflation is often described as "outside the control of domestic policymakers" — which is partly true but misleading. A central bank that maintains a strong currency (by keeping interest rates higher) reduces the domestic-currency cost of imports. Exchange rate management is therefore an indirect lever against imported inflation. The BIS Annual Economic Report 2022 shows how countries with stronger currencies fared better against the 2022 energy shock. Also, "imported inflation will pass" is often used to justify inaction — but if it persists long enough to feed into wages and services prices, the initially-imported shock becomes a domestic one requiring a full monetary policy response. The Bank of England Monetary Policy Reports from 2022–2023 explicitly grappled with this distinction.
Frequently asked questions
How does imported inflation differ from domestic inflation?
Imported inflation originates outside the economy — through higher prices for oil, gas, food commodities, or manufactured goods bought from abroad. Domestic inflation originates inside the economy — through stronger consumer demand, rising wages, or domestic supply constraints. The distinction matters for policy: central banks can address domestic inflation by raising interest rates (cooling demand or curbing credit). But raising rates doesn't reduce global oil prices or fix a foreign harvest failure. This is why central banks look through temporary commodity-driven inflation and focus on domestic demand and wage measures.
Which countries are most exposed to imported inflation?
Small open economies that import a high share of their consumption goods and energy are most exposed. Countries with large current account deficits (importing more than they export) and those whose currencies are weak against the dollar (since most commodities are priced in USD) face the most imported inflation. Examples: Armenia, most of sub-Saharan Africa, smaller Central/Eastern European economies. The UK experienced elevated imported inflation in 2016 (post-Brexit sterling fall) and 2022 (energy). The World Bank and IMF both track commodity import exposure by country.
How does a currency depreciation amplify imported inflation?
Most traded commodities (oil, gas, wheat, copper) are priced in US dollars. If a country's currency weakens against the dollar, imports become more expensive in domestic-currency terms — even if the dollar price hasn't changed. A 10% depreciation of the pound sterling raises the sterling cost of all dollar-priced imports by 10% before any price negotiation. Combined with a rising commodity price, the effect compounds.
