Imported Inflation
When a weaker currency or higher foreign prices push up domestic costs.
Simple Explanation
Imported inflation happens when things a country buys from abroad become more expensive — usually because foreign prices rise or the local currency gets weaker. If you import most of your oil and the currency drops, fuel costs more, which makes everything that uses fuel cost more too.
In Detail
Imported inflation occurs when higher foreign prices, commodity costs, or currency depreciation increase the domestic cost of imported goods and inputs. It is a particularly important channel for import-dependent economies, where it can account for a substantial portion of total CPI movement independent of domestic demand conditions.
Why It Matters
Imported inflation is one of the most important transmission channels for countries that depend heavily on foreign goods and energy. When a country's currency weakens or global commodity prices rise, the cost of everything it imports goes up — and those higher costs flow through to domestic prices. This is especially important for countries like India, which imports roughly 85% of its crude oil, or for any economy that relies on imported manufactured goods.
Key Ideas
Currency Weakness → Higher Import Costs
When a currency like the Indian rupee weakens against the US dollar, every dollar-priced import becomes more expensive in rupee terms. A 5% depreciation means oil, electronics, and other imports cost 5% more in local currency — even if the global dollar price hasn't changed.
Commodity Price Spikes
Even if a currency stays stable, a global rise in oil, food, or commodity prices directly increases import costs. Countries that produce less than they consume are most exposed.
Pass-Through to Consumers
Higher import costs don't stay at the border. They flow through supply chains: fuel costs raise transportation prices, imported inputs raise manufacturing costs, and eventually consumer prices rise.
Central Bank Response
Imported inflation creates a dilemma for central banks: raising rates can support the currency and reduce imported inflation, but it also slows domestic growth. This tradeoff is a key challenge for emerging-market central banks.
