The Global Centre for Risk and Innovation (GCRI)
Developing economies are exposed to shocks from abroad: swings in commodity prices, falls in export demand, sudden stops in capital flows, remittance changes and tighter global finance. These shocks transmit through trade, finance and confidence into output, jobs and public budgets. This page sets out how external shocks transmit, how exposure is measured, and what evidence serves the finance ministries and central banks that manage them.

External shocks are disturbances originating abroad, such as commodity price swings, falling export demand, capital flow reversals and tighter global finance, that affect a domestic economy. They transmit through trade, finance and confidence into output, jobs and budgets, and poor households absorb much of the impact.
For trade and external shocks, in GCRI's spatial-intelligence reading, the map opens on night lights, population density and true-colour imagery with true colour from NASA GIBS, framed on Africa; every other NASA layer, live feed and forecast waits in the layer list.

Layers and dates
Exports, imports and macroeconomic exposure. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Economies that rely on a few commodity exports see income, the exchange rate and public revenue rise and fall with world prices.
Foreign investors withdraw quickly when global risk appetite falls, raising borrowing costs and pressuring currencies.
Currency depreciation raises the local cost of foreign-currency debt, weakening firms, banks and governments at the same time.
Higher import prices for food and fuel, job losses and lower remittances fall hardest on poor households.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Terms of trade | The ratio of a country's export prices to its import prices, measured as an index. |
| Sudden stop | An abrupt fall in foreign capital inflows to a country. |
| Reserve adequacy | Whether foreign exchange reserves are sufficient to absorb external shocks. |
Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.
| Indicator | Unit | Cadence | Source type | Label |
|---|---|---|---|---|
| Commodity export concentration | share of top commodities in exports | annual | Trade data | OFFICIAL |
| Terms of trade | index | quarterly | Price and trade statistics | OFFICIAL |
| International reserves | months of imports | monthly | Central bank data | OFFICIAL |
| External debt | percent of GDP | quarterly | External debt statistics | OFFICIAL |
| Portfolio capital flows | currency units | monthly | Balance of payments | OFFICIAL |
| Remittance inflows | percent of GDP | annual | Balance of payments | OFFICIAL |
The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.

Commodity-exporting economies face terms-of-trade shocks: when prices of their main exports fall, export revenues, public revenues and growth fall with them. Commodity price cycles have been a recurrent source of boom and bust, and windfalls in good times can encourage spending that is hard to reverse.
Financial channels can be fast. When global interest rates rise or investors become risk-averse, capital may leave developing economies, currencies weaken, and debts denominated in foreign currency become more expensive to service. These pressures can coincide with higher import prices.
Real channels include falls in demand for exports, tourism and remittances during global downturns, and supply disruptions that raise import costs.
Models of how external variables affect output, prices and balances, using econometrics. Structural change can make past relationships unreliable.
Measures of export and import concentration. Data on services and informal trade are weak.
Tracking current and capital account flows. Data are revised and some flows are unrecorded.
Testing combined shocks to commodity prices, demand and interest rates. Scenarios illustrate, they do not forecast.
External shocks interact with domestic conditions, so similar shocks have different effects in different economies.
