Exchange Rates
How currency demand and supply determine exchange rates and how appreciation or depreciation affects economic agents.
How to study for GCSE Economics
Learn each definition and diagram as a causal model, practise calculations with units, apply evidence to the stated context and qualify conclusions with realistic trade-offs.
Core concepts
Concept 1
An exchange rate is the price of one currency in terms of another and can be determined by demand and supply in the foreign-exchange market.
Exam cue: State which currency is being bought or sold before shifting demand or supply.
Concept 2
Demand for pounds can arise from foreigners buying UK exports or assets; supply can arise when UK residents buy foreign goods, services or assets.
Exam cue: Show every step in a currency conversion and label the resulting currency.
Concept 3
A pound appreciation tends to lower sterling import prices and raise foreign-currency export prices, while depreciation tends to reverse those pressures.
Exam cue: Qualify the trade effect using elasticity, imported inputs, contracts, time and competitor responses.
Risk pitfalls and guardrails
Saying a stronger pound makes both imports and exports cheaper to everyone.
Guardrail: Do not stop at a definition or generic advantage: show the mechanism, keep units and diagram labels accurate, and separate board-specific paper claims from the England common core.
Reversing multiplication and division in currency conversion.
Guardrail: Do not stop at a definition or generic advantage: show the mechanism, keep units and diagram labels accurate, and separate board-specific paper claims from the England common core.
