Devaluation vs depreciation

Devaluation is an official decision to lower a fixed or managed exchange rate. Depreciation is when a floating currency falls because of the market. The effect on prices is similar, but the cause is different. For example, the UK devalued the pound in 1967, cutting its fixed rate from 2.80 to 2.40 US dollars.

What it means for people and businesses

Imported goods and foreign travel get more expensive, and exporters may sell more because their prices fall abroad. Debts owed in foreign currency become harder to repay, and savings held in the local currency buy less abroad.
