Currency devaluation.
In plain English
Devaluation is an official government decision to reset a pegged or managed exchange rate to a weaker level against another currency. Because the rate was set by policy in the first place, changing it is an announcement rather than a market drift. The usual goals are to make exports cheaper for foreign buyers, discourage imports, and stop reserves from draining away. The cost lands on anyone who buys imported goods or owes debt in foreign currency, because both get more expensive in local money the day the change takes effect.
01Why it matters
If your income is in local currency and your loan or your medicine is priced in dollars, a devaluation raises your real bill overnight without your salary changing at all.
02The math, step by step
Say the rate moves from 10 to 12.5 per dollar, a 25 percent devaluation. A 200 dollar imported part that cost 2,000 in local money now costs 2,500. A 5,000 dollar debt goes from 50,000 to 62,500 in local money, and the borrower's income did not move.

03What this is NOT
Devaluation is not depreciation. Devaluation is a policy decision under a fixed or managed rate. Depreciation is what a floating currency does on its own when the market sells it. The result can feel similar, but the cause and the timing are not.
