Why currency devaluation matters

It changes import costs, export competitiveness, foreign debt, inflation, reserves, and investor returns.

How it is applied

Investors assess reserve adequacy, external balances, policy credibility, parallel rates, debt currency, and controls.

Portfolio example

A peg changes from 5 to 6 units per dollar, a 20% devaluation against the dollar under that quote.

How to interpret it

Devaluation is a policy action, unlike market depreciation under a float.

Limitations and common misconceptions

Controls can prevent conversion and official rates may not be executable.
