Depreciation vs Devaluation
Market-driven currency fall under flexible exchange rate versus deliberate official cut under fixed rate.
Start here
Currency depreciation is a market-driven fall in a currency’s value under a floating or managed-float regime; devaluation is an official downward reset of a currency’s peg by the government or central bank under a fixed exchange rate.
When the rupee moves from ₹74 to ₹83 per dollar in the market, that is depreciation (India has a managed float since 1993 reforms). When China or India (pre-1991) officially reset the rate overnight, that was devaluation.
Both make imports costlier and exports cheaper in foreign currency terms — but the mechanism and policy implication differ.
Side-by-side comparison
| Feature | Depreciation | Devaluation |
|---|---|---|
| Impact on exports | Cheaper for foreign buyers — boosts competitiveness gradually | Immediate boost to export competitiveness |
| Impact on imports | Costlier — widens CAD if elastic | Same — inflationary for import-dependent economy like India |
| Policy signal | May reflect weak BoP, FPI outflows, oil prices | Deliberate trade/competitiveness or crisis response |
| National accounts term | Also: capital consumption (GDP context) — homonym! | Only exchange rate meaning in external sector |
| India post-1993 | Rupee depreciates/appreciates in forex market with RBI intervention | No official devaluation — managed float adopted after LPG reforms |
| Opposite term | Appreciation (market-driven rise) | Revaluation (official upward reset under fixed rate) |

iPhone price vs 1991 rupee crisis
In 2022, FPI outflows pushed rupee from ₹74 to ₹81 per USD — market depreciation. Imported iPhones and study-abroad fees got costlier in rupee terms. Contrast July 1991: India faced BoP crisis and officially devalued the rupee ~20% in two steps under a fixed regime — a policy decision, not daily market trading. Post-LPG, rupee floats with RBI intervention — so India sees depreciation/appreciation, not official devaluation.
What this means for the exam
Depreciation = market/managed float | Devaluation = official cut under fixed peg.
Understand the difference
Homonym alert — depreciation in GDP
In national income accounting, depreciation means wear-and-tear of capital (GDP → NDP). In forex, it means currency value fall. UPSC uses both — context determines meaning.
