Real Effective Exchange Rate (REER) Analysis
The Real Effective Exchange Rate (REER) measures the kwanza’s value adjusted for inflation differentials against Angola’s major trading partners. While the nominal USD/AOA rate (currently 914.60) captures the headline exchange rate, the REER provides a more complete picture of Angola’s external competitiveness—whether the kwanza is cheap or expensive in real terms relative to the currencies of countries Angola trades with.
What REER Measures
The REER adjusts the nominal exchange rate for two factors:
- Bilateral exchange rates. The kwanza’s value against each trading partner’s currency, weighted by trade share.
- Relative inflation. The price level in Angola versus each trading partner. If Angola’s inflation (currently 15.7%) exceeds a partner’s inflation, the kwanza is appreciating in real terms even if the nominal rate is depreciating—because Angolan goods are becoming relatively more expensive.
A REER above 100 (using a base-year index) indicates the currency is overvalued in real terms relative to the base period. A REER below 100 indicates undervaluation.
Angola’s REER Trajectory
| Period | REER Trend | Explanation |
|---|---|---|
| 2012–2017 (peg era) | Significant real overvaluation | Nominal peg held steady while Angola’s inflation far exceeded trading partners. The kwanza became increasingly expensive in real terms. |
| 2018–2019 | Sharp real depreciation | The series of nominal devaluations and the float transition corrected the overvaluation. |
| 2020 | Further real depreciation | COVID-19 oil crash drove nominal depreciation faster than inflation differentials. |
| 2022 | Partial real appreciation | Nominal kwanza appreciation (strong oil prices) combined with persistent domestic inflation. |
| 2023–present | Moderate real depreciation | Nominal depreciation has outpaced inflation differentials, bringing the REER closer to estimated equilibrium. |
Key Trading Partner Weights
The REER is constructed using trade-weighted averages. Angola’s principal trading partners and their approximate weights include:
| Partner | Weight (approx.) | Currency | Inflation Differential vs. Angola |
|---|---|---|---|
| China | ~35–40% | CNY | Significant (Angola inflation much higher) |
| European Union | ~20–25% | EUR | Significant |
| United States | ~10–15% | USD | Significant |
| India | ~5–8% | INR | Moderate |
| South Africa | ~3–5% | ZAR | Moderate |
| Brazil | ~3–5% | BRL | Moderate |
Why REER Matters
Competitiveness assessment. A persistently overvalued REER signals that Angola’s exports (excluding oil, which is priced in USD) are becoming uncompetitive and that imports are artificially cheap. This is exactly what occurred during the peg era, when the overvalued kwanza discouraged domestic production and encouraged import dependency.
Policy signal. The BNA and the IMF monitor the REER as part of their assessment of whether the managed float is delivering an exchange rate consistent with macroeconomic fundamentals. A REER that diverges significantly from estimated equilibrium may prompt policy adjustments.
Investment returns. For foreign investors in kwanza-denominated assets, the REER helps assess whether current exchange rates offer value or whether further real depreciation is likely to erode returns.
Current Assessment
Angola’s REER is estimated to be closer to equilibrium than at any point in the past decade, following the substantial nominal depreciation from ~165 to 914.60 per dollar. However, with domestic inflation at 15.7% against trading-partner inflation of 2–5%, the kwanza faces continuous real appreciation pressure that must be offset by ongoing nominal depreciation to maintain competitiveness.
The BNA policy rate of 17.5% provides a positive real interest rate (approximately 2 percentage points above inflation), which supports the kwanza to some extent. However, the key variable remains oil prices—the driver of nominal exchange rate adjustment that ultimately determines the REER’s trajectory.
