The Banco Nacional de Angola issued Directive No. 02/DSB/DRO/2022 to mandate standardized stress testing procedures for Angolan banking financial institutions. The directive requires institutions to conduct sensitivity analyses and report detailed results on credit, market, operational, and liquidity risks by December 31, using specified assumptions such as a 15% government bond devaluation, a 10 percentage point increase in public sector LGD, and a 1% operational loss shock. Compliance is mandatory under Law No. 14/21, with reporting due within 120 days and unresolved interpretive matters subject to the central bank's resolution.
GOVERNOR DIRECTIVE No. 02/DSB/DRO/2022
Whereas it is necessary to regulate the procedures for conducting standardized stress tests, with the aim of strengthening the Angolan Financial System, under the provisions of Articles 15 and 40 of Notice No. 08/2021 of July 5 on Prudential Requirements, Instruction No. 10/21 of July 7 on the Internal Capital Adequacy Assessment Process (ICAAP), Instruction No. 11/21 of July 7 on the Internal Liquidity Adequacy Assessment Process (ILAAP), and Instruction No. 03/22 of March 29, 2022 on Stress Tests.
In accordance with the provisions of Article 166 of Law No. 14/21 of May 19, the General Regime of Financial Institutions Law, combined with letters d) and f) of Article 31 and paragraph 1 of Article 98, both of Law No. 24/21 of October 18, the Banco Nacional de Angola Law.

ANNEX I Sensitivity Analyses
| Risk | Assumptions | Description | Impact |
|---|---|---|---|
| Credit Risk | Increase in credit default by the private sector (Companies and Retail) | Deterioration of impairment stage: 10% of Stage 1 amounts transition to Stage 2 and 15% of Stage 2 amounts transition to Stage 3 | Original Position, Accumulated Impairment, Net Income, Ratio of Non-Performing Exposures to Total Credit, Ratio of Regulatory Capital |
| Decrease in recovery rate associated with public sector exposures, due to the State's inability to fully repay its debt | Increase in LGD by 10 p.p. | ||
| Market Risk | Devaluation of the government securities portfolio | Devaluation of government securities by 15% | Net Income, RWAs, Ratio of Regulatory Capital |
| Devaluation of other assets in the trading portfolio (e.g., shares) | Devaluation of trading portfolio assets by 40% | ||
| Exchange rate fluctuation | Depreciation/appreciation of the exchange rate by 25% | ||
| Operational Risk | Realization of extraordinary losses associated with operational risk, namely internal and external frauds, penalties for compliance infringements related to anti-money laundering procedures and financial conduct. | Extraordinary loss corresponding to 1% of total Regulatory Capital. | Net Income, Regulatory Capital, Ratio of Regulatory Capital |
| Liquidity Risk | Reduction in deposits and credit defaults | Reduction in deposits and credit defaults in accordance with Section 2.3 of this Annex | Survival Period, Liquidity Flow Mismatch |
2.1. Survival Period The survival period is evaluated using the Institution's stock of liquid assets and corresponds to the number of days during which it ensures the liquidity flows (added to its high-quality liquid asset stock) necessary to meet its payment obligations. This measurement is performed over a maximum time horizon of 180 days. Thus, for each of the 180 days, the following must be calculated:
Liquidity Position (t) = Liquid Asset Stock (t=0) - Cumulative Net Liquidity Flows (t) + Liquidity Reserve (t)
where Liquid Asset Stock (t=0) corresponds to the stock of liquid assets held by the Institution as of the reference date, after applying the weights established in Instruction No. 14/21 of September 27 on Liquidity Risk. The reserve value as of the reference date is kept constant in determining the net position of each day t.
The survival period will then correspond to the number of days elapsed between the reference date and the day prior to the day when cumulative net liquidity flows plus the liquidity reserve become negative, i.e.:
Liquidity Position (t=0) = Liquid Asset Stock (t=0) + Liquidity Reserve (t=0)
... Liquidity Position (t=n-1) = Liquid Asset Stock (t=0) + Cumulative Net Liquidity Flows (t=n-1) + Liquidity Reserve (t=n-1) > 0
Liquidity Position (t=n) = Liquid Asset Stock (t=0) + Cumulative Net Liquidity Flows (t=n) + Liquidity Reserve (t=n) < 0
Number of days of survival = n-1
2.2. Liquidity Flow Mismatch The mismatch of liquidity flows across different maturity buckets aims primarily to anticipate any significant discrepancies between the maturity of obligations and the maturity of the Institution's assets. The objective is to compare, for each time interval, the difference between inflow and outflow.
Similar to the survival period, the liquidity flow mismatch across different maturity buckets is calculated over a maximum horizon of 180 days. For the calculation, projections of inflow and outflow across different horizons and time scenarios are used.
2.3. Description of Assumptions
Base Scenario For the purpose of calculating the survival period and liquidity flow mismatches, in the base scenario, Institutions must determine inflows and outflows according to the realization of their internal forecasts. Institutions must describe the assumptions applied in point 7 of Annex II.
Stress Scenario In addition to the assumptions applied in the base scenario, within the scope of the stress scenario, Institutions must consider the following assumptions:
| Description of Stress Scenario |
|---|
| Cash Outflow |
| 1 Demand Deposits |
| 1.1 Non-bank financial institutions: Daily reduction rate of 0.25%* |
| 1.2 Non-financial institutions: Daily reduction rate of 1%* |
| 1.3 Individuals: Daily reduction rate of 0.5%* |
| 2 Time Deposits |
| 2.1 Non-bank financial institutions: No renewal (natural maturity) |
| 2.2 Non-financial institutions: No renewal (natural maturity) |
| 2.3 Individuals: No renewal (natural maturity) |
| 3 Other Deposits |
| 3.1 Non-bank financial institutions: If at sight, daily reduction rate of 1%*, otherwise no renewal (natural maturity) |
| 3.2 Non-financial institutions: If at sight, daily reduction rate of 5%*, otherwise no renewal (natural maturity) |
| 3.3 Individuals: If at sight, daily reduction rate of 2.5%*, otherwise no renewal (natural maturity) |
