Key Risk Drivers Identified (SHAP)
Integrating state-space filtering with deep learning provides a robust methodology for modelling asymmetric and tail risk in emerging foreign exchange markets. This framework offers practical value for exchange rate risk management, monetary policy surveillance, and financial stability monitoring in small open economies like Botswana, and is scalable for broader financial contexts.

Superior Predictive Performance
The hybrid Kalman Filter–LSTM model significantly outperforms standalone methods, demonstrating enhanced downside risk prediction accuracy and strong generalization across various forecast horizons. This is achieved by effectively capturing both time-varying state dynamics and complex nonlinear temporal dependencies inherent in financial data.
Key Insight: Lowest forecasting errors among evaluated models, robust to out-of-sample data, ensuring precise financial risk assessment.
Enhanced Risk Management Frameworks
By providing accurate forecasts of Maximum Drawdown (MDD), Conditional Drawdown-at-Risk (CDaR), and Downside Deviation, this framework enables financial institutions to implement more effective stress testing, capital allocation, and hedging strategies. Robust backtesting ensures statistical validity of tail risk measures, crucial for compliance and sound decision-making.
Key Insight: Statistically validated risk measures at critical quantile thresholds (e.g., 1%, 5%, 95%, 99%) provide a reliable basis for strategic risk mitigation.
Transparent Insights into Risk Drivers
Utilizing SHapley Additive exPlanations (SHAP) analysis, the model transparently identifies the most influential features driving BWP/USD volatility. Global geopolitical events (COVID-19, Russia-Ukraine conflict, Shanghai Stock Exchange crash) and regional currency dynamics (ZAR/BWP) are confirmed as primary determinants, offering actionable intelligence for policymakers.
Key Insight: Critical external shocks and regional interdependencies significantly impact exchange rate risk, while domestic temporal variables show minimal influence, guiding targeted policy responses.
Versatile and Scalable Financial Tool
The proposed hybrid methodology is highly adaptable and can be applied to a wide range of other financial assets beyond BWP/USD returns, including different currency pairs, commodity prices, and equity indices. Its bottom-up hierarchical structure ensures forecast coherence across multiple aggregation levels (weekly to yearly), making it a flexible solution for diverse market analyses.
Key Insight: The framework's modularity and robust performance in volatile financial environments make it a powerful asset for expanding risk management capabilities across an enterprise's entire portfolio.

SHAP (SHapley Additive exPlanations) analysis reveals that Botswana's BWP/USD exchange rate volatility is profoundly influenced by global systemic shocks. Key drivers include the COVID-19 pandemic, the Russia-Ukraine conflict, and the 2015–2016 Shanghai Stock Exchange crash. These events consistently push the model's predictions upward, indicating significant downside risk pressure.
Furthermore, the ZAR/BWP exchange rate shows a strong positive correlation, highlighting Botswana's regional currency interdependence with South Africa. In contrast, domestic temporal features such as week, quarter, and month have a negligible impact on exchange rate movements.
This insight is critical for policymakers to adopt adaptive and proactive monetary policies, integrating early-warning systems for geopolitical tensions and global financial fluctuations. It underscores the need for strategic hedging mechanisms to address ZAR-linked volatility and reduces reliance on conventional calendar-based interventions.
