Digital Transformation, Risk-Adjusted Performance, and Crisis Resilience in Moroccan Banking: A 20-Year Empirical Analysis (2005–2024)

Abstract :The digital transformation of financial systems has fundamentally reshaped banking performance dynamics, risk management practices, and institutional resilience across emerging markets. This study examines how these structural mutations manifest in Morocco's banking sector through a comprehensive 20-year empirical analysis of six major institutions (ATW, BCP, BCI, BOA, CDM, CIH) over 2005–2024, using daily stock data and advanced risk-adjusted metrics. Against a backdrop of accelerating financial innovation, evolving regulatory frameworks, and the progressive digitalization of banking services, the analysis reveals exceptional performance divergence: cumulative returns range from BCP's 802.47% to BCI's 12.17%, and Sharpe ratios span from 0.4858 to 0.1170 — despite identical regulatory environments. This heterogeneity reflects the uneven capacity of Moroccan banks to leverage digital transformation, innovate their financing models, and manage risk in a rapidly evolving financial landscape. Comparative crisis analysis between the 2008 financial crisis and the COVID-19 pandemic demonstrates significantly improved sector resilience, with maximum drawdowns declining from –46% to –87% (2008) to –17% to –27% (2020), a pattern attributable in part to strengthened digital capabilities and modernized risk management instruments. Correlation and technical analyses further reveal high systematic co-movement among top performers (ATW–BCP: 0.95), limiting diversification opportunities while confirming distinct competitive positioning shaped by differential adoption of financial innovation. These findings generate actionable insights for three stakeholder groups: portfolio managers can exploit performance heterogeneity through active security selection favoring digitally advanced institutions; banking regulators should implement differentiated supervision frameworks sensitive to institutions' digital maturity and risk profiles; and bank executives can benchmark against BCP's model of integrated digital transformation and risk-adjusted value creation. The results demonstrate that institutional capacity to absorb and deploy financial innovation — encompassing digital banking, new financing instruments, and advanced risk analytics — constitutes the primary driver of long-term value creation in Morocco's evolving banking sector.
