  • The study period was limited to 2014–2022, which may not capture long-term trends. Based on the findings of the study, the following recommendations are made: Deposit money banks should maintain an optimal level of liquidity that ensures they can meet shortterm obligations without holding excessive idle funds that reduce profitability. Banks should adopt efficient liquidity management strategies, including proper cash flow forecasting and asset-liability management, to balance liquidity and profitability.

  • The study identifies the challenge of distinguishing between delayed and instantaneous spillovers in the context of bank connectedness. The analysis highlights the challenge of capturing the directionality and network nature of spillovers using traditional methods such as correlation analyses or simple regressions. The paper notes the challenge of examining the dynamics of African banking systems, particularly in the context of global return transmission, due to the lack of empirical research in this area.
