Purpose
The unhealthy drive for deposit in the banking sector has pushed many banks into unethical practices, thereby resulting in high-level corruption cases in the banking sector. The purpose of this study is to investigate the short- and long-run linkages between bank net interest income and deposit liabilities interacted with corruption, to establish the influence of corruption in deposit mobilisation drive of banks in Nigeria. Also, the study analysed the causal relationship between selected bank variables and fraud.
Design/methodology/approach
The study used quarterly data on selected variables from 1Q 1993 to 4Q 2017 sourced from Nigerian Deposit Insurance Corporation (NDIC) annual reports and Central Bank of Nigeria (CBN) Statistical Bulletin of various issues. Deposit Money Bank various deposit liabilities are interacted with a corruption index and used as the independent variables, while bank earnings serve as the dependent variable. Error Correction Model (ECM) and Engel Granger approach to co-integration technique were used to analyse the data.
Findings
The findings reveal that various bank deposit liabilities interacted with corruption index has a negative effect on bank profitability in the long run, though only corrupt fixed deposit is statistically significant at the 5 per cent significance level. Bank total asset, total loan and advances and fraud have a significant effect on bank profitability at 1 and 10 per cent significance level. The findings also reveal that banks profit from corrupt fixed deposit and demand deposit in the short run.

Originality/value
The literature is awash with bank lending corruption and various institutional factors such as competition among banks, credit bureau and information sharing about borrowers, bank supervisory policies, loan loss provisioning, bank ownership structure and regulatory environment and anti-corruption measures. The aspect of deposit mobilisation and corruption has not been well researched in literature; this study, therefore, fills the gap in the literature by examining the extent deposit money banks contributed to corruption in Nigeria through their cutthroat deposit mobilisation drive.
This study utilized secondary data sourced from the World Development Indicators (WDI), International Labour Organisation (ILO), United Nations Educational, Scientific and Cultural Organization (UNESCO), and the System Generalized Method of Moments (SGMM) econometric technique was used to analyze the data. Sustainable Development Goal 1, a proxy for poverty, was used as the dependent variable, while agriculture value added, employment in the agricultural sector, inequality, literacy rate, population growth rate, and gross domestic savings were the explanatory variables. The study found that both agriculture value added and employment in the agricultural sector were statistically significant in explaining poverty and negatively related to poverty in the Economic Community of West African States (ECOWAS) subregion. Therefore, based on the findings, the study recommends that the governments of ECOWAS countries should focus more on agriculture in order to become exporters of cash crops to boost their economies and increase savings that can be used to alleviate and eliminate poverty among the people.
