ABSTRACT
Investigating the determinants of profitability of commercial banks has been one of the
more popular topics among researchers in banking studies. Hence, to contribute to the
existing knowledge, this study sought to analyze the extent to which investment in loans
and treasury bills influence the overall profitability of commercial banks in Uganda,
using a data set comprising 95 observations for 15 commercial banks over the period
1998-2005. The study used a longitudinal research design, based on quantitative data
generated through document analysis of commercial banks’ monthly reports and returns
to Bank of Uganda. Overall Profitability was measured using two profitability ratios
namely: Return on Assets (ROA) and Return on Equity (ROE) while the independent
variables included: volume of loans, volume of TBs, lending rates and yield on TBs.
The study found Volume of Loans and TBs having a positive correlation while Lending
Rates and average yields on TBs revealed negative correlation with ROA as an element
of the dependent variable. With regard to ROE, Loan Volume, Lending rates and Volume
of TBs showed a positive relationship while average yields on TBs indicated a negative
correlation with this element of the dependent variable. However, in the two analyses,
commercial banks’ investment volume in loans was found to be the only variable that had
a statistically significant influence in accounting for profitability of commercial banks in
