ABSTRACT
This project is titled Statistical Analysis on savings and loans at Guaranty Trust Bank (GT
Bank) Kaduna from 2010 to 2024. The objective of the study is to determine the significance of
loan and savings rates, assess the correlation between the two variables, and develop a
regression model to predict savings based on loan rates. Secondary data from GT Bank’s
financial reports were analysed using the Statistical Package for the Social Sciences (SPSS).
Descriptive statistics, correlation analysis, and linear regression were employed to evaluate
the relationship. The results indicate that while there is a moderate positive correlation (r =
0.536) between savings and loans, the relationship is not statistically significant (p = 0.101).
Additionally, the regression analysis revealed that only 28.7% of the variation in savings can
be attributed to loan rates, with the regression model found to be statistically insignificant (p
= 0.397). These findings suggest that GT Bank’s savings mobilization is not solely dependent
on loan disbursement, highlighting the influence of other factors such as interest rates,
economic conditions, and customer preferences. The study therefore recommends, improve
loan accessibility, monitor external Economic factors, and enhance financial education. This
study contributes to the understanding of financial intermediation in Nigerian commercial
banks, offering insights for bank management, policymakers, and future researchers. It
emphasizes the need for diversified strategies to enhance both savings and loan performance,
ensuring sustainable financial growth.

CHAPTER ONE
1.0 INTRODUCTION
1.1 Introduction
Commercial banks play a pivotal role in the economic growth of any nation by mobilizing
savings and providing loans that drive investment and consumption. Savings represent a
crucial source of funds that banks utilize to extend credit to individuals, businesses, and
process, as banks rely on deposits to meet the borrowing needs of their customers.
In Nigeria, commercial banks are vital players in the financial sector, with institutions
such as Guaranty Trust Bank (GT Bank) leading the charge in financial intermediation.
Established in 1990, GT Bank has grown into one of the country’s most reputable
financial institutions, known for its innovative products, robust customer service, and
Bank serves a diverse clientele, ranging from individuals and small businesses to large
corporations. The bank’s ability to effectively mobilize savings and extend credit directly
impacts its financial performance and overall contribution to the local economy.
Despite the significance of savings in facilitating lending, the extent to which savings
influence loan disbursement remains a subject of ongoing debate. While some studies
suggest a strong correlation between savings and loans, others argue that additional
factors, such as interest rates, government regulations, and economic conditions, also

provides insights into the bank’s lending behavior and informs strategic decision-making.
This study aims to analyze the correlation and regression relationship between savings
and loans in GT Bank Kaduna from 2010 to 2024. By examining historical data, the
research seeks to determine whether changes in savings levels significantly impact the
volume of loans disbursed. The analysis will be conducted using the Statistical Package
for the Social Sciences (SPSS), a robust software tool widely used for statistical analysis.
SPSS will facilitate the computation of correlation coefficients and regression models,
ensuring accurate and reliable results (Pallant, 2020). The findings of this study are
The success of commercial banks largely depends on their ability to mobilize savings
and provide loans to individuals, businesses, and organizations. Savings act as the
primary source of funds for lending, while loans generate revenue through interest, thus
extent to which savings influence the volume of loans disbursed remains a subject of

-2-
lending, it is unclear whether changes in savings directly impact the volume of loans
granted by GT Bank Kaduna. For instance, periods of high savings do not always
translate into increased loan disbursements, raising questions about the factors
influencing the bank's lending decisions (Nwakoby & Ijeoma, 2020). Additionally,
external factors such as inflation, interest rates, and economic conditions may also affect
the correlation between savings and loans, complicating the relationship further.
between savings and loans within the context of GT Bank Kaduna. Existing studies on
financial intermediation in Nigeria have largely focused on the banking sector as a whole,
without considering individual banks or regional differences. This gap in the literature
underscores the need for a focused investigation that explores whether variations in
savings levels significantly influence the volume of loans disbursed by GT Bank Kaduna.
This study seeks to address these gaps by conducting a comprehensive analysis of the
correlation and regression relationship between savings and loans at GT Bank Kaduna
from 2010 to 2024. By utilizing the Statistical Package for the Social Sciences (SPSS)
for data analysis, the research aims to provide empirical evidence on the strength and
direction of the relationship between savings and loans, offering valuable insights for the
bank’s management, policymakers, and other stakeholders. The findings of this study
will not only enhance the understanding of GT Bank’s financial intermediation process

2.1.1 Savings
Savings refer to the portion of income not consumed and set aside for future use. In the
context of commercial banks, savings are deposits made by individuals and businesses,
which banks use to provide loans and generate profit through interest (Mishkin, 2019).
These deposits are crucial for the bank's liquidity and ability to extend credit, directly

portion of their revenue (Odhiambo, 2020). The availability of loans is heavily dependent
Financial intermediation refers to the process through which banks and other financial
institutions mobilize savings from depositors and channel these funds into loans for
borrowers. This process is essential for economic growth as it provides capital for
investment and consumption, bridging the gap between savers and borrowers (Nwakoby

2.1.4 Correlation and Regression Analysis
Correlation analysis measures the strength and direction of the relationship between two
variables, while regression analysis determines the extent to which one variable
influences another. In this study, correlation analysis will assess the relationship between
savings and loans at GT Bank Kaduna, while regression analysis will evaluate the
predictive impact of savings on loan disbursement using SPSS software (Pallant, 2020).
This theory, proposed by Gurley and Shaw (2020), posits that financial intermediaries
such as banks play a crucial role in bridging the gap between savers and borrowers. By
pooling savings from multiple depositors, banks can provide loans that support
Developed by Knut Wicksell, the Loanable Funds Theory suggests that the supply of
loans depends on the availability of savings, while the demand for loans is influenced by
interest rates. According to this theory, an increase in savings leads to a higher supply of
loanable funds, reducing interest rates and encouraging borrowing (Mishkin, 2019).
John Maynard Keynes argued that savings and investment are influenced by income
levels and interest rates. Higher income levels lead to increased savings, which banks can
use to provide loans. However, Keynes also noted that excessive savings without

2.2.4 Permanent Income Hypothesis
Friedman (2017) proposed that individuals base their consumption and saving decisions
on their expected long-term income rather than their current income. This hypothesis
implies that temporary changes in income do not significantly affect savings behavior,
Modigliani and Brumberg (2014) suggested that individuals save during their working
years to support consumption during retirement. This theory explains the accumulation
of savings over time and its impact on the availability of loanable funds.
Schumpeter (2021) emphasized the role of banks in creating credit beyond the deposits
they hold. According to this theory, banks play an active role in economic development
Odhiambo (2020), in his study titled Interest Rate Reforms, Financial Deepening, and
Economic Growth in Kenya, examined the relationship between interest rates, savings,
and loans. Using time series data and regression analysis, he found that financial

Adebayo et al. (2021), in their study Savings, Loans, and Economic Growth in Nigeria:
An Empirical Investigation, analyzed the correlation between savings and loans using
data from Nigerian commercial banks. The study employed Pearson correlation and
savings and loans. Their findings suggested that higher savings levels lead to increased
loan disbursements, supporting the notion that banks rely on deposits to finance lending
activities.
Aliyu (2022) examined The Relationship Between Deposit Mobilization and Loan
Disbursement in Nigerian Banks: A Case Study of GT Bank. The study used annual data
from 2010 to 2020 and employed SPSS for correlation and regression analysis. The
findings indicated a strong positive correlation between deposit mobilization and loan
disbursement, emphasizing the critical role of savings in supporting the bank’s lending
activities. Aliyu's study further revealed that efficient deposit mobilization enhances GT
