institutions. The crises later led to a deterioration of
international stock markets, liquidity shortage of
interbank markets, and later extended in 2010, to a
sovereign debt crisis in some European countries,
such as Greece, Spain, Portugal, Italy, and. Before
the financial crisis began in the first half of 2007,
new regulations for banks were in practice in the
form of Basel II, but during the 2008 financial crisis,
only banks that have enough levels of liquidity could
resist the shortage in liquidity problems and continue
meet its obligations. This causes Basel Committee on
Banking Supervision (BCBS) to issue new banking
regulations called 12 Basel III, where these new
regulations give more attention to the management of
capital, equity, and liquidity, and was introduced as a
regulatory framework for banks, all over the world
[7].
Basel Committee in Banking Supervision [1],
defines liquidity as “the ability of a bank to fund
increases in assets and meet obligations as they come
due, without incurring unacceptable losses” [6].
Liquidity of banks is very important issue, where this
importance comes from its role of transforming
short-term deposits into long-term loans.
Banks face many problems in its operations that
make a threat to its solvency. Examples of risks that
banks may face include interest rate, market rate, off-
balance sheet, foreign exchange, and other risks.
Nevertheless, banks may continue subject to
solvency risk, when a bank is unable to generate
liquidity to pay its deposits [14]. Therefore,
commercial banks’ managements are required to give
more attention to liquidity, in order to be able to
avoid losses that appear regarding payments of
deposits when due. In the context of liquidity risk,
Saunders et al (2006) distinguish between two
sources of liquidity risk, the asset side source, and the
liability side source. The assets side of the balance
sheet may be an actual source of liquidity risk when a
bank exercises what is called, off-balance sheet
obligations. This occurs when a bank agrees for a
contract to grant a loan, where based on this this type
of contracts, customers receive an agreed amount,
and the bank is required to offer the borrowed
amount immediately on demand, where this type of
contracts needs more liquidity. In addition, the
liability side of the balance sheet may be another
source of liquidity risk. This occurs when depositors
withdraw a large amount of their deposits, where this
causes a decline in liquidity. Because of that, banks
can avoid such these difficulties and avoid incurring
additional cost, when banks keep enough levels of
liquidity. When a bank faces such liquidity problems,
whether it is an asset or a liability side cause, banks
may use its reserves if sufficient, because rarely
banks keep high amounts of liquid assets because
these liquid assets generate no interests, or very low
rate of interests. A bank facing a liquidity risk may
borrow additional funds, or liquidate some of its
current illiquid assets.
3 Prior Researches
The issue of bank liquidity is given enough attention
since the appearance of 2008 financial crises, but
before that time, bank liquidity had not been given
the required attention in researches and studies. Still,
the issue of commercial banks liquidity is below the
required attention of authors and practitioners in the
developing and Arab countries.
Laštůvková [9], carried out a study aiming to
identify the factors influencing the liquidity of
Czech, Slovak and Slovenian’s commercial banks.
The objective of the study is to determine the impact
of some possible internal and external factors on
commercial bank’s liquidity. Secondary data
covering the period 2001-2013, of a sample of
Czech, Slovak, and Slovenian banks, had collected
and analyzed. The multiple linear regression had
employed in testing the hypotheses. The results
showed that certain factors have a multiple effect on
the different forms of liquidity, while other factors
only affect specific forms of liquidity. The study also
found that small banks are more sensitive to specific
forms of liquidity, while the opposite, is the correct
for large banks. In addition, the study reveals that the
more flexible regulations, lead to more optimization.
Bansal and Bansal [2], investigated the
determinants of liquidity for determining which
among these affect liquidity of some Indian firms.
The relevant secondary data, covering the period
1999-2008, of a sample consisted of 100 textile and
chemical Indian enterprises. The stepwise regression
had used in the analysis of data, and the results
showed that cash flow, debt ratio, and free cash
flows, are significant determinants of liquidity.
The purpose of Ben Moussa’s Study [3], was to
identify the factors affecting the liquidity of Tunisian
banks. The secondary data covering the period 2000-
2010, of 18 Tunisian banks, had been collected and
analyzed. Two measures of liquidity had used in the
study including liquid assets to total assets, and total
