SUMMARY
Today banking industry is considered as one of the most important sections in economy. Banks facilitate commerce and business by organizing receipts and payments, and provide the basis for economic growth by equipping large and small amounts of savings and leading them toward manufacturing corporations which in turn requires correctly managing liquidity. One of the most important challenges that the banks are faced with is that most of the resources of the banks is supplied from short term deposits, while bank facilities are used to invest in assets which have a low degree of liquidity. Due to the importance of this topic at present, the effect of total capital on the liquidity of banks listed in Tehran Stock Exchange has been investigated from 2010 to 2014. The statistic sample includes 18 commercial banks which were selected by systematic elimination. We used linear regression and correlation to investigate the research hypotheses. Required data was obtained from Bourse (exchange) official website as well as Rahavard-e-Novin software, and then initial processing was done through Microsoft Excel. For data analysis and hypothesis testing Eviews software was used. The experimental evidence from data indicates that the degree of total capital has a positive meaningful effect on liquidity of the banks listed in Tehran Stock Exchange.
