The capital is essential for increasing the strength and efficiency of the banking system. Indeed, it is interesting to know the determinants of bank capital. In the context of this article, we studied a sample of 18 banks in Tunisia over the period (2000…2013). We found that return on assets, net interest margin, liquidity, rate of inflation, foreign ownership and private ownership affect significantly bank capital.
