Basel III is a global regulatory standard that aims to strengthen bank capital requirements and introduce new regulatory requirements on bank liquidity and leverage. It was developed in response to deficiencies in previous regulations that contributed to the global financial crisis. The goals of Basel III include improving the banking sector's ability to absorb shocks from financial and economic stress, reducing risks, and strengthening transparency. Key changes under Basel III include higher and better quality capital buffers, introduction of leverage ratio, liquidity coverage ratio, net stable funding ratio, and capital surcharges for systemically important banks.
